Doctor Octopus (Otto Octavius) is a fictional character appearing in American comic books published by Marvel Comics. A highly intelligent mad scientist, Doctor Octopus is typically portrayed as a stocky, myopic man who utilizes four powerful, mechanical appendages, and is a prominent enemy and ally of the superhero Spider-Man, respectively as Doctor Octopus and the Superior Spider-Man.
His first brief appearance as the Superior Spider-Man was in Daredevil vol. 3 #21 (December 2012) and his first full appearance of the same character was in Avenging Spider-Man #15.1 (Dec. 2012). Though historically portrayed as a supervillain, some depictions of him in the 2000s have indicated that he harbors more noble and honorable character traits, including those seen in the film Spider-Man 2, in the action-adventure video game Marvel's Spider-Man, and in the Superior Spider-Man comic book series. In the mainstream comics universe, Octavius has been recently portrayed as struggling to redeem himself, first as the antihero the Superior Octopus, before reclaiming the title of the Superior Spider-Man.
The character has appeared in numerous Spider-Man animations and video games, and is portrayed by Alfred Molina in the 2004 film Spider-Man 2. In 2009, Octavius (as Doctor Octopus) was ranked as IGN's 28th Greatest Comic Book Villain of All Time. 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." IGN rated him as the greatest enemy of Spider-Man.
