Weasel is the name for four villains the DC Universe, the first of which being part of the Rouges Gallery of Firestorm, The Nuclear Man. Two other individuals bearing the name are from the future, while the fourth is part of an evil circus called the Circus of Strange.
John "Jack" Monroe was a student at Stanford University in the 1960's. He was brilliant but a social outcast owing to his thin frame and narrow features, which earned him the nickname "weasel" by his peers and made him the target of constant bullying. The constant torment drove Monroe to become a sociopath and, decades later, a serial killer.
As an adult, Monroe became a teacher at Vandemeer University in Pittsburgh, Pennsylvania where a number of his fellow childhood students now held prominent positions. Monroe was rarely noticed by his contemporaries, but convinced himself that they were constantly plotting behind his back to prevent his acquisition of tenure. He developed a light but flexible and rugged fur costume suit, equipped with claws on four fingers of each hand and began stalking his peers using the identity of Weasel. He murdered three of his associates before turning his sights on his newest supposed rival, Martin Stein.
Stein was also a contemporary of Monroe, having attended Standford University with him but at first having no recollection of Monroe whatsoever. Believing that Stein was also one of his tormentors, Weasel made two attempts on Stein's life. After the first attempt, Stein was able to piece together his attacker's true identity, which lead to Weasel making a second attempt. In the second attempt, he would have succeeded in murdering Stein had not Stein triggered the transformation into Firestorm. Firestorm defeated Weasel and unmasked him. Weasel revealed his motivations to the hero, causing Stein to take pity on him before handing him over to the authorities for incarceration.
Weasel was one of a number of villains recruited into the Suicide Squad for their ill-fated mission to rescue Hank Hall, the Hawk. During the mission, Weasel managed to cause the apparent death of Thinker. Rick Flag, Jr. was then told by the Thinker helmet to murder Weasel, which he did.
During the Blackest Night, Weasel's body was among those entombed in the Hall of Justice. When the Black Power Rings flew in, Weasel was reanimated by the Black Power Rings and inducted into the Black Lantern Corps.

Solomon Grundy used this little slime to do the talking for him. As Grundy could only grunt. Possibly the real power within Grundy's gang of crocks. He was arrested by Batman and Black Canary when the gang tried to steal the brain of a Nobel Prize winner.
