Killer Queen

Killer Queen (キラークイーン) is a stand featured in Part IV: Diamond is Unbreakable. The user is Yoshikage Kira, the main antagonist of Part IV, and its name and abilities are based on the three songs by Queen, Killer Queen , Sheer Heart Attack (also an album), and Another One Bites The Dust. 

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.

Abilities
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. 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.

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. Also, Sheer Heart Attack is totally indestructible, having withstood countless blows from Jotaro's Star Platinum without a scratch.

Another One Bites The Dust: Late in the story, his father Yoshihiro Kira's Arrow pierces a second time Kira's body 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. 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, Another One Bites 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.
