Shedinja uses the Wonder Guard Ability. This Ability prevents all direct-attack damage from Physical and Special Attacks unless the move is Super Effective against it. Wonder Guard does not prevent damage from weather effects, entry hazards, damage from Poison or a Burn, or self-inflicted damage due to being Confused.
Nincada can evolve into a Ninjask starting at Level 20. At the time Nincada evolves into Ninajsk, if you have at least one Poké Ball in your inventory and have five Pokémon or less in your party, you'll also obtain Nincada's other form: Shedinja, with the same moves that your Ninjask has when it evolved, including any moves that Ninjask learns on the level that it evolved.
Shedinja is in the Mineral Egg Group, and its Egg takes approximately 3,840 Steps to hatch. It takes Shedinja 600,000 Experience Points to reach Level 100.
Shedinja takes on the appearance of a bug Pokémon's shell shedding, with a halo-like ring above its head.
Unlike Nincada and Ninjask, Shedinja is a Genderless Pokémon.
Shedinja appears at Secret Storage 19, Endless Level 33, Forever Level 33 and Mr. Who's Den in Pokémon Trozei!.
Shedinja can only be obtained by evolving a Nincada in the first Mystery Dungeon game. In Explorers of Time, Explorers of Darkness and Explorers of Sky, Shedinja appears at the first 19 floors of Mt. Travail. Shedinja also appears at Sky Summit PTC8 1-4F, PTC9 1F-5F and PTS 1F-5F in Explorers of Sky. Shedinja is exclusive to Blazing Adventure Squad in Mystery Dungeon 3, appearing at Weird Mountain 21F-23F.
In all the Mystery Dungeon Games, only an empty slot in your party is needed to obtain Shedinja when it evolves.
Shedinja appears at Lila Forest in Pokémon Ranger. This is its only appearance in the Pokémon Ranger series to date, as Shedinja does not appear in either of the two sequels.
Shedinja can be found at Misty Edgewater Forest 2-2 in Pokémon Rumble Blast after completing the game.
Trading Card Game
Shedinja appears in five sets. It is listed as a Rare card in the EX Dragon, EX Deoxys, Legends Awakened, Supreme Victors and Dragons Exalted sets.
A Shedinja was being used by the power-hungry Colonel Hansen in the episodes The Princess And The Togepi! and the next episode A Togepi Mirage!, which saw Misty's Togepi evolve into a Togetic. Ash & Company were having a hard time dealing with what seemed to be an unbeatable defense until May's Torchic used a Fire-Type move to repulse it.
Other trainers have also used a Shedinja in a Pokémon Contest on a few occasions.
Shedinja has yet to appear in any of the movies as of writing.
Shedinja's Manga info is unknown at this time.
Shedinja resides in the PU tier of competitive battling. With a very unique ability in Wonder Guard, Shedinja makes for an interesting case of a Pokémon as it can avoid any attack that is not super effective against it. This allows for it to take on numerous threats in the tier, such as Simipour, Raichu, and Regice. Shedinja's ability to as an effective pivot due to its access to Baton Pass and ability to only be damaged by super effective attacks. However, Shedinja has only 1 HP and has some weaknesses to common attacking types in the tier. It can be easily taken out by any form of passive damage like entry hazards, Toxic, burn, Leech Seed, and weather conditions like sand. It also needs a lot of support, including entry hazard removal in Defog or Rapid Spin, but that is not as easy to pull off especially in a metagame that is focused around entry hazards.
Shedinja is also usable in the Neversed (NU) tier of competitive battling. Wonder Guard gives Shedinja the ability to shut down many threatening Pokémon in the tier, such as Ludicolo, Samurott, and Kangaskhan. It has a decent Attack stat and priority Shadow Sneak to make up for its Speed stat. With Baton Pass, Shedinja acts as a well-rounded pivot and can force lots of switches, which allows for it to take advantage and gain momentum for a team. However, Shedinja has numerous weaknesses, an atrocious 1 HP stat that cannot be invested in, and weakness to all forms of entry hazards, making it so that it needs hazard control and status absorbers to not be dead weight.
Shedinja is a viable option in the Underused (UU) tier of competitive battling. The ability to wall certain set up sweepers like Snorlax, Suicune, and Cobalion thanks to Wonder Guard makes Shedinja viable in the tier in the first place. It can run a Swords Dance set that can beat opposing Pokémon that are helpless against it or just opt for a pivot set with Baton Pass to keep momentum on the team's side. However, Shedinja is very much flawed in certain aspects, due to its weaknesses to common attacking types, entry hazards, and status moves. Therefore, it needs to have a team built around it with multiple entry hazard removers and potentially a Magic Bounce user, making it more of a niche option in UU, albeit one with a very unique niche.
