An Aspect of the Midgard Serpent Jörmungandr. Vigil, Ultimate, Mike, Caledon Chanter, Khana and Bana answered the call.
During the battle War was swallowed by the serpent when protecting Caledon. The Serpent got off two blasts. One vaporized the tops of several buildings while the other created a tunnel that went under the city.
When defeated, War seemed to vanish with the Serpent.
