Step one: rework a beloved character in a way that takes their most iconic features, then warps and twists it into a horrific uncanny valley monster.

Teddy Bear after Mercy Treatment Step One:
Step 2: Lock all dissenters into a chasm of lost souls, sentencing them to go mad from the endless echoes of screaming agony, while their god turns a blind eye to their pleas for clemency. Delete any evidence they ever existed in public, and burn anyone who tries to escape at the stake.
Step 3: Be forced to stand by and watch as the community cheerfully dehumanizes you for liking a video game character. No matter how many essays you write, no matter how many graphs and stats you provide, anything you say while you campaign for your hero to be fixed is dismissed as a garbage spewed by a (insert slur here) stepping out of line.
Step 4: Watch the monstrosity that you hero has become agonizingly slowly be hollowed out, with nerf after nerf that never addresses the real problems with the character. You plead with the devs to get it over with and fix this by reversing course, but the result is the same. They ignore your pleas, and continue to mummify a mangled mess with the face or your hero grotesquely glued on.
Step 5: The hero you loved is gone. The community hates you for existing. The devs blithely make statements about how they’ve done a marvelous job at “fixing” your hero, when all they’ve ever done is make the problem worse.
