Dr. Otto Octavius has dedicated his warped genius to the eradication of his most hated foe: the Amazing Spider-Man! Dr. Octavius' abilities derive from his four steel tentacles. Attached to a harness encircling his lower chest and waist, each telepathically controlled, telescoping limb can move at speeds of up to 90 feet per second and strike with the force of a jackhammer. Also, Doc Ock is able to generate a 50-mph wind by spinning the prehensile extremities like a giant fan.
The Sinister Six was an alliance of villains sharing one common goal: revenge on Spider-Man. Initially led by Doctor Octopus, the group's lineup consisted of Venom, Kraven the Hunter, Black Cat, Green Goblin and Electro - who had all been soundly defeated by Spider-Man. Doctor Octopus assured his comrades that by working together, they could finally destroy the web-slinger for their mutual benefit.
