X-Men Genesis: OOC

Alright, I'm making an application for Multiple Man and I'm having problems with choosing his affiliation. I know he shows up as a member of The Brotherhood in the movies but that is the only universe where he is part of The Brotherhood and I'd rather not put him under that. So I'm wondering if i should put him under either unaffiliated or college age (and under). 

If you have an opinion I would love to hear it so please leave a comment.
