Killer Queen is the Stand of Yoshikage Kira in JoJo's Bizarre Adventure: Diamond Is Unbreakable, first appearing in the 1990s manga before the later anime adaptation brought its reveal to a wider audience. Fans ripped the short reveal sting for soundboards and edits, where it became shorthand for a calm villain suddenly becoming dangerous. It sits alongside other JoJo staples such as Za Warudo and Giorno's Theme in fan edits, and it endures because the reveal is so closely tied to Kira's quiet, unsettling presence.
