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.
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.
