This is a fight I've wanted ScrewAttack's DEATH BATTLE! series to take on for a long time. If you don't know what the series is they basically pit different characters, generally from video games and movies, in a fight to see who would win. The fights are actually animated and are generally pretty well done. They use canonical evidence to justify their final outcomes. They've covered match-ups fanboys have argued about for years such as Godzilla vs. Gamera, Goku vs. Superman, and Mario vs. Sonic

So who do you think would win in a hypothetical fight to the death between bounty hunter Samus Aran and UNSC SPARTAN-II Master Chief.
If you want a reason for them to fight let's say Samus is contracted to kill Master Chief.
One thing to keep in mind is their physical size.
Master Chief is 7'2" 2.18 meters and 995lbs 451.3kg (In his suit)
Samus Aran is 6'3" 1.90 meters and 198lbs 89.9kg (Outside of suit) -- So in her suit you can add a little height and a lot of weight.
