The Cybernetic Leader (a.k.a. Supreme Brain) is a rebellious being and the supreme ruler of the Kingdom of Cybernetics on the Automated Planet, where he rules over a society of free robots from all over the galaxy.

The Leader and his loyal subjects consider cybernetic life superior, and believe that organic life is suitable for manual labor only. While presumably robotic in nature, the Leader's appearance is that of an inflated amorphous mass with numerous short tendrils.
