X-Men: Road to Onslaught Omnibus #2

Plot

One of the X-Men's — and the entire Marvel Universe's - greatest threats begins to emerge and rear its head, in this prelude to the monumental and iconic Onslaught Saga!

Onslaught is coming! But first the X-Men must survive his herald: the punishing and powerful Post! Archangel and Wolverine join Doctor Strange on a quest for a mystical cure to Psylocke’s grievous, Sabretooth-inflicted injuries — but Warren too has wounds, both physical and psychological. Meanwhile, the Brood return, the Age of Apocalypse’s Dark Beast targets his Marvel Universe doppelganger, Wolverine succumbs to his animal side — literally — and the X-Men race to save a train full of commuters from Mister Sinister’s explosive experiments! Plus: Stories set in the past reveal the origins of Sinister and Apocalypse! The X-Men have reached the end of the road to Onslaught, but have all their trials been enough to prepare them for the mysterious villain’s imminent assault?
