Pokémon Black (not related to the new Pokémon Black/White) was an urban legend. Some say it is real. That it was a game created by Satan himself. Others say never believe anything you see on 4CHAN’s /b/. I think they are both correct.
Some disturbed individuals have decided they need to make the legend reality. Pokemon Ghost Black Retold is a visual novel based on the “Creepy Pokemon Hack” story.
The story as told by the Anon that first reported its existence.
