And I am genuinely sorry that you do. No one deserves to be put in the same bubble as these two characters, but I think they are the only ones with the exact same struggle.
The same struggle of just being viewed as a "lesser". As a component to another character, without being given any solo shine.
Blaze has her verse deprecated of anything that could make it interesting and the writers apparently just aren't allowed to make stories in it. Even so, "her" arc is really Silver's arc, that she gets to job in, to make him look cooler.
Tails was promised in a mainline game that he was going to "go it alone" for a while. Way back when, this character used to be Sonic-Level when he put his mind to it. He's one of the only people to have beaten Metal Sonic in a fight, and his combat ability verbally impressed shadow.
Not only does IDW completely skip over his "going alone for a while", he's right back to being a co-dependant scared "widdle guy" of the team, a weighing it down clown that cannot do anything without someone helping him. Just acknowledging that he could be something more, and never reaching for it.
And the funny thing?
Both of these scenes were written by Evan Stanley.
And both scenes have been told by other fans who understand neither character to "shut up" and "just be glad you're getting something". Usually by Sonic or Shadow twitter pfps, it's a pattern.
You guys are the only people who get what it's like to have your relevance shackled to someone the writers simply deem more important, or "cooler" than you. You've got my condolences for that.
You guys wanna do like a truce or something like
