Master Chief vs. Samus Aran

Who would win in a fight? Master Chief (protagonist of Halo) or Samus Aran (protagonist of Metroid)?

Samus would pwn.

I don't care how much of a pretty cool guy Master Cheif is. Samus has been killing aliens since before he was in diapers.

let's see, Metroid Prime did something different, unique, and fun with the FPS style and Halo was the beginning of the ruination of the FPS genre... Samus all the way...
