Dark Pokemon, which should not be confused with Dark-type Pokemon, are pocket monsters who have turned to the shadier side of things, almost always due to their trainer being such a character themselves

This card was released in 1997 as part of a promotional Topsun set inserted in chewing gum packages in Japan
