Throh is a humanoid Pokémon dressed in a gi, a traditional training and contest uniform among many martial arts. Its head is red and has very large eyebrows. It is shorter than Sawk, and has 3 toes that make a triangle shape.
Throh is a Fighting-type Pokémon with a bulky body, red, rocky skin, and seemingly wearing a white and black martial arts outfit. Its head is round, with a “Y”-shaped black feature over its eyes and nose. The collar of its outfit is rimmed in black, and the sleeves sport a crisscrossed pattern. Throh’s hands are red with three bulbous, gecko-like fingers. It has a black, martial-arts style belt, and its white “pants” have black patches on the knees. Its feet have three digits. Its power increases when its belt is tied. Wild ones can create their own belts. Throh have a tendency to throw around larger opponents. They live in herds of around five Pokémon. It creates its own belt by weaving vines.
Throh's English name was originally going to be 'Rawkem', but was changed late in the process of English localization as a result of possible copyright infringement. Throh's counterpart (Sawk) was to have the English name 'Sawkem' (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.
Being one of the few all-male Pokémon species, Throh is unable to breed without the assistance of a Ditto.
