Height: 5.3m Length: 13.2m A Tyrannosaurus Rex known as the King of the Tyrant Lizards. She is the most powerful of her species, possessing a strong instinct to protect her kind and a high sensitivity to territory. While she normally would have fought any other dinosaur on sight, the appearance of Distortus Rex and her own survival instincts have led her to form an alliance with Giganotosaurus, Spinosaurus, and Indominus Rex.

Height: 5.5m Length: 14.5m Possesses immense pride and frequently challenges dinosaurs larger than itself. It attacks any dinosaur that encroaches on its territory and has an incredibly hard skull. Due to the emergence of Distortus Rex threatening its domain and survival, it has allied with Rexy, Spinosaurus, and Indominus Rex.

Height: 8.4m Length: 13.5m Also known as D-rex, this is a mutant hybrid dinosaur created by combining the DNA and genes of various carnivores and herbivores. Side effects during the splicing process resulted in extreme aggression and hypersensitivity toward territory and death. It attacks Rexy, Spinosaurus, Indominus Rex, and Giganotosaurus for invading its space. It possesses incredible battle intelligence, weight class, destructive power, and size. It has two pairs of forearms, two hind legs, a lump-like growth on its head, and is capable of throwing punches.

Height: 6.5m Length: 26m A marine reptile. While generally docile, it becomes extremely sensitive to the roars and territorial instincts of other terrestrial and aquatic dinosaurs. If there is a disturbance or loud noise near its territory, it will charge and attack with devastating force.

Height: 2.5m Length: 6m A hybrid dinosaur created by combining Raptor DNA with Pteranodon genes. They establish a hierarchy within their pack and cooperate to attack other dinosaurs. They are highly aggressive and sensitive about protecting their packmates and territory. They possess very high IQ and social skills. Equipped with wings, they are capable of flight and occasionally assist Distortus Rex.

Height: 4.9m Length: 12.3m A pack of four Spinosaurus, each with distinct stripe patterns on their sails. They maintain a strict hierarchy and are sensitive enough to attack any dinosaur that enters their territory immediately. Some members are aggressive while others are docile; if they encounter another Spinosaurus, they emit a vocalization inviting it to join the pack.

Height: 5.8m Length: 13.1m A Tyrannosaurus Rex like Rexy. He will fight any dinosaur regardless of whether they are his own kind. When Spinosaurus, Giganotosaurus, Indominus Rex, and Rexy caused a disturbance in his territory, he regarded them as enemies and attacked. He is intelligent with high battle IQ but realizes he is outmatched against Distortus Rex.

Height: 5.4m Length: 12.8m The most clever among the carnivorous dinosaurs, possessing high IQ, battle intelligence, and memory. When encountering other large dinosaurs, he remains wary rather than attacking first and is capable of manipulating others. Upon the appearance of Distortus Rex, he realized he could not win alone and allied with Rexy, Indominus Rex, and Giganotosaurus out of survival instinct.

Height: 20m Length: 37–40m An ultra-large sauropod herbivore that travels in herds. It has an extremely long neck and tail. It is very gentle, but if attacked, it swings its long tail like a whip. Though very slow, its sheer size gives it an aura so imposing that most dinosaurs (except Indominus Rex and Distortus Rex) dare not approach.

Height: 5.2m Length: 13.9m A hybrid dinosaur created from the DNA of Raptors, Tyrannosaurus Rex, Tree Frogs, and Cuttlefish. Second only to Spinosaurus in cleverness, it has very high battle intelligence and IQ. It is capable of camouflage and is notoriously wicked and violent. It remains wary of Distortus Rex and, realizing it cannot win alone, has joined the alliance with Rexy, Spinosaurus, and Giganotosaurus.
