Early Life

Devil Dinosaur & Moon Boy (Earth-78411)

Moon Boy & Devil Dinosaur

Moon-Boy was born into a tribe of ape-like beings known as the "Small-Folk" who made their home in the "Valley of the Flame", a region of numerous active volcanoes in a parallel version of Earth-78411 known as Dinosaur World.[5]

Devil Dinosaur

Moon-Boy’s connection with Devil Dinosaur began on the day he came across a female dinosaur being attacked by a rival tribe known as the “Killer-Folk”. The female was killed, as well as two of her three young. The third did not die however, but was transformed when the Killer-Folk attempted to burn him to death with their torches. The fire permanently scorched the young dinosaur's skin bright red. Moon-Boy cared for the orphaned creature after its ordeal and named him "Devil". Ostracized from his tribe because of his association with Devil, Moon-Boy and his red companion became wanderers.[5] After nearly falling for the trap set by the Killer-Folk, Devil Dinosaur, crashes into the spikes, using his momentum and immense weight to break them without damaging himself. As Seven-Scars' plan failed he resorts to his backup and buries Devil Dinosaur in a mountain of rubble he gets the Killer-Folk to drop on him. Presuming Devil dead, Seven-Scars takes Moon Boy captive and takes him to the cave of Long-Legs as a sacrifice. When they leave, Devil manages to free himself from the rubble, exhausted but alive, but before he gets time to recover he is attacked by an Iguanodon. A short battle ensued which Devil eventually won, and began tracking down Moon Boy to Long-Legs cave. Back at Long-Legs cave, Moon boy has been tied up and is about to be attacked by the aforementioned Long-Legs but is rescued by Devil wielding a flaming branch from the Burned Valley. He sets fire to some grass trapping the Killer-Folk in a circle of fire and rescues Moon Boy and steps on Seven-Scars, who tries to stop their escape killing him. The rest of the killer folk are pushed back into the cave and are all attacked and presumably killed by Long-Legs, Devil and Moon Boy leave while a Mysterious figure watches them. [6]

Fight With Thunder-Horn

After being woken up in the middle of night by a loud strange sound, Devil Dinosaur and Moon Boy go to investigate a strange figure whose encouraged on them sleeping. After giving chase, a giant rock is hurled at Devil throwing him off balance, a feat which no living creature should be able to do. Continuing the search Moon-Boy sees a figure that is bipedal with a Thunder-Horn Head. The next morning Moon-Boy leaves alone and finds the figure, turning out to be a Giant humanoid wearing a mask, fighting Bone-Back. After defeating Bone-Back, the Giant calls out Ruka and Moon-Boy attempts to leave but is captured by another figure. Meanwhile, Devil Dinosaur has discovered Moon Boys disappearance and follows a trail of dinosaur body's to the Giant. When he meets up with The Giant, a battle ensues but both seem equally matched so Devil attempts to lure The Giant to a bog. The Figure who captured Moon Boy is revealed to be a much smaller Giant figure, escaping his captive Moon Boy leads the younger Giant to the same bog that Devil is at, just as the Giant is tricked into falling in. Moon Boy then reveals that Th younger giant is the other ones cub and they proceed to rescue the giant from the bog and he leaves with his son in arms, with a truce between the Big Ones and Devil Dinosaur been formed. [7]

Sky Demons

In the midsts of having Nightmares about creatures from the sky coming to destroy the entire valley, Moon-Boy falls out of his tree and witnesses something crashing to earth. It crashes with such an impact it begins tearing the land apart so Devil Dinosaur and Moon-Boy leave to investigate the source. They arrive at the crash sight and unbeknownst to them it is a space-craft, out from which come humanoid alien/robot creatures that Moon-Boy dubs sky demons. Who begin to lay waste to all life-forms, knocking out Devil and capturing Moon-Boy and taking him aboard there craft. While the robots begin destroying the valley, two of the Hill Folk tribe, White-Hair and Stone-Hand seek out Devil in hope of him aiding them.Finding him after just recovering from his unconsciousness, the pair witness him taking out one of the "Sky Demons". But as Devil turns his back the sky demon is not fully dead and Stone-Hand saves his life from the aliens attack. The three then strike up a partnership, with the hill folk following Devil as there new leader. Returning to the craft, the trio witness the aliens taking both Dinosaurs and the Hill-Folk being taken aboard for study. When one tries to escape, he is instantly vaporized. Fearing for there lives Stone-Hand tries to leave but White-Hair insist they stay with Devil, who turns away from the craft and starts towards The Tower of Death, in a plan to overwhelm the invaders with what lies within. [8]

Battling the Swarmers

Moon-Boy finds himself locked in a glass case, and the aliens knock him unconscious in order to further investigate his intelligence and its future potential. Meanwhile, Devil Dinosaur, White-Hair and Stone-Hands are on there way to the Tower of Death when they are attacked by two of the aliens. Using a geyser, Devil seemingly kills them and they carry on there journey, he in fact has only destroyed one of them and as they arrive at the tower the second one catches up and attempts to kill the trio again. Just as the alien begins to charge up he is destroy by Swarmers, which are giant ants that have the tower as there home. Returning to the ship, Moon-Boy is still being experimented on and the aliens find that he has the greatest intelligence potential of all the races they have analysed. Worrying about the same potential for intelligence possible in Devil, they send out a land crusher to destroy him. Back with Devil and the others, the swarmers have begun there attack on the trio for trespassing, and climbing onto the back of the Devil. They all head inside the tower with White-Hair speculating that Devil had done this before as he is largely able to avoid the bulk of swarmers. Just as they are discovered by the Swarmers, the land crusher destroys the tower, which sends the Swarmers into a frenzy and they attack the crusher destroying it, with the swarmers then carrying onto the spacecraft. Leaving the trio alone, tired and weary from there ordeal. [9] Leaving Devil Dinosaur to recover, Stone-Hand hears a female cry out and finds the Forest-Folk, Eev being attacked by a couple of swarmers. After failing to rescue her, the pair are saved by Devil who doesn't kill the swarmers much to the annoyance of Eev. Eev had gone to the tower of death for the swarmers food, while they eat they observe the swarmers heading towards the spacecraft of the Sky Demons. Inside the craft, the aliens have concluded that Moon Boy and his race are too risky to let them evolve into there full potential so take him away to killed and one of the aliens orders the extinction of all Hominids. Before anything can be done however, the swarmers begin to destroy the spacecraft allowing Moon Boy to escape. Devil and the trio of Homonids observe the ships destruction and Devil, assuming Moon Boy has perished, leave the three in sadness. Stone-Hand then proclaims Eev is his wife but she flat out refuses but stone-hands will not listen, ignoring the pleas of White-Hair and Eev.Moon Boy, tries to flee the ship but is nearly crushed by all the escaping dinosaurs so is one of the only creatures left when the ship explodes like a nuclear bomb. Leaving behind a device that calls itself the prime computer. Fearing for his life Moon Boy flees looking for Devil being nearly eaten by several dinosaurs. Hiding in a cave Moon Boy has flashbacks of him and Devil. It begins to rain just as Stone-Hand, Eev and White-Hair stumble across the Prime Computer, who calls them closer proclaiming he will not harm them.[10]

Prime Computer

Finding Prime Computer and the three New Folk, Devil Dinosaur is thrown away by Prime Computer at the praise of Stone-Hand and Eev and eventually is forced to flee due to the computers power. The computer them imprisons the three in a glass dome in order to prevent harm to come to them, Stone-Hand and White-Hair are unhappy about this but Eev is more accepting. Back with Moon Boy he leaves the cave he was hiding in only to be attacked by a hungry Hopper. Fleeing through the swamps he is nearly crushed by a giant Plant-Eater, but is still unable to escape the Hopper. Just as he is about to be caught he is rescued by Devil and the pair are reunited. Prime computer has turned the dome prison into a mini paradise, which both Eev and White Hair have come to accept and enjoy. Stone-Hands however, wishes to be free but his attempts to destroy Prime Computer are thwarted. Devil and Moon-Boy eventually return to the computer, finding that White-Hair has died from what later turns out to be radiation poisoning. Feeling the computer lied about there guaranteed safety Stone-Hand, renews his attacks on it. Damaging it, Devil then charges the weakened barrier breaking it, which causes a feedback to the computer and destroys it making the garden disappear and freeing Eev and Stone-Hands. The pair leave proclaim they will never forget what happened and will tell the story to everyone. [11]

Battling the Riders

While searching for the Small-Folk, Devil Dinosaur and Moon-Boy are observed riding together by a pair of Riders, pre-humans who ride dinosaurs. They rush back to there tribe with the intention of returning and capturing Devil and using him as there leaders new mount. Moon-Boy meanwhile, finds the Small-Folk hiding in a cave, still fearful of Devil and the new tribe of riders. Moon-Boy proclaims Devil while protect them, just as a roar from Devil shakes the cave. Rushing outside Moon-Boy finds the riders attempting to catch Devil with vines, before too long, Moon-Boy helps free him and they begin a counter-attack on the riders. When there leader, Gray-Tooth appears riding a Thunder-Horn, he charges the pair, which is enough of a distraction for Devil to be pulled to ground and quickly blinded with mud. Moon-Boy escapes before he can be captured and returns to the Small-Folk to enlist there aid in freeing both Devil and the Valley from the riders. After some consideration the Small-Folk agree and a plan is set-up. Back with Devil, the riders attempt to break his spirit with a mix of an odor-bag placed over his head and a ritual by The Spirit Killer. Before it is finished however, the small-folk begin there attack, tricking many of there riders to fall to there deaths and into the swamps. Moon-Boy goes to free devil but is stopped by Gray-Tooth, who begins to charge down him on the Thunder-Horn. The sight of which breaks Devil from his stupor and rescues him before chasing down and presumably killing Gray Tooth. The pair leave, tired but together again. [12]

Moon-Boy is rescued from the edge of the pit, by the Hag and her son, who eventually yield to Moon-Boy pleas to rescue Devil. The trio proceed to a different pit where the hag and her son drop massive rocks into the pit which explode, opening another inter-dimensional portal between there world and earth-616. Seeing the portal Devil, rushes back through the portal and is reunited with Moon-Boy and the two flee the pits, vowing to never return.[13]

At that time Godzilla suddenly resumes his original size. While on present-day Earth, Reed has the time machine taken to a safe place, but instead of exploding, it transports the full-sized Godzilla back to the present at full size, smack in the middle of New York City.[15]
