Hello! I'm Churby and I play this local mutant genius. He's already been asked by Jean Grey (I suppose in the past because Tony's here now, damn that weird temporal rift throwing Tony into the future), to talk to Tony about his other world experiences, sorta compare notes.

I also bring with me some interesting awkward CR potential. David's from after a point in comics (though it was in an Ant Man comic) where he tried to get a job as head of security for Stark Industries and lost out to Scott Lang. He doesn't have any hard feeligns about that,but from his point in time he would have met Tony beyond the general influence Avengers always seem to have in the lives of Mutants.

Other than that, come hang out with a currently-a-technopath?
