Clayton (Japanese: キジュウロウ Kijūrō) is a character of the day in Short and To the Punch!.
Clayton and his Mr. Mime, after traveling through many regions to perfect their fist techniques, now lives in an isolated area seeing as the area is suitable for their training. After seeing Ash's Buizel's bravery, he asks it to a battle which his Mr. Mime easily wins. Afterwards he teaches Ash and Buizel on how to increase the speed and power of their punches which in Buizel's case would lead to learning Ice Punch. After Ash and Buizel trains, Clayton is asked to another battle. This time, Buizel was able to defeat his Mr. Mime with the help of the activation of Swift Swim and its newly learned move.
Clayton has a strange quirk in which he runs his words together, such as "Pokéner" (Pokémon Trainer), "battover" (battle is over), "unbegood" (unbelievably good), "nowo" (no worries) and "secplea" (seconds, please). He even dubbed Ash and his friends with abbreviated nicknames: Ash and his Pokémon as AshPika (Ash and Pikachu; Japanese: SatoPika) and AshBui (Ash and Buizel; Japanese: SatoBuoy), Dawn and her Piplup as "DawnPip" (Dawn and Piplup; Japanese: HikaPoca), and Brock as "BroBree" (Brock the Breeder; Japanese: TakeBree).
