Sunfire has the ability to form a psionic force field while using his plasma as protection from heat and radiation, both that of his own generation and that from outside sources making pyro not even a challenge.

Round 1 Avengers, simple fact the Hulk. Round 2 still simple fact the Hulk, iron man could use 10 hrs prep as hes a scientist and the tech in mavel universe way surpasses that of the DC. Batman is a detective and 10hrs collecting clues isnt going to help. And yet again round 3 would go to the avengers as J.L would have 1 hell of a time with the Enchantress.

Kain Marko would win as Goku could never really hurt him. Juggernauts weakness isnt one that can be exploited for his defeat but to hinder him and once jugernaut got his hands on him he'd rip him limb from limb.

Doom would easily take over the Star Wars universe, without any prep time. His suit would rivel any spaceship they threw at him as the only ones that could really hurt him are way to big and wouldnt be able the maneuver fast enough to hit him. He can fly in space which ive never seen a jedi do whithout the aid of a craft. The forcefield on Doom powersuit would be able to deflect any blaster fire, wookie X-bow, lightsaber strike, jedi force push, or dark lighnning. The only way Star Wars could win is if they were able to use the Sun Crusher in the solar system Doom happened to be in, as its capable of causing a star to collapse and go supernova, but it was destroyed at the Battle of the Maw Installation

And if Doom does have prep time, then Stars wars has no chance cuz Doom would have access to find out any and everything about the star wars universe threw the empire, the rebels, or the new republic database depenging on when it happens.

Im going to place my bet oh Magnus. Thor could never strike him with Mjölnir as his magnetic shield would prevent this. Thor getting fustrated with this would then try lightnning, which as indicated by battles with Storm will only increase his power making him Electromagneto. Once Magneto stripps Thor of Mjölnir, he could no longer fly opening him up to any and all arieal attacks further Magneto could then create a magnetic forcefield around Thor and drop him off at the sun or perhaps a blackhole might be need to dispose of him.
