Killer Queen is the Stand of villain Yoshikage Kira, introduced in Diamond is Unbreakable, the fourth part of JoJo's Bizarre Adventure created by Hirohiko Araki. Its primary ability, often called the first bomb, lets Kira charge objects and detonate them remotely, a power central to his quiet serial killer storyline. Clips of the activation sound spread through anime edits, soundboards, and meme videos alongside other iconic explosion lines like bomb has been planted, because fans instantly recognise the threat hidden in such a short, clean blast.
