Vulture

Adrian Toomes is the former owner of Toomes Salvage Company, based inside New York City, who chose to be a criminal after he lost his livelihood when the Department of Damage Control, a joint venture between the federal government and Tony Stark, was created. Recruiting his co-workers and equipping himself with a flying exo-suit created from the Chitauri technology he had stolen, Toomes took on the identity of Vulture and spent the next four years stealing advanced weaponry to sell on the black market. Toomes' activities were noticed by Spider-Man, forcing him to hunt down the young hero. During their final clash, Peter Parker saved his life, when he really didn't have to. So Vulture decided that he would not reveal his identity to anyone, but he would still attempt revenge..

About eight months after these events, he was recruited for a team dubbed as the Sinister Six by the enemy that saught to destroy (Spider Man). But ultimately, the team was defeated, read about this at The Rise of Six!

Years after this, Toomes was unable to escape due to him being sent to the Raft. But on the outside world, Norman Osborn was running for president and succeeded. He planned a "rehabilitation program" for powerful villains such as Toomes. The program was obviously a ploy for Norman to get villains to rule New York. Read more about this on Avengers: Dark Reign
