Eggman and Bowser from the Mario series joined forces to rid themselves of their respective enemies, Mario and Sonic the Hedgehog, by genetically modifying Eggman's "robotic" minions and disguising them as Mario and Sonic, leading the two protagonists to believe they are against each other. The two heroes eventually discover this and work together to defeat the two evil-doers. Instead of fighting one another like Eggman and Bowser had wanted, Sonic and Mario began working together to defeat their archenemies and free the world once again. Sonic eventually ends up tagging Bowser with a transmitter which leads both Mario and Sonic to Bowser and Eggman's headquarters in which Princess Peach's Castle was transformed into Bowser's Castle where they are defeated.

Super Mario: Dimension Journey

In this game he is the main boss of World 2, Angle Island. In phase 1 he plays out like he does Green Hill Zone in Sonic the Hedgehog. During phase 2 his wreaking ball will destroy the two floating platforms used for jumping on him and will instead have to resort to waiting for him to drop to the surface for a chance to land a hit as he is to high up to damage his Egg Mobile with a spin.

Super Mario: Dimension Journey 2

In this game he is the main boss of World 2, City Lights Zone. In phase 1 he is sitting in his Egg Mobile shooting bolts and balls of lightning and electricity to the ground. He will also make platforms move. In phase 2 he will drive in his Egg Limo, chasing down the player. The player has knock back shoot missiles that he shoots with a spin attack. However, he must be defeated quickly because the road the boss and the player is on doesn't continue on forever.

Kirby's Dimension Journey

In this game he is the main boss of World 1, Green Hill Zone. In phase 1 he fights much like he does in Bridge Zone from the Master System version of Sonic 1 and also with a mix of the Fatty Whale boss from Kirby's Super Star. To damage him, the player has to swallow missiles he shoots. Phase 2 makes him more faster and harder to defeat.
