Cue stick (equipped with mechanism enabling it to magnify any force applied to it more than a thousandfold and transmit that force to anything it strikes), ball-bombs (pool balls containing explosives which detonate on impact).
The A-Bomb was found inside the Headman's brain and defeated by Little Monster. This incarnation of A-Bomb is a warp between A-Bomb (Rick Jones) and the Abomination. Search this site for: A-Bomb ยท A-Bomb (Warp World) (Earth-616).
