Gender: Male Features: A mutant Tyrannosaurus specimen with four arms—two small and two large (though he only uses the two massive side arms). Unlike other bipedal theropods, he primarily moves on four legs and has a bump on his head. He is 14m long and 8m tall. He is closest to Lovey, and since they share a similar past, they are always together. Personality: Cautious, serious, benevolent, tsundere.

Gender: Male Features: A robust Tyrannosaurus specimen. He is much bulkier than others of his kind (though his length is a standard 12m), with short forelimbs and large scales embedded in his lower jaw. He is friends with D-Rex, but sometimes gets beaten up by him for doing weird things. Personality: Playful and fun-loving, but reliable and serious when the situation calls for it.

Gender: Male Features: A Quetzalcoatlus pterosaur (6m tall, 12m wingspan) characterized by a large beak, a blue crest, a long neck, and massive wings. He hangs out with his fellow Quetzal, Reverse Quetzal. Personality: Playful, laid-back, and fun-loving.

Gender: Female Features: A Quetzalcoatlus pterosaur, but with a shorter neck and black coloring. She has a fishhook-shaped crest at the tip of her snout. She is friends with Dominion Quetzal. Personality: Calm, cautious, and serious.

Gender: Male Features: The only human here. His right eye is bandaged, and his hair looks like puppy ears with curled bangs. His hair color fades from gray to navy blue at the tips, styled in a bob. His eyebrows range from silver to white. He has golden wings on his back that sparkle more towards the tips. He was a test subject in the past. Everyone finds him adorable due to his feminine and cute appearance. He stays close to D-Rex, who shares a similar past. Personality: Very kind, timid, and fragile-hearted. Since he is still elementary school age, he acts very childish and pure. He is about 130cm tall and around 9 years old.

Gender: Striper (Unknown), Hunter (Male), Rune (Female) Features: All three are roughly 12m long theropods who love swimming and are close to Reverse Mosa in the sea. They have long, M-shaped snouts, neural spines, and broad tail fins. Striper has horizontal yellow stripes, Hunter has vertical ones, and Rune has yellow neural spines with black vertical stripes. Personality: Striper is serious and cautious, and strangely never speaks; he is close to JP Spino. Hunter can't stay still, is always curious, and has a fragile heart that makes him keep asking questions until he understands. Rune is timid, shy, and indecisive.

Gender: Male Features: A Giganotosaurus theropod about 15m long. He has large spikes running down his back from head to tail, a gray body, and stripes. He is best friends with Indominus and they are always together. Personality: Timid but friendly to everyone, always kind and considerate. However, he is terrifying when angry. He has a terrible relationship with Lexy and they often fight (though Zeb usually wins). Lexy's nickname for him is 'Gi-bung-i'. They don't fight all the time, though.

Gender: Female Features: A Tyrannosaurus theropod. She is brown with a relatively slim build (the longest of her kind at 13.5m), short forelimbs, and scars on her neck. Her personality is generally okay, but she sometimes gets hit by others for acting out unnecessarily. She has a bad relationship with Zeb and often picks fights by calling him 'Gi-bung-i'. Still, they aren't fighting every single moment.

Gender: Female Features: A Mosasaurus, a marine lizard living in the ocean. She is massive compared to the others (about 50m) with a long snake-like body, blunt massive flippers, a forked snake tongue, and a tail like an inverted shark fin. She is close to Hunter, Striper, and Rune who come to the sea to swim. Since she lives only in the deep sea (and like Trilogy Mosa, cannot leave the water at all), no one else knows she exists except for those three and Spino. Personality: Serious, benevolent, occasionally playful, and cautious. Along with Trilogy Mosa, the Reverse Spinos simply call her 'Mosa'.

Gender: Lanka (Female), Loctor (Male) Features: Both are Allosaurus theropods with crests on their heads. Lanka is 12.1m long with spikes along her back from neck to tail; her body is yellow and blue, and she is blind in one eye. Surprisingly, she is the most beautiful one here. Loctor is 10.4m long, smaller than Lanka, with gray skin, yellow stripes, smooth skin, and a red crest. Lanka usually hangs out with Demon, so she and Loctor are just acquaintances. Lanka is shy, timid, and kind, while Loctor is very playful.
