Super Mario Blue: An Eggman Rage and Sonic Red: Bowser Goes Crazy, known as Super Mario Fusion and Sonic Fusion in Europe and Super Mario: Waku Waku Tomodachi Daisakusen! (Super Mario: Exciting Friendly Mission) and Sonic the Hedgehog: Waku Waku Tomodachi Daisakusen! (Sonic the Hedgehog: Exciting Friendly Mission) in Japan, are upcoming paired video games for the Wii VR about a crossover between the Super Mario and Sonic the Hedgehog game universes. This game is a spin-off from the Mario & Sonic series. The game stars Mario and Sonic the Hedgehog.


The story begins with Bowser and Dr. Eggman joining forces to rid themselves of their respective enemies Mario and Sonic the Hedgehog by genetically modifying Eggman's "robotic" minions, including Egg Goombas and Klagens, and disguising them as Mario and Sonic, leading the two protagonists to believe they are against each other. Mario and Sonic are alerted of their respective worlds' predicament and are sent to get rid of the disguised robots. Mario and Sonic eventually encounter each other at the Mushroom Kingdom and Mt. Flamethrower, believing each other to be a disguised robot. However, they soon discover that they have been tricked into fighting each other by Bowser and Eggman and decide to team up against them.

Not even Bowser Jr., Rouge the Bat or E-123 Omega can stop them, but Bowser uses his robotic creation of Mario, Armored Mario, and Eggman uses his robotic creation of Sonic, Metal Sonic. Blaze the Cat informs Mario and Sonic what Armored Mario and Metal Sonic have done. Sonic distracts Armored Mario while Mario distracts Metal Sonic. Finally, Mario and Sonic defeat Armored Mario and Metal Sonic at their own game. Knuckles the Echidna has an idea: If they put a tracer on Bowser and Eggman, they would track them to their headquarters. Mario defeats Eggman, but he forgot to insert the tracer. Sonic defeats Bowser and he puts the tracer on him. Mario and Sonic reach their headquarters, where Princess Peach's Castle was transformed into Bowser's Castle by Bowser and Eggman, with the portal from Mario and Sonic's worlds in progress by Miles "Tails" Prower. As a team, Mario and Sonic defeat Bowser and Eggman and rescue Amy Rose and Princess Peach once and for all. They thank each other as the game ends with a photo of Mario having Sonic in a friendly headlock, and the credits roll.


In these games, Mario and Sonic have to travel in 5 different worlds, collecting Power Moons (in Mario's case), defeating the robots (Sonic's case) and fighting the bosses. There are many minigames and the opportunity to trade trading cards.
