Zalgo/Video Games

Luna Game series
Though not explicitly mentioned in-game, Zalgo-corrupted versions of My Little Pony: Friendship is Magic characters appear repeatedly throughout the Creepypasta inspired Luna Game series. The game originated from a series of anonymous uploads to the My Little Pony fan website Equestria Daily, which linked to downloads for disturbing platforming games involving the Pony characters, as the landscape became increasingly corrupted and the player is eventually jumpscared by Zalgo-corrupted versions of the Ponies.

Reimagine :the game:
Though again never explicitly mentioned or named in-game, Zalgo appears as a form of corruption in the comedic parody game Reimagine :the game:. A character known as simply The Boss appears in the game, serving as a minor character, committing minor crimes. However, as the game progresses, the Boss is increasingly corrupted and deformed in a Zalgo-like manner, eventually transforming into a frightening black mass of eyes and tentacles that serves as the main antagonist and final boss of the game, and must be battled by the player by taking control of several pop culture icons to set off a bomb that kills the Boss, but destroys Earth in the process.
