In the original "Ghostbusters", Rick Morainis' Louis Tully becomes possessed by WHAT DEMI-GOD AND LOYAL MINION, who is also affectionately known as the "Keymaster of Gozer". You wouldn't be wrong to get the first name of the demigod from an African-Norwegian pop group. NAME THE DEMI-GOD/MINION (first and last name, naturally)
