Ash comes from Brawl Stars, Supercell's mobile multiplayer shooter, where he is a small knight living in a trash can who builds Rage as he fights. Like other brawlers, he has short voice clips that play when he attacks, wins, loses, and gets hurt in a match. Players ripped and shared those hurt grunts on soundboards and in short video edits, where the clip broke away from the game itself. It is now used as a general damage reaction for any character taking a funny hit online.
