Spider-Man No Way Home character info : Doc Ock

Otto Octavius is a generally likable man, who is married to his loving wife, Rosie Octavius. He is the scientific idol of Peter Parker, and Peter first meets him through Harry Osborn, who is funding Octavius for Oscorp. Octavius regards intelligence as a gift that should be used to benefit mankind, and rather than working with nuclear material, he uses nuclear fusion to create a miniature electricity-generating "sun", which he manipulates with four robotic tentacles, which he describes as impervious to heat and magnetism, mounted on his back.

The tentacles have several differences from their comic book counterparts- in the comics, Octavius controlled them with dials prior to his accident, but in the movie, they are attached to his nervous system along his spinal cord and he controls them mentally from the outset. They are designed with a complex claw system allowing Octavius to manipulate objects of any size. Each claw also houses a separate camera, allowing the Doctor to see in any direction. They do not possess a large number of weapons like they do in the Ultimate Spiderman series but in several scenes in the movie, Doctor Octopus extends daggers from the tips to battle Spider-Man.

In addition, each individual tentacle has its own artificial intelligence built within it. An inhibitor chip is built into the apparatus to ensure Octavius retains control over the machines and not vice-versa. When the chip is destroyed in his accident (caused when the "sun" he creates becomes unstable, and a large "flare" from it strikes him in the back, administering a huge electric shock that fuses the tentacles' attachments to his spine), they are able to manipulate his mind and drive him to rebuild his failed fusion device. The tentacles' influence, combined with the loss of his wife Rosie and his failure, is what makes Doc Ock evil in the movie, rather than him simply becoming insane due to brain damage from the accident as he does in the comics.

Powers and abilities

Doctor Octopus has been hinted as being a low-level technopathic mutant, but no superpowers have been outrightly revealed. He is a genius in the fields of atomic physics, in which he holds a Ph. D. A brilliant engineer and inventor, he is also a superb strategist and a charismatic leader.

Due to exposure to atomic radiation, Doctor Octopus has acquired the mental ability of psychokinetic control over the four electrically powered, telescoping, prehensile, titanium-steel artificial tentacle "arms" (a degree of psychokinetic control over them that he can also exercise over vast distances even when they are not connected to him) that are attached to a stainless-steel harness encompassing his lower torso. Each of these four arms is capable of lifting several tons, provided that at least one arm is used to support his body. 

The reaction time and agility of his mechanical appendages is enhanced far beyond the range attainable for normal human musculature. The arms allow Octavius to move rapidly over any terrain and to scale vertical surfaces and ceilings. He has developed his concentration and control to the point that he can engage a single opponent, like Spider-Man, or multiple opponents with the arms while performing a completely separate, more delicate task, such as holding a cigarette or constructing a machine. While wearing the harness, the arms are powerful enough to allow Doc Ock to walk up sheer concrete walls and move quickly about. They are also used to grab items, both small and large, and as literal weapons in terms of being swung at objects and people like clubs.
