Incredible Hulk, The (1968 series) #110

Zabu and his master Ka-Zar try stopping the Hulk, but he throws them far away into the jungle, knocking them unconscious.

Meanwhile, a four-arms stone monster called Umbu wakes up with a mission: to protect the menacing machine from being tampered.

The Swamp Men recall when advanced aliens they referred to as God Men brought that machine to Ka-Zar’s land, and left Umbu to protect it.

Umbu and the tribe walk towards the machine as they see how Ka-Zar and Zabu fall in the jungle. Umbu orders the Swamp Men to prepare Ka-Zar for a sacrifice, while he continues his journey towards the machine.

The gigantic monster finds the Hulk, who clashes with the stone titan. Umbu uses sleepy gas to defeat the Hulk. When he turns into Bruce Banner, Umbu simply ignores him.

Meanwhile, Ka-Zar escapes from his captors and defeats them.

And Bruce can decipher the alien circuits and remove the master control unit. Earth’s rotation returns to normal. Umbu stops functioning. But Banner’s long exposure to the machine’s radiation knocks him out!

Ka-Zar finds Banner dead on the floor!
