One of the most integral themes underlying Lord of the Rings is the potential of small, unassuming, underestimated figures. No one would have picked Frodo Baggins as the hero destined to drop the Ring into Mount Doom, but he shocks the world and himself by getting the job done. Middle-earth is full of characters that defy expectations and do the impossible. Huan may appear to be a typical massive wolfhound, but he also once fought Sauron and won.
