Sir Grodus

He is the supreme leader of the extraterrestrial organization called the X-Naut Legion. He kidnaps Princess Peach and he wishes to capture all of the Crystal Stars before Mario does to unleash the spirit of the 1,000-year-old demon known as the Shadow Queen. His base is located on The Moon.

He can create Mini-Yuxes called Grodus Xs. He requires 4 Grodus X's to create a barrier to protect himself. If a single Grodus X is destroyed, the forcefield breaks.
