Nincada, the Trainee Pokémon. Nincada lives most of its life inside the earth and uses its sharp claws to tap into tree roots extracting nutrients and moisture.
– Ash’s Pokedex
Nincada is interesting in that it can simultaneously evolve into two Pokemon, Shedinja and Ninjask; if there’s space in the party and a Pokeball in the bag when Nincada evolves into Ninjask, Shedinja, the shed shell, will appear. Nincada is one of the 2 Bug/Ground Pokemon, the other being Sand Cloak Wormadam.
Other than that, Nincada isn’t all that notable. Its highest stat is Defense. It’s rather slow, despite the fact that Ninjask is crazy fast.
