- Base-Breaking Character: Many fans, at least those of a traditional kind, don't care for Slott's reimagining of Octopus as Spider-Man's Anti-Hero Substitute. As they point out classic Dr. Octopus never showed any capacity for good being a thug-in-a-lab-coat for most of his history, and it leaves Spider-Man's rogue gallery short of one of his most iconic villains, others point out Doc Ock throughout his long history, has had several pet the dog moments, such as attempting to save the life of his old flame from AIDS, teaming up with Spider-Man to defeat Luke Carlyle and saving civilian lives (While leaving Spidey to die naturally), and even the Ditko-Lee era had Ock treat Aunt May and Betty Brant civilly despite them being hostages. Additionally supporters of Doc Ock's Superior phase, cite the hilarity of Ock as Spider-Man, Awesome Ego, Super-Villain approaches to heroism and occasional Extremist was right moments to be entertaining as a protagonist, while the first group insist that Octopus being scum was important for Spider-Man's most important classic stories — The Master Planner, The Sinister Six, The Owl/Octopus War.
- Can't Un-Hear It: Considering that Spider-Man 2 has one of the best portrayals of him, you should read his lines in Alfred Molina's voice.
- Complete Monster: While typically written as charismatic with plenty of redeeming qualities of his own, these incarnations of the multi-armed doc prove to be nothing but pure, undiluted evil.
- Spider-Man: Global War: Doctor Otto Octavius, aka Doctor Octopus himself, starts his plot to Take Over the World by stealing parts of a secret Department of Defense program which will allow missiles to be launched without revealing the location, Doc Ock uses a rocket to cause an EMP to hit much of the Western Hemisphere, something in itself likely causing countless deaths. This is only for starters. Doc Ock plans to use a second rocket—nuclear-tippled—to strike near the capital of Latveria. Doc Ock has been secretly aiding Latveria's own nuclear program, and, with the help of a Latverian spy whose family he had kidnapped, had been feeding Doctor Doom's paranoia. Once the second rocket strikes near the Latverian capital, Doc Ock predicts Doom—not being able to discover from where the rocket was launched—will respond by firing nukes in all directions. The rest of the world—which, thanks to the EMP, won't be able to communicate with Doom—will have to counter-attack. Doom will lose, but the rest of the world will be devastated. From this, Doc Ock—having taken refuge underground—will emerge as the savior of mankind and its ruler. This version of Doctor Octopus was willing to cause tens of millions of deaths just so he could rule the world.
- Spider-Man: Noir: Otto Octavius, aka Doctor Octopus, stands in stark contrast to his occasionally-noble 616 counterpart. Born a cripple in South Africa, Otto grew up jealous of the healthy, able-bodied Africans that he grew up around, which developed into a violent hatred for the black race in general. Wishing to gain the approval of Heinrich Himmler and the Nazi party, Otto has innocent black people kidnapped off the streets and performs horrifying, inhumane experiments on them. These experiments result in his victims, such as Peter's friend Robbie Robertson, being reduced to drooling, mindless vegetables that are meant to be used for slave labor. And Otto isn't above casual murder, as shown by him brutally stabbing his ally Crime Master to death when he tried to have Otto's victims burnt to cover their tracks, viewing his actions as wasting his research.
- Amazing Spider-Man: Doctor Otto Octavius lacks his final product's much more tragic, complex characterization, presented in this draft script as a complete psychopath driven by his ego. Having murdered Richard and Mary Parker years ago for hiding the image refractor from him so as to prevent the completion of Octavius's dangerous fusion machine, Octavius takes their son Peter under his wing and manipulates the young man into the handing the refractor over before trying to kill him as well. After having his metallic tentacles fused with his torso, Octavius uses them kill his way out of a hospital and goes on a rampage through New York City, murdering several people and endangering dozens more. Octavius hopes to ally with foreign powers to complete his fusion reactor, fully willing to then hand it over to terrorists to use as a WMD so long as he gets to see it in use, and raids the wedding of Harry Osborn to obtain the final missing component to the machine, threatening the hundreds of guests with death if he doesn't get what he wants.
- Fashion-Victim Villain: His original outfit, while iconic, combines a bad haircut, garish green-and-yellow color scheme, and portly build. Though it's such an iconic look and fitting to his personality.
- Jerkass Woobie: Dan Slott's interpretation during the latter part of the Big Time run and the entirety of Superior Spider-Man.
- Magnificent Bastard:
- The Spectacular Spider-Man: Dr. Otto Octavius was once the meek, milquetoast assistant to Norman Osborn, and created several supervillains with his scientific genius, but upon nearly dying in a lab accident and having his arms welded to him, becomes the genius, diabolical "Dr. Octopus." After his initial defeat by Spider-Man, Octopus grows smarter and more resourceful, creating the villainous team-up of "the Sinister Six", using them to beat Spider-Man to such a point that the hero flees for his life. A gentleman who is genuinely friendly with his fellow villains and willing to allow safe passage to innocent bystanders, Octopus takes over a chunk of New York's criminal underworld as the "Master Planner" from the luxury of a mental hospital he has manipulated himself into by pretending to be redeemed. Octopus's master plan is to take over the computer systems of every piece of technology in the world, and succeeds in doing so to Manhattan before being stopped by Spider-Man. A mastermind so brilliant that he ran rings around every other villain in the series at least once, Dr. Octopus is one of Spider-Man's greatest, most intelligent foes.
- Spider-Man: Faking a HeelFace Turn to present a heroic face to the world, Dr. Otto Octavius plots to force humanity's advancement through the symbiotes. Using proxy criminals to create distractions, Octavius steals vital technology to blanket New York in fog and unleash the symbiotes. Mastering the symbiotes and even keeping the unstable Carnage on a leash, Octavius manages to infest much of New York, nearly pulling off his plan right under Spider-Man's nose while escaping suspicion.
- Memetic Mutation: "Doctor Octagonapus Bluah!"
- My Real Daddy: He's an iconic villain by Ditko and Lee without a question, but the more common idea of Dr. Octopus in modern versions and adaptations: the idea of Dr. Octopus being Peter's Shadow Archetype and having a sympathetic and tragic backstory was entirely created by Tom DeFalco who also established briefly Otto and Peter potentially being "science bros". These aspects filtered in Spider-Man 2, Spider-Man (PS4), Superior Spider-Man.
YMMV / Doctor Octopus
