In reply to Watcher (msg # 2):
C or D listers make good candidates for this game. Off the top of my head, D-man or Texas Twister would be great fits.
I know someone is interested in Squirrel Girl. Between her own book and a major role in Marvel: Rising, she's probably more of a B-lister now. She's otherwise in the right mold though. Her buddy Kamala Khan is likewise closer to mainstream than I'd prefer, but could also fit.
Deadpool, Gwenpool, and anyone who breaks the fourth wall are a step too far.
