Strangers In A Savage Land!
Having recovered from his battle against Sauron, Angel learns from Havok and Lorna that the X-Men went after Karl Lykos at the Anderssen residence. There, Warren finds Mr. Anderssen and learns that the X-Men subsequently went to Tierra Del Fuego, going after Anderssen's daughter Tanya who had foolishly gone after Lykos who went there to die. Finding Tanya, she explains that Lykos died and tells him that his fellow X-Men had gone down below the icy cavern to find the body. Warren flies down and finds that the cavern leads to the Savage Land, where he is attacked by Pterodactyls. Struck by one of the dinosaurs, Warren plummets to the prehistoric jungle below. The fall is near fatal, and the dying Warren is found by a frog-like humanoid named Amphibious and his master, a silver haired man called the Creator. The Creator pronounces that Angel is dead and believes that even death is not reversible by his own science.
Elsewhere in the Savage Land, the X-Men have their own dinosaur troubles while searching for the body of Karl Lykos. They are attacked by a Tyrannosaurus Rex which they easily fend off. They are then visited by their old ally Ka-Zar, who demands that they be silent. When Iceman annoyingly encases Ka-Zar's pointed hand with ice, this causes the lord of the Savage Land to lash out. Ka-Zar briefly spars with Beast until the fight is broken off by the arrival of Ka-Zar's trusted sabertooth tiger, Zabu. Deciding that his fight is with others, Ka-Zar darts off into the jungle with Zabu, with the curious X-Men following after him. The X-Men witness as Ka-Zar attacks one of the Creator's Mutates (Equilibrius) leading the Swamp Men with a number of captured members of the Water People Tribe. When the X-Men see that the Mutates have super-powers, they jump into the battle, lending Ka-Zar a much needed hand.
While at the high tech base of the Creator, the Creator uses his cryogenic devices to attempt to revive Warren back to life while his other Mutates, Brainchild, Lupo, Gaza, Piper, Amphibius and Barbarus watch on. The experiment is a success and Warren is brought back from the brink of death. When Equilibrius returns to the base and informs the Creator that Ka-Zar had attacked him with the X-Men's aid, the Creator tells Warren that Ka-Zar has become a killer who impedes his work. Owing the Creator his life, Warren agrees to help him fight off Ka-Zar's attacking forces even if it means fighting his own comrades in the X-Men.
Back at the battle between Ka-Zar, the X-Men and the Swamp People, the heroes defeat the Swamp People and Ka-Zar allows them to flee. Leading the X-Men onward, he overhears the music played by the Mutate the Piper, whose music calls forth a sea beast to attack them. While the X-Men keep the creature busy, Ka-Zar and Zabu locate Piper and silence him, while the X-Men easily defeat the monster.
