In an alternate universe where Thanos has won, the world lies in ruins after the fall of Earth and its heroes. Refusing to accept extinction, Lucifer Beauregard / Red Hour and the remaining survivors escape beyond reality itself, entering the Nexoverse—a new universe untouched by the Mad Titan’s conquest.
From their sanctuary on Northstar Island in the Terranova Realm, the survivors regroup, rebuild, and form the X-Avengers. As Thanos tightens his grip on existence, Lucifer’s Omega-level chaos and cosmic magic may be the key to striking back, reclaiming their lost home, and ending the Titan’s reign once and for all.
