The World's Greatest Super Friends: The Superfriends Meet Frankenstein

Superman, Batman, Robin, and Wonder Woman fight against Dr. Frankenstein and his creatures. The final product of his experiments results in a evil and terrifying monster made up of the powers belonging to Superman, Batman, and Wonder Woman. Drained of their strength and powers, these Superfriends are no match for the monster. So they combine all their remaining strength and channel it into Robin, who becomes a strong and flying Super Robin. Knowing both he and the monster have the same strengths and weaknesses, Robin shields himself and uses Kryptonite to bring him down. All strength and powers are then returned to the Superfriends, and Dr. Frankenstein is apprehended.
