Warguard
Former scientists and personnel aboard the Monitor-One space station, those who became the WarGuard were exposed to highly volatile radiation from a passing comet that damaged the station. They survived, were mutated and gained phenomenal powers, which drove them mad. It took StormWatch Prime and an army to put them into cryogenic suspension. The United Nations kept them frozen to use as a last strike option should the Earth be threatened by an overwhelming force.
Watchmen
Watchmen is a twelve-issue comic book limited series created by writer Alan Moore, artist Dave Gibbons, and colorist John Higgins. The grouping of heroes and villains contained in the work are not, in fact, named "The Watchmen", though they were at one point referred to as "Crimebusters". Rorschach, Nite Owl and Dr. Manhattan were the team's primary heroes.
