That's some good logic

It all depends on the limitations of Nathan Hale's Telekenetic powers he recieves at the end of R2. Other than distance being an issue, it seems that he could destroy anything he wanted to.

Its tough but I will say Hale, just for those powers. If it was before that part it would have eaasily been MC.

This^

Only the multiplayer to be honest.  Is this "wrist bomb" thing the only super power he gets?

honestly...if we are going to accept those fairly weak telepathic powers, then we should take into account the ending of resistance 2. nathan hale is probably dead. if he isnt dead, hes probably near dead. if he isnt near dead, then hes brain damaged or too mentally unstable and weak to provide any sort of challenge for master chief.

His speed and strength are greater than a normal humans though the game never states the limits of his abilities. He also has a wealing factor, this healing factor is one of the main reasons the chimera are so damn hard to kill.

You have proof? The ending showed him getting shot, never mentioned if he died from it. Hale had powers of his own, he absorbed Daedalus's abilities at the end so who says that sot to the head could have killed him.

so you choose option 4....

Master Chief would stomp all over Nathan Hale.  It wouldn't even be fair.

I haven't played Halo enough to see how Master Chief is, but Hale isn't anything special but a random soldier except he gets the special powers at the end of R2.
