Spiky Topman

A Spiky Topman is a sub-species of Topman that appears in Super Mario Galaxy as part of the Topman Tribe. It resembles a large red top with a single spike on its head. A Spiky Topman can use a spin attack which does not damage Mario, but stuns him and knocks him backwards. However, the spin can knock Mario into other hazards that may hurt him. In addition if Mario attempts to stomp a Spiky Topman or lands on one he will be hurt by the spike on its head. Mario can defeat the Spiky Topmen by using their own strategy against them, Mario's Spin attack can knock the enemies into electric fences causing them to explode.

Mario Kart Wii
Spiky Topmen made a return appearance in Mario Kart Wii as part of an online tournament that took place between June 1st to June 9th, 2008. The tournament took place on a special arena known as Galaxy Colosseum, and involved knocking four Spiky Topmen off the edge using Triple Mushrooms.

That competition made a return for June 2009, but the player had to push a total of 6 Spiky Topmen off the stage.
