Yamper

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

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.

Origin
Yamper is based on a Pembroke Welsh Corgi puppy.

Etymology
