Mario Kart: Crossover Craze

It SHOULD be real and for the Wii U, except sadly it isn't, so I'm making a fanon of it.

Story
Unlike other Mario Kart games, this one has a story.

Bowser was working on a plan to kidnap Peach by using a potion that attracts her to him like a magnet, but he gets a recipe from a Magickoopa, but he tries it and it zaps a portal that summons many people from other dimensions. The Magickoopa was a traitor and said that only the master can defeat him in a battle, so Bowser and the people summoned from the other dimension get in a tournament to see who is the the master to defeat Magickoopa, and everyone must battle to see who is.
