she was part of X-force
has the mutant power to 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. Meltdown can control the amount of time between the creation of one of her "bombs" and the time it detonates. She can mentally muffle the sound of the detonation. She can also fire beams of concussive force.
