Rudy

Description
Rudy the Clown is a grotesque-looking monster, whose species has never been revealed. He wears a clown costume, with a yellow suit and a big, round, red nose, but has green skin and wears spiked yellow gloves on his hands. His hands are able to be detached from him, and if Wario were to throw one at his face, it would damage him. He lives in the Music Box World, posing as the God of it in order to be released after being sealed away by the already-cursed inhabitants.

Video games
Rudy the Clown made his first appearance in Wario Land 3, where he lured Wario into the music box world, claiming that he was the God of the world, in order to convince him to help break the seal that was placed upon him by the other creatures of the music box world. He asks him to break the seal, allowing him to keep any treasure that he finds along the way, which convinces Wario. When he defeats all of the bosses in the game and brings the music boxes to Rudy, he emerges and attacks Wario, revealing that he was, in fact, using him to be free, and takeover the music box world and the real world as well. Wario defeats him, and the curse on the other inhabitants is broken. Rudy made a return in the video game Dr. Mario 64, where he and Mad Scienstein concocted a plan to steal the Megavitamins from Dr. Mario. Wario made an attempt at stealing them, but after failing to defeat Mario, Mad Scienstein stole the Megavitamins himself, and both Dr. Mario and Wario chased him down in order to retrieve them, running into many Wario Land 3 bosses along the way. When they encountered Mad Scienstein, they also encountered Rudy the Clown, and if defeated without any past losses, either Wario will face Metal Mario, or Mario will face Vampire Wario.
