Rapidash is a horse-like, quadrupedal Pokémon with black hooves and a cream-colored body. It has a horn on its forehead, reminiscent of a unicorn. It has red eyes that are proportionally smaller and different in design than those of its pre-evolution. Like Ponyta, Rapidash has various red and orange flames streaming from certain spots on its body. However, Rapidash's flames are different in shape and location on the body — the flames at the tops of Ponyta's legs have vanished and there are now flames on the ankles. Also, Rapidash's 'tail'-flame now streams from its back, and its 'mane' flame is much longer.
Rapidash has an incredibly diverse physical movepool, due to its aggressive outline.
