Synopsis: Continued from HULK #109) Zabu defends his master, leaping on the Hulk's back, but Hulk fights the tiger back! Ka-Zar tries to tell the Hulk that they need Banner to defuse the bomb. As the jungle lord and his cat fight the Hulk, the Swamp Men watch as a giant stone statue comes to life. The object of their worship is named Ombu, and was placed on the Earth many years before by an alien race that set him up to be the protector of the machine that is threatened to be destroyed by Ka-Zar and Hulk.

Ka-Zar cannot overcome the bestial fury of the Hulk and he is thrown across the valley, crashing unconscious near the Swamp Men, who decide to use him as a human sacrifice to Umbu on the Altar of Death. Umbu's progress to the machine brings him in line of the Hulk, and the two giants clash until finally Hulk is gassed and turns into Bruce Banner.

As Umbu lumbers toward the machine, Ka-Zar is strapped over a sacrificial pyre to be burned alive. His incredible physical strength allows him to slip out of his bonds and he frees Zabu, and together they fight back against the Swamp Men. Meanwhile, Bruce Banner has slipped into the cave and deciphered the alien circuitry of the machine, but Umbu has arrived and seeks to topple the mountain that stands over the cave. In a race against time, Bruce strips the master control unit from the machine, which not only negates its effect over the planet's axis, but brings Umbu crashing down to the Earth, now an inert, depowered giant.

After Ka-Zar and Zabu make mincemeat of the Swamp Men, they race back to the cave where they find Bruce Banner apparently dead from exposure to the machine's radioactivity.
