Dragon Ball GT - episode 22 - 13 Aug, 1996

Dr. Myuu's special creation is an evil robot named Baby. Trunks has deactivated Baby's life support. While Dr. Myuu tries to revive his creation, Trunks explains that when he was transmitted to the tower as a metal block, Giru freed him, and then created a replica that he transmitted to Dr. Myuu's lab. Meanwhile, the evil scientist has revived Baby, and the robot bursts out of his container. Goku, Trunks, and Pan immediately blast him, and when the smoke clears, Baby is gone. Dr. Myuu runs to his spaceship and takes off. On the ship, Baby bursts out of Dr. Myuu, revealing that he used the scientist to create him. He crushes Myuu's head, revealing the one-star ball inside. (Source: Wikipedia)
