Tony's Reigonian Armcannon

Tony Smith possessed a special arm cannon created by his late mentor, the Autonomous Smith. The cannon was capable of launching a pressurized, and occasionally electrified harpoon into enemies. Tony could then retract the harpoon just by thinking.

The harpoon launcher proved useful as a trap, a grappling hook, a ranged weapon, a close quarters weapon, and practically any other thing Tony could think of.
