Spider-Man: The Animated Series
After defeating the Red Skull, Spider-Man and the team attempt to rendezvous with the Fantastic Four, only to discover that they have been ambushed and that Dr. Doom has kidnapped The Thing. The heroes all go to rescue him, entering Dr. Doom’s empire, which they discover is a peaceful paradise. Doom used the technology of the planet to not only dethrone Doc Ock, but make his New Latverria a place of good; he even gave Thing a watch to switch him back to his normal self. After learning of the Beyonder’s powers, Doom decides to absorb him to ensure eternal peace by banishing the other villains; however, demons pop out of his dreams. Spidey is able to reverse the process, proving Good is superior. Beyonder erases the others’ memories and sends them back to where and when they were taken. He then reveals to Spidey that this was a test to show if he was worthy of the true challenge.
