Sir Grodus

He is the supreme leader of the extraterrestrial organization called the secret society of the X-Nauts, which consists of X-Nauts, a band of thugs determined to capture the Crystal Stars before Mario, so they can dominate the world with the treasure behind the Thousand Year Door. He kidnaps Princess Peach to use her as an offering to the treasure behind the Thousand-Year Door, the 1,000-year-old demon, the Shadow Queen. After the Shadow Queen annihilated him, he was still alive, only his cranium was the only active thing in his body. His fortress is located on The Moon.

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

Goombella's 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!
