Killer Queen

Standing roughly as tall as Kira and built with visible muscle, this Stand carries a pale, usually pink coloring, a flattened crown flanked by pointed feline ears, and slit-pupiled eyes set in a noseless, tight-lipped face. Studded gloves, a belt band, and low footwear complete the look, while skull emblems bearing its own ear shape mark its shoulders, hands, buckle, and feet. A tiny red trigger sits on one index finger, and its belly is later revealed to be hollow enough to hide an object.

Unlike most humanoid Stands, its expression almost never mirrors its master, staying locked in a flat, wide-eyed stare apart from rare moments of fear or spite. Kira can speak through it, and its detachable sub-weapon voices short phrases of its own.

In melee it is fast and forceful, yet Kira leans on its powers rather than trading blows with heavier hitters like Crazy Diamond or Star Platinum. Its core trick charges any object, living or not, into a bomb at a touch; once a target makes contact, Kira presses the trigger on his finger to set it off. Anyone detonated is incinerated down to the atom, clothes and belongings included, which suits a killer desperate to hide his crimes. He controls the blast size and even which parts of a body vanish, often sparing a victim's right hand to keep. The power stalls without air, cannot fire if he can't press the trigger, and charges only one object at a time.

His second weapon, Sheer Heart Attack, is a treaded, near-indestructible sphere that detaches from the left hand and hunts the warmest thing nearby on its own, exploding on whatever it reaches. Its autonomy is also its flaw, since it chases heat rather than the intended person. Late in the story Kira slots the Stand Stray Cat into the hollow abdomen to launch invisible air bombs as projectiles.

The final and deadliest form, Bites the Dust, arrives after a second Arrow strike. A shrunken copy hides inside a chosen host and kills anyone who learns Kira's true identity by entering their eye and bursting. After a kill it rewinds time by roughly an hour, and only the host remembers each loop, with events fated to repeat. Killing Kira or forcing him to withdraw it erases every timeline it made.

Yoshikage Kira, a Morioh salaryman who murders to satisfy a fixation on women's hands, is the primary wielder throughout Part 4. After assuming the stolen identity and body of Kosaku Kawajiri, he keeps using it under that name, and it is in this guise that a fresh Arrow wound grants him Bites the Dust. In the light novel JORGE JOESTAR, Ultimate Kars later rips the Stand from Kira and wields it himself.
