Yamper is a [Electric](https://pokee.si/types/electric)-type Pokémon, the Puppy Pokémon, number 835 (#0835) in the National Pokédex. It was introduced in Generation 8 and comes from the [Galar](https://pokee.si/guide/regions/galar) region. It is 0.3 m tall and weighs 13.5 kg.

Yamper is the Puppy Pokémon, a corgi-like Electric type that crackles with sparks when it runs and, the Pokédex says, only lends a hand with chores when treats are on offer. In Galar it is a popular herding dog.

## Lore

### Biology

Yamper is 0.3 m tall and weighs 13.5 kg. It has a brown body with a yellow fluffy collar, white paws and underside, and a yellow, bolt-shaped tail, with a heart-shaped mark on its rump. Bulbapedia says it has an organ at the base of its tail that makes electricity while it runs, but it cannot store it, so sparks fly off as it goes.

### Behaviour

Yamper cannot resist anything that moves fast and gives chase to people, other Pokémon and even vehicles. Bulbapedia says Joltik often sit on its hindquarters to feed on its static electricity.

### Habitat

The Pokédex gives no habitat. In Sword and Shield it is found on Routes 2 and 4, at Motostoke Riverbank and in Stony Wilderness, and in the Crown Tundra at Ballimere Lake.

### Powers

Yamper's Abilities are Ball Fetch, which no other Pokémon can have, or Rattled, which is hidden. It uses Nuzzle, Spark, Charge and Wild Charge for electric attacks, with Bite, Crunch and Play Rough for biting. With base Speed of only 26 it is a slow, fragile first stage.

### Name origin

Yamper may combine 'yap', 'ampere' and 'scamper'. The Japanese name is Wanpachi (ワンパチ), which may join wanwan, the Japanese bark sound, and pachipachi, a crackling sound.

### Design inspiration

Yamper looks like a Welsh corgi, the breed famously kept by Elizabeth II, who was Queen when Sword and Shield were made and released; Galar is based on the United Kingdom. Its tail takes the shape of a lightning symbol. These are fan readings.

### Evolution notes

Yamper evolves into Boltund at level 25.

### In the games

Yamper is Sonia's partner Pokémon in Sword and Shield, where it debuted; she and Yamper join the Gym Challenge with Leon but drop out. It is not available in Scarlet and Violet or Legends: Z-A.

### In the anime

Professor Cerise has a Yamper, introduced in 'Legend? Go! Friends? Go!', that tends to keep Chloe company at home. In Pokémon: Twilight Wings, Sonia's Yamper is at her home with her and Professor Magnolia.

### Fun facts

- Players saw Yamper in an E3 2019 demo before it was officially announced.
- It shares the category Puppy Pokémon with Growlithe, Lillipup, Rockruff, Fidough and Pombon.
- Its height of 0.3 m is the joint shortest of any Electric type introduced in Generation VIII.
