Suicide Squad 2: 10 Comics James Gunn Should Adapt
9. Checkmate: The Game Of Kings
While Task Force X, the Suicide Squad's official name, was the secretive wetworks team, Checkmate was the United Nations sanctioned organization that was designed to bring down superheroes and supervillains that got out of line. It is the political counterpoint to the Suicide Squad and also has Amanda Waller serving as the group's handler.
A political thriller first and foremost, this particular arc from the comic saw Waller attempting to put out the flames after a ground force in China is discovered, and all hell breaks loose because of it.
The first film set up the idea that the government was willing to have a covert operations force to battle metahuman threats, and its ending showed that maybe it wasn't the brightest idea. Either way, a story that follows both the political aspects of the team of criminals doing the government's work paired with the presence of Checkmate would help revitalise the Squad, and go some way in convincing viewers to sign up for the sequel. (Whenever it releases.)
