Misdreavus, the Screech Pokémon. Misdreavus are extremely mischievous and like to cry out at night just to startle people.
– Ash’s Pokedex
Misdreavus’s claim to fame is that it’s the first pure Ghost type to be introduced, as well as being the only Ghost type in Gen II. Its Pokedex number is 200. Its Pokedex entries say it feeds on people’s fears and uses that as energy. Despite that though, I find Misdreavus to be pretty cute by design.
Even though it’s the Screech Pokemon, it can only learn Screech by breeding. It can learn a few other sound-based moves by level-up though, most notably Astonish and Perish Song.
Stat-wise, it’s got good Sp Attack, Sp Def, and Speed.
