Spider-Man teams up with the Avengers to fight Doctor Doom in New York City, but after a building collapse causes civilian deaths, he becomes disheartened and is taken aboard an alien vessel known as the Interdimensional Train. Doctor Doom also boards and is transported with him to Tokyo in the Ultraman universe. There, they observe Ultraman fighting a massive Kaiju. Impressed by the Giant of Light’s abilities, Doom allies with Alien Mefilas and his Kaiju forces from the Monster Graveyard to seize that power.
