There isn't a formal wanted list in the mod journal, but I know the Supernatural folks would love Crowley, the Whovians are looking for River Song (we have the Tenth and Eleventh doctors!), the Trek-ers would possibly kill for Spock (seriously, how do we have his parents and not him?!), and I would personally die if there was anyone who played anyone in the Enderverse. Bonus points if it's Achilles, because the thought of Achilles and Petra marooned together in space makes my head spin in epic ways.
