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.

Tattle: That's Grodus! He's the head of the X-Nauts who kidnapped Peach. But... when he has Grodus Xs surrounding him, his Defense will go up by that number. He may also use electricity, fire, and time-stopping magic. That doesn't sound good! Still, he's a totally weird guy. Why's he so intense and serious all the time? I guess we don't have time to worry about that. Let's beat him and find Peach!
