Ralts is a humanoid Pokémon with a white body. It has thin arms and legs that widen toward the feet. There is a wispy extension trailing off the back of its feet, creating the overall impression of a nightgown or oversized dress. Most of its face is covered by green hair that resembles a bowl cut, but a pair of pinkish red eyes is sometimes visible. There are two flat, red horns on top of its head: a large one toward the front and a smaller one at the back.
