The official Japanese site of Pokemon has recently announced that the Pocket Monsters: The Origin anime TV special will be airing on TV Tokyo and its affiliated networks at 7:00 PM on October 2. Pocket Monsters: The Origin is based on the original Pocket Monsters: Red & Green games on the Nintendo Game Boy, and was produced by OLM, Production I.G., and XEBEC.
As expected of a TV special that was based on the original Gameboy games released in 1996, Pocket Monsters: Red & Green will not feature Ash Ketchum. Instead, the protagonist will be the original character from the game, the boy Red. You can check out the promo video below:
