Sledge Bros. (or Sledge Brothers) are large overweight versions of Hammer Bros. that throw sledge hammers instead of regular ones. They can create small earthquakes as well.
They are subspecies of Hammer Bros. They throw large sledge hammers instead of normal hammers and they can create small earthquakes by jumping which can stun the player.
Super Mario Series
Super Mario Bros. 3
In Super Mario Bros. 3, Sledge Bros. can create small earthquakes to disorientate Mario; it stops Mario or Luigi from moving, allowing it to continue to throw its hammers in succession. Mario or Luigi must jump as soon as it hits the ground (after it jumps) to maintain posture. Encountered first on World 4-Giant Land.
New Super Mario Bros. Wii
Sledge Bros. reappear in the Super Mario series after a long time of absence. Their appearance hasn't changed much, however, they do now lack the drop of mucus running down their noses. Their hammers are now considerably bigger which is better fit for their name. Their attack pattern remain the same as it did in Super Mario Bros. 3. Mario can defeat them by either jumping on them or throwing a fireball at them. Ice Mario can also freeze them.
New Super Mario Bros. 2
Sledge Bros. reappear in this game, although in much less levels than in their previous appearance. They retain the same design and attack patterns. Mario can also defeat them just as he did in the previous game. When under the effects of the Gold Ring, just like Hammer Bros, they'll throw Coins instead of Hammers
New Super Mario Bros. U
Sledge Bros. only appear in one level, Ludwig's Clockwork Castle, where they behave exactly the same as they did in the previous entries.
Super Mario Maker
Sledge Bros appears as one of many enemies that can be added in stages of Super Mario Maker. However, they do not appear on the enemy tab itself. Instead, the player must give a Hammer Bro a Super Mushroom in order to turn it into a Sledge Bro.
Mario Party Series
Mario Party 10
A Sledge Bro can be fought as a boss in Party mode of Mario Party 10. One may also be holding the star at the end of Bowser Party if the four players make it to the end of a board.
Paper Mario Series
Paper Mario: Color Splash
Sledge Bros. make their Paper Mario debut in Paper Mario: Color Splash, where they appear as rare enemies with lots of HP and Defense. There is also a sub-boss called Shady Sledge Bro, which is a Sledge Bro with sun glasses. In the Dark Bloo Inn, he wanted to ride on "it" before Mario defeated him and took "it" back.
Paper Mario: The Origami King
Sledge Bros. reappear in Paper Mario: The Origami King, where, like the rest of the enemies in the game, are folded up into origami and serve King Olly. Like in Paper Mario: Color Splash, they have high HP, Defense and Attack Power, and are commonly found within a group of Hammer Bros and Fire Bros.
