Otto Gunther Octavius called himself the Master Planner when he defeated Spider-Man with the team he created called the Sinister Six. When the 5’9”, 245 lb Dr. Octopus was dying, he transplanted his mind into his nemesis, making him realize the responsibility his power came with; when he said he wanted to revert back, it was too late, so to be a better man, Doc Ock became the Superior Spider-Man. One of the best things about the doc is that, most of the time, he was portrayed as an out-of-shape, middle-aged guy with a hilariously bad haircut. Luckily, he had four strong metallic appendages attached to his back. And his accomplishments were nothing to scoff at; he set up the Sinister Six, caused the death of George Stacy, and he actually had the nerve to try to marry Aunt May. And recently, Ock had maybe the most totally insane victory any villain ever achieved: he stole Spidey’s fuckin’ body. Like, permanently. He switched minds with Peter, sticking his consciousness in his own decaying self. Of course, Pete managed to preserve his memories in Octavius’s mind, so it wasn’t a total win but still, taking the body of a superhero for yourself ain’t so bad for someone with a bowl-cut…
