Doctor Octopus, more commonly known as Otto Octavius, is the main antagonist of the second Spider-Man Noir volume. While the character Doc Ock is naturally played as a villain, this Nazi-aligned version of said character is depicted to be an even more ruthless and sinsiterly depraved individual than his mainstream counterpart, so much so that he even lacks the same sympathetic or insecure backstory as his mainstream and movie versions respectively.
