Killer Queen (キラークイーン Kirā Kuīn) is the Stand of Yoshikage Kira, featured in the eighth part of the JoJo's Bizarre Adventure series, JoJolion. Just like its original version, it is a humanoid Stand with cat-like features. It also can make objects explode and conjure bombs on treads.
Killer Queen is a humanoid Stand of similar appearance to its alternate counterpart. Its crown is flat, while two sharp, triangular shapes resembling a cat's ears stand on either side of the top of its head. Its eyes have cat-like vertical pupils in front of generally light-colored sclera. It has no nose. With thin lips, its mouth is perpetually closed.
It wears dark, studded, leather-like forearm-length gloves, mirrored in style by a garter belt-like band at its waist and ankle-height footwear. Its thumbs are additionally bandaged in white.
Its shoulders, the back of its hands, belt buckle, both sides of its ankles and the top of its feet all bear the emblem of a skull with ears resembling its own; in varying sizes and external decoration. One minor yet constant difference between the designs of Killer Queen and its Part 4 counterpart is that, while Part 4 Killer Queen bears two skull emblems at its belt buckle, Part 8 Killer Queen bears only one.
(Sheer Heart Attack)
Not much is shown of Killer Queen's capabilities, but like its counterpart, it is a close range Stand which always stays close to its user Yoshikage and has above average fighting abilities.
Moreover it possesses power revolving around explosives and can deploy two types of bombs to fight, making it a powerful force in battle.
These bubbles were described as floating in the air as projectiles, but are shown to also form inside a person's skin or an object if Killer Queen physically strikes them, having the target locally inflate and explode. The bubbles can presumably come from Kira’s hand.
