You level up a Nincada to level 20,
yet at the same time having an empty space in your team (Shedinja will fill this space.)
and having a spare pokeball (only a pokeball, not a great ultra, or other kinds.)
And your Nincada will evolve into Ninjask and a Shedinja will fill up that empty space.
Wll you can have a other type of ball what I mean is Poke Great or Ultra Works the other types like Nest Love etc wont work I have my shedinja in a(n) ultra ball
Shedinja does not evolve.
shedinja's powers lack the consistency of Pokemon
Shedinja, with an HP of 1!
Shedinja does not evolve any further than its current stage.
shedinja doesnt evolve nincada evolves into ninjask and if you have room for another Pokemon and a pokeball ninjask will split in half making shedinja
Shedinja is the last evelution so no, he can't evolve.
Shedinja learns false swipe at lvl 25.
In the party you should have an open space for shedinja once your nincada evolved shedinja should appear in the open slot
No.
Shedinja will have only 1 HP at any level.
Shedinja is #292 in the national pokedex, and it is a Bug-Ghost type Pokemon.
Yes, it is in the same line of evolution. You will get a shiny Ninjask and Shedinja.
