Doctor Octopus

Doctor Octopus (Dr. Otto Gunther Octavius), also known as Doc Ock for short, is a fictional character appearing in American comic books published by Marvel Comics. He is a highly intelligent, myopic, and somewhat stocky mad scientist who sports four strong and durable appendages resembling an octopus's tentacles, which extend from the back of his body and can be used for various purposes. After his mechanical harness became permanently fused to his body during a lab accident, Octavius turned to a life of crime, and came into conflict with the superhero Spider-Man. Since his debut in The Amazing Spider-Man #3 (July 1963), Doctor Octopus has endured as one of Spider-Man's most prominent villains, and is regarded as one of his three archenemies, alongside the Green Goblin and Venom. He is the founder and leader of the Sinister Six, the first supervillain team to oppose Spider-Man.

While usually portrayed as a villain, Doctor Octopus has also been occasionally depicted as a conflicted antihero and ally of Spider-Man. Following Spider-Man's death in the 2012 storyline "Dying Wish", which saw a dying Octavius swapping bodies with the hero and letting him die in his original body, Octavius became motivated to prove he can be a better Spider-Man. As such, he adopted the Superior Spider-Man alias, which was introduced in Avenging Spider-Man #15.1 following a cameo in Daredevil vol. 3 #21 (both December 2012). The Superior Spider-Man possesses all of the original Spider-Man's abilities, memories, and equipment, along with additional gadgets created by Octavius, though he often struggles to live up to his predecessor's legacy and turn his life around after being a villain for years. In 2013, Marvel launched a 45-issue The Superior Spider-Man comic book series focusing on the character's redemption and superhero career. The original Spider-Man has since been resurrected and Octavius returned to his villainous ways, though a second volume of The Superior Spider-Man launched in 2018 saw the character briefly taking on the mantle once again.

A fan favorite character and well-known figure in popular culture, Doctor Octopus has been featured in various media adaptations of Spider-Man over the years, including feature films, television series and video games. Alfred Molina portrayed the character in Spider-Man 2 (2004), and reprised the role in Spider-Man: No Way Home (2021), set in the Marvel Cinematic Universe. Kathryn Hahn voiced a female version of Doctor Octopus in the 2018 animated film Spider-Man: Into the Spider-Verse. Comics journalist and historian Mike Conroy writes of the character: "Created by Stan Lee and artist Steve Ditko, Doc Ock, as he became known, has become one of the web-slinger's most persistent, enduring, and dangerous foes." In 2014, IGN rated Doctor Octopus as Spider-Man's greatest enemy.

 * Otto Octavius / Doctor Octopus appears in Marvel's Spider-Man: Webbed Champion, voiced by Scott Menville. His history in the show is the same as in the canon version. He serves as the primary antagonist of the first arc "City of Heroes", on which Octavius (after a battle against Spider-Man and Lady Octopus) had his consciousness to be transferred into cyberspace via the Neuro-Cortex, relocating himself into the Living Brain in the progress. He eventually begun operating as the Master Planner, manipulating a series of events to lure Spider-Man to his trap. In the episode "Brainstorm", his plan to relocate himself into Spider-Man's body eventually backfired when Spider-Man's armor optics (powered by Vibranium provided for Spider-Man by Black Panther) absorbed Octavius's consciousness and returned him back to his inactive body. From there, Octavius (while incarcerated back to the Cellar) attempted (but failed) to remember the codifications of the Neuro-Cortex and be rid of his memories from the past, such as his shame of remembering a failed experiment which rendered Carlie Cooper paraplegic. In "An Eye in the Sky", he broke out of his cell, retrieved his tentacle harness, and sought to retrieve the Neuro-Cortex himself on Horizon High, unaware that his tentacle harness was also being used as a beacon for Ronan the Accuser's Kree armada. He was eventually stopped by Spider-Man's friends (with Ghost-Spider and AC-5 / Ace knocking him unconscious) and (after Ronan was vanquished) returned to prison. In "Seeds of Life", Octavius was broken out of his cell by Kraven the Hunter, and brainwashed as Madame Masque's servant until Spider-Man's team and the Avengers defeated her, rendering her powerless and freeing Octavius, who was also rendered physically disabled and mentally ill in the progress. Despite not appearing in the "Legendary Universes" arc, Octavius's tentacle harness did make an appearance in "Part 3: Unlimited Speed", on which it had been discarded by Oscorp's scientists in Sonic the Hedgehog's dimension, and fell in possession of Dr. Robotnik's former lieutenant EggRobo, prompting Spider-Man and his teammates to team up with Sonic and the Mobian Freedom Fighters in defeating EggRobo and destroying the harness.
 * Doctor Octopus returns in Marvel's Superhero Adventures: Infinity War, voiced again by Scott Menville. Still physically and mentally disabled in a mental hospital since his latest defeat by Spider-Man and the superheroes, Doctor Octopus was broken out and captured by Nighthawk, who restored Octavius's mental health, but only for him to be brainwashed as a slave for Thanos, who merged him into the network walls of his space-station, the Sanctuary II, and used him and the DNA of a likewise captured Venom to create the Klyntauri. In the film's climax, he is freed from his brainwashing with an electroshock blast on his head by Spider-Woman, freeing the brainwashed Black Order members and stopping the production of Klyntauri in the process, although Octavius is not freed from the network walls. As an last act for redemption, Octavius uses the space station's power to teleport the Klyntauri back to the Sanctuary X, and later Thanos, Venom, and all the space station into oblivion, seemly sacrificing himself.
 * Doctor Octopus returns in Marvel's All-Star Multiverse, with Menville reprising his role. Appearing in "Lost Odyssey", he is revealed to have survived his apparent death during the war against Thanos and freed himself from the Sanctuary X network walls after being transported to Exegol. However, he was later held prisoner of Ultron, who proceeded to use his knowledge of Earth's technologies for his plans to eradicate universal life. He is soon discovered and freed by Spider-Man, Sonic the Hedgehog, Iron Man, and the Teenage Mutant Ninja Turtles, and (after Ultron is destroyed) taken to S.H.I.E.L.D. to be treated on.
 * Doctor Octopus also appears in Marvel: All New, All Different Chronicles, voiced by C. Thomas Howell. He is a former Oscorp scientist who worked to perfect prosthetic limb technology and became a super-criminal called the Master Planner after four mechanical appendages were permanently attached to his back during an accident in his lab (it turned out to be an sabotage by Quentin Beck as an attempt to win Norman Osborn's appreciation) which also killed his wife Rose, using an intra-cranial neural network to connect them to his nervous system. He was also once a brilliant, but neglectful science teacher in Midtown High School until he was fired and arrested after being exposed to public eyes by Spider-Man and his LMD (disguised as Peter Parker) for his crimes. After being broken out of his cell by Madame Masque and becoming a member of her Shadow Council, Octavius now operates in the alias of Doctor Octopus (or Doc Ock for short) while he still longs for revenge on Osborn for ruining his life.
 * Doctor Octopus appears in Marvel/DC Heroes Unite!, voiced by Fred Tatasciore. He serves as a boss in the main story, and as a playable character in the DLC story "Sinister Squads".
 * Doctor Octopus is an antagonist in Marvel's The Avenging Spider-Man, with William Salyers reprising his role.
