Chief has been shot by regular human bullets before while he was looking at the attacker. He's not neo, he's just fast. Plasma travels slower and that's why he could dodge it.but in the destiny universe, one would only need to shoot him once or twice. Whereas he might not be able to penetrate the playing of a titan. Also, why wouldn't supers count. They're one of the three main abilities of a guardian. It's not like master chief doesn't have stuff. He would have a drop shield. My point is. Destiny is so much more technologically advanced than halo, it's ridiculous. But it doesn't matter, because neither of these characters are real, and neither will ever fight the other.
