Overview
Shedinja, known in Japan as Nukenin , is a Pokémon species in Nintendo and Game Freak's Pokémon media franchise, and an evolved form of the Pokémon Nincada. First introduced in the 2002 video games Pokémon Ruby and Sapphire, it is a Bug and Ghost-type Pokémon that comes into existence upon Nincada evolving into another Pokémon Ninjask when its owner does not have a full team. It has exactly 1 HP and an ability called Wonder Guard, ensuring that only "super effective" types hurt it, but any damage it takes knocks it out.
