Reception
The show received mixed-to-negative reviews, mostly due to the incredibly juvenile writing and personalities of the characters (Misty and May in the first season, and later Mash, being some of the worst offenders), as well as due to it barely focusing on any Pokémon, along with the many blatant references and severe padding. Some even went as far as to call it "the Teen Titans GO! of the Pokémon franchise".

Trivia

 * This is Satsuki Film Company's first television series, and their first collaboration with 1happycats Productions, who would end up purchasing the former in 2018.
 * It was rumored that the show was rejected by most of the companies affiliated with the official Pokémon anime, and Satsuki Film Company only accepted in hopes of attempting to get into the TV show industry.
