So we have Killer Queen's primary bomb and Sheer Heart Attack in the alternate universe. Both Killer Queens' are similar to each other, but not exact carbon copies. For example, Kira's bomb is silent, while Kira's bomb is loud. Kira has one heat-seeking bomb that talks, while Kira has many small heat-seeking bombs that talk. Kira has a time reversal ability to beat an 11-year old, Kira.. doesn't. I'm fixing that.

Killer Queen: Bites The Dust (AU)

Killer Queen: Bites The Dust is the tertiary bomb of Killer Queen. After making himself a bomb, Kira blows himself up. Time goes back an hour, and Kira will blow up if he can't get Killer Queen to plant a bomb on someone else. At the end of the hour, the person who has the bomb planted on them silently vaporizes, like the old Killer Queen.
