Another of the many kaiju being controlled by the Xilien, Hedorah was actually not deployed by his alien masters during the other kaiju's worldwide assault, nor did he join the Xilien's ships in their combined attacks on Earth. The creature was dispatched, however, when Godzilla was finally reawakened. After losing many of their other monsters, the Xilien's teamed up Hedorah and Ebirah and sent them both against Godzilla in an attempt to finally defeat the nuclear leviathan. The three monsters raged underwater, but the Xilien's effort was for naught. Godzilla quickly tossed the Smog Monster out of the water, sending him colliding into a nearby building. Shortly after, Godzilla flung Ebirah out of the water as well, as the Sea Monster's giant claws pierced right through Hedorah's eyes as Ebirah went crashing into the pollution spawned demon. Godzilla wasted no time, though, and quickly fired his atomic ray at the two downed combatants, killing them both.
