Ash's Smashing Adventure

Ash's Smashing Adventure (known in Japan as Satoshi no Dairantō (Japanese: サトシの大乱闘, Hepburn: Satoshi no Dairantō, lit.: "Satoshi's Great Fray")) is a Japanese anime series that serves as both a spin-off of the Pokémon anime AND an adaptation of the Super Smash Bros. video game series.

Characters

 * Ash Ketchum (Rica Matsumoto (Japanese); Sarah Natochenny (English)) (1): The main protagonist; a ten-year-old Pokémon trainer from Pallet Town who became licensed on his tenth birthday. The next before obtaining his first Pokémon, Ash accidentally destroyed his alarm clock, causing him to sleep in and miss out on all the starter Pokémon (Bulbasaur, Charmander, and Squirtle), so his mentor, Professor Oak, gave him Pikachu as a starter. Ash can be reckless, incompetent, dimwitted, careless, clumsy, and somewhat childish at times, but matured as the series continued.
 * Butterfree (Rikako Aikawa) (1): Ash's first captured Pokémon; Butterfree was originally captured as a Caterpie in Viridian Forest. As Caterpie, it seemed to be attracted to Misty. It later evolved into Metapod after defeating Team Rocket and again into Butterfree after being rescued from a Beedrill horde.
 * Pidgeotto (Megumi Hayashibara) (1): Pidgeotto was originally captured in Viridian Forest.
 * Pikachu (Ikue Ohtani) (1): The main Pokémon protagonist; Ash's starter Pokémon. Pikachu was chosen by Ash after all the starter Pokémon were taken. Pikachu hated Ash at first, but they became best friends after saving each other from a violent Spearow flock. He hates being confined in his Poké Ball, so he spends his journey traveling by Ash's side.
 * Misty (Mayumi Iizuka (Japanese); Michele Knotz (English)) (1): Misty first met Ash after fishing him and his Pikachu out of the water. They borrowed her bike to escape a violent Spearow flock and accidentally destroyed it along the way, prompting Misty to travel with Ash. She hates bug Pokémon (including Ash's Caterpie and a wild Weedle).
 * Goldeen (Ikue Ohtani (Japanese); Rachel Lillis (English)) (1): Misty first used Goldeen against Team Rocket, but due to its uselessness on land, it was quickly recalled.
