Scorpion (Mac Gargan)

Origin
MacDonald Gargan was a private investigator who was very successful until Spider-Man came along. Spider-Man was gaining all of the attention and tracking down criminals, helping people for free. This put Gargan out of business and made him despise Spider-Man.

The Scorpion
When J Jonah Jameson wanted to create a hero to beat Spider-Man, the scientist working on the project told Jameson about Gargan. Jonah invited Gargan to take the experiment and he accepted, a suit was forged to his skin, this made him the Scorpion. Jameson had Scorpion fight Spider-Man and they did but Jameson realised when watching this fight that he had created something worse than Spider-Man, so because of this Jameson reluctantly helped Spider-Man by using all of the information about the armour, together they defeated Scorpion and had him arrested...

The Sinister Six
Gargan later joined Doctor Octopus' Sinister Six where he attacked several Oscorp facilities with the help of the Rhino, in order to keep Spider-Man occupied he injected him with a liquid that made him hallucinate. Spider-Man managed to get freed of the hallucinations though and fought against Scorpion and the Rhino, they were both beaten and sent to prison, not for long though...

Full Time Crime & Revenge on JJ
When Gargan broke out of the Raft he turned to crime full time, though his two main objectives were revenge, revenge on Spider-Man and JJ. Scorpion climbed up to the top floor of the Daily Bugle where Jameson was and kidnapped him. Scorpion threw Jameson off a building but he was caught by Spider-Man, Scorpion and the Arachnid fought and Scorpion was defeated and sent to The Raft.

Venom
Later on, when Venom left Eddie Brock, it bonded with Gargan and he became the new Venom. Venom wanted Spider-Man dead and they fought several times while the symbiote was bonded with him. Eventually Spider-Man managed to burn the symbiote off Scorpion's body and it returned to Eddie Brock...
