A-Bomb is Hulk's very best friend and an enthusiastic S.M.A.S.H. teamate. He is also the alter ego of Rick Jones.

Rick Jones's alternate identity, A-Bomb, was created when Rick stole Red's Sandblaster in an attempt to help Hulk stop an invasion by Annihilus. He accidentally overloaded the vehicle's gamma core and the resulting explosion transformed him into a blue gamma powered hulk.

He is now one of the Agents of S.M.A.S.H. helping Hulk battle evil in a smashing way.
