I have wonder what became of Gary Oak's Cheerleaders because they have been travelling with Gary all over the Kanto Region back in the original Pokemon Series and then after he lost the first Pokémon League his Cheerleaders disappeared when he travel the Johto Region by himself.

They did return in the Johto League Silver Conference were Ash and Gary battle each other for the very first time. After Gary was defeated his Cheerleaders were never seen or heard from again. It would be very interesting if Gary Oak have his spin off series because I'm always curious on Gary and his Cheerleaders adventure travelling in the Kanto Region just to compare to Ash and his friends.
