Kamek

Kamek was the main antagonist of Yoshi's Island and a recurring villain in the Super Mario series. He prohecised the coming of the Mario Brothers and decided to kidnap them as infants and turn them to the dark side. However, he only succeeded in kidnapping Baby Luigi, with Baby Mario being rescued by Yoshis. He also raised Bowser, who later became King Koopa.
In Car Wash, Kamek deems Bowser to be a limp noodle and decides to team up with Blue Bowser to take over the world using nanotechnology. Kamek does very little throughout his appearances, and was only there because AwdryFan1997 thought Kamek was cool.
