Sledge Bro

Sledge Bros. (sometimes incorrectly referred to as a Sumo Bro.) are large overweight versions of Hammer Bros. that throw sledge hammers instead of regular ones.

''Super Mario Bros. 3
The Sledge Bros. first appeared in Super Mario Bros. 3, where they replace Hammer Bros. in Big Island's levels, as well as on the area's map. If a Sledge Bro. sees Mario or Luigi, it attacks them by throwing sledge hammers at them; additionally, whenever a Sledge Bro. jumps and lands on the ground, it creates a miniature earthquake which can paralyze Mario. To defeat a Sledge Bro., Mario can either jump on it, hit it with a Shell, use a fireball as Fire Mario, or a hammer as Hammer Mario to take it out.

''New Super Mario Bros.
Sledge Bros. reappear in the eighth world of New Super Mario Bros. The Sledge Bros. of New Super Mario Bros. can be defeated by jumping on them, hitting them with a fireball as Fire Mario or by touching them when Mario is empowered by a Star. Like the Fire Bros., they appear in only one level.

''New Super Mario Bros. Wii
Sledge Bros. reappear in the game New Super Mario Bros. Wii as rare enemies, along with Hammer Bros. They are first encountered in World 6, where a pair of Sledge Bros. guard the exit of the cave in the world's second level. They also appear in World 7 in Ludwig's castle.

Strangely enough, Sledge Bros., along with the Fire Bros. again, outnumbered the once common Hammer Bros. in this game, the former being in two levels while the latter only appear in one.

''The Adventures of Super Mario Bros. 3
Sledge Bros. make several appearances in The Adventures of Super Mario Bros. 3, where they are among the elite of King Koopa and the Koopalings' military forces. They are generally portayed as fairly tough soldiers, and manage to pose as major enemies to Mario, Luigi, Princess Toadstool and Toad in many episodes. Much like in the game, Sledge Bros. are able to cause tremors by jumping.

''Yoshi's Safari
In Yoshi's Safari, Sledge Bros. appear as mini-bosses who attack Mario and Yoshi by throwing sledge hammers at them; a Sledge Bro. can also immobilize Mario and Yoshi by stomping the ground. A Sledge Bro. must be hit multiple times with Mario's Super Scope to defeat it in Yoshi's Safari. To avoid being hit, Mario can shoot the sledge hammers that the Sledge Bro. throws, destroying them.

''Mario Kart Wii
In Mario Kart Wii, some Sledge Bros. can briefly be seen in a few sections of the Daisy Circuit, and on a ship in D.K.'s Jungle Parkway, along with other spectators.

Trivia

 * Oddly enough, in New Super Mario Bros., Sledge Bros. are misnamed Sumo Bros., a name previously associated with an unrelated enemy from Super Mario World.
