was briefed on the Chitauri and sent to investigate a suspected Chitauri base in Micronesia. They were saved by Iron Man's force field after they discovered the base abandoned and ready to explode. Once a Chitauri fleet appeared in Arizona, Thor brought the survivors there. He and Iron Man then provided air support against the Chitauri spacecraft until the Air Force arrived. After Iron Man asked Thor to help him dispose of the Chitauri bomb that would obliterate the entire solar system, Thor teleported it to the wastes of Náströnd, a deserted world in the Asgardian cosmos where its detonation caused only a small ripple in our space-time. In Ultimate War, Thor appears as a member of the Ultimates, retrieving the dead with Iron Man after the attack in issue one.
