The Fire Sumo is a lone Sumo Bro. who appears in the Super Mario World TV franchise. He makes his only appearance in the final episode, Mama Luigi. His design is no different from the other Sumo Bros. His name, Fire Sumo, may reference how his species can send fire raining down with their stomping.
Luigi bumps into the Fire Sumo while he and his friends Mario and Princess Peach are exploring the Dome City, which seems abandoned. The enraged Fire Sumo stomps the ground. Luigi falls into a crack that has opened beneath his feet. This sends him into the Lava Pits.
