X-Naut Dude is the X-Naut who says “dude” all the time. He is one of Grodus's friends, and when Grodus wanted to takeover the world Grodus asked this X-Naut if he wanted to join him. He accepted and went to work for him on the Moon. Saying “dude” got to be a habit for this X-Naut, and then everyone called him X-Naut Dude. After Grodus lost to Mario, this X-Naut would play cards with Grodus, Lord Crump, and some other X-Nauts.

Ever since then he has had a pretty good life.
