Sledgehammer Bro. is one of the first of the Hammer Bro. species to appear. He was one of the first Fantendo characters after That One Series With a Long and Uninteresting Name That I Do Not Wish to Remember. In a way, he was much like Mr. Game & Watch. Back in his first (and only) game, his body was all pitch black with a gray outline outside his body, and he moved in frame-by-frame movement, like Mr. G&W. But in the game Fantendo Smash Bros. Rumble (Sledgehammer Bro.'s Smash debut), Fantendo totally revamped his image. But he still moved frame-by-frame.
