Master Chief

The haloid video gives master chief too much credit; samus would have taken him out alot easier.

Though I would like Master Chief to win, Samus with her weapons will kick ass.

ITT: a Roman phalanx goes up against a fully-armed US Marine.

I mean, that's basically what it's like. Samus's tech is essentially that much more advanced.

Samus can lock on to her enemies, allowing her to dodge attacks and what not

you did watch that right? thats Linda not John (Master Chief). The female spartan. The one who is actually way, way stronger then Master Chief in everyway. John's only benefit was that I think he was a touch smarter if I remember from the books.

if you read the books, yes. But whats stated is false. Samus is way better trained.
