Killer Queen is a Stand with the ability to turn things it touches into bombs. It can fight up close with powerful punches and has several unique abilities that make it dangerous to go against.

First Bomb: Turns something Killer Queen touches into a bomb that can be detonated remotely.

Second Bomb: Sheer Heart Attack: Sends out an automatic bomb that chases its targets and explodes.

Third Bomb: Bites the Dust: Rewinds time to an earlier point, undoing what happened while allowing certain memories to remain.

Barrage: Unleashes a rapid series of punches against an enemy.

Heavy Strike: Delivers one powerful punch that deals 2d20 force damage on a hit.

Killer Queen's abilities are controlled through the actions listed in this feat. Any effects that D&D Beyond can't handle automatically, such as remote detonations or rewinding time, are decided by the DM.
