No assistance from anything or anyone meaning,,,,,? If your talking about just pitting both of them in a room with just Vaders use of the force and whatever weapons Dooms armor has at its disposal,,,,,I think Doom would pretty much fry him fairly quickly. The force is strong, but i've never witnessed a Jedi instantly killing somebody. It takes some amount of time whether it being minutes or even 30 seconds. Doom doesnt need that kind of time. I also seriously doubt that the mind tricks would work either.
Id have to go for Doom.
In the future of the earth (not sure if it is a real future or an alternate future), there are no humans left alive, and earth has been colonised by aliens. The only record they have of humanity is a recording from the supreme ruler of earth, (Dr Doom). So he does win in the end, even in the marvel universe.
vader could deflect the bolt with his lightsaber(assuming he has it) or even grip it with telekinesis and throw it into the wall,
i dont know too much about doc doom but if were talking about vader with the full use of sith powers powers from the books and comics, and not just the movies then my moneys definately on Vader
well, thats why you make that assumption, you dont know much about Doom. thats understandable.
Doctor Doom does just about anything he wants. tricks Mephisto(marvel's equivalent to the devil), steals a nearly omnipotent being's powers(Beyonder), is runner up for the title of Sorcerer Supreme(held by Dr. Strange...but i dont think he will be relinquishing it anytime soon though...ok, ever) [and also, sorcerery runs in his blood, his mother was a witch], cheated death by transferring his brain into another body, is super smart(everything he has was made by his own hands) and i believe he was once omnipotent for a short while, but i could be wrong there(with the Cosmic Cube...?). His determination is what keeps him going, his determination is unmatched by any character.
Give him 10 minutes(no, not even...maybe 6 or 7) and he'll figure not only how to take out Vader, but then the Emporer, and then become leader of the Imperial Empire, and take over the rest of the Star Wars universe. he'll also crush the Rebellion.
Well, seeing as Vader depends on a life support system, i dont see how he is winning against a fully-capable opponent like Doom.
Also, Doom has fought, and beaten, all kinds of telepaths before. they are nothing new to him. Experience man!
how many things on that list i wrote has Vader done? none? wow. oh, no, wait i think im wrong...Vader has cheated death right? the life support system, i remember.
I cant imagine Doom with his hands on lightsaber technology...oh man, imagine the possibilities
