Spooky Speedster

The Spooky Speedster is a character from Super Mario Galaxy. He is a Boo wearing a helmet that will challenge Mario to a race for a Power Star.

Mario first meets him in Ghostly Galaxy, He must use Pull Stars to navigate through the track. He meets him again in the Boo's Boneyard Galaxy. Here, Mario must turn into Boo Mario and must race through a tunnel. When Mario meets Speedster, he calls the Power Star "it", assuming Mario is also after "it". If Mario reach the finish area first, Speedster gives the Power Star.

He is the rough equivalent of Koopa the Quick and Il Piantissimo.
