Boom Boom (Marvel Comics)

Tabitha Smith is a mutant who originally had the unusually strong ability to create variably-sized yellow orbs and spheres of pure plasma, fiery-like energy, which she calls her "time bombs". These "time bombs" explode with concussive force. She can produce marble-sized energized "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 are able to destroy durable objects including a Predator X, and a futuristic Nimrod.
