Yamper (ワンパチ Wanpachi) is an Electric-type Pokémon introduced in Generation VIII. It evolves into Boltund at level 25.

Biology

Physiology

Yamper is based on the Corgi, a breed commonly attributed to the UK (Welsh Corgis, the royal Corgis). It shares the chubby body and short legs with the Corgi, but its face more resembles the Boston Terrier. Its underbelly and paws are white, while its top half is light tan. It has a small, lightning-bolt shaped tail. The insides of its ears are green and yellow, as are its eyes. It has a large patch of yellow fur around its neck. It has two small, visible fangs on the bottom of its mouth.

Behavior

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 follows and obeys people only because it wants treats, according to its Shield Dex entry. However, this doesn't affect its popularity in Galar as shepherd dogs.

Origin

Yamper is based on a Pembroke Welsh Corgi puppy. It may also be based on 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.

Etymology

Yamper might come from yap, a dog noise, scamper, to run around, and ampere, a measurement of electricity.
