CROSS-TIME CAPERS Part 2
Lost in time, JEAN GREY and her team of X-MEN must survive long enough to fix what is wrong with the timestream... which isn't easy with the teens stranded in the not-too-far future. If only there were a similar group of mutant heroes to help them out.
Oh, wait! There totally is! GUEST-STARRING X-MEN 2099!
