Rogue! outer_divide is probably slow for your tastes, but it's very interactive with a weird, wonderful sci-fi world and lots of mutants running around, though our Molly Hayes is the only 616 character. Kurt here would love to have his favorite pseudo-sister to annoy, even from another reality. We also have a OUaT cast with Belle, Rumple, and Mulan who I'm sure would like a Charming.
