The Brain Master was a brilliant scientist who built a machine that could drain knowledge from people and record that knowledge in his own brain. He hoped to learn the secrets of the universe by draining prominent sceintists, and he planned to use his knowledge to rule the galaxy. Unfortunately, his normal sized brain could only take in so much informaiton before it was "full." After draining several great thinkers, he was stopped by Captain Braddon of the Space Legion. The Brain Master was highly intelligent, but not physically very strong. He had a henchman named Gor who acted as his brawn.
