Thanos uses the Infinity Gauntlet to create Battleworld, a planet made up of a patchwork of different world-continents where he has encapsulated all possible threats from across the Multiverse in Thanostones.

The heroes split up to explore this strange planet and Iron Man travels to Ultron City where he encounters Ultron, and his dangerous Drone Swarm.

Throg journeys to another part of the Battleworld called New Quack City, where he must battle a new foe: the nefarious Pork Grind.
