Sir Grodus is an antagonist in the GameCube video game Paper Mario: The Thousand-Year Door. He's an alien and the leader of the X-Nauts, and will also appear as a boss near the end of the game, though he doesn't play the role as the final boss, which is taken by a possessed Princess Peach to whom he kidnapped as an offering to the demon, Shadow Queen. He is destroyed as a result of trying to order the Shadow Queen just before you battle her.
