Pronounced Cross-Nauts. Aliens that work for Grodus and Lord Crump of the X-Naut Legion and they all appear in Paper Mario: The Thousand-Year Door. These guys are short and fat and individually weak, but rush to defend their threatened leader, often Crump.

The X-Nauts come in 3 different varieties:
 * X-Naut Troopers: The lesser X-Nauts, also the weakest. This type of X-Naut has white skin.
 * X-Naut PhDs Scientist X-Nauts. Wears a lab coat and a blue uniform and attacks by throwing chemicals at Mario and his team. Like the X-Naut Trooper, this type of X-Naut has white skin. They also create species called Yux
 * Elite X-Nauts: High-ranking soldier X-Nauts. Unlike the Trooper X-Naut or the PhD, his type of X-Naut has black skin and has red eyes.
