X-Force, Mutant Genesis: Boom Boom
Tabitha Smith was a member of the New Mutants, a group of young mutants Professor X brought together to teach them about their powers. Boom Boom could create "time bombs" and discharge them from her person. Since her days as a New Mutant, this feisty peroxide blonde has joined X-Force and honed her powers to the point where her "time bombs" can be of any size, intensity or detonation time.
