Killer Queen

Stand of Kira Yoshikage

Killer queens main body is a close range stand, also has a second bomb called "sheer heart attack" that is connected to their left hand.

Killer queen also keeps Stray Cat in its empty stomach cavity, and is able to use its powers with theirs in tandem when Kira gets hit with the stand arrow again and gains a proto "requiem stand" with the ability to attach itself to other people and create temporal loops.
