Devil Dinosaur by Jack Kirby Omnibus #[nn]

In "Devil Dinosaur and Moon-Boy," the red Tyrannosaurus Rex known as Devil Dinosaur defends his Valley of Flame from the monstrous Thunder-Horn, a Triceratops whose rampage ends with a dramatic fall from a cliff. As the dust settles, Moon Boy reflects on their bond—how he first found the wounded baby Devil, whose family was slaughtered by the Killer Folk, and how the volcanic fires that scarred Devil’s hide forged a brotherhood that endures. Now, with the Killer Folk united under a new leader, their peace is threatened once more.

In "Devil's War!", Devil Dinosaur fights to survive when the Killer-Folk unleash a brutal trap, setting the jungle ablaze and burying him under boulders. With Moon Boy captured and sacrificed to the monstrous Long-Legs, Devil Dinosaur breaks free and turns the flames against the Killer-Folk, unleashing chaos in the heart of their lair.

In "Giant," young Ruka, a member of the Big Ones—giant, fur-covered cavemen—has taken Moon Boy captive in the Valley, unaware his father, a towering warrior clad in a Triceratops skull helmet, is hunting him through the land, leveling everything in his path. When Devil Dinosaur confronts the giant, he tricks him into a bog, but as the father begins to drown, Moon Boy pleads for his life, prompting Devil to pull him to safety with a tree. With Ruka rescued, the giant departs the Valley, leaving behind a moment of unexpected connection in the chaos.

In "Object from the Sky," a massive alien spaceship crashes into the Valley of Flame, unleashing gold and blue humanoid robots with flamethrower arms that terrorize the land. When Devil Dinosaur battles one of the invaders, Stone-Hand and White-Hair—a pair of gray-furred Hill-Folk—step in to help, forging an uneasy alliance as they confront the invaders’ growing threat. Together, the trio devises a plan to stop the alien rampage before it consumes everything in the Valley.

In "Journey to the Center of the Ants!", Devil Dinosaur and his allies flee through a treacherous landscape, pursued by the Sky Demons and their monstrous Land Crusher. Trapped in the towering, pulsing hive of the Swarmers—gigantic ants that rule the Tower of Death—they must survive the alien threat and the colony’s deadly secrets before the sky above turns against them.

In "Eev!", Devil and his companions stumble upon Eev, a green-furred member of the Forest-Folk, as she’s attacked by two giant ants. With Stone Hand overwhelmed, Devil intervenes, dispatching the creatures before the rest of the enraged ant colony swarms the alien ship, tearing into its systems until it erupts in a massive explosion. Amid the chaos, Moon Boy and the captured cavemen flee, only to find a mysterious "Demon Tree" standing where the ship once burned.

In "Demon-Tree!", a mysterious sentient tree on a forgotten world lures Stone-Hand, White-Hair, and Eev with promises of safety and sustenance, trapping them in a glowing garden of illusion. As tensions rise and the cost of survival becomes clear, Stone-Hand must choose between surrender and defiance—while Devil Dinosaur and Moon-Boy close in, their arrival shattering the tree’s hold with a single, forceful charge.

In "Dino-Riders," Moon Boy struggles to reconnect with the Small-Folk when the fierce Dino Riders—cavemen clad in reptile skins and riding dinosaurs—launch a brutal assault on Devil Dinosaur, seeking to break and enslave him. Led by the ruthless Gray-Tooth, the raiders push Devil to his limits until Moon Boy rallies the Small-Folk, using cunning traps to turn the tide. With the Dino Riders defeated, Devil Dinosaur turns his fury toward Gray-Tooth, determined to end the threat once and for all.

In "The Witch and the Warp," Devil Dinosaur and Moon Boy stumble upon the enigmatic Hag, a withered guardian of the Pits—mysterious chasms pulsing with strange, glowing energy. When Devil accidentally falls in, he’s hurled into Zuma City, a modern desert town where he’s mistaken for a monster and chased by the military. Meanwhile, Moon Boy pleads with the Hag and her son to help him bring Devil back, as they send boulders into the Pits to trigger a surge of light. The story unfolds with a mix of wonder and urgency, as the two friends navigate a world far beyond their jungle home.
