I'm an enormous fan of the Fantastic Four, if my name and title didn't give it away. I admit I haven't actually read their Ultimate universe comic yet, though I definitely plan to as I'm really interested in Ultimate Reed's character arc. For now, most of my knowledge comes from the 616-derived universes (and some weird AU miniseries that I found on Marvel Unlimited). I'd definitely be interested in possibly playing someone in this RP if you don't mind the caveat that I'm more used to the 616 version of the team.
