I have always like the idea of the government run task forces (Shield, Checkmate, ect.) and have always wanted to include a representative of CHESS in my games. I can not actually find any published character sheets or even pictures of what the power armor looks like. Any help or suggestions?

Yeah, there's a ton of markers for Knights and Valkyries in numerous adventure supplements. They look the same; the Knights wear light blue and the Valkyries pink (or dark pink, depending on which module).  Rooks (and Doves, their counterparts) were just James Bond-type agents, and the only major characters they had were Homer Grimsby (the King) and Alexandria Huntington (the Queen); Dawn of the Devil had stuff on them (their offices and such), but I'm pretty sure they never statted them out.

I believe the ones that had them (I'm going from memory here) include Most Wanted Volume 1, The Secret in the Swamp, and Dawn of the Devil, plus probably a few more.

  Cool, thanks for the info, figures three of the four modules I don't own.

Thanks Majestic and dsumner.
  I found a counter for both Knights and Valkyries. It's only a head and shoulders pic, but assuming the rest of the armor follows suit, I'm going with something like this:

I saw the episode, is the comic DC or Marvel... I don't guess it really matters at this point, as has been said here, the chess theme has been used many times.

There have been two separate Checkmate comics. In the first run Checkmate was a US government organization, similar to the SHIELD. The second run had them operating under a UN mandate. I preferred the first run.

I just read this now and see where the whole CHECKMATE idea was already used. It was right in front of me the whole time. Lovely......
