Fantastic Four. Reckoning War Part I Vol 10.
(Book)

At last, the Reckoning War rocks the Marvel Universe! Eons ago, before the Kree, Skrull or Shi’ar Empires…before the emergence of Galactus…before the birth of Asgard…there was the First War. The greatest conflict to ever engulf the Multiverse. Today, it is reignited. This is the day of reckoning. And all that stands between the whole of reality and revenge from the dawn of time are the heroes of Earth…and the mind of Mister Fantastic! The most destructive force in the time-before-time is reawakening. And for the Multiverse to survive, all of the Watchers must break their most sacred oath! Dan Slott presents his cosmic saga fifteen years in the making — guest starring Thor, She-Hulk, the Silver Surfer, Jack of Hearts, Doctor Doom and more!
