Nightmare (マジシャン, Majishan, Magician) is an enemy which appears in Suikoden.
Nightmares are skilled magic users, using a variety of elemental magic that can quickly catch a party off guard if unprepared. There is the possibility that they will heal your party, however. Nightmares are also the only source of the Opal, necessary to recruit Esmeralda in Antei.
