At an Army base in the desert, Dr. Bruce Banner is readying the first test of his invention, the G-Bomb. Banner takes a last look at the bomb with binoculars. He notices a teenage boy in a car, who he gets to safety in a ditch, but before he can jump in himself, the G-Bomb explodes! Gamma rays saturate Banner's body. Hours later, Banner regains his senses. The boy, Rick Jones, who drove onto the base on a dare, brought him back to base. Banner waits for some kind of symptoms to appear. When night falls, Jones turns on a "radio," actually a Geiger counter. Its clicking increases, and Banner changes into a huge green figure. After the monster destroys a military base, General Ross demands that this monster, now dubbed “The Hulk” be brought in. While this happens, a doctor named Donald Blake finds a staff and becomes the Mighty Thor. Soon Thor sees the rampage and decides to intervene.
