Doctor Octopus
iteration of the Sinister Six starting with Kraven the Hunter. When Doctor Octopus attempts to turn Norman Osborn back into Green Goblin, he finds that Osborn injected himself with an anti-Goblin serum to prevent further transformations. Doctor Octopus then uses the Siege Perilous to summon the Green Goblin's demonic winged counterpart from Miles Morales's universe and after a brief battle recruits him instead. He bribes Rhino into becoming a spy for him while operating as a student at the S.H.I.E.L.D. Academy in exchange for finding a cure for his condition. When Spider-Man and his team accidentally release the water-made criminal Hydro-Man, Doctor Octopus spares no expense in recruiting him. Doctor Octopus then completes his lineup with Electro. Spider-Man forms his own new team consisting of Agent Venom, Iron Spider, Miles Morales (going by the name Kid Arachnid now), and the newly introduced Scarlet Spider (who has no identity and is later named Ben by Aunt May). It was later revealed that Doctor Octopus actually created the Sinister Seven and that Scarlet Spider was the real spy for him, and unmasks Spider-Man in front of Doctor Octopus, revealing his identity. This leads to Doctor Octopus leading up to his next plot that has him turning against Arnim Zola and captures Aunt May. However, Scarlet Spider has a change of heart at the last minute, he ends up sacrificing himself to save the city from Doctor Octopus.
