Collects Ultimatum: Spider-Man Requiem (2009) #1-2, Ultimatum: Fantastic Four Requiem and Ultimatum: X-Men Requiem (2009).
The Ultimatum Wave has come. What is left? A torn mask. The last vestige of Peter Parker. A fractured family. Ripped apart by the forces of nature. A team cast to the wind. Annihilated by Magneto's Ultimatum. For the heroes, it was a time of sacrifice. For the witnesses, it was a time for inspiration. For the survivors, it is a time for requiem. After which the Ultimate Universe of heroes will truly never be the same.
