A new Character Donation; because YOU (or, at least, one of you), demanded it!
Face it; shadowy extragovernmental agencies with cute names are very Marvel. SHIELD! AIM! I assume it's because Marvel's heyday commenced in the anticommunist spy-crazy days of the 1950s and 1960s.
DC is more about apparently boring but dangerously intrusive government bureaucracies like the Bureau of Metahuman Affairs and the Department of Extranormal Operations. Plastic Man was an FBI agent, for pity's sake. Perhaps because DC's roots are in the agency-crazy New Deal era?
Checkmate. The snazzy shiny high-tech costumes. The crushingly heavily handed overuse of extended chess metaphor (Hellfire Club, anyone?). The lack of apparent sources of funding. The lack of apparent purpose (until Max Lord came up with one!). Marvel, Marvel, Marvel.
After its aborted series (which not even the starpower of Harvey Bullock could save), Checkmate languished without portfolio until becoming, through an editorial fiat of convenience, Max Lord's Evil Inc. That its featureless and unknown cast could so easily be recast as the Grand Order of Occidental Nighthawks shows how redundant and out of place it is in the DCU.
Marvel, however, would have a ball with Checkmate, and there's always another side to be taken in the Us Versus Them Versus Them Versus The Other Guys Marvelverse.
DC, don't try to reanimate the corpse of uninteresting Checkmate; send it Marvel, where it might make a rather interesting zombie.
