You can't catch shedinja in the wild.
It is considered a "special" evolution of Nincada, appearing only when Nincada evolves into Ninjask, starting at level20, and there is an extra space in the player's party and the player has an extra Poké Ball. An extra Poké Ball is not necessary to obtain Shedinja in Generation III.
Shedinja does not evolve.
To get a Shedinja in Pokemon Heart Gold you must trade it from either Pokemon Ruby, Sapphire or Emerald. Jacko25
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.
If you mean Shedinja, you get it by training a Nincada to level 20 and having an empty slot in your party. The Nincada will evolve into a Ninjask and the empty slot will be filled by a Shedinja.
nincada evolves at level 20 in Ruby/Sapphire it also evolves into shedinja so you better leave space in your team
if you enter the bug catching contest several times you can catch nincada and evolve into shedinja or you could trade from emeral, ruby, saphire. this is the only possible way without hacking. hope it helped =)
you can only get it with cheats or you 'l have to evolve a ninjask
To get Shedinja you need to a Nincada. Level up your nincada, but make sure you have an empty space in your party. level up nincada to level 20 and it will evolve into ninjask. then look in your party... you will have a pokeball with shedinja in the empty space
Shedinja is the leftover Pokémon when Nincada evolves into Ninjask at level 20, if you have an extra slot in your party.
Most people find value in Shedinja because you have to go through a series of steps to get it and its one and only Ability is Wonder Guard, which allows only super effective moves to damage Shedinja. Unfortunately, Shedinja only has one Hit Point, so if one attack gets through its Ability, you'll find yourself choosing another Pokemon to battle your opponent.
shedinja's powers lack the consistency of Pokemon
Nincada evolves into Ninjask at level 20 while Nincada evolves into Shedinja when you level it up while you have space in your party and your belt.
