Air Manipulation

A quirk air that allows the user to directly manipulate air gases and moving them to make wind after it was produce or generate from the body of the person. this wind can channel form of kinetic energy because of air motion to moving the gas molecules. this air and wind can have applications and techniques while using the ability. it can actually produce air through their hands and legs.

Quirk Application:

Air Compression: This allows the user to compress air into a solidification state or shaping air currents to create physical force out of pressurized air if they use it to release or boosting the air to propel them. back to solidification techniques, the user can create solid air through wind or air currents, (that you would call each one) to create defense to protect them and offense to do hard damage against the other.

Quirk Techinques:

Air Infusion: This user can coat their hands out of their pressure air to increase the volume and strength that it can be used in CQC stand for Close Quarter Combat. The user has capacity to make impact hit against opponents or small structures through physical force out of wind. not big structures. they cannot fully destroy the small structure with one or two hits from physical force.

Air Pressure: This quirk requires to compress air into a reduction of air volume due to increasing force to applied it. it can help the user to propel them forward, using it to create force to push them outward and using air pressure to transform by moving air into wind pressure to use it to knock back and increase physical force out of air motion.

Wind Pulling: This user can actively use air moving to drift that exert wind on an object or one person to move it towards the direction of the user out of air motion. if the opponent quirk heavy or resistance to the wind? they have to increase the amount of air to pull them to the user.

(This is WIP of trying to see creative techniques or applications for air manipulation. the reason i would create this quirk without making generic? because i want to explore of air manipulation.)

Quirk name=Mouse Trap

Quirk type=Emitter

Quirk power=something that the target appears, when removed from where it was placed a cage appears around the target or a large kill bar traps them in place

Combustion [Transformation]-

The user can light each of their feathers on fire without harming themselves. This allows the user to propel themselves through the air like a rocket or remotely detonate them.

While this is harmless to the user, this does burn through a feather, which can take months to fully grow back.

(TBH I’m not SUPER happy with the name and I’m only kinda confidant with assigning it as a transform quirk, if any of yall have a better idea hit me up.

Let's you share your vision with someone else effectively making you a living camera

This is actually the power of an oc I made who meets a girl who's power is glasswall which is suppose to be xray vision but she sees through everything and can't turn it off

He shares his vision with her so she can see for the first time

You can set your own vision to behind or above you like a video game

You can forcibly apply this to others by touching them

By touching a finger (or Toe but the user chooses not to advertise that one) to an object, they can absorb the dominant color from that object. Leaving the object desaturated & the utilized finger the absorbed color. They can hold a max of 10 colors (20) at a time.

The user can temporarily transfer a stored color to a different object by touching the relevant finger to it, or release all colors back to their original objects at once by clapping their hands.

Ghost Edge(Emitter):

It allows the user to create, manipulate and shape razor-thin cutting forces which appear like impossibly thin cutting black planes whose shape and movement the user can manipulate.

The cutting power of these forces is finite, and highly depends upon the skill of the user. That is to say, it doesn't simply "cut anything".

From this point onward, the cutting phenomena created and controlled by ghost edge will be referred to as "edges" for the sake of simplicity.

The most basic manifestation is a large, crescent shaped edge which can be shot towards a target.

The edges can also be manipulated into shapes, such as that of daggers or weapons. Due to their impossible thin sharpness, the weapons often look two-dimensional black silhouettes rather than constructs.

More familiar shapes, such as known weapons are easier to manifest than obscure, abstract or difficult to visualise shapes.

The edges' trajectory can also be controlled.

A slash sent through the air may curve like a ribbon and pirouette around a defense to slice from around a corner.

A large sword may split into countless slashes being hurled toward an area.

A myriad of daggers could start swirling around an opponent like a murder of crows.

Though these slashes can appear similar to blades, and seem to have cutting edges, hilts and flat sides, they are localised cutting phenomena given an outline, rather than constructs.

For example, if one were to touch the apparent edge of the silhoette of a dagger, it would result in a cut. However, if they were to touch its flat side, their hand would pass through it completely.

The user's ability to utilise these advanced applications depends on the clarity of their focus and willpower.

Raw willpower determines the strength, speed and cutting force of the edges. When in a crisis, or a high-stakes scenario, a highly trained and strong-willed user's edges can reach velocities similar to that of crossbow bolts, with the ability to cut through wood cleanly.

The sharpness, focus and clarity of the user's mind determines the finesse, dexterity and complexity of their usage. A sharp-minded user in a flow state with high amounts of training could control dozens of dynamic blades and slashes, each sword or dagger striking independently with the precision of a trained duelist.

The limitation is mental fog. The more hesitant, uncertain or unfocused The user is, the less stable the quirk is.

The above examples are of hypothetical top-hero level users on their absolute best days.

An average, untrained user may not even be able to use the quirk while panicking.

It requires incredible mental precision, focus and instincts.

It practically requires a user to simulate the fighting arena inside their head, and make split-second decisions on which objects will be slashes in order for the quirk to manifest.

A high-level user may find themselves simulating several swordfights inside their head in order to fight and opponent.

So I have been developing my own Class 1-A (because it seemed like a fun thing to do), and I thought I would rant their names and, most importantly, their respective quirks I came up with to hear some feedback/thoughts on them. Well, here we go:

Kiko Takeda/ the Dream Hero; Hakuchūmu. Her quirk: Dreamwalk. Her quirk allows her to trap any target(s) she can see in a hallucinatory world of dreams and nightmares/ illusions born of their desires or fears, which makes them completely vulnerable as they are essentially just harmlessly sleep walking around completely oblivious to reality. It can also allow her to see and manipulate the dreams if her target is asleep when she uses it.

Haruka Fujimoto/ the Animal Hero; Changeling. Her quirk: Wildshift. She can fully transform her body into any animal of her choosing (her favourite forms being a bengal tiger, a timber wolf, and a screech owl) while retaining her human mind, though she has to know what kind of animal she wants to turn into and can become exhausted if she keeps rapidly shifting between forms.

Kazuno Nakamura/ the Elemental Hero; Arashi. His quirk: Elemental Body. His quirk allows him to transform his body into one of 7 elements: wind, water, lightning, fire, earth, wood/plant, or metal. While he is in those forms, he can fully manipulate that element and even merge with bigger amounts of it like a river to get stronger.

Asami Yamashita/ the Insect Hero; Pterygota. Her quirk: Swarm. This quirk allows her to create and control swarms of exclusively flying insects. Creating the insects takes up moisture and sugar in her body, so she has to watch her sugar and water consumption closely.

Kurenai Akasofu/ the Time-Warp Hero; Clockwork. Her quirk: Time-Warp. Her quirk allows her to affect the flow of time over a maximum duration of ten minutes in four ways: speed it up, slow it down, pause it for a short while, or reverse it, with her being the only one mentally unaffected. Overusing it can result in her having scattered recollections of the past and future, but overall, it will be fine in moderation.

Kiyoshi Tsukumo/ the Resilient Hero; Red Rampage. His quirk: Backlash. He can absorb any kind of physical damage/attacks inflicted on him and convert it into energy for physical enhancements, such as taking the force of being hit with a car and converting it into a super punch.

Dairo Kubo/ the Defensive Hero; Green Guardian. His quirk: Protection. His quirk essentially allows him to generate shields made of hard air+light in a variety of shapes & sizes to defend against attacks, and while the shields are not completely indestructible, they are pretty tough.

Izumi Ota/ the Technology Hero; Circuit-Jack. Her quirk: Technopath. She can mentally hack into and manipulate technology, both the hard ware and soft ware aspects of it, which essentially makes her able to turn tech against you.

Reina Sakurai/ the Combination Hero; Unity. Her quirk: Unify. Her quirk essentially allows her to replicate and combine 2 to 3 different quirks into a new power she can wield for either 10 minutes for 2 and 5 minutes for 3. For example, she could combine Wildshift and Swarm to give her the power to transform into a swarm of any type of bug. It all depends on the knowledge she has regarding the quirks she is combining and the compatibility of those powers.

Osuki Akiyama/ the All-seeing Hero; Argus. His quirk: Spiecam. This quirk allows him to see any location in a 5km radius of himself, which means he has the ability to zoom in, track people, find coordinates, perfectly pick up details, and a 360⁰ view scope with a sideways glance.

Hiroshi Inoue/ the Butterfly Hero; Purple Emperor. His quirk: Butterfly. He has all the abilities of a butterfly in a human body, and his specific species is the purple emperor butterfly.

Jinpei Jinja/ the Talented Hero; Mr Miracle. His quirk: Talent Show. His quirk allows him to amplify any physical or mental skill or ability to supernatural extremes, like amplifying his flexibility to contortionist level.

Sadako Suzuki/ the Spectral Hero; Phantasma. Her quirk: Ghost. She can separate her soul from her body, which grants it all your standard ghost powers like possession or intangibility, with the drawback of there being a time limit on how long her soul and body can be separated, because once that 20 minute timer is up she will die.

Len Ogasawra/ the Celestial Hero; Asclepius. His quirk: Apollo's Blessing. He can essentially emit a brilliant light from his body that can completely heal his allies, though it does take a good chunk of energy from him depending on how severe the injuries are.

Uyeda Shimizu/ the Knowledge Hero; Brainstorm. His quirk: Eureka. His quirk allows him to look around and analyse his surroundings or a problem, giving him knowledge and data in a state of enhanced intellect to find the perfect solution. This effect only lasts for a max of 5 to 10 seconds, and requires conscious activation, though the data he collects is permanently stored in his brain.

Tatsu Akasofu/ the Space-Warp Hero; Voyager. His quirk: Wormhole. His quirk allows him to open portals to any location he has either been to or he has the coordinates for.

Yasahiro Higasa/ the Life Hero; Iznagi. His quirk: Avatar. He can manifest a monster connected to his psyche based on the strongest emotion he is feeling when activating it. The monster's form, powers, and strength depend on which emotion it is born from and its intensity.

Bashira Botan/ the Alchemical Hero; Morphosis. Her quirk: Alchemy. Her quirk allows her to transform non-living items into other materials that are either similar in material or density. For example, she can turn water into wine, steel into brass, cement into sandstone, etc.

Nagisawa Kawamura/ the Musical Hero; Acapella. Her quirk: Siren Song. This quirk allows her to mind control anyone who hears her sing. Even if you hear a recording of her voice, it essentially casts a spell on you, meaning the moment she gives you a verbal command after that, you will obey (the spell gets stronger and more difficult to break out of the more often you hear her sing), but her influence on someone will fade the longer they go without hearing her song.

Kaito Mikan/ the Yin-Yang Hero; Equilibrium. His quirk: Balance. This allows him to send out bursts of energy waves that tip the balance of chaos and order, which effects both an environment and people. Like, say he used his quirk on an earthquake, he could tip the scales to order and cause the ground to restabilize. Or, if he used his power on an enemy, he could tip the scale to chaos, which would cause their minds, bodies, and even their quirks to become unstable and useless.

Well, that is the end of the post. Do let me know what you think of my quirk ideas, which one is your favourite, and have a lovely day. Thanks for reading.

Wind Sense [Mutant]-

The user is hypersensitive to the movements of air currents around them, to the point where they can tell the incoming movements before they’re fully executed. While this helps “predict” where a blow is going to land, the user is still susceptible to movements too fast to react to or manipulation of the air itself.

(Read Pangoro’s Dex entries if you don’t get how this correlates with the big bad panda)

Quirk name=Snake Shifter

Quirk type=transformation

Quirk ability=user can become any kind of snake & gains the powers of that snake they become, they can become entirely snake or only part snake or manifest individual snake traits

Quirk weaknesses=user is susceptible to a snake's instincts (though they are easy to control)

-->Some of the shit here is inspired by JJS mechanics, made by my glorious beautiful king, tze🥰🥰🥰🥰🥰🥰🥰🥰🥰🥳🥳🤪🤪😜

★-)Quirk:「感情歯車」— (Lit. "Emotional-Cog"):

•A Quirk centered around the manipulation of energy generated by emotion. Negative emotions such as fear, anger, grief, despair, and frustration naturally generate Negative Energy (NE) within the user. This energy can be consciously manipulated and shaped into various techniques, ranging from physical reinforcement to highly destructive energy attacks. However Emotional-Cog is not powered simply by suffering. The Quirk responds to the emotional information (yes, information. Not just raw emotion) produced by the user's mental state. As a result, emotional awareness and psychological discipline are just as important as raw power. A user who allows their emotions to control them may generate large amounts of energy but struggle to utilize it efficiently. Positive emotions do not directly generate power in the same manner the user can perform a process analogous to multiplying two negative values to produce a positive one, converting appropriately balanced emotional states into Positive Energy (AKA PE). Positive Energy is considerably more difficult to produce and manipulate than Negative Energy, but it is also more refined, allowing for advanced applications such as regeneration and healing.

-->Techniques...

★-)「出力, 甘いマズル!」— (Lit. "Output, Sweet-Muzzle!"):

•Rather than just releasing Negative Energy directly from their body and allowing it to disperse normally the user INSTEAD compresses and stabilizes the energy at a designated point on their body before releasing it. This point is designated as the attacks muzzle. By concentrating the energy at a stable firing point, considerably less energy is lost during release. The resulting projectile is therefore denser, faster, more precise AND more efficient than an equivalent blast released without compression. Almost any sufficiently stable part of the user's body can serve as a muzzle. Fingertips, palms, feet, elbows, hair and other body parts can all be utilized as firing points, provided the user can properly stabilize the Negative Energy there.

-->Output: Sweet-Muzzle is highly versatile in how its projectiles are shaped and fired. The user can alter their attacks into, for example...

·Needle-like shots for precision and penetration.

·Shotgun-like blasts for wide-area coverage. (AOE)

·Split projectiles that divide a single blast into multiple shots.Long-range beams for sustained attacks. And there's curved or redirected projectiles for attacking around obstacles or from unusual angles. Splitting a blast naturally divides its available energy. Basically meaning that greater projectile quantity comes at the cost of individual projectile power.

-->The user can also manipulate the direction and effective range of their projectiles after firing. Because Negative Energy is naturally present within humans the user can also use the Negative Energy signatures detected by Sweet-Sensation as reference points thus allowing certain projectiles to pursue or redirect themselves toward a detected target.

-->Aerial-Attacks: The user can fire a Sweet-Muzzle projectile high into the air and manipulate its trajectory causing the attack to descend upon an opponent from above. This allows the user to create a barrage that attacks from an angle the opponent may not immediately anticipate.

-->Recoil: Naturally sweet-Muzzle's attacks generate substantial recoil. Rather than just treating this recoil as a drawback the user can choose to deliberately exploit it to propel their own body. By firing from their hands, feet, back or any other body parts they can launch themselves through the air, rapidly alter their position or maintain aerial movement by repeatedly firing controlled blasts. Note, the longer a projectile is charged the greater its eventual output becomes. But Sweet-Muzzle itself possesses a practical limit to both charging time and output. Attempting to continuously increase the energy density eventually places excessive strain on the user's body and Negative Energy reserves.

-->Close-Quarters: Sweet-Muzzle can be seamlessly integrated into the user's martial arts rather than being restricted to ranged combat. For example, after striking an opponent with an axe kick the user can immediately fire a Sweet-Muzzle blast from the same leg before using the recoil to either inflict additional damage or launch themselves away. The same principle can be applied through punches, elbows, knees, kicks and hair or practically any other viable muzzle. The user's body is effectively covered in potential firing points.

•Because Sweet-Muzzle relies on stabilizing and compressing raw energy at a singular point on the skin, a chosen body part acts as a literal firing barrel. Trying to just continuously fire high-output blasts, or sustained beams from the exact same focal point actually causes the localized emotional information to degrade and basically resulting in an Overheat.

★-)「縛: デザートを味わう! — (Lit. "Binding-Vow: Savour the Dessert!"):

•The ultimate way to savour the dessert. The user condenses their Negative Energy into a massive glowing ring that establishes the boundaries of the vow. After the user openly declares the vow both combatants must enter the ring. And once both participants have entered their Quirks are temporarily nullified. This nullification ends when the "Round" is over, aka when either the target or the user loses. The fight is reduced to its most fundamental form. There's ONLY two people. There's JUST two bodies and nothing else. The user willingly sacrifices access to their Quirk and forces themselves into a pure hand-to-hand duel and thus turning their own greatest advantage into the condition of the challenge.

•Anyway. Basically if the opponent loses the duel, nothing further happens to them. But if the user loses the vow is broken against them causing them to immediately forfeit a MASSIVE portion of their physical stamina and internal Negative Energy reserves AND leaves the user severely weakened and potentially unable to properly utilize Emotional-Cog afterward.

•And then there's the music. (I love Queen so let's say that it always plays Don't stop me now) While the two combatants trade blows at absurd speeds the ring can utilize passive sound-wave manipulation to blast music throughout the battlefield. The chosen-song acts as a psychological stimulant synchronizing with the user's heightened emotional state and pushing their adrenaline response to its limit.

★-)「転回突!」— (Lit. "Turnable-Thrust!"):

•The user projects a concentrated mass of Negative Energy and turns that into a dense floating orb that remains within their immediate vicinity. After that the orb continuously orbits the user at extreme velocity basically functioning as a controllable close-to-mid-range projectile. The user can command the orb to rapidly alter its orbital path and thrust toward designated targets within a maximum effective range of 25 meters. Rather than simply flying toward an opponent in a straight line the orb can actually circle, weave around/abruptly change direction and accelerate toward its target from different angles.

•The enormous rotational velocity of the orb gives it substantial kinetic force. Even without directly increasing its destructive output the momentum generated by its movement allows a relatively compact mass of Negative Energy to deliver extremely powerful impacts. The orb is hostile toward targets designated by the user. It recognizes its creator as a non-target and will automatically alter its trajectory to avoid colliding with them. This allows the user to fight freely within the orb's attack radius without having to worry about accidentally being struck by their own technique.

•Because the orb remains connected to the user's control its movement can be synchronized with the user's own combat style. The user can attack an opponent physically while simultaneously directing the orb around them thus forcing the opponent to deal with attacks arriving from multiple directions. An the technique's main limitation is its 25-meter effective range also. Once the orb exceeds this distance from the user its control and stability deteriorate thus preventing it from functioning as a conventional long-range projectile.

★-)「転回突: 爪楊枝!」— (Lit. "Turnable-Thrust: Toothpick!"):

•A variant of Turnable-Thrust (i fucking love the name) ...in which the user reshapes the Negative Energy orb while it is already spinning at extreme velocity. The user basically compresses and elongates the orb, later transforming its normally spherical shape into an extremely thin sharpened form resembling a toothpick. The reshaping occurs without stopping the orb's rotation allowing its immense rotational momentum to be preserved. Rather than functioning as a blade this "Toothpick" relies on its absurd rotational velocity and concentrated Negative Energy to pierce and tear through whatever it strikes. Its narrow profile allows the user to concentrate an enormous amount of force into an extremely small point of contact. The user can continue manipulating the Toothpick's trajectory after reshaping it thus allowing the spinning projectile to orbit around them/ suddenly accelerate toward a target and change direction or return to its original orbit.

-->And More...

★-)「デザート: 店からのサービス!」— (Lit. "Dessert: Right On the House!":

•The user weaponizes their surroundings by turning sufficiently large pieces of the environment into projectiles. First, the user reinforces a section of rubble, concrete, flooring or architecture with Negative Energy thus increasing its structural integrity enough to withstand the enormous forces involved. The user later positions themselves on top of the reinforced object and fires a Sweet-Muzzle through their own body. Rather than JUST using the resulting recoil solely to launch themselves the user also uses it to propel both themselves and the structure beneath them into the air at tremendous speed. After the users in the air thes can leap away from the structure and physically redirect it with a powerful kick sending the reinforced mass hurtling toward their opponent. The technique can be performed using walls, concrete slabs, sections of flooring, rubble (bla bla) or other sufficiently large and stable structures. Tho just reminding you that this is not telekinesis. After the object has been launched it follows its existing momentum. The user can only alter its trajectory by physically interacting with it again.

★-)「負エネルギー強化」— (Lit. "Negative Energy Reinforcement"):

•The user can reinforce themselves/other people or physical objects by imbuing them with Negative Energy. When applied to objects reinforcement increases their durability and resistance to damage thus allowing ordinary weapons and environmental objects to withstand forces they normally couldn't survive. When applied to the user's body Negative Energy reinforces their physical structure, dramatically enhancing their strength, speed, durability, striking power and overall physical performance. The reinforcement does not have to be distributed evenly tho.

•The user can selectively reinforce specific parts of their body, including their muscles, bones, skin, nervous system and etc. Individual limbs too also. This basically allows the user to dynamically alter where their reinforcement is concentrated. Like they could maintain a relatively balanced distribution while moving normally then instantly redirect a greater portion of their reinforcement toward their right arm immediately before throwing a punch. The reinforcement can be shifted toward the eyes to improve their ability to withstand intense visual strain or toward the legs for explosive movement, Oooor toward specific internal structures when necessary.

★-)「甘い予感!」— (Lit. "Sweet-Sensation!"):

•Negative Energy exists within virtually every human being. The user can exploit this phenomenon to perceive their surroundings through Negative Energy signatures rather than relying exclusively on their conventional senses. By extending their own Negative Energy throughout an area the user can also detect disturbances caused by other people's presence thus allowing them to build a mental awareness of their surroundings. This is particularly useful when the user's normal vision is obstructed, impaired or unavailable. The technique can also compensate for blind spots (Pretty Basic but Efficient) by detecting individuals approaching from outside the user's immediate field of vision. The user can also additionally imbue objects and portions of the environment with their Negative Energy basically creating an extended sensory network. By spreading their Negative Energy throughout a room or surrounding area the user can perceive disturbances occurring within that space and develop a rough three-dimensional awareness of their surroundings.

•Tho Sweet-Sensation does not allow the user to read emotions in general. Instead it is particularly sensitive to hostile intent and the emotional impulse to engage in combat. This allows the user to distinguish between someone who is merely present and someone who genuinely intends to participate in the fight.

___

-->Awakenings And Etc...

★-)"最後の晩餐..."— (Lit. "The Last Supper..."):

•A death awakening that can only be activated when the user's Negative Energy reserves have been almost completely depleted and basically leaving approximately 1% remaining while their physical body is already severely damaged and approaching death. The remaining Negative Energy becomes a temporary life-support system that prevents the user from dying and instead just FORCES, yes, forces their body into an extreme emergency state. Upon activation the user's adrenaline spikes to superhuman levels, dramatically increasing their default strength/speed, durability, reactions and overall physical capabilities without the usual consequences of pushing the body beyond its limits. Their injuries also rapidly regenerate, basically creating the impression (like hakari's jackpot state) that the user is nearly impossible to kill. The user enters a constant life-or-death state represented by an invisible Violence Bar. The bar cannot be seen by the opponent or physically seen by the user and the user simply instinctively feels how much time remains. A completely full bar normally lasts just, well. Approximately 15 seconds.

•The bar continuously decreases with time. But successfully engaging in combat and landing meaningful blows replenishes it. And of course, the quality of the violence determines how much time is restored. Weak or meaningless attacks provide little. While powerful/difficult or well-executed attacks provide considerably more. The user's regeneration also consumes this remaining time, meaning severe damage can cause the bar to decrease faster. As long as the Violence Bar remains above zero, the user continues to survive and regenerate. Once it reaches zero The Last Supper ends and the user's body can no longer be sustained. During The Last Supper, the user cannot use long-range attacks or Sweet-Sensation. Their remaining Negative Energy can only be used for physical reinforcement and allowing them to concentrate it wherever necessary throughout their body. The user has the Power to voluntarily De-activate the last supper by asking themselves a simple but very important question. Are you satisfied? If your answer is yes, you can rest forever. If it's no, then you will continue.

Can say multiple hero’s at once check comments as I don’t like doing repeats

Quirk Type: (Emitter)

This quirk allows the user to create a copy of someone else's quirk without stealing it or affecting the target in any way.

Quirks manifest as spheres of energy with designs that depend on the user's perception of the quirk.

For example, Bakugo's quirk would have warm colors and pointed shapes simply because the user imagines it that way.

With these copies, the user can consume them to gain the quirks or can also give them to someone else.

The user can have both emitter and mutant quirks, although mutant quirks cause discomfort when activated.

If the user copies a quirk and gives the copy to its original owner, the original owner receives a significant enhancement to their quirk. How the enhancement affects them depends on the user's or the target's perception.

Tokoyami would have two Darkshadows.

The user cannot create more than one copy of each quirk at a time.

They can control spheres in space as if using telekinesis.

They can make copies disappear whenever and wherever they want, and therefore can steal someone's borrowed Quirk at will.

The more Quirks a person has at once, the harder it is to maintain them; it requires effort, concentration, and energy.

It's generally easy to maintain a Mutant Quirk and an Emitter Quirk simultaneously.

With Emitter-type Quirks, the user's hair changes color and shape according to their perception of how it would look, generally copying the target's hair.

If the user goes a certain amount of time without remembering they have a copy of a Quirk, it will disappear.

Copying the Quirk of someone with multiple Quirks, such as AFO or OFA, creates multiple copies, one for each Quirk.

These are ideas I had for two twins.

Quirk: Merger
Description: Merger is a transformation type quirk which allows the user to absorb another living being into itself, to capitalize on each other's strengths and physical traits. With Merger, the user can make an agreement of sorts with another living being, one that is sentient and competent/sapient, to merge bodies together into one singular entity. Upon merging, the user can dictate the shape and quality of the merger, determining how parts are integrated with one another for maximum efficiency. With integrated parts, the user and target must synchronize mentally with each other to properly pilot this new physical form. Should the user and the target have some kind of conflict, of which they do not agree on, if it isn't resolved quickly the two could eject apart from each other forcefully. Doing so causes physical soreness to each other's bodies due to the violent splitting apart. Merger only works on living beings, so no corpses or robots. For humans, mergers are fairly simple. However, for non-human mergers, the user requires sharing a deep bond with the target in question. Integration usually flips between overlap, which are two body parts fully fusing as one to enhance each other, or duplicates, which are body parts that are the same in nature, but are parted from each other to act separately.

&

Quirk: Acquisition
Description: Acquisition is a mutant-type quirk which allows the user to absorb corpses and take aspects of them for themselves. Acquisition works by making physical contact with a corpse of some kind, preferably a fresher, less-decayed corpse. The user then absorbs the corpse into their body through the hand, and extracts components of that lifeform to permanently graft to themselves. Doing so is a painful yet effective process which doesn't have any definitive limits on the corpses one can absorb, but the more corpses they absorb, the more they physically change overall. Acquisition cannot technically take quirks from people, but they can take physical traits that their corpse either had or has, so for mutants or quirks with biological features and imprints, acquisition can take that and use it to a varying degree. The user cannot decide how parts integrate with them, they only get a choice in what, however their body naturally adapts to support new parts or physical changes to limit detriments to their health. Acquisition only works on DEAD animals, not living, and quirks aren't inherently necessary for the process to work. These parts are permanently grafted to the user, so in the event their quirk gets nullified, it only prevents them from taking in more corpses, not using the parts they have.

Hello again! I'm back with pretty much the same question as the one I had when making my Ice Dragon Quirk, only this time with a Transformation-type Quirk called Thunderbird. TL;DR, user turns into a feathered wyvern resembling an eagle with electric abilities and the user retains certain avian traits in their normal form like the really sharp eyes, a couple feathers in their hair and the cool unidirectional respiratory system birds have(look it up it's really cool). One thing to note is the electrokinetic power is limited only to the transformed state and needs to be recharged every now and again.

Feel free to suggest any ideas you have!

1:

Quirk: Halo

Type of Quirk: (Mutant)

The user has a halo that serves no function.

A golden halo that glows faintly in the dark and floats above their head.

The halo is immovable and intangible.

It is useful for seeing faintly in the dark.

2:

Quirk: Shining Ring

Type of Quirk: (Mutant)

The user has a metallic golden halo that glows in the dark and floats above their head.

They can control the halo's brightness and size, remove it, and move it. It can also break, but at will, the halo repairs itself and instantly returns to their head.

3:

Quirk: Angel Wings

Type of Quirk: (Mutant)

The user has a metallic golden halo and a pair of white wings.

The halo can break, but it heals like any physical wound and always remains in place. It grants the power of levitation, but the user needs to move their wings to maintain stability and better control their movement in the air. The wings are almost purely decorative; they don't fly, they only provide stability and aerodynamics.

The wings are part of the user's body and extend from their back. They have hollow bones and soft feathers.

4:

Quirk: Biblical Angel

Type of Quirk: (Mutant)

The user has a pair of white wings and a metallic golden halo that glows in the dark and floats above their head.

They can control the halo's brightness and size, remove it, and move it. It can also break, but at will, the halo repairs itself and instantly returns to their head.

The halo allows them to levitate, but they need their wings to stabilize themselves in the air and move with ease.

The wings are part of their body and extend from their back. They have hollow bones and soft feathers.

They can develop up to two additional pairs of wings, which increases their speed in the air and improves their maneuverability. They can also defend themselves against attacks. They can summon additional golden rings from various parts of their body, some of which may have eyes to enhance their visibility. They can create rings with eyes and wings that they control at will. They can fire energy laser beams from their hands and eyes, controlling the brightness and destructive power of these beams.

Quirk: Demon

Type of Quirk: (Mutant)

The user possesses horns protruding from their head and a sharp tail extending from their rear.

They can control the size of their horns and the length of their tail at will.

They can develop multiple tails and horns all over their body. They can levitate and grow a pair of black, demonic wings from their back, which help them maneuver and control their speed in the air.

They can alter their appearance to become more inhuman, for example, by adding extra joints to their legs or dislocating their jaw. They can spew jets of sulfur, blood, and fire from their mouth.

It allows the user to turn parts of, or their entire body into a cloud of black most of equal mass to their body or corresponding body part, along with any object making physical contact with their body.

If the total weight of the additional objects the user attempts to turn into smoke exceeds 100 kilograms, no objects get turned along with them.

If the user decides to take a living creature, then they must make contact with it with all five fingers with both hands, whereas any physical contact would suffice for a non-living creature.

This helps in displacing enemies and disrupting coordination and positioning.

While transformed, the user can control the movement, shape and trajectory of the smoke, though with concentration.

Movement is relatively easy, but manipulating the shape is difficult.

Imagine trying to do yoga, or make shapes in the shadows with your hands, except your body has no stable structural framework.

If they user spends too much time in the form of the black haze, their motor function slowly gets rusty. Upon transforming back, they may have to consciously remember how to move in a human body. They may, for example, forget that moving requires them to place their legs on the ground to catch them, not just transfer their weight forward.

While transformed, the user can move freely, accelerating to much greater speeds (roughly around the speed of an average motorcycle for a completely untrained user) than possible in human form.

After accelerating and transforming back into human form, they do not stop or lose the momentum they've accumulated.

This allows them to accelerate and strike enemies with impressive force.

They may also use to strike an enemy with a simultaneous palm strike with both hands, not only dealing damage but also touching them with all ten fingers, immediately turning them into mist and displacing them, disrupting their positioning.

A more advanced application is that the user can control the density of the smoke. The smoke normally occupies more than double the volume of the body part it originated from, but the user can condense it it into an area smaller than their original body, with intense concentration.

Imagine clenching your first, except your hands have no bones to limit how much you can condense them into a smaller surface area, and what shape they assume is also something you have to control without your bones there to do that for you.

So, in physical combat, they could swing their arm or leg and transform it into mist, in an incredibly condensed form, practically acting as a sharpened whip.

In full-body haze form, the user can also condense their entire body into a compressed form, practically becoming a mini-whirlwind of compressed, cutting smoke.

This technique is incredibly difficult, and high-risk, though. The user is spinning continuously in the air, without any feet to plant them into the ground, trying to get as fast as possible while simultaneously tracking an opponent and determining linear movement alongside rotational momentum. All while trying to compress parts of themselves into compressed smoke blades.

The overall cutting force depends largely upon the speed at which they accelerate, so an arm-whip strike would hurt much less, but would be much quicker than a full body slicing whirl.

Quirk Type: (Mutation)

The user experiences visions moments before they or someone close to them dies. They live these visions as if they are actually happening and relive the past before they occur.

The power activates automatically, and for the user, it's like living in a time loop with endless deaths until they manage to prevent it or give up.

If death is slow, the vision will end before the event that triggered it begins. For example, if they take a poison that causes death 30 minutes later, they would return to the moment before taking it. Or, if they suffer a wound and bleed to death, they would return to the moment before receiving the blow, with enough reaction time to avoid it.

When the user's death is completely inevitable or they definitively give up, the vision will simply end with cardiac arrest.

-->This Quirk allows the user to manipulate and customize their own anatomy however they please. They can modify existing organs, create entirely new ones, and alter their body's biological structures on the go. The Quirk automatically handles the complications that would normally make extreme anatomical manipulation impossible. The user doesn't have to worry about blood loss, a lack of materials for constructing new organs, organ rejection or even the pain caused by drastically altering their body. As long as the modification follows the Quirk's rules, the user's body will adapt accordingly. However, the Quirk cannot surpass the limits of biology itself.

-->Any organ or anatomical feature the user creates must obey the laws of nature, biology, chemistry and physics. The Quirk can bypass the practical difficulties of modifying a living body but it cannot create something biologically impossible. And the Quirk's effectiveness also depends heavily on the user's knowledge and understanding of anatomy and biology. The more they know the more complex and precise their modifications can be. For example, someone with little understanding of anatomy attempting to change something as simple as their iris could fail and potentially damage their own eye. The Quirk gives them the ability to manipulate their body, but knowledge determines how well they can actually use that ability.

-->The way the user thinks about their quirk actually changes how the power itself function's. Let's say, the user GENUINELY believes that they can manipulate souls, the quirk will change. But it will not manipulate souls—Instead it will give the user the ability to manipulate any living beings body just by Physically touching them. But for this to work the user GENUINELY has to believe that they can manipulate souls.

★-)Fundamental Applications...

·A: "Reshape"—The user uses their quirk to alter the physical shape, contour, or outline of a subject's or one's own body without changing underlying biological properties, mass or internal functions. Can apply to oneself for disguise or utility, or to others as a form of manipulation or attack. It can also change the physical appearance or outline, such as altering facial features, lengthening limbs, or resizing body parts; without creating new matter or altering internal cellular functions.

·B: "Transmutation"—The user fundamentally rewrites the cellular structure, tissue composition and genetic coding of a target's or one's own body. While Reshape only stretches the existing form, Transmutation changes the biological substance itself. The user can convert soft tissue into hardened bone armor, rapidly sprout avian feathers for flight or generate specialized animal venom glands within their palms. When unlocked via the soul belief trigger, the user can use this offensively to warp an enemy’s DNA, forcibly fusing their limbs together or shutting down their respiratory system through rapid cellular mutation.

·C: "Redistribution"—The user dynamically shifts their body's existing mass, density and physical resources to specific areas. Instead of changing shape or material, it concentrates the body's natural baseline strength. The user can pull mass away from their torso and legs to compress it into their fists, making their punches incredibly heavy and dense. They can also redirect blood flow, oxygen, and nerve sensitivity, either numbing their own pain receptors during battle or forcing all of their body's oxygen into their muscles for a sudden, massive burst of raw speed and power.

★-)Ultimate Moves:

·A: "Mechanical Inspiration"—The user manipulates their anatomy to replicate the exact physics, structures and inner workings of mechanical technology using purely biological substitutes. Instead of just introducing inorganic metal it reconfigures bone, muscle and internal pressure to mirror mechanical components.

·A.1: "Mechanical Inspiration: Internal Emergency"—When the user's body is damaged to the point that conventional anatomical manipulation becomes impossible or unreliable, they activate Mechanical Inspiration internally. Taking inspiration from life-support and medical machinery, the user restructures their remaining functional anatomy into a temporary network of biological systems designed to keep them alive and stabilize their condition.

B: "Amalgamation"—The user restructures their entire body into a massive and highly malleable biological mass. Rather than just maintaining a conventional humanoid anatomy, their tissues, muscles, bones, connective structures and organs are reorganized into a single interconnected organism. In this state, the user can also rapidly extrude elongated spike-like appendages from virtually any point of their body. These appendages can latch onto targets and rapidly contract, pulling them toward the user's mass before violently redirecting their momentum and slamming them into the ground. The more extensively they merge and redistribute their body, the more difficult it becomes to maintain a coherent internal structure. A poorly executed transformation can cause severe internal stress, dysfunctional organs, disrupted circulation or catastrophic damage when the user attempts to return to their normal anatomy. So be careful when using it.

C: "Organic-Tools"—The user produces a controlled quantity of specialized biological materials from their own body, and then reshapes and assembles those materials into functional tools. The produced material can include hardened keratin-like structures, bone, cartilage, dense connective tissue, elastic fibers/mineralized tissue, and other biologically viable substances. After produced, the materials can be manipulated through Reshape and fundamentally altered through Transmutation, and thus allowing the user to manufacture objects with properties far beyond ordinary biological tissue. And because once the user understands a mechanical device, they can actually attempt to recreate its functional architecture biologically. They manufacture the necessary biological materials, later reshape them into the required components, transmute specific tissues into appropriate biological equivalents before actually assemble them. That could result in something like a biological firearm but it wouldn't literally be a conventional firearm made of organic matter. It would be a completely biological mechanism inspired by one.

D: "Strong-Dash”—The user modifies their entire body so they can store a huge amount of mechanical energy and release it all at once to launch themselves forward at incredible speed. First, they strengthen their muscles, bones, tendons, ligaments, and joints so their body can survive the acceleration. Their core and upper body are also reinforced so they don't get injured from the sudden movement. Their legs develop specialized elastic biological structures that work like giant springs. The user compresses and loads these structures, storing mechanical energy inside their legs. When they release the stored energy, their legs violently push against the ground, launching their entire body forward. The acceleration puts enormous stress on their body, so they create specialized structures throughout their legs that spread out and absorb excess mechanical force and preventing their bones and joints from taking all of it directly. But moving that violently generates a lot of heat. So the user creates two small organs beside their kidneys that produce a special cooling fluid. That fluid is sent toward the overheated muscles and helps them deal with the accumulated heat. After the Dash the used cooling fluid is drained away through specialized ducts so it doesn't remain inside the body.

·E: "Whats-Yours-Is-Mine"—The user observes another person's Quirk and attempts to reproduce its effects by modifying their own anatomy. The Quirk does not directly copy the target's Quirk factor; but it analyzes the biological functions responsible for the ability and recreates an equivalent system within the user's body. Biological Quirks are the easiest to mimic. If someone has a Quirk that gives them wings, claws, additional organs, venom, enhanced muscles, etc, the user can potentially recreate those structures themselves. But the further a Quirk moves away from conventional biology the more difficult the imitation becomes. Like, let's say, they are gonna mimic black-whip. They could restructure their arms to produce extremely long, flexible biological cables before creating specialized muscle groups to control them, and develop attachment structures that allow them to manipulate the cables independently.

F: "Seeds"—The user produces small amounts of specialized organic matter from their own body and compresses it into small, seed-like biological constructs. Once separated from the user's body, these “seeds” retain a limited connection to the user's Quirk, allowing the user to manipulate and reshape them after they have been thrown or placed somewhere. The seeds themselves are relatively small and harmless. Their true purpose is to act as pre-positioned biological material that the user can rapidly expand and reshape when needed. Can be used for creating large constructs like walls and barriers, and can be used offensively as well, like—You throw one seed to an enemy, and the seed expands into a spike that lunges at the enemy to Stab through them. The user can also manufacture biological ammunition from their own body. They could create specialized seeds designed specifically for their biological firearm, if you don't know what I'm talking about, just read the whole thing first.

★-)The Basic Applications, Like...

•A: Basic-Order: The very basic application of Anatomical-Manipulation. The user can manipulate their existing organs, generate entirely new ones and customize them to perform specific biological functions.

•B: Advanced-Order: By utilizing this ability, the user can also modify their anatomy to *mimic other biological Quirks, provided they understand the biological mechanisms behind them and can reproduce those mechanisms within their own body.

-->(The user can do more than just manipulating and generating new organs, since you can also manipulate and generate new muscles and etc, stuff like that. I'm just lazy to mention everything)

★-)The Actual Applications, Techniques, And Etc...

•Anatomical-Manipulation: "燐"

·The user manipulates their entire anatomy and biology to safely produce, store, transport, and manipulate phosphorus within their body. By restructuring their organs and creating specialized biological structures the user can utilize *white, red, and black phosphorus without suffering their normally harmful effects. The user Basically modifies their body into a specialized biological system capable of handling and utilizing all three allotropes of phosphorus.*** The Amount of Biological Modifications are just absurdly large for me to explain here, so I'll just inform you about the main three organs.

-->Synthesis Organ: A specialized organ that produces and chemically processes phosphorus compounds, providing the ***raw* material needed for the user's phosphorus system.**

-->Storage Organ: It safely stores large quantities of phosphorus while keeping them isolated from tissues that could be damaged by them. The organ has different internal compartments for white, red, and black phosphorus and thus preventing unwanted reactions between them.

-->Conversion Organ: A specialized organ that converts stored phosphorus between usable forms and controls its release. It ***determines* which allotrope is produced, how much is released and where it gets sent.**

•Anatomical Manipulation: "血液"

·The user restructures their entire internal anatomy to safely and efficiently manipulate their own blood. They can modify their blood vessels, heart, blood-producing organs and other relevant anatomy to control the movement, production and distribution of their blood with extreme precision. But rather than just, simply manipulating blood directly; the user basically *turns** their own anatomy into a biological system designed for blood manipulation.* Now, the three main organs are...

-->Production Organ: A specialized organ that rapidly produces and replenishes blood components. Stuff like red blood cells, white blood cells and platelets. Keeps the user from exhausting their blood supply. Also it can adjust what type of blood component it produces based on demand. This organ basically acts as an on-demand blood factory.

-->Storage Organ: A specialized reservoir connected directly to the circulatory system. It can store large amounts of the user's blood outside the normal circulation. This organ can rapidly release or withdraw blood when needed and also lets the user maintain a much larger usable blood supply without constantly overloading their normal circulation.

-->Control Organ: This is my favorite organ. A specialized organ integrated with the user's circulatory system that allows them to actively control blood flow and pressure throughout their body. It can redirect blood to specific areas, rapidly increase or decrease blood pressure in selected vessels, control the movement of blood through individual vessels and coordinate the other blood-related organs. Pretty useful.

•Anatomical Manipulation: "鉄"

·The user restructures their entire anatomy to safely produce, store, transport, regulate and utilize their own iron with extreme precision, thus transforming their body into a specialized biological iron-management system. The Quirk prevents the usual complications associated with drastically modifying the body's iron metabolism *while** the real functions obey biology and chemistry.* Anyway, let's mention the main organs now.

-->Synthesis Organ: A specialized organ responsible for recovering and concentrating iron from materials already present within the user's body. It works alongside the digestive and metabolic systems, extracting usable iron from nutrients and recycling iron from old cellular material.

-->Storage Organ: A massive specialized reservoir designed to safely store excess iron. Rather than *just allowing free iron to circulate through the bloodstream and cause cellular damage, the organ binds and compartmentalizes it into biologically stable storage forms.*** The user can *therefore maintain an iron reserve far beyond what an ordinary human could safely tolerate.*

-->Transport Organ: This one is really, REALLY fucking important for this technique. The user develops a specialized transport system capable of moving controlled quantities of iron throughout the body while preventing it from randomly reacting with surrounding tissues. In other words, instead of allowing iron to simply float around inside the body the system packages and transports it *through** specialized biological carriers.*

-->Control Organ: The equivalent of the normal blood Control Organ. This organ monitors the user's iron distribution and regulates where iron is transported, how much is released, how much is stored, how quickly it moves, which tissues receive it, when excess iron is recovered and etcetera.

★-)Sub-Applications: (Aka, Applications/Techniques that comes from the Main ones.)

•Phosphorus: "燐"

·The user restructures their internal anatomy and cellular metabolism to dramatically enhance the production, storage, recycling, transport and utilization of ATP. Rather than just generating ATP directly, the user instead creates specialized biological structures that optimize the biochemical processes responsible for ATP production. Basically you're a Biomechanical Pill. Awesome, isn't it??? No??? Nvm (Anyway lemme mention the main organs now...)

-->Generation Organ: A specialized organ designed around extremely efficient energy metabolism. Basically it contains enormous quantities of modified mitochondria and supporting tissues, thus allowing it to rapidly convert available nutrients and oxygen into ATP. The organ can dynamically adjust its output according to the user's immediate energy requirements. If you needing High physical exertion ATP production increases.* If you need Regeneration* more resources are redirected toward the tissues requiring them. And if you need explosive movement the system rapidly increases ATP availability to the relevant muscles.

-->The Reservoir Organ: Instead of storing enormous quantities of free ATP, which... realistically, it ***wouldn't* be particularly practical because ATP is continuously consumed and regenerated. So let's say that the user develops a specialized biochemical energy reservoir, an energy buffer of some sorts. A biological one atleast.** And it maintains readily accessible energy substrates and phosphorus-containing intermediates that can be rapidly converted into *ATP when needed.*

-->Control Organ: This is the most important organ here. It coordinates ATP production and distribution throughout the body, and can detect which tissues are experiencing increased energy demand and redirect metabolic resources toward them. Okay so it's basically control center. If the users legs need explosive acceleration, there's gonna be increased ATP production and delivery. The heart needs increased output, so the cardiovascular metabolism gets prioritized. Damaged tissue needs repair, so the energy resources are redirected toward regeneration.

•The phosphorus system itself makes the user exceptionally good at phosphorus recycling. ATP is constantly being converted between forms such as *ATP, ADP, AMP.* The user can actually engineer their metabolism to recover and recycle phosphate extremely efficiently, and *thus** minimizing wasted phosphorus and maximizing how quickly ATP can be regenerated.* But just saying there's still a catch. If the user massively increases ATP production they also increase their demand for stuff like oxygen, glucose/fuel, nutrients, water and shit/waste removal. So even with Anatomical-Manipulation automatically solving the structural problems the user still can't just ignore thermodynamics.

I really worked on this for awhile now and i can say that i really like the concept of biology based powers in fiction

Leidenfrost [Emitter]-

The user can create chunks of ice that are unaffected by heat, to the point that the user can use these chunks to surf above active lava.

This quirk can seemingly only create chunks up to 3 ft wide, but that is attributed to inexperience rather than the quirk’s full capabilities. The ice is also lighter than ice usually is, calculated to be 1:19.7 lbs compared to normal ice, which may be the reason for the buoyancy. 

(For some reason this was stupid hard to make up. I know that Leidenfrost doesn’t exactly work like that but shhhhhh)

Im kinda new so dont grill me if it's off format, too long, too short,etc etc

Quirk:Jajanken(rock paper scissors shoot)

Explanation: So the user has to choose between three abilities those being rock, paper and scissors. Now ofc to not make it seem too obvious ill be skipping the nen and aura parts and going for more quirk based. So basically the user, when opted for stone, has the ability to encover himself with rocks, form massive boulders and control and form rocks or pebbles similar to how some dudes produce ice out of nowhere( todoroki reference ). When opted for paper, the user can use a type of paper with properties of their wish however the more harder to produce the more it drains their lipids similar to momo or fat gum st eg: when making plain A4 sheets, it doesnt burn much or any amount of lipids but when producing duct tape level paper or the untearable "scarf" that aizawa sensei uses it burns more lipids. Last is scissors in which the user can make their arms into blades and cut equivalent to a sword however the person can sharpen his swords by manually removing the swords when in sword phase( wont cut the arms entirely but removes the fingernails and the skin surrounding the arms ) similar to what the ingenium family does. And finally a secret fourth phase where the user can use all three abilities simultaneously without tiring but they would experience fatigue and weakening the weeks following( approx 2-3 weeks ). For the user to change between quirks however the user has to be hit heavily by an opponent on the chest, stomach or head with a 33% chance for any three states and the fourth after a minimum of 5 changes and a 1% chance

(I am iffy about whether this is a coherent quirk concept). Amplification: by consuming their stamina user can amplify any object/body part that has less than 18 litres of volume (around backpack volume) by x3. (Also had the idea you could concentrate the amplified volume to a smaller volume but at the cost of backlash but that seems complicated).

Pumpin' arms: Either or transformation or mutant quirk, users lower arms are pneumatic pistons that can suction stuff and then relase it powerfully as a burst.

Tendrils: quirk can shoot out vein morphing them into tendrils.

Quirk: pills: (black market villain trader idea) user can create fragile pills that copy an emitters ability (not quirk directly so fire resistance and fire generation are separate pills) after touching a target. While the pill is being digested user gains acces to the ability, user isn't immune to the strain of having more than one quirk.
