Axie Infinity is a blockchain-based game developed by Sky Mavis, released in 2018, where players collect, breed, and battle creatures called Axies. Each Axie has unique body parts and cards that determine its attacks in three-versus-three battles. The game became widely known during the play-to-earn boom around 2021, and its battle audio, with creature calls and hit effects packed into short turns, spread beyond gameplay into streams, edits, and soundboards. Players still share the clip as an instantly recognizable cue for an Axie match starting.
