Collects All-New X-Men #31-36. Dimension-hopping is something of an X-Men rite of passage, and it's about time the All-New X-Men took the plunge! You don't always have to travel Miles away to visit a new place…but will the Web in which these time-displaced young X-Men find themselves tangled Ultimately bring about their end? Okay, enough subtlety: The All-New X-Men meet Miles Morales, the Ultimate Spider-Man — and this is a showdown you won't want to miss! Will either universe ever be the same again? Guest-starring scores of Ultimate characters! Plus: It's Iceman unleashed as young Bobby Drake takes the offensive! And for someone who's said she doesn't find him particularly pleasant to be around, X-23 seems to have taken an odd interest in the highflying Angel. Tune in as yesterday's X-Men continue to explore the fear-fraught future of the present day!
