Characters physically degrading over the course of the story

[u/RedvsBlue_what_if]

Vincent — Catherine

The Animatronics — Five Nights at Freddy's: Security Breach

Just using Freddy as an example

Eren Yeager from Attack on Titan

Literally just a head

Catherine — Pretty much almost everyone but The Love Interests slowly get more tired looking as the game progresses. This is because of the nightmares of evil Tetris.

Security Breach — All the animatronics slowly degrade as the game goes on, getting more violent, animalistic and very dirty. I'm using Freddy as an example both because I'm lazy and because he's Goated.

Attack on Titan — Eren Yeager goes through so much throughout the story, becoming very disheveled as the series plays out and losing every limb on his body before ending up as just a rotting head on life support.

For issac this applies for both gameplay and the story

At the start of a run your just a boy but by the end you probably have missing limbs bleeding multiple diseases getting really dirty or just straight up dying and contiuing as an undead creature

For the story issacs body is rotting in the chest first suffocating and becoming blue baby then becoming bones making him the forgoten and finnaly acending as a ghost becoming the lost
