Sawk is a humanoid Pokémon with blue skin. He sports a light blue Gi, a traditional uniform for training and contests in many martial arts. He has two, three-toed feet and he has a very big, bushy, eyebrow on the left side of his face.
Sawk is a very stern, secluded Pokémon that is takes his martial arts training very seriously. He will become angered if disturbed in the midst of his training. They tend to seclude themselves in mountains and train without even stopping to rest.
Sawk's English name was originally going to be 'Sawkem', but was changed late in the process of English localization as a result of possible copyright infringement. Sawk's counterpart (Throh) was to have the English name 'Rawkem' (which, when read in Pokédex order, would read 'Rawkem Sawkem'). This is a play on the famous 80's toy franchise Rock 'Em Sock 'Em Robots. Even more of a coincidence, are the matching red and blue colors shared between the Pokémon and the game's characters.
Sawk is based on a Karate Master.
Sawk along with Throh may be based on the Ashinaga-tenaga, a pair of yokai one of which has long arms and the other has long legs with Sawk representing the longed legged of the pair.
Sawk's English name is a corruption of the word "sock", meaning to punch.
