Deadly Queen

Killer Queen (キラークイーン 'Kirā Kuīn') is the Stand of Yoshikage Kira, featured in Diamond is Unbreakable.

Killer Queen is a short-range humanoid Stand of average to above-average speed and melee attacking power.[11] Although undeniably powerful physically speaking, it is overshadowed by other close range Stands like Crazy Diamond and Star Platinum and thus Kira relies more on evading his enemies or using Killer Queen's set of power to prevail.

Killer Queen's powers revolve around setting up different kinds of bombs that can annihilate Kira's enemies in one blast, making it a very dangerous Stand to face. Not only are the bombs powerful, Kira is able to deploy two initially, then eventually three kinds of bombs with different strengths, giving the serial-killer a large array of options when dealing with his foes.
