An intelligent, noncorporeal life form consisting of coherent magnetic fields, sometimes manifesting itself visually as a luminous green cloud. A malevolent magnetic organism inhabited the dead alien pod ship discovered by the crew of the U.S.S. Enterprise on stardate 5221.3 (2269), and briefly took over the Enterprise's computers before being frightened into leaving voluntarily by Captain James Kirk. Without a ship to take over, the entity wailed to the cosmos about its loneliness and isolation.
