Anything can happen in WHAT IF? - and this is the Omnibus to prove it! Imaginative creators line up to explore alternate possibilities in unexpected ways, featuring amazing, incredible and uncanny variants of all your favourite heroes! Ask yourself the important questions: What if the alien costume possessed Spider-Man? What if the new X-Men died on their first mission? What if the Fantastic Four all had the same power?! Plus, Professor X becomes the Juggernaut, Wolverine is an Agent of S.H.I.E.L.D., Daredevil kills the Kingpin... and the Punisher's family survives! Captain America won't give up the shield, Iron Man loses the Armor Wars, and the Vision destroys the Avengers! But when the Timekeepers step in, can the multiverse survive a cosmic crossover between the many worlds the Watcher has witnessed? Collecting: What If? (1988) 1, What If?
