Many years ago, a caring orthodontist invented a fantastic device to relieve the dental pain of his patients. Tragically, he tested the device on himself, and as an unexpected consequence, permanently warped his own mind. That kindly orthodontist is long gone and forgotten; now there is only Doctor Mindbender!

This crazed scientist has devoted his time to perfecting brain-scrambling machines, among a slew of other deranged devices. These twisted inventions have found a home in COBRA’s world-dominating schemes, one unhinged mind at a time.

Dr Mindbender is available in the G.I. JOE Heroscape Rumble at the Rift Battle Box!
