Crime Syndicate
The Crime Syndicate is a group of supervillains who are the evil counterparts of the Justice League in one of DC Comics' alternate universes. The initial group was known as the Crime Syndicate of America (CSA). In August 1964, Justice League of America, issue 29 introduced the first superpowered Crime Syndicate team. The Crime Syndicate of Amerika (with the variant spelling of America) was originally seen in the 2000 JLA: Earth 2 graphic novel.
A related successive group on Earth-3 is known as the Crime Society of America and first appeared in 52 issues 52, and was later featured in Countdown to Final Crisis. A "Golden Age" supervillain group, the Crime Society was to Earth-2 what the Anti-Matter Crime Syndicate of Amerika was to Earth-0 until it was removed from continuity following DC's 2011 Flashpoint storyline and The New 52 company-wide reboot. Following this, a singular Crime Syndicate is the Earth-3 counterpart of the Earth-0 Justice League, first appearing in Justice League issue 23 (October 2013), and the main focus of the company-wide crossover storyline Forever Evil. The events of that storyline have far-reaching consequences for the DC Universe and for the Crime Syndicate characters who survived and that remained on Earth-0 in one form or another after its events.
