==Biology==
Shedinja is a resembling a cicada's shed exoskeleton. Most of its body is light brown, but the abdomen is gray. It has four protrusions on its underside instead of legs; the top pair is brown, while the lower is gray. There are round protrusions on the side of its head with narrow slits for eyes. Two lines encircle its abdomen and a white crescent-shaped halo floats above its head. On its back is a pair of tattered wings divided into three wingtips. A hole between its wings reveals that its body is completely hollow and dark, as it possesses no internal organs.

==Trivia==
* From Generation IV onwards, a basic (a requirement for evolution) is removed from the Bag upon evolution to produce a Shedinja. In Generation III, Shedinja instead copied the ball Nincada was in; this is one of only two legitimate ways to obtain Shedinja in a non-standard Poké Ball until Generation VIII, where Shedinja can be caught in Max Raid Battles or transferred from Pokémon GO. 
** The other option is to catch a Nincada in via the Bug Catching Contest in a Sport Ball and evolve it in , or . Because the Sport Ball is not coded to exist in Diamond, Pearl, and Platinum, it copies the Ball to the Shedinja without reassigning it to have a basic Poké Ball. This effect would also apply to any other Balls that are considered "out-of-bounds" by these games, such as Apricorn Balls, but in HeartGold and SoulSilver, Nincada is only obtainable in the wild from the Bug Catching Contest, in which only Sport Balls can be used.
