Boss Sumo Bro is a Sumo Bro enlarged by Kamek's magic who first appears in New Super Mario Bros. U. He looks like a regular Sumo Bro, but is larger, has his eyes squinted, has a ring around his spike and appears to wear two tsuna around his shoulders, the ceremonial rope typically worn by yokozuna sumo wrestlers around their waists.


Super Mario series[edit]

In New Super Mario Bros. U, a Boss Sumo Bro awaits in the second tower located in Rock-Candy Mines. Boss Sumo Bro was a regular Sumo Bro until Kamek transforms him, somewhat changing his appearance and greatly increasing his size. He is battled in Screwtop Tower.

In battle, Boss Sumo Bro jumps between the floors in the room, stomping them to make electric waves below him in attempt to damage the player. Stomping the ground makes it shake for a few seconds, which may stun the player. Sometimes, he stomps the floor twice.

The Boss Sumo Bro cannot be stomped normally due to the spike on his head; to defeat him, the player has to jump and hit the bottom of the floor where Boss Sumo Bro stands, causing him to fall on the back of his shell. While Boss Sumo Bro is stunned, the player must then jump on him - jumping on the boss three times defeats him. The Note Blocks in the room are quite useful for this.

New Super Luigi U[edit]

Boss Sumo Bro reappears in New Super Luigi U, having the same role from the original game. He is found in his new tower, Sumo Bro's Spinning Tower.

Mario Golf: World Tour[edit]

In Mario Golf: World Tour, a Boss Sumo Bro costume is available for Miis to wear, and they can also use a ball and set of golf clubs designed based on a Boss Sumo Bro.

Paper Mario: The Origami King[edit]

The Boss Sumo Bro appears as a boss in Paper Mario: The Origami King, having been folded into origami by King Olly.

When Mario, Olivia, and Kamek try to enter Bowser's Castle, a thundercloud with the Boss Sumo Bro on top appears and nearly strikes the former two with lightning, closing the path. Bowser Jr. attempts to get to the cloud in his Junior Clown Car, but is cut up by Scissors before he can reach it. If Mario attempts to walk under Boss Sumo Bro's cloud after this, Boss Sumo Bro strikes him with lightning and deals 36 damage. Once Bowser Jr. is restored to normal, the group uses the Junior Clown Car to get onto the cloud, and Mario and Olivia battle them.

When the battle starts, Boss Sumo Bro has moved to a smaller thundercloud, and six regular Sumo Bros appear also on thunderclouds. Four of them will dismount and steal ON, +1, Fire Vellumental, and Attack icons from the battle rings, and taking them to the center. The other two Sumo Bros. will then use Thunder Guard, electrifying the two spaces in front of them; if Mario steps on an electrified space, he is dealt 6 damage and wastes his turn. Mario can attack the Sumo Bros. on foot by ending up in front of them, and must get back the icon they are holding by defeating them. If Mario is not in front of a Sumo Bro, Jump attacks will hit the Boss Sumo Bro and Hammer attacks will do nothing. If a Vellumental is used, it will hit only the enemies on foot; the Fire Vellumental deals 200 damage, instantly defeating such enemies, while the Earth Vellumental deals 100 damage, enough to instantly KO the normal Sumo Bros., but not the Boss Sumo Bro.

As with all spiked enemies, Boss Sumo Bro and his minions cannot be jumped on (except with Iron Boots), but he can be hit with anything else without an issue.

When the enemies attack, the Boss Sumo Bro and Sumo Bros. in the air use Thunder, the Sumo Bros. dealing 10-14 damage each, and the Boss Sumo Bro dealing 26-28 damage. However, if Mario has used the Earth Vellumental prior, he will completely avoid the attacks due to the Sumo Bros. not being high enough to hit him.

After all the Sumo Bros. on foot are defeated, the remaining enemies will dismount, the Sumo Bros. stealing both Vellumental spaces, and the Boss Sumo Bro charging up Heavy Thunder every turn, which deals 40 damage, but can also be avoided using the Earth Vellumental.

  • Boss Sumo Bro is the only boss in New Super Mario Bros. U and New Super Luigi U that does not normally appear on top of the tower in the world map. He does, however, briefly appear on top of the tower after his defeat from the player or if the player is defeated and returns to the world map.
