Tyrannosaur Rexo is a Tyrannosaurus Rex with a few robotic alterations that do not make him age. He lives in Toy Town, Bedroomia. He loves eating small things, such as Pokemon. Tyrannosaur wants dinosaurs to rule the Earth again, starting with Bedroomia. After he gets defeated by Doidle, he stays Toy Town... until Blazeter appears.
Tyrannosaur can eat anything even a millimeter smaller than him, but it takes around ten minutes to swallow it, if it's alive. He can digest anything but steel (his organs are the only parts of his body that haven't been altered). Tyrannosaur can also squash small things with his foot, and even throw things far away with his mouth. If on the floor, he uses his arms to get back up again, and his tail is detachable and works as a boomerang.
He believes that dinosaurs deserve to rule the Earth again. His desires block his mind and give him an angry nature. After he gets defeated by Doidle, his anger levels got low, and he was able to have other feelings. However, he does not consider Doidle a "Friend", because of not allowing him to make dinosaurs rule. He never had a chance to meet Tata...
Tyrannosaur Rexo is very tired of "Fictional Dinosaurs" and "Overgrown Animals", "Ruling" Bedroomia. So he has planned to awake the sleeping dinosaurs and destroy the Guardians of Bedroomia, then take on the town, then the United States, then South America and Canada, Europe and China, Islands of the Caribbean, and finally Africa and Oceania, as well as all the smaller islands and Antarctica. He says that in 2 weeks, the world will become rightfully theirs. However, his plans are thwarted by two dogs (or one dog and a TimeSplitter) named Doidle and TimeSplitter Dog. Tyrannosaur warns them to stay back or he will revive all dinosaurs, dinosaur toys and dinosaur plushies. TimeSplitter Dog tries to convince him that there are lots of things out there that can easily defeat toys. But Tyrannosaur reminds them that he also said DINOSAURS, as in, the prehistoric land reptiles. They seem forced to fight him. First thing TSD does is take away what will revive them. They fight for a long time, with lots of close calls. But in the end, the controller that would revive the dinosaurs was torn apart by Godzilla, making Tyrannosaur furious. But Godzilla fights him in a short fight, and eventually Godzilla is taken down. Doidle punches Tyrannosaur as hard as he can in the face, and Tyrannosaur is blown to Toy Town, and not seen again by the plushies until Blazeter arrives.
