The Skrulls may have been defeated, but they want revenge, so they send a superior genetically modified Srkull - Superskrull - to take down the Fantastic Four.

Dr. Doom imprisons the Fantastic Four in his castle. Sue manages to convince Doom to tell her about his origin, in order to buy time for the other three to find a way out.

Doom continues to indulge Sue by telling her about his past. He is Victor von Doom the son of a helpful local who was wronged by the superstitious locals. Meanwhile, the other three must face Doom's traps on their way out.
