After exposure to a moon stone, this Pokémon developed very sensible hearing, so it prefers to live in quieter isolated areas. It comes out at moonlight and was sometimes seen staring at the moon for long periods of time.
A very adorable-looking Pokémon. Despite this, it is rarely spotted, as it comes out during nighttime. Conspiracy theorists claim that this Pokémon came from outer space.
The Nidoking has a tail that it can swing hard enough to topple down a telephone pole. It also has a VERY bad temper, and can go on rampages if provoked hard enough.
