I hate being the one who has to point this out, but it just niggles at me when I see things that are wrong, granted I may be wrong myself and you may know of an alternative name "doctor octagon", but I was always familiar with "Doc Ock"/"Doctor Octopus"/"Doctor Octavious" as the correct names for this particular character

They appear in the comics in the reverse order, but I was considering the possibility of "Doc Ock" being mistaken for being short of "Doctor Octagon"...
