Doctor Octopus

"Spider-Man was trying to stop my fusion reactor, so I stopped him. I had him, by the throat! And then I... and then I was here."

- Doctor Octopus

Doctor Otto Gunther Octavius is a nuclear scientist and inventor who created a set of mechanical limbs to help him control fusion reactions. Unfortunately, the tentacle-like limbs were fused to his body in a lab accident, and their artificial intelligence began to corrupt Octavius's brain. This mental corruption led Octavius to pivot toward criminal activity to fund the creation of a new fusion reactor. Nicknamed Doctor Octopus for his eight-limbed appearance, he clashed with the friendly neighborhood Spider-Man. Doctor Octopus was ultimately defeated by him, before choosing to drown the reactor and himself in the rivers of New York City. However, due to a failure in Doctor Strange's spell, Doctor Octopus was transported alive through the Multiverse, ending up in a different universe.

Doctor Octopus encountered that universe's version of Spider-Man and battled with him, but was defeated and sent to the New York Sanctum. However, he would be freed after Spider-Man learned of Doctor Strange's intention to send Doctor Octopus, along with other villains, back to their home universe to meet their fatal destinies. Spider-Man managed to release Octavius from his tentacles' artificial intelligence. Later, Octavius assisted Spider-Man, joined by the friendly neighborhood Spider-Man and another Spider-Man, in their fight against Electro, Sandman, Lizard, and the Green Goblin on Liberty Island. Finally, after all of the villains had been cured, Doctor Strange sent Octavius back to his home reality, alive and well.

Early Life
Otto Octavius was a brilliant scientist who worked towards researching and building a sustainable fusion power reactor. He met Norman Osborn and became his friend, he eventually heard Osborn was the Green Goblin and that he had died fighting the friendly neighborhood Spider-Man.

To build his fusion power reactor and perform a successful experiment, Octavius developed a set of artificially intelligent mechanical arms, which were bonded to his spinal column. When the neural inhibitor chip which prevented the advanced AI of the arms from influencing Octavius' own mind was destroyed, the arms began to corrupt Octavius' mind, playing on his vanity and ego, and he decided to complete his experiment at any cost, being given the name Doctor Octopus. He eventually became an enemy of Spider-Man and fought him on several occasions.

In their final battle, Spider-Man tried to stop his machine and Doctor Octopus had him by the throat before he managed to take control of the arms with the help of Spider-Man, and drowned himself with his machine, which had become unstable. His death was reported by the media, and the event was heard by Flint Marko.

Meeting Alternate Spider-Man
"Hello, Peter." "...Hi? Do we— do I know you?"

- Doctor Octopus and Spider-Man

In 2024 of another universe, Doctor Strange tried to cast the Runes of Kauf-Kaul to make everyone forget Peter Parker was Spider-Man. However, the spell failed and connected to other realities in the Multiverse, bringing people who were aware of Spider-Man's true identity from those to their universe. As time was scrambled, people who were originally dead in their universes were brought alive to this one, one of them being Doctor Octopus. Doctor Octopus, upon entering the other universe, fell under his mechanical arm's control once again. Octopus tried to find the fusion reactor, and eventually encountered that universe's Spider-Man, but not realizing his situation, demanded to know what happened to the reactor as he attacked him. During the fight, Doctor Octopus removed a piece of Spider-Man's Iron Spider Armor, and integrated the nanotechnology into his tentacles. He then attempted to kill Spider-Man, who removed his mask to restore the torn piece of his armor, leaving Doctor Octopus confused as he realized this was not his Peter Parker. The integration of the nanotech into the tentacles allowed Spider-Man to use his armor to take control and turn them against Doctor Octopus. As they both tried to make sense of their situation, they were interrupted by the arrival of the Green Goblin, whom Doctor Octopus recognized as Norman Osborn, before they were transported into the New York Sanctum by Doctor Strange, who placed Doctor Octopus in captivity with the previously discovered Lizard. While imprisoned, Doctor Octopus was introduced to the current universe Peter Parker's friends, Ned and MJ. Though annoyed and still confused at his situation, he offered information on Norman Osborn, including his death years before from Doctor Octopus's perspective. After Spider-Man had gathered Electro, Sandman, and Norman Osborn (who had been found by his Aunt May), Doctor Octopus explained to a confused Norman that he had died some years beforehand while fighting Spider-Man, only for Sandman to then reveal that Doctor Octopus himself had died fighting Spider-Man. When Doctor Strange attempted to send the villains back to their dimensions to meet their fates, Peter incapacitated him and promised to help the villains. Doctor Octopus was surprised that Peter would go out of his way to do so, arguing that it would be easier to just leave them to their fates. MJ retorted that wasn't what Spider-Man does.

Finding A Solution
"It's so quiet. Those voices, in my head... I'd almost forgotten..." "Otto." "Yes. Norman. It's me."

- Otto Octavius and Norman Osborn

After being brought to an apartment owned by Peter's friend, Doctor Octopus was informed that he was the first to be worked on as he protested that he didn't need fixing. He ultimately had to suffer through the humiliation of not being able to fight back, including letting Aunt May offer him a glass of water. Peter and Norman were able to create a new inhibitor chip made from Stark Industries technology which they installed on the back of his neck. The chip worked, restoring his mind and reverting him back to the kindly Octavius for good. In gratitude for Peter's help, Octavius gifted him a brand new suit, made from the same nanotech that the tentacles absorbed from his suit during their fight on the bridge, then asked how he could help him and Norman. However, shortly afterwards the Green Goblin persona took over Norman, unknowingly prompted by Octavius's comment that Norman would be back to normal. After the Goblin manipulated the other villains into turning on Spider-Man, Octavius attempted to stop them but was incapacitated by Max Dillon, who knocked him out of Happy Hogan's apartment window when he grabbed an Arc Reactor. Managing to break his fall with his tentacles, Octavius swiftly retreated from the scene, hopping across buildings as J. Jonah Jameson watched and recorded for The Daily Bugle.

Battle at Liberty Island
"Leave them. They're mine." "I don't need your help. I got this guy." "Dr. Octavius! No!"

- Otto Octavius, Electro, and Spider-Man

Octavius intervened in the battle at the Statue of Liberty by tricking Electro and the other Peter Parkers into thinking he was once again Doctor Octopus, only to use his arms to remove the Arc Reactor and attach Electro's cure to him. He marveled at the reactor, amazed that someone in this universe had achieved what he hadn't: "the power of the sun in the palm of [his] hand." He then had an emotional reunion with his universe's Spider-Man, who he noted had grown since the time they'd last met. When he asked how Peter had been, Peter responded that he was "trying to do better", calling back to their first conversation, which Octavius remembered. After the Green Goblin reappeared to attack them and steal the Machina de Kadavus, Octavius attempted to stop him, but one of his tentacles was severed by the Goblin's glider. As the scaffolding around the Statue of Liberty began to collapse as a result of the fighting, Octavius carried a now-cured Dillon down to safety.

When Doctor Strange cast a new spell that would make everyone in that universe forget about their Peter Parker existence's, Octavius, Osborn, Marko, and their Parker were sent back to their universe just before the spell was completed, with his fate altered.

Personality
"I told you, I don't need fixing!"

- Doctor Octopus to Spider-Man

As Doctor Octopus and being under the thrall of his tentacles, Octavius possessed a bitter, hostile, and stubborn temper with a mind difficult to reason with. Since he originated from a universe with technology less advanced than the main reality, Octavius, though aware of nanotechnology, underestimated its capabilities when he lost control of his tentacles after Spider-Man controlled them with nanotech. Despite his troubled mind, Octavius was not beyond reason, providing information about Norman Osborn to the main reality Peter Parker and his friends and later reluctantly accepting a glass of water from Aunt May.

Once he regained control of his mind, Octavius is shown to be a cordial and ambitious scientist who holds a genuine respect and fondness towards the Peter Parker from his universe. Also, Octavius has come to respect the main reality Peter Parker for freeing him from his tentacles control and did everything he could to help those he considers his friends. However, Octavius will not hesitate to attack his friends if they are not in right mind or turned against him and his other friend.

Powers

 * Cybernetic Enhancement: Octavius created a set of long, mechanical limbs that attach to his back, each equipped with a red camera lens and three claw-like grips.
 * Superhuman Strength: Doc Ock vs. Iron Spider.png Each tentacle has superhuman strength, which allows Octavius to easily overpower humans, rip metal objects and lift cars, allowing him to be a match for Spider-Man. His tentacles were also strong enough to restrain the Green Goblin's glider.
 * Superhuman Durability: The tentacles are super durable, with very few things able to affect them. However the Green Goblin's glider's blades were sharp enough to cut one of Octavius' tentacles off, leaving him with three remaining tentacles.
 * Superhuman Speed: The arms allow Octavius to move rapidly over any terrain and to scale vertical surfaces and ceilings.
 * Superhuman Agility: The reaction time and agility of his mechanical appendages are enhanced far beyond the range attainable for normal human musculature.
 * Superhuman Reflexes: The arms can react to attacks quicker than a regular human.
 * Wall-crawling: The arms are powerful enough to allow him to walk up sheer concrete walls and move about quickly by penetrating themselves into a walls surface.

Abilities

 * Genius-level Intellect: Octavius is a genius in the field of atomic physics.
 * Master Scientist: Octavius is a master scientist in the field of atomic physics, almost successfully being able to uncover the secret of clean nuclear energy in his universe.
 * Master Engineer: In his universe, Octavius created both a powerful fusion reactor and his signature tentacles with their own functioning A.I. system in them so they can adjust to higher temperatures as needed.
 * Expert Tactician: Octavius is a skilled tactician. This was proven when Octavius pretends to side with the villains and try to trick Electro then successfully give a cure to him.
 * Expert Combatant: Octavius can engage a single opponent, like Spider-Man, or multiple opponents with the arms while performing a completely separate task, such as constructing a machine.

Weapons

 * Doctor Octopus' Tentacles: Octavius engineered mechanical limbs with nanowires connected to his spinal column to help him control fusion reaction in his experiments. They were permanently fused to his body in a lab accident, which also destroyed the inhibitor chip that was designed to prevent the arms' artificial intelligence from affecting his brain. The AI remained in control of Octavius' brain until Spider-Man engineered a replacement inhibitor chip using a Stark Industries Fabricator.
 * Neural Inhibitor Chip: This unit kept the tentacles' AI from affecting Octavius' brain. Spider-Man provided him with a new chip to restore his higher brain function.
