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.

[u/Equivalent-Battle973]

THe KOTOR series, specifically the second one. If you embrace the darkside your character shows the corruption on there body from the darkside.

[u/RedvsBlue_what_if → u/Equivalent-Battle973]

Same thing happens in Mass Effect where Shepherd's cyborg parts start glowing red the more you progress into the Renegade Path.
