7. Shedinja
As a kid, learning about Shedinja was one of the first moments when Pokémon’s scary ghost lore finally clicked in my head. Shedinja isn’t exactly an evolution of Nincada, but it will appear in your party if Nincada evolves into Ninjask and you have an open slot in your party and a Poke Ball in your bag. Shedinja is the discarded shell left behind after this evolution, and despite not moving, breathing, or showing any signs of life, it is truly alive. It only has one HP, but its Wonder Guard ability protects it from attacks that aren’t super effective. This lifeless husk is fully aware but unable to do anything other than battle, and that’s horrifying.
