Killer Queen (キラークイーン, Kirā Kuīn) Is a physically powerful short-ranged Stand of above-average speed and melee attacking power. Its attacks revolve around setting up bombs that can annihilate the Stand User’s enemies in one blast, able to set up multiple bombs with different strengths that activate with the imitating action of pressing down on a handheld detonator.

Alongside this, it also has the automatic bomb Sheer Heart Attack (シアーハートアタック, Shiā Hāto Atakku), using it for its greater range.
