Klavier Gavin is the rock-star prosecutor of Apollo Justice: Ace Attorney (2007), the fourth mainline Ace Attorney game, where he fronts the in-universe band The Gavinners and treats cross-examinations like concert sets. His animated air guitar riff became one of the fandom's favorite reaction moments, clipped and reposted across meme edits whenever a scene needs instant rock-star swagger. Years later the bit still circulates because it distills Klavier's whole persona — glamorous, cocky, theatrical — into a single strut, making it a go-to shorthand for overconfident entrances online.
