Did you know that Nightshade, Peacemaker, Sergeant Steele, Blue Beetle, Judo Master, Captain Atom and The Question were all originally characters from another publishing company that no longer exists called Charlton Comics? Most of you probably did know that already but for the few who don't I thought you might have found that interesting. DC at some point bought the rights to the characters and integrated them into the DC Universe.
Nightshade pretty much became synonymous with both Captain Atom (the DC title of course) and The Suicide Squad. Peacemaker and Sergeant Steele made multiple appearances in both the Suicide Squad and Checkmate (both volumes). So I'm diggin Peacemaker re-design concept but I'm also looking to get some feed back on it from you good people. If you need a quick reference to his costume design as it was in the old DCU: http://suicidesquadtaskforcex.blogspot.com/2012/06/impel-trading-cards-series-task-force-x_21.html
