This Basculin was a Water-type Pokémon owned by Cilan.
Basculin was caught temporarily by Cilan during a fake fishing competition which Team Rocket created so that they could steal as many Water-type the participants could. Cilan battled it with his Pansage which had the type advantage. After a rough battle, Cilan caught it and gave it to Team Rocket. When the Pokéballs fall into the water, a female Frillish released it to save all the Pokémon from Team Rocket.
- Basculin is the first Pokémon to be released in the Black and White saga.
