Throh is a Fighting-type Pokémon with a bulky body, red, rocky skin, and seemingly wearing a white and black martial arts outfit. His head is round, with a "Y"-shaped black feature over his eyes and nose. The collar of his outfit is rimmed in black, and the sleeves sport a crisscrossed pattern. Throh's hands are red with three bulbous, gecko-like fingers. He has a black, martial-arts style belt, and his white "pants" have black patches on the knees. Its feet have three digits.
