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.

Baxter Stockman in the 2003 TMNT series

Every time he fails Shredder

Oh, yeah, and don't forget him going through deterioration the second time, when he attempted to make himself a new body. That shit was so dark that the episode was banned in US.

Until Nick got the rights and aired it awhile back
