History: (Fury of Firestorm #38, 39)-John Monroe was a student at Stanford University, where he was known as an unlikeable loner. The few people that gave him any notice called him the Weasel. John was embittered by this, but pent up his rage. Twenty years later he was working as a teacher at Vandemeer University, where several of his fellow Stanford alumni also held positions. John convinced himself that his old acquaintances would talk badly of him and cost him tenure. He devised the costumed identity of the Weasel and brutally murdered them, in addition to a night watchman who got in his way. Soon afterwards, Dr. Martin Stein, the physicist who was part of the composite being Firestorm, arrived to fill a position at Vandemeer. The Weasel twice tried to kill Stein, until Firestorm defeated and unmasked him. Weasel was sent to prison for a long stretch.
