The California Air Force Base discovers a huge comet heading towards the Earth and fears for the worst. Glenn Talbot is serving on that base, temporarily. Bruce Banner hears about the comet on the radio and shows up on the base with an idea of piloting a rocket that would carry an atomic nuclear warhead which blasted on the tail of the comet would destroy it. His heroic idea gets approved.
Partially sedated to prevent his transformation, Banner pilots the rocket and accomplishes the mission!
As he flies back, Banner sees the Absorbing Man attached to the rocket! The villain had merged with the comet somewhere in space and tailored it to our planet.
Tension turns Banner into the Hulk, who meets his opponent outside the rocket. The ship crashes on the ground, but both survive.
Jade Jaws seems to take the upper hand. But Crusher Creel siphons the Hulk’s power, weakening the green giant. The villain lifts a hillside to smash his opponent as Ol’Greenskin turns into Banner! With his power source gone, the Absorbing Man weakens and gets crushed by the mountain!
As Banner moves away, unharmed, we discover a group of strangers witnessing the incident from a distance...
