History
Uatu's history is presumably the same as his Earth-616 counterpart's up to the point when the Fantastic Four conducted their space flight that gave them their powers. On Earth-929, the Fantastic Four's ship crash, killing all those aboard. When Galactus approached Earth to feed upon it, Uatu tried in vain to hide Earth's presence from him. So, Uatu contacted the Avengers and alerted them to Galactus' arrival. As the Avengers fought to stop Galactus, Uatu directed Iron Man Worldship to retrieve the Ultimate Nullifier, but Iron Man was knocked out by the ship's defense mechanisms. When things looked hopeless, Uatu decided to break his oath of non-interference and opposed Galactus. Uatu was killed by Galactus, and the World Devourer fed on Uatu's life force. This satisfied Galactus' hunger, sparing Earth from destruction. Galactus then took Uatu's body to the Watchers' homeworld where it was burned on a funeral pyre.[1]
