Spider-Man (villain)

While The Original Spider-Man is a Hero there is also MacDonald Gargan acting as a Villainous Spider-Man and Otto Octavius as an Anti-Heroic Spider-Man

MacDonald Gargan
Norman introduces Gargan and the symbiote as the Amazing Spider-Man in his new Avengers. During their first mission against Morgana le Fay, Morgana transforms "Venom-Spidey" into a giant, demonic monster who then tries to eat Ares. Venom later coughs up Ares, however Morgana's magic affects Venom, causing him to lose and gain control of himself randomly. After Morgana is defeated in the past by Iron Patriot and Doctor Doom, Mac returned to his "Spider-Man" form with only a slight headache. Hawkeye promised to kill Mac one day for trying to eat him while he was under Morgana's control. Once they arrive home, he is seen arguing with Hawkeye.

Later, attempting to find out Norman Osborn's plans for his son Harry, the real Spider-Man, with the aid of the Invisible Woman, manages to capture Gargan by using a sonic generator and takes his place to infiltrate the Dark Avengers. Gargan is thrown into the Negative Zone, but is later seen back with the Dark Avengers.

Against Osborn's wishes, Gargan is seen heading out into the city to "fight crime" solo. At one point, he is seen defeating a bank robber called General Wolfram. After making out with two girls at once and getting cheered by a large crowd, he takes the robber to an abandoned roof top and consumes his arm. He then takes the money Wolfram stole and swings away. Gargan is then seen at a strip club with the money and discovers his new favorite stripper. After getting reprimanded by Norman Osborn for eating Wolfram's arm, Gargan kills the stripper and places her dead body in J. Jonah Jameson's bed while he is gone in an attempt to frame him for her murder. At the same time, Redeemer visits the injured General Wolfram and recruits him alongside other villains who have had limbs bitten off by Gargan (namely Dementoid, Doctor Everything, Eleven, and Hippo) in a plan to take down "Spider-Man" (who is believed to be the root of their problem).[57] In another attempt to antagonize Jameson, Gargan instigates a turf war between two rival street gangs, hoping to wear Jameson down through stress and exhaustion from continuously putting out stories to cover the crime wave. At the same time, the Redeemer arms his group with cybernetic limbs to defeat Spider-Man. J. Jonah Jameson goes to Osborn for help and is given Spider-Man to help solve the city's gang problem Jameson first goes to Osborn, who decides to cut Gargan loose by sending Bullseye and Daken (in their old costumes) to kill him. At the Big Apple Festival, the two attack him, with Dementoid, General Wolfram, and both gangs involved in the turf war entering the fray to try to kill Spider-Man. Gargan ends up defeating all of them, and J. Jonah Jameson shoots a gun in the air to stop the fight. As a result, everyone credits Jameson and Spider-Man with successfully working together to stop criminals and save the festival. Gargan later returns to Avengers Tower, where he is visited by Norman Osborn. Osborn informs him that Bullseye and Daken will get over being hurt, but warns Gargan that if he goes out of control again, he will suit up as the Iron Patriot and take care of him personally.

During the opening chapter of Utopia, the Dark Avengers are sent into San Francisco to quell the mutant riots and battle any X-Men they can find. Tension is shown to exist between the Avengers and Osborn's own Dark X-Men. When Namor and Emma Frost are revealed to be double agents on Cyclops' side and defect with Cloak and Dagger, an irate Osborn gathers the Dark Avengers and the remaining Dark X-Men, Gargan included, ordering them to bring him Namor's head and Emma Frost's heart and to make sure that Cyclops sees them do it.[61] The Dark Avengers and Dark X-Men attack Utopia and battle the X-Men, with Venom facing off against Colossus. However, due to the sheer number of X-Men, Osborn is forced to retreat when informed that the only way to win would be to kill all the mutants on the island, an option which is not politically viable.

Gargan later begins to show signs that his medications are making him emotionally unstable. On a mission with the Dark Avengers, Osborn takes Gargan off the case when he notices Gargan's outbursts Molecule Man turns Gargan and his symbiote into an inert pile of goo. He is later restored by the Sentry.

During the "Siege" storyline, Mac Gargan is with the Dark Avengers when Norman Osborn makes plans to invade Asgard. Mac Gargan and the rest of the Avengers protest. For fighting alongside the Initiative, Osborn promises to give the team their freedom from servitude. As a result, Gargan is among the mass of soldiers to launch an attack on Asgard following Loki's setup. He and the rest of the Avengers manage to overwhelm Thor. While fighting Ms. Marvel and Spider-Man after they arrive, Gargan is forcefully removed from the Venom symbiote, which takes over Ms. Marvel until Spider-Man defeats it. He along with the other Dark Avengers were arrested after Norman Osborn fell from power.

Otto Octavius
Within Peter Parker's body, Doctor Octopus starts his new career as a hero by redesigning his gear and putting his past as a villain behind himself. However, he soon finds himself the target of several villains, such as an Octavius-tech enhanced Stilt-Man, Boomerang, Overdrive, Shocker, Speed Demon, the unnamed female Beetle, Living Brain, and all of them trying to take over the place left by the seemingly dead Otto Octavius and his Sinister Six. While they're still no match for the new, more ruthless Spider-Man, his violence and new mannerisms start to tip off several of his close friends and allies, such as the whole Horizon Labs, Daredevil, Wolverine (who is explicitly forbidden to have Spider-Man's mind telepathically scanned under the threat of legal action in court),[61] Mary Jane,[60] and Carlie Cooper.

Despite his accomplishments, Otto Octavius is revealed to be still haunted by the lingering spirit of Peter Parker, unable to reassert control over their shared body, but actively hampering his efforts to stray from Peter's values, and trying to reclaim his body. Despite Peter's lingering influence, Octavius' refusal of Peter's values and perceived screw-ups prompts him to "rectify" some mistakes: the "new" Peter enrolls back to college, pursuing actively the PhD Peter denied himself in the past, and breaks the self-imposed "no-kill rule" by taking a proactive stance against evildoers and criminals, shooting the villain Massacre even after Massacre appeared to show signs of recovering from the brain damage that motivated his crimes, and violently assaulting Jester and Screwball for a relatively minor insult. These actions prompted the Avengers to confront 'Spider-Man' about his recent activities, recognizing that their friend would never act in such a manner. When their subsequent analysis confirms that he is still biologically Peter Parker - the team's resident geniuses being otherwise occupied and thus unable to make more detailed analysi- Otto explains that he is merely dealing with stress over recent events, Peter's attempt to scrawl a picture-warning failing. After Otto saves a child who was brain-damaged during his assault on Earth using a neurological scanner, he reveals that he is aware of Peter's presence and intends to perform a 'Parker-ectomy' to remove what remains of Peter's mind from his brain.

Attempting a mind wipe of all Parker's memories to destroy Parker completely, Doctor Octopus managed to delete the memory of the Daily Bugle. Realizing Peter would not surrender, he directly engaged Parker in his mind. After beating Parker to a pulp, breaking his spirit with the knowledge Parker was willing to sacrifice a girl to keep Otto from finding him. Doctor Octopus declared his final victory, calling Parker unworthy to be called Spider-Man, and deleted all of Parker's memories. Returning to the real world Doctor Octopus rejoices from the fact he is free from Parker, as he achieves victory over the Amazing Spider-Man. However, this erasure has also deprived him of Peter's memories, leaving it more difficult for him to pose as Spider-Man, with some of Peter's friends - such as Carlie Cooper, Mary Jane, and J. Jonah Jameson Senior - questioning Spider-Man's more brutal approach.
