I remember when I had to constantly try to correct people that the main character in Pokemon Red and Blue wasn’t Ash, but actually ‘Red’. Some guys at the Pokemon Company probably had the same problem as well, so now there’s a new special on the way that’ll shut people up… AND NO, THAT ISN’T GARY OAK IN THAT TRAILER.

During the Pokémon Game Show, it was announced that a brand new anime special will run to coincide with Pokémon XY. This anime is called Pokémon: The Origin, features Red & Green, is based directly on the games, and is to air on October 2nd as a special broadcast. The show features Red as he starts his journey and battles his rival Green, and the Gym Leader Brock.
