Jaws from "The Spy Who Loved Me" and "Moonraker" vs Gregor Clegane, The Mountain That Rides, from "A Game Of Thrones/ASOIAF."

Unarmed and unarmored, but Jaws gets his teeth (part of his body, arguably).

Specify your answer for either book or television Clegane, or both, as you choose, assuming it even makes a difference in the outcome.

(This is living Clegane, not zombified Clegane.)
