Emperor Pilaf (Pirafu) is a small, impish man who dreams of ruling the world. Though he proclaims himself an emperor, he actually only has a crown and a castle. Along with his two minions, Mai, a woman that wears a trench coat, and Shu (Shū), a humanoid dog in a ninja outfit, he seeks out the Dragon Balls to wish for world domination. After obtaining the Dragon Balls once, he is foiled by Goku and his companions after another wish is granted just before he can speak his fully. He continues to antagonize Goku throughout the rest of Dragon Ball, and while attempting to obtain the Dragon Balls, releases Piccolo Daimao from his confinement. They appear again in Dragon Ball GT, where they obtain the Black Star Dragon Balls and accidentally wish Goku to be a child again.
