A battle of 2 futuristic space warriors with advanced weaponry and vehicles but who would win in the end? Being a Nintendo and Metroid fanboy, I would say Samus but this isn't who I think would win it's who you think would win. But just note that each competitor is allowed vehicles (Samus in her spaceship and Master Chief in his multitude of vehicles). They are also allowed all weapons that they have ever had throughout all their games. Now, who do you think would win?
