Thunder Man (John 23: Megaman)
Thunder Man is the version of AmpFibian that appears in Dimension 23, used by Megaman. His chest is encased in the Mega-Tech Armor, and the Mega Buster is on his lower left arm. The Mega Buster is too heavy for the arm to lift, and as a result, Thunder Man has lost the ability to move that arm. It simply hangs limp, un-functional.
