Shedinja's hard body doesn't move - not even a twitch. In fact, its body appears to be merely a hollow shell. It is believed that this Pokémon will steal the spirit of anyone peering into its hollow body from its back. It seems to appear unsought in a Poké Ball after a Nincada evolves. This bizarre Pokémon is entirely immobile - it doesn't even breathe. Shedninja floats in air even though its wings remain completely still. The inside of its body is hollow and utterly dark.
