You don't need it, but it's good to.
Nincada evolves into two separate Pokemon; Ninjask and Shedinja. To get both you must have at least one empty slot in your party. If you don't have a spare slot, then Nincada will only evolve into Ninjask.
This happens at level 20, so be prepared.
You can't exactly evolve a Nincada into a Shedinja. Instead you will have to level up a Nincada to level 20, and then let it evolve with at least one empty spot in your party and depending on the game version, you have to fulfil certain requirements (Generation III has none, but Generation IV requires at least one Poké Ball in your inventory. This Poké Ball MUST be a basic one, it cannot be something like a Great Ball or Master Ball.) If you meet the requirements, you will have a Ninjask at level 20, as well as a Shedinja at the same level with the same moveset as the Nincada had before it leveled up.
The Pokemon Ninjask naturally evolves from a Nincada at level 20. However, if the player has an empty slot in their party and an extra Pokeball in their bag, Nincada will instead evolve into Shedinja.
In Pokémon Mysery Dungeon: Red Rescue Team, you will first need to have only Haunter in your rescue party in order for it to evolve and then you will need to head to Luminous Cave and as long as you have the Link Cable item in your bag then Haunter will evolve.
The 292nd Pokemon in Pokemon emerald is Shedinja. Ways to obtain this Pokemon in Pokemon emerald: You need to get a nincada, to get nincada you must go to route 116, find it and catch it in a patch of grass, however it is an uncommon Pokemon, so it may take some time. After you manage nincada raise it to level 19(daycare recommended) have it last in your party, give it a poke'ball and have 1(one) empty space in your party, then level it up(rarecandy or epx from battle) then you will get Shedinja. (this is the only way to get shedinja in emerald unless you get it in a trade) HOPE THIS HELPS
The way to get shedinja is first you need a nincada they are not rare seriosly you can fin them in rusboro city.After you catch it make you only have 4 pokemons in your party so two slots should be empty but after you get nincada you should have five pokemons in your party and one empty slot.Train you nincada to level.20 after you do thet look in you r party and look at the 6th slot in your party and there it is the shedinja.This is true i am not joking.i am a good person and thanks for reading hope it helps. -- OMG THIS ACTUALLY WORKS. it is so surprising. this Pokemon (shedinja) only has 1 hp but the only way you can hurt it is by hitting a super effective hit becasue of it's special ability of wonder guard. ( so like if you have a fire Pokemon a water hit would be super effective). You can also posion it to kill it. this is surprisingly simple but really effective when the foe cant even touch you. O M G. ty to the person above me. -Brock 1235
it evolves into ninjask/shedninja. (you can only get shedninja if you leave a slot open in your party when you have nincada.)
First of all you need only 5 Pokemon in your party (because Nincada evolves into Ninjask, and you get a Shedinja after that) and secondly you need at least one pokeball and you should get it.
You can't exactly evolve a Nincada into a Shedinja. Instead you will have to level up a Nincada to level 20, and then let it evolve with at least one empty spot in your party and depending on the game version, you have to fulfil certain requirements (Generation III has none, but Generation IV requires at least one Poké Ball in your inventory. This Poké Ball MUST be a basic one, it cannot be something like a Great Ball or Master Ball.) If you meet the requirements, you will have a Ninjask at level 20, as well as a Shedinja at the same level with the same moveset as the Nincada had before it leveled up.
In Pokémon Mysery Dungeon: Red Rescue Team, you will need to take a Level 20 Nincada with you to the Luminous Cave and make sure that it is the only Pokémon that is in your party and then it will evolve into Ninjask and as a result of Nincada's evolution to Ninjask, a Pokémon called Shedinja will also additionaly be created at the same time.
You need to have a free slot in your party (have with you only 5 pokémon) and a Poké Ball in your bag.
The Pokemon Ninjask naturally evolves from a Nincada at level 20. However, if the player has an empty slot in their party and an extra Pokeball in their bag, Nincada will instead evolve into Shedinja.
You can only get Shedinja if you have and extra space in your party and an extra pokeball when Nincada evolves into Ninjask. It is a "special" or "castoff" evolution.
to catch shedinja, you must evolve it from a nincada. when it evolves at level 20-i think, have an empty space in your Pokemon party. if you do not, nicada will only evolve into ninjask. so, if you havbe an empty space in your party, you get ninjask and shedinja. so, its kinda like 2 for the price of 1! heres an easier perspective: nincada-lv 20=ninjask+empty slot in party=ninjask and shedinja. hope i helped u!
to get wonder guard, you have to get only 5 Pokemon in your party including nincada. then make nincada evolve to ninjask in level 20 then make sure you have an extra pokeball in your bag then after that look in the empty space in your party then pooof!!!!! its a shedinja with WONDER GUARD!!!!! enjoy!!!
First catch nincada Then leave an open place in your Pokemon (only have five with you) have an empty pokeball train nincada and evolve him That should do it
You must evolve a nincada by leveling it to level 20, though nincada can only be caught via the bug catching contest.
The only way to get NINJASK is to get a nincada near rubusto city and evolve it!
