...wth is a Nathan Hale?

This made me lol.

On topic though I think the Master Chief takes this one.

Depends,

End of R2 Hale > Master Chief

R:FoM-R2 Hale < Master Chief

But considering Hale is only better at the end of R2,

Master Chief wins in my book

Wow this is a really good match up. Although I'm going Hale because of his regenerative properties and enhanced vision and telekinesis.

While Chief may be an excellent fighter, both use guns as the main form of attack (other than R2's ending) but i would put Hale above that too because he gets Chimera vision which can heat seek giving him another edge

I forgot about those powers

This

How are the weak?   Those powers destroy anything that is in his sights,  there was no limitation of this other than the distance it was effective.  

BTW the ending with Hale dying probably isnt what really happened.  If you find some of the secret documents lying around you will find out that Capelli is prone to hallucinations.  Which is what alot of people are saying happened in the end of the 2nd one otherwise what the point in making a 3rd.   

Nathan Hale has no hops. I gotta go with the chief.

you seriously going to argue that he would hallucinate what had been a private exchange between hale and daedalus.  and that insomniac would end a game with someone imagining they killed the main character.  or that they would have a third game with hale as the main character where he has those powers. 

or that those powers which he got from mrfloaty would actually be truly powerful....eventhough hale, whom was still practically a normal human regardless of his infection, was able to defeat him. 

about as likely has Hale really having a bad acid trip, or being stuck in a mental institution in the 50s and the whole thing being his own imaginings.

besides co op, the ending (with hale dying or being seriously injured) was the only interesting part of the game.
