T-Rex, or simply Rex, is the central antagonist in Alpha and Omega: Dino Digs. It is a ferocious Tyrannosaurus that was brought back to life, alongside Amy, at a magical burial ground thanks to the magic ray of light. After it was resurrected, it began to terrorize the forest. until Amy and her wolf friends managed to lead the Rex back to the burial ground.
The T-Rex is a huge light grey Tyrannosaurus with green pupils, sharp teeth, and short arms.
65 million years ago, a young female raptor named Amy was being chased by a T-Rex, as a meteor shower starts raining down, wiping out all the dinosaurs - including Amy and the T-Rex. In the present, the area where one of the meteors hit, is now turned into a sacred burial ground for humans to dig up ancient dinosaur bones. The leader of the human diggers Mac has built a golf course near the site, which upsets his brother Ian, who is an environmentalist. The humans have also built fake dens nearby for wolves. Both men arrive to the burial ground, as Mac explains that a museum will pay him millions of dollars for finding rare dinosaur bones. As the two trappers from the fifth film are digging, the sunlight causes Amy to magically be brought back to life.
The Tyrannosaurus did not show up again until the climax of the film. Mac sends more diggers to help Jethro and Griffin dig up the area, as Amy and the wolves come up with a plan to distract and lure them away. At first, they make it seem like the humans are surrounded by wolves on every angle by howling, which frightens some of the diggers and makes them retreat back into their trucks. This is followed by a stampede of caribou, driving the rest of the diggers away. Mac finally snaps and angrily starts digging for the bones, along with Jeffro and Griffin. However, the ground starts to shake, and the T-Rex comes back to life as the ray of light shines through the hole. The T-Rex then chases Jeffro and Griffin away, and then goes after Mac to throw him away from the burial ground. Kate, Humphrey, the pups and the others are trying to stop the dinosaur before the ray of light appears, as the T-Rex destroys their fake den (but the wolves aren't too bothered about it this time). Runt comes up with an idea to lure the T-Rex to the fountain lake, where the music can distract it from destroying everything. Amy lets the T-Rex chase her towards the fountain, where the music starts and distracts both dinosaurs, leading them into another dance sequence. Meanwhile, the ray of light finally appears on the burial ground, and they all head there while the T-Rex follows them. They reach the burial ground just in time, and after sharing their final goodbyes, Amy and the T-Rex magically return to their time.
- So far, it was not known why the burial ground was so magical and how it brought back the T-Rex and Amy.
- This T-Rex has the same roar as the Tyrannosaurus roar in the Jurassic Park franchise.
- The T-Rex is very similar to the Gray Sharptooth in The Land Before Time X: The Great Longneck Migration.
