What do you get when you mix five time-displaced teens, a time machine and one fractured timeline? You get Jean, Scott, Hank, Warren and Bobby - impromptu time cops! The original X-Men and their new allies must survive long enough to fix what went wrong with the timestream - which isn't easy when they're stranded in the not-too-far future. If only there were a similar group of mutant heroes that could help them out - like the X-Men 2099! The adventure through the eras continues as the Blue crew meet the original Generation X! And back in the past, they're reunited at last with Professor X - and the villainous Magneto! But with the timestream in ruins - all the fault of the X-Men - can they fix everything that has gone wrong...even if it means battling themselves? Collecting X-MEN BLUE #16-20.
