Yamper (ワンパチ Wanpachi) is an Electric-type Pokémon introduced in Generation VIII.


Physical Appearance

Yamper looks like Corgi from Britain.


Yamper has a habit of chasing running and moving things, ranging from humans and other Pokémon to moving vehicles.

As it can't store much electricity in its organ, this can explain its tendency to roam around with crackling electric sparks.

Yamper is based on a Pembroke Welsh Corgi puppy. It may also be base don either the Raiju, a mythical lightning beast in Japanese mythology, which is known to take the shape of a wolf or dog. It may take some inspiration from the black dog, an English myth that is known to be seen during thunderstorms.


Yamper might come from yap, a dog noise and ampere, a measurement of electricity.
