Powers: Boom Boom can create balls of energy of an unknown kind, which she calls her "time bombs." These "bombs" explode with concussive force. She can produce marble-sized "bombs" which have little concussive impact and which she uses for playing pranks. She has produced "time bombs" ranging up to the size of beach balls, which, when they explode, can smash tree trunks and even metal objects. To at least some extent Boom Boom can control the amount of time between the creation of one of her "bombs" and the time it detonates. She can also mentally muffle the sound of the detonation to a limited extent. The limits on her power to create and control her "time bombs" are as yet unknown.

Weapons: None
