Doctor Mindbender

Doctor Mindbender began as an orthodontist who experimented with mind-control technology on himself, inadvertently warping his own psyche. He emerged as a brilliant but unhinged scientist who placed his considerable skills in brainwashing and genetics at the service of Cobra.

Few villains in the G.I. Joe universe carry quite the unsettling mystique of Doctor Mindbender, who slithered onto the scene in G.I. Joe: A Real American Hero #44 in 1986, the product of Larry Hama and Rod Whigham's darkly imaginative collaboration. A Copper Age creation through and through, he's spent nearly four decades haunting the pages of G.I. Joe comics, racking up 79 catalog appearances and three collector-significant key issues — a testament to just how deeply he's embedded himself in the mythos. He moves in the most dangerous company imaginable, sharing pages with icons like Cobra Commander, Destro, Snake-Eyes, and Scarlett, placing him squarely at the heart of the franchise's most electric confrontations. If you're building out a serious G.I. Joe collection, Doctor Mindbender is one of those figures you simply cannot overlook.
