Shedinja: catch a Nincada and train it to level 20 but make sure you have an empty space in your party and a POKEBALL(only that will work) and when it evolvesyou will get both Ninjask and Shedinja(which apears in the empty Pokeball&party space
shedinja is pretty good it is good at Pokemon that don't know these type moves :fire,fly,ghost,dark,and if something uses rollout it kills it to.
The Pokemon with the lowest HP is Shedinga. The base HP for this guy is 1, and stays that way no matter what unless you hack. It at least has the ability Wonder Guard to make up for this.
you catch a nincada then u lvl it up to lvl 20 but make sure you carry only five Pokemon with you when you do because when you hit lvl 20 nincada will evolve into ninjask and you will get shedinja free
You cannot evolve Ninjask into Shedinja. Nincada evolves into Ninjask at Level 20 at which point Shedinja will appear in your party provided you have an empty spot and you have an extra Poké Ball in your bag.
In order to beat Shedinja, you will need to attack it with a super effective move. A move that is super effective on Shedinja would be Flamethrower because it's a Fire-type attack and Shedina is part Bug-type and Fire-type attacks have an advantage over Bug-type Pokémon.
The Pokemon Shedinja has Wonderguard. You need to have an empty slot in your party. Evolve Nincada by leveling it up. When Nincada Evolves, it becomes a Ninjask. The Last Slot in your party will be a Shedinga. The Ability Wonderguard is the best, because only supereffective attacks will hit the Pokemon with Wonderguard. Status-Changing attacks will Hit Though. If You can hack a Sableye or Spiritomb with Wonderguard. It is Nearly Invincible Because Both of them are Ghost and Dark Types, which means they have no weaknesses. The only to defeat them is by using toxic or will-o-wisp, or oone one of the move which causes Burn or Poison
