Gengar is a ghost and posion type pokemon. The toasted mate gives a smokey ghost feel, while the assam melody gives a dark and heavy feel. The cool peppermint gives the feel of Gengar's special ability heat sink. The hibiscus accent gives that zing of a poison type.
I am in no way associated with pokemon. This is purely done to share the love of pokemon in a new way. I do not own the artwork. It is the official design of gengar by Ken Sugimori
