'Super' Mario is a hero from the Mushroom Galaxy. He wears a red plumber's outfit and talks in an 'Italian' accent. He stomps on enemies to defeat them. He utilizes miniature portals found in the Musroom Galaxy (that were developed from studying Giratina's portals) to get around. They are painted green and look like pipes or various other plumbing-based objects.
He is constantly trying to rescue Princess Peach from the evil Bowser, a giant mutated tortoise who considers himself Mario's nemesis, but everyone knows Mario has been pursuing Bario, his half-brother, ever since Mario fell into the Mushroom Kingdom with his actual brother, Luigi.
