All humanoid children of the alien world of K-Shazor have surgery to make their brain hyper efficient. The Brain Emperor (real name unknown) had a mutant brain, which gave him limitless mental powers when the surgery was performed.
He later used his mutant mental powers to become absolute rulers of the planet K-Shazor. A solar eclipse caused a lapse in his mind control powers, during which time the people of K-Shazor over threw the Brain Emperor and imprisoned him in the Cosmo-Cube. After escaping the Cosmo Cube the Brain Emperor came to Earth to conquer the planet.
The Brain Emperor continues to battle the Mighty Crusaders.
