Worlds collide in this meetup between two iconic heroes!

When a battle against Doctor Doom goes awry, Spider-Man is transported across dimensions to a Japan where giant monsters known as Kaiju roam and the country is protected by a giant of light—Ultraman! But when two of their worlds’ most dangerous villains form an alliance, will Spider-Man and Ultraman be able to live up to the title of hero, or will they be forced to discover that overcoming evil means sacrifices must be made?
