I say Ultron or Doctor Doom
I'm sorry...no one beats Dr Doom. His intellect alone makes him one of the most dangerous mortals on earth. Couple this with the fact that he is the most powerful alchemist on earth (sorry Diablo)...combining mega-science with mega-sorcery. And he is absolutely ruthless. Extremely dangerous. And he is an extreme alpha personality.
Doom is the man.
Yea. Sometimes your able to kill 50% of the Earth's population and others you get taken away cuffed by police officers.
I have been doing the villains popularity tournament and we are really close to finishing.
Marvel and DC both have four villains each.
- Doctor Doom
- Lex Luthor/Harley Quinn (this one is still going)
Eddie Venom was always best as a villain, not the Lethal Protector anti-hero, so he'd get my vote as one of my favorites. Also, when I think a "Marvel villain" I think someone who spanned titles, so in that case I'd say: Norman Osbourne, Dr. Doom, Ultron, and Thanos.
