Checkmate (comics)
Checkmate is a fictional covert operations agency appearing in American comic books published by DC Comics. The antihero team first appeared in Action Comics #598 (March 1988) and proceeded to have its own ongoing title in Checkmate! (April 1988 to January 1991). In the wake of events depicted in the mini-series The OMAC Project and Infinite Crisis, Checkmate is re-chartered as a United Nations Security Council-affiliated agency and was again given its own series, Checkmate (vol. 2; June 2006 to December 2008).
