Halo's Master Chief is a top-of-the-line super soldier. The guy is basically Captain America in an Iron Man suit that's named after Thor's hammer. Approval for The Avengers Initiative anyone? So that got me thinking, who would actually have a chance of victory going toe to toe with him? That MJOLNIR battle armor is going to be pretty hard to counter. But here are four characters I think would actually have a chance to defeat Master Chief in a full-fledged knockdown-dragout.
Though some people would say that Batman's Marvel equivalent is Iron Man, I think that Black Panther actually fits the bill much better. The guy has intense combat training, superior intelligence, and a vibranium-laced suit. MJOLNIR battle armor notwithstanding, if it came down to pitched battle between these two titans, Master Chief is basically doomed.
Villain of [The Hobbit: The Desolation of Smaug](tag:512310), Smaug could easily defeat Master Chief single-handedly. The guy's a DRAGON for goodness' sake! As long as he patches that little hole in his own armor, he could fry Master Chief to a crisp before he knew what hit him. I mean sure Master Chief's armor can withstand small arms fire, but a powerful continuous blast of flame would be devastating, even to him. His suit is tough, but it's not invincible. The guy really can get hurt, and if he goes up against Smaug, he's sure to get injured if not worse...
Darkseid is a match for almost any character in the DC Universe. He can only be challenged by Orion, Doomsday, and Superman. But the guy is absolutely lethal. As in he could crush Batman into a tiny cube with pointy ears and not even break a sweat. And if Darkseid can put that kind of whooping on the Dark Knight, I'm pretty sure he could handle a Captain America knockoff in an Iron Man suit that's named for Thor's hammer.
The ultimate opponent no matter who he is fighting, Yoda is. Easily defeat this little pointy-eared green man Master Chief would not. Often touted as the greatest swordsman in the entire history of the Star Wars' Jedi Order, Yoda is. No match for Yoda’s skill with a lightsaber would Master Chief’s futuristic armor be.
