The only plausible theory is the Decoy Octopus one (and, by even more speculative extension, possibly Chico). He's being voiced by Sutherland just the same as Big Boss, giving more credence to the hallucination theory more than anything else -- therefore, he is NOT Skullface or Gray Fox. End of story.
