Topmaniac

Topmaniac is a boss who initially appeared in Super Mario Galaxy for the Wii. In the video game, Mario or Luigi, depending on who you were playing as, had to spin attack the boss in order to make it smash into the electrified fences. Once either of the brothers performed this task a certain number of times, then the boss would ultimately be destroyed.

The boss, whose name is influenced by a top (which the boss looks like), will be fought a total of three times in the video games, each one being more challenging than the last. The third time you fight it you won't be allowed to loose one bit of health.

Other appearances
Topmaniac also appeared in Mario Kart Wii for the Wii. In the game, he was a boss that the player had to knock over the edge by using Mushrooms. In the final battle, the character was required to knock over two Topmaniacs.
