Wizenheimer

Wizardheimer is a somewhat overweight "Koopa Wizard" with a booming voice. Wizardheimer was also the main enemy of the Super Mario World episode "Ghost R Us".

Mario, Luigi and Princess Toadstool first encounter Wizardheimer while searching the Enchanted Forest for Oogtar the Caveboy, who is missing. After bumping into Wizardheimer in the forest, the Koopa Wizard forces Mario, Luigi and Toadstool into a nearby Warp Pipe, threatening to blow the trio up with a Bob-omb if they didn't obey.

This Warp Pipe led to Wizerdheimer's Ghost House, the basement of which he shackled Mario, Luigi and Toadstool in.

Wizerdheimer later captured Oogtar, who had attempted to break-into Wizerdheimer's Ghost House. Wizerdheimer was later defeated when Yoshi, after facing his fears and venturing into Wizerdheimer's Ghost House, eats the Koopa Wizard's wand.

After having his wand eaten, Wizerdheimer was bonked on the head by the recently released Mario and fell unconscious into his basement. What became of Wizerdheimer afterwards is unknown.
