Shedinja

“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.”

— Pokémon Ruby

“SHEDINJA is a peculiar POKéMON. It seems to appear unsought in a POKé BALL after a NINCADA evolves. This bizarre POKéMON is entirely immobile - it doesn’t even breathe.”

— Pokémon Sapphire

“A peculiar POKéMON that floats in air even though its wings remain completely still. The inside of its body is hollow and utterly dark.”

— Pokémon Emerald
