The Magician (1999)

Professor Cosmo (1x20)

:

At a science-fair, and later through the city, Cosmo and Black Jack compete for control of a nearly-indestructible robot, until Jack attaches his own motorized chair to the robot, and thus establishes an impenetrable neural interface; whereupon Ace, having originally come to rescue Cosmo, defeats Jack in single combat. Thereafter, Jack claims to have subdued the robot himself, and thus escapes punishment.
