Killer Queen

Killer Queen (キラー・クイーン) is the Stand of Yoshikage Kira, featured in Part IV: Diamond is Unbreakable.

Appearance
Killer Queen is a humanoid Stand of a height and build similar to Kira's, or slightly more muscular; light in color overall.

Its crown is flat, while two sharp, triangular shapes resembling a cat's ears stand either side of the top of its head. Its eyes comprise cat-like vertical pupils in front of generally light-colored sclera. It has no nose. With thin lips, its mouth is perpetually closed.

Its 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. Four short spikes line the top of its back.

Its shoulders, the back of its hands, belt buckle, a plate hanging in front of its crotch, 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.

Later, the space behind its stomach is revealed to be hollow and suitable for storing an object.

Personality
Killer Queen's semi-autonomous secondary bomb, Sheer Heart Attack, speaks phrases to its targets including "Look this way".

Kira is able to speak through Killer Queen, as he does to Rohan while using Bites the Dust.

Killer Queen shows no other evidence of consciousness.

Abilities
Killer Queen is a short-range humanoid Stand of average to above-average speed and melee attacking power. Its unique ability involves planting or targeting up to three kinds of bombs, usually capable of completely consuming their targets; though their explosions are neither normally harmful to more than one target, nor perceptible to non-Stand users. The main drawback is that only one bomb can be active (and only from one of the following bomb types).

Primary Bomb (Bomb Transmutation)
By touch, Killer Queen may charge any object as a bomb. If a charged object is touched, the charge travels from that object into the whole of a target before exploding and (usually) destroying it completely. Kira may also detonate this bomb at any previous point. However, only one bomb can be maintained at any given time.

Secondary Bomb ("Sheer Heart Attack")
Sheer Heart Attack (シアーハートアタック) is Killer Queen's second type of bomb, featured primarily in the arc Sheer Heart Attack.

In appearance, it is as a sphere, plated, with a superficial, removable knob on its top; standing on the treads of a tank at its sides; embedded in front by a cat-skull similar to those appearing on Killer Queen's body, with the addition of a downward dagger on the forehead, an articulate jaw, and a short spike as a nose.

This bomb detaches from Killer Queen's left hand, of which it is part. It is completely autonomous, with an unlimited range. It seeks out whatever the warmest thing in the vicinity is, then induces an explosion there, with a power proportional to the heat of the target. The body of Sheer Heart Attack is totally indestructible (withstanding countless blows from Jotaro's Star Platinum). As an autonomous fighter, it has no special weaknesses. As part of Killer Queen's hand, any external effects ascribed to it are transferred to Kira's hand.

Tertiary Bomb ("Killer Queen Bites the Dust")
Killer Queen Bites the Dust (キラー・クイーン バイツァ・ダスト), more simply known as just "Bite the Dust" (バイツァ・ダスト (負けて死ね)), is Killer Queen's third type of bomb; featured in primarily in the late arc Another One Bites the Dust.

Kira is granted this ability when Yoshihiro Kira's Stand-creating Arrow pierces him a second time.

This bomb appears as a miniaturized form of Killer Queen. In the only example shown, it is planted on Hayato Kawajiri. When someone interrogates Hayato about Kira, the bomb enters their field of vision, along with their eye; before inducing an all-consuming internal explosion.

Secondly, until Kira finds out who the bomb killed, he lets a temporal loop occur; from one hour to day earlier. Even if the victim doesn't interrogate Hayato on this occasion, Bite the Dust will still kill them at the time recorded before. Only when Kira is confident about who died will he let time flow normally.

It is possible that Bites the Dust has some precognitive powers, as when Rohan used his Heaven's Door in Hayato he saw things that had not yet occurred. Though it is also possible (and more probable) that Hayato had experienced the day once before already and thus it was written in his memories.

If Kira wishes to use Killer Queen, since he cannot maintain more than one potential bomb at a time, he must recall Bites the Dust. Hayato discovers that Bites the Dust only works on non-Stand users, such that Kira can only tell a non-Stand user his secrets to enable the ability.

Primary Bomb & Stray Cat

Finally, Kira carries Stray Cat in an opening in the stomach of Killer Queen. With Killer Queen's Primary Bomb, charging Stray Cat's condensed air bubbles, Kira may create invisible, speedy projectile air bubble bombs. Although he cannot see these bombs, he is skilled in determining their trajectory using basic mathematical skills.

Other Appearances
This section includes spoilers for Part VIII.

In Part VIII: JoJolion, Yoshikage Kira (JoJolion) is revealed to possess an unnamed Stand of an identical appearance and similar abilities to Killer Queen.

This Stand creates bubbles similar to those generated by Josuke Higashikata (JoJolion) with Soft & Wet, which explode on contact with their target (in an apparent reference to the combined ability of Killer Queen and Stray Cat).

Trivia

 * This Stand's abilities appear to draw inspiration from lyrics to the song Killer Queen – "She's a Killer Queen / Gunpowder, gelatine / Dynamite with a laser beam / Guaranteed to blow your mind / Anytime". Additionally, its appearance may be another reference – "Playful as a pussy cat".


 * This Stand's name and those of its abilities are based on three songs by Queen: Killer Queen, Sheer Heart Attack (also an album) and Another One Bites the Dust.


 * Araki includes Killer Queen's whole design among his favorite things to draw.


 * According to JOJOVELLER, the sword on Sheer Heart Attack's skull might be a representation of its victims.


 * In JoJo 6251, Killer Queen is the only Stand whose abilities are given separate stats as if they were Stands themselves.


 * Killer Queen has also been shown to appear at the call of its user even after death; whether this is a feature unique to Killer Queen or a quality that all Stands share is unknown.


 * Despite the fact that Sheer Heart Attack operates automatically, when Echoes Act 3 uses his Freeze ability to increase its weight, the effect reflects on Kira's own left hand. This is because SHA is a sub-ability of Killer Queen, which is not an automatic Stand.


 * Ability-wise, Killer Queen may be viewed as the opposite of Crazy Diamond; capable of disintegrating objects and people, while Crazy Diamond is capable of restoring them.


 * Bites the Dust's power might be inspired by the movie, Groundhog Day, where main character Phil Connors is stuck in time loop and lives the same day over and over again up until he changes his ways.


 * In All-Star Battle, Killer Queen's Bites the Dust ability will reverse many effects. As examples; Pucci's Made in Heaven may be reverted to Whitesnake, also reverting the timer back to its proper speed, the stage background to normal and clearing any words already said to Green Baby; Kars' Ultimate form and Giorno's Gold Experience Requiem will revert to their previous forms; Johnny's Tusk will revert back to Act 1 if its transformed into Acts 2, 3 or 4; and if Jonathan Joestar or Funny Valentine disable their HH gauges from using their special healing or comeback moves successfully, Bites the Dust will restore their HH gauges.
