- Vulture. Replaced Mysterio.
The Kingpin sprang the six supervillains from prison, as he required their services to finally rid himself of Spider-Man. Kidnapping May Parker, the Six hoped to get Peter Parker to lead Spider-Man into a trap. After a battle with a powerless Spider-Man, they unmasked him. Believing Peter to be a fake, they again used him in hopes of luring Spider-Man.
After they were unsuccessful in defeating Spider-Man, they spilt up and concentrated on their own, solo efforts. When Kingpin devised a new plan for world domination, he once again called on the six, replacing the late Mysterio with Vulture. After helping Fisk locate the six keys required for the Doomsday Weapon and helping create Electro, the Six again split after The Kingpin was almost killed by the master of electricity, never to reunite again.
First version of the team outside the comics.
The name was changed from the Sinister Six due to censorship concerns. The censors felt the word "sinister" was too intense of a word for a children's show, a backlash to the violence in Mighty Morphin Power Rangers, despite X-Men using Mister Sinister. In 2009, John Semper, Jr. offered an alternative theory. He suggested that since Kraven the Hunter was not a villain at the time while Sandman and Electro were not going to be used then that it was not the true Sinister Six so this team would be a precursor to the real one.
In the Comics
Doctor Octopus initially formed the team. Sandman, Green Goblin, and Hobgoblin have all formed their own versions.
Doctor Doom, Lizard, and Green Goblin were asked to form the original Six but all refused. Doom wanted to spend his efforts on the Fantastic Four, Goblin felt he could do defeat Spider-Man on his own, and Connors had no reason to stop Spider-Man when not the Lizard.
