While going hands-on with Pokemon Sword and Shield during E3 2019, we discovered two new Galar Region: an Electric corgi and a Dark/Fairy imp.
Yamper: an adorable Electric Corgi
In our demo, Yamper the electric corgi had the Fairy-type move Play Rough, the Electric-type move Spark, the Dark-type move Crunch, and the Electric-type move Wild Charge. His ability was Ball Fetch, which will allow him to return the first failed PokeBall thrown in battle, so long as he’s not already holding an item. We were able to Dynamax Yamper, which caused his move set to change to Max Starfall (Fairy), Max Lightning (Electric), and Max Darkness (Dark).
