Devil Dinosaur (character)

Devil Dinosaur is the titular character & tritagonist (along with Moon Boy) of the Disney animated film Devil Dinosaur.

Background
On the day the young Devil Dinosaur hatched, a tribe of Wild-Folk, hostile beings native to his planet, raided his mother's nest to steal her eggs for food. They were just in the process of stealing all but one egg when the mother Tyrannosaurus arrived & tried to fight them off. This fight was witnessed by Moon Boy, a young member of a rival tribe, the Small-Folk.

All of a sudden, a nearby volcano exploded, causing a rockslide to occur. Although some the Wild-Folk manage to escape, a few of them &, unfortunately, the mother Tyrannosaurus & her eggs were all crushed to death in a pile of falling rocks. Moon-Boy rushed to the last & only egg in the nest, as it was still intact & unharmed.

Exposure to the volcanic ash activated a mutation in the dinosaur so that when he hatched before Moon Boy's eyes, his skin had been turned to a flaming red, rather than olive green like his newly deceased mother. The moment the Tyrannosaurus hatchling laid eyes on Moon Boy, he assumed the Small-Folk to be his mother, & the two developed a powerful bond. As he grew quite rapidly, Devil Dinosaur became fiercely loyal to his constant companion Moon-Boy & seemed more intelligent than the average dinosaur.

Personality
For a dinosaur, Devil Dinosaur is highly intelligent & seems to understand most situations. He is fiercely loyal to those he connects with - & a big problem for those who oppose him. Because of his strong bond with Moon Boy, Devil Dinosaur tends to get jealous whenever Moon Boy is with others.

Physical appearance
A mutated Tyrannosaurus rex, Devil Dinosaur is twenty feet tall with amber eyes & flaming red skin. He also has crests on the top of his head that resemble devil horns, hence his name.

Powers & Abilities
He is a mutant dinosaur with human-level (or above) intelligence & superhuman strength. Also, his tough skin makes him almost invulnerable.

Devil Dinosaur
Devil Dinosaur & his partner Moon Boy first appeared when Linus Williams & Kyra Collins were abducted by the Wild-Folk. Just as Thorn-Teeth, chieftain of the Wild-Folk, was about to offer Kyra as a sacrifice, Devil Dinosaur came rampaging out of the nearby forest, roaring ferociously. He managed to fight off the Wild-Folk, forcing them to flee. Afterward, Devil Dinosaur took a close look at Linus & Kyra, both of whom were quite anxious at his appearance. However, Moon Boy, who's been on Devil Dinosaur's back the whole time, appears & assured the two that he was a friend.
