After defeating Bowser, the Mushroom Kingdom celebrates until it’s all undone by Wario, an old rival of the Mario Bros, along with his allies, Waluigi, a purple clad mischief maker, Wart, the evil king of the realm of Subcon, and Tatanga, an alien invader from outer space. The group takes Princess Peach hostage and takes their plan to the center of the universe, where Wario is actually planning to create his own galaxy to help him become the richest man ever. Now the Mario Bros, now with the aid of Rosalina, the Queen of the Cosmos.
