The Avengers and the X-Men join forces to create a brand new team of heroes! The FALL OF X calls for the return of the Avengers' Unity Squad! Innocent people and world leaders are dead after simultaneous attacks on the U.S. and Krakoan governments, and that means one thing: It's time for a new squad of Avengers! False-flag attacks meant to whip up anti-mutant hysteria are unfolding and hey, some of Steve Rogers' best friends are mutants. So Captain America enlists Rogue, Deadpool, Quicksilver, Psylocke and Monet to solve the mystery of who the new, murderous Captain Krakoa is - and stop his team of killers from igniting the fires of a new world war!
