The Mentor is the artificial intelligence of a super-computer designed and created by Dr. Stuart Gordon Power, who operates the Power Base from which The Soldiers Of The Future conduct their operations against the Bio-Dread Empire. He appears visually as a type of holographic image of Dr. Power himself, which is not by accident. The purpose of Stuart Power's creation of this computer, and the programming of its artificial intelligence, was so that his son Jonathan would never be without his father.
The Mentor has links to every computer on Earth, and he can give the Power Team up-to-the-second information.
Data cards for the Bio-Dread Empire character toys described the characters as being on "The Mentor File Wanted List."
