Generally speaking, if your doctor is wearing purple pants, metal studded suspenders, a blue cape, and no shirt, it's probably best to regard him with a healthy degree of suspicion. Cobra Commander learned this the hard way at the start of the second season of G.I. Joe, when his own shirtless, cape-wearing science officer, Dr. Mindbender, usurped his authority by crafting the ultimate COBRA leader: Serpentor.

Serpentor was grown out of genetic gumbo: by taking the DNA of history's greatest leaders and mixing them all together, Mindbender hoped to create the perfect ruler (or at least one that didn't always call him "Fender-Bender.")

Alas, as is so often the case, Mindbender's plan was thrown off when he was forced to substitute Sun Tzu's DNA with that of professional wrestler Sgt. Slaughter. Because of this, Serpentor was cursed with impatience, a fatal flaw G.I. Joe was able to use against him time and time again.

Even though Mindbender failed with his Serpentor, creating the "Serpentor of [insert profession here]" is still one of my favorite games...
