Part II:"The Traitor the Liar and the Genius"

Synopsis:
The Joker breaks Lex Luthor out of Gotham prison. Luthor then takes the Joker to a hidden cache of loot and weapons. Superman and Batman have followed the crooks, but they are unable to capture them. Luthor then uses a time machine to transport three historical figures from the past into the present to help commit crimes. He summons Benedict Arnold, Baron Von Munchhausen, and Leonardo Da Vinci.

Leonardo helps Luthor build weapons, while Von Munchhausen's lies inspire the Joker to plan crimes. Benedict Arnold serves as a field general for the crooks during their crimes, but he secretly sets Luthor and the Joker against one another. The crooks realize they are being manipulated by Arnold and double-cross him, but Superman and Batman are on hand to capture them all. The historical figures are then sent back to their own time, while the crooks are taken into custody.
