Doctor Mindbender
He is a scientist who works for the terrorist organization Cobra;
He is often allied with the Cobra Commander and Destro.
Dr. Bender was at one time a peace-loving orthodontist. He built a machine to relieve dental pain, using electric brainwave stimulation. Unfortunately he tested it on himself, and when it went haywire, he became hateful, deceitful, and vain. Though experiencing brain damage, he retained his sense of scientific skill and intellect, unfortunately choosing to use it for the purposes of evil.
Dr. Mindbender abandoned his practice and joined forces with Cobra, devoting all his time to perfecting his digital brain-scrambling. He is a master of mind control and interrogation, but his expertise also includes genetics, cloning, orthodontistry, and some cybernetics.
