The country of Melcon wants their own giant robot, and Giant Robot's birthday is spoiled by the news. The Melconians build Cleopat, but Goldenaut steals it. Gargoyle scientists can't activate Cleopat, but the robot's reaction defense disables Giant Robot by using his own attacks against him. Even blinded, Giant Robot defeats Tentaclon and throws it at Cleopat, destroying them both.—empathy44
