Negario is a negative version of Mario. He first appears in Mario Kart: Nitro Boost as a way to show previous records. He is apparently one of Mario's multiple brothers that walked away onto a rocket and drifted into space, then being crashed into a planet full of ztars. He was then raised by them into being a force of negative power. Even though we was raised that way, he is less evil and more of a jerk. He randomly lives in the nose of Starship Mario. He will someday marry Prancis Peeps.
