Doctor Mocha is a villain who once fought members of the Meta Board League (MBL). Little is known about him, except that he carried an energy amplifier in the shape of a small metal disk on his wrist that could manipulate dark energy plasma to create almost any object of hard shadow extending from the hand. He was defeated by unknown members of the Meta Board League, who took his energy amplifier and placed it in the team's second headquarters.
The Lone Survivor (Zed) later discovered Doctor Mocha's energy amplifier in the MBL's trophy room and used it to replace his missing hand.
