i would have to go with samus

Samus would win

.....

but a pichu would win if he was in it

Yeah, I think Samus is kind of obvious, coming from a person who's played both series from the inside out.

I think if Samus lost her power suit, Master Chief would get distracted & Samus would win.

Samus would show her breasts and Master Chief's erection would short out his armor.

samus! and lololol @RCT's post!!

 lol kinda like the video that a user at gametrailers made

samus

why? she already has a gun with her all the time

Samus, Master Chief would run out of ammo while Samus would spam beams and missiles.

There was some video made by the same guy who made Dead Fantasy about this specific fight. It was really cool, and then they teamed together to take out a horde of baddies, and then Masterchief lost his suit, turned out to be a chick, and she and Samus made out.

It was really weird....so I guess I would say that if Samus and Masterchief fought then guys who like lesbians would be the winners.
