Sinister Six Members Ranked By Intelligence

Although he's known as one of Spider-Man's greatest foes, the original Green Goblin (Norman Osborn) was never a part of the early lineups of the Sinister Six. This changed in "Marvel Knights: Spider-Man" when he formed his own team while he was still incarcerated. But while previous versions had limited themselves to six members, Osborn eschewed alliteration in favor of firepower by founding the Sinister Twelve.

In terms of muscle, this team was pretty scary. As if having a psycho as the Green Goblin wasn't bad enough, Spidey also had to battle Hydro-Man, Lizard, Sandman, Tombstone, Vulture, Shocker, Hammerhead, Electro, Boomerang, and the Chameleon. Even worse, longtime Spider-Man foe Scorpion was also on the team and had given himself a power upgrade by becoming the new Venom.

Brilliant as Osborn may be, his volatile state of mind also causes him to make some questionable choices. Nowhere is this better illustrated than in the much-ridiculed "Spider-Man: Turn Off the Dark" musical, where Osborn builds a new Sinister Six from scratch by mutating research scientists into becoming new versions of Carnage, Electro, Lizard, Swarm, Kraven the Hunter ... and a woman made of knives that he calls "Swiss Miss." You're a smart guy, Norman, but creating a singing and dancing Sinister Six is just plain stupid.
