Gloom first appeared in the original Pokémon games of the 1990s as the middle evolution of Oddish, and it later became a familiar face in the long-running Pokémon anime. Its in-game cry has been carried forward across generations of games, so longtime players recognise it instantly even without seeing the Pokémon on screen. Online, the short clip circulates mainly among Pokémon fans, who reuse it in edits, reaction videos and soundboards as a shorthand for a droopy, unimpressed mood. That combination of nostalgia and a very specific character keeps it in use.
