This is Jean Grey, but teenage time-displaced Jean Grey who was brought forward in time. She's figuring shit out and trying to avoid becoming the Jean Grey Tragedy that everyone's familiar with, starting with the damn fiery orange space bird. She is cautiously hopeful that being stuck here means she's outside of time and space and maybe, finally safe from the Phoenix. She's a telepath who constantly hears people's surface thoughts (going any deeper than that is a conscious choice), but oocly that is totally opt-in. They might have trauma-related common ground that could be interesting to explore?
Bobby Drake cooljokes from Marvel 616. He's a charming dipshit. HIS teenage time displaced self (see above) outed him as gay and he's been dealing with that significant amount of lifelong repression. He specializes in bad jokes and trying to cheer people up. Also ice everything. He is staunchly in the "wants to go home" camp.
Stephen Strange supremed from Marvel 616. Just stopped fascist scientists from eliminating all magic in that dimension and is coincidentally here while it regrows. Which is okay with him, because he was in desperate need of a sabbatical because of what he had to do to stop them. But he's without his support mechanisms here (namely, prescription drugs) which is proving challenging. He's trying to help map this place out and find a way for people to leave if they want.
