Dayton's Chinchou (nicknamed Bright) is a water/electric-type Pokémon formerly owned by Dayton.
Dayton had a Chinchou nicknamed Bright, who was mischievous enough to electrocute Ash, who wanted to touch it. Later, Bright, along with Dayton, led the Chinchou, even after being separated from Misty, Brock and Dayton's father. Though Bright and the other Chinchou were taken by Team Rocket, they managed to defeat the trio. Upon leaving, Bright bid farewell to Dayton and joined its friends to swim across the ocean.
