I have yet to see a bigger Omega Red fan than me on this forum, but hes not beating DD. Why? Because DD would adapt to the Phermones then they would be ineffective.
Red does have the Death Factor, but how long would it take for him to drain for Doomsday to even start to get weak? How long would it take for DD to adapt to the drain?
Ive argued in the past that Red could have a change against Hulk, but those things i mentioned would work better on Hulk that it would DD. Plus DD starts at a much higher level than Hulk. Red doesnt stand much of a chance here.🙁
