So the protagonists of the 52 story were an alternative earth where Diana Troy, Dick Grayson and Kyle Rayner all replace their mentors?
The current Challengers of the Unknown are Donna, Kyle, Jason (Todd), and the Atom (not Ray Palmer) of New Earth. Oh, they have a monitor with them...his name is Bob. They traveled to Earth-15 looking for New Earth's Palmer. While there, they ran into their counterparts who took over for Bruce, Hal, and Diana. Check out the first post in this thread for the other info. I made it simple cause thats how I like my men!!
