Janus

"That's Janus, a Roman mystical God."

- Rupert Giles

Janus was a god worshipped in ancient Rome. A sculpture of the god's head, representing him with two faces - one male and one female - facing in opposite was used by Ethan Rayne on Halloween 1997 to transform the population of Sunnydale into the characters of the costumes they had bought at his costume shop.
