This is the first Pokémon Contest in which Ash and May have competed in costume. Ash has already participated in a Sinnoh region contest, but did not dress up.
Most rivals (excluding Gary, probably because Ash's rivalry with him has been resolved) of the main protagonists (Ash, May, and Dawn) are shown either in cameos or throughout the course of the episode: Drew, Solidad, and Harley for May; Paul for Ash; and Zoey and Kenny for Dawn. Nando is the only one absent.
