Artelius (アルテリオス)[2] is a Nintendo Family Computer action role-playing video game that was released exclusively in Japan on November 13, 1987.

Ruled by the diabolical king Sarbelor, he controls a machine that has split the universe into spaces filled with asteroid belts.

A cyborg has been built by a scientist named Dr. Rado in order to defeat Sarbelor; only he has been entrusted with this mission to save Artelius from the evil king's reign.

Players begin the game by customizing and modifying the traits of their characters.

Having a high level of agility allows for more frequent successes in running away from unwanted battles.
