Quirrel is a wandering knight in Hollow Knight, the 2017 indie adventure game by Team Cherry, known for his cheerful curiosity and his nail. His repeated battle cry has become a small fan favourite, shared on soundboards and clipped into gameplay videos, boss montages and Hollow Knight edits. Because the line is short, rhythmic and instantly recognisable to players, it works as a quick audio cue for courage, excitement or comic bravado. It remains popular with fans revisiting Hallownest and creators making new tributes to the game.
