Killer Queen

Killer Queen (キラークイーン) is a stand featured in Part IV: Diamond is Unbreakable.

Appearance/Personality
Killer Queen is a humanoid stand with fox-skull emblems on its shoulders, waist, and knees, and a vaguely cat-like head. Also, the space behind its stomach is hollow, letting it contain small items or creatures there.

Bomb Creation
Killer Queen's abilities mostly involve explosions. Its primary bombs are actually booby traps, it touches a cohesive object (doorknobs, coins, even living bodies) and charges it. When someone touches it, the energy will be conducted into it, creating an internal explosion that completely disintegrates the target. On occasion, he will charge an object not to conduct explosive energy, but simply to explode when he finds the time to be right. By carrying Stray Cat in an opening in its stomach, it can utilize its control over air and produce invisible air bombs. Although even Kira can not see the bomb, he is skilled in determining its trajectory using basic mathematical skills.



Sheer Heart Attack
This secondary bomb is normally contained within Killer Queen's left hand. It is a completely autonomous bomb with unlimited range, looking like a tank-treaded ball with a fox-skull face. Its method is to seek out whatever the warmest thing in the vicinity is, then induce an explosion there, with a power proportional to the heat of the target. Also, Sheer Heart Attack is totally indestructible, having withstood countless blows from Jotaro's Star Platinum without a scratch.

Bite the Dust
''Note: In the Manga, the storyline featuring this ability is called "Another One Bites the Dust". The Ability itself, however, is merely called "Bite the Dust", written in Rômaji (Western Letters), in the japanese version.''

Late in the story, his father Yoshihiro Kira's stand creating Arrow pierces Kira's body a second time and grants Killer Queen a tertiary bomb. This bomb is actually a distinct, miniaturized form of Killer Queen, which normally stays with someone who knows Kira's secrets – most notably Hayato. If someone tries to interrogate that person about Kira, the tertiary bomb will enter their field of vision, get into their eye that way, and induce an explosion. Until Kira finds out who the bomb killed, he lets a brief temporal loop occur to one hour or day earlier. Even if the victim doesn't ask questions this time around, Bite the Dust will still kill them. Only if Kira is confident about who died will he let time flow normally. Still, if he has to protect himself right away (he can't maintain more than one potential bomb at a time), he will dispel the bomb. In all three cases, internal explosions can potentially completely disintegrate the victim.

Hayato has added that Bite the Dust only works on non-stand users, such that Kira can only tell a non-stand user his secrets to enable the ability.
