Topmaniac's Daredevil Run

Topmaniac's Daredevil Run is the fourth mission of the Battlerock Galaxy in Super Mario Galaxy. The mission can only be done while a Daredevil Comet is in orbit. The mission's objective is to fight Topmaniac when Mario has only one health.

Instead of going through the entire mission of Topmaniac and the Topman Tribe, the player starts immediately on the bottom of the saucer where Topmaniac is fought. The method of defeating Topmaniac remains the same as in the original mission, though Mario will instantly die if he touches any electric rails, Amps, Topmaniac's saws, or the spikes on the Spiky Topmen. Knocking Topmaniac into the electric fence three times, by first jumping on him then spinning to knock him around, will reward the player with the Power Star.
