I'm definitely interested in having your guy as a historian/secretary and maybe even potential advisory type role during their super secret meetings? I think my guy is going to be open to hearing input from all of the small inner circle regarding decisions and the like.
I'm thinking probably about 5-ish inner "ruling" circle type people and then all the recruits and so on and so forth down the line. If you come across anyone else or have any other interest that want in on brilliance I'll be happy to set up a custom for shenanigan/plot discussion. I know personally I want a Kitty Pryde or Blink-type Evo for his personal protege and maybe some wildcard normally "good" type powers that have been sucked into the dark side this go around.
I think outwardly he plays up more of the "justice for all" type in his day to day life to throw off suspicion. Gentle giant and all that.
