REXS

In the year 3198, Humanity has recreated the dinosaurs and scientists have kept them in a safe environment, but sadly with global warming and Eco-terrorist using some of the dinosaurs the cities are destroyed and humanity has wiped itself out. Androids are still around, but without their masters, they pick up and clean the remains of their homes due to their default settings, one such android ( named 73k2, Sev for short) is in a lab looking after three Rex eggs. On January 3 the eggs hatch, Zeus ( the yellow accurate T-Rex), Hades ( a black mutant Rex with a bulbous forehead head, two massive three-fingered forearms, and two small arms to hold objects), and Poseidon ( a white hybrid Rex part velociraptor for smart, Saurophaganax for claws, shrew for teeth and venom, ape for arms and tools, dwarf crocodile for body armor and stronger tail) hatch and imprint on Sev who helps teach them to hunt. For a while, the Rexs hunted near the lab where they hatched, but after 30 years it eventually fell to rubble forcing them to move further into the surrounding jungle. While they traveled they learned about the new wildlife (wolves, bears, foxes, deer, etc) and eventually ran into an ambush set up by a pack of Carnotaurus ( small, accurate pack hunters that use green scales to ambush their prey), but they manage to escape and go out into the desert where they spent a cold night.
While they traveled along the border they ran into a pack of Utharaptors (white feathers) and were once again chased away, but after they escaped they discovered an oasis with a cave right in the border and Sev helped them build a nest. The next morning the Carnnotaurs and Raptors find them and Zeus, not wanting to lose his home, steps up to defend it. Zeus initially struggles, but when Sev gets hit by the Carno's tail he goes berserk throwing the raptor on the Carno and biting down hard, decapitating the Carno and simultaneously cutting the Raptor in half, and with his brothers' help driving out the predators. Sev is proud of the accomplishment but confesses that maybe Zeus should show respect to the other predators, saying there are no bad guys, this prompts Zeus to send Hades to check on the predators at a safe distance, where he sees both sides teach their young how to hunt, their teamwork, and when they peacefully drink alongside prey. Wanting to go to the waterhole Poseidon suggests a peace offering and recalling the predators eat fruit for treats, they make a fruit basket with a camel and boar and bring to the waterhole to announce their peace.
While initially hesitant the predators accept the offering and respect each other's boundaries and peace is established. On April 5 the Rexs smell something new, sea salt, and by following the scent they find a shore and discover the symbiosis between three spinosaurus and a mosasaur ( both blue and accurate) when they work together to attack and eat a grey whale. By keeping track of the Spino's routes they find a rocky cliff far from their borders, seemingly adding a new part to their territory and gaining access to fish food. With Hades and Sev on the shore, Zeus and Poseidon go out for a swim and rest on a rock, but their trip is interrupted when they are attacked by a Cetusdraco ( a genetic hybrid, tylosaur as base, Livyatan for size/teeth, orca for intelligence, beluga for echolocation, mako for speed/gills, and X-ray fish with transparent fins) and the due barely make it back to avoid getting eaten, but just when they are about to leave they witness the Spinos and Mosa hide when the Cetusdraco goes near the shore, which gives Sev and Zeus an idea. The next day the Rexs cautiously approach the Spinos and explain that they have a common enemy and that they have a plan, using Hades as bait the lure the Cetusdraco into shallower waters, and when it is about to strike they ambush it, tear off it's fins, and drown it in deep water, successfully killing it earning the Spino's respect, and sharing the carcass equally.
The next day, curious about what was at the other end of the beach the brothers travel down until they hit a fog, where they run into a quetzalcoatlus flock that chases them into their massive nesting grounds, which they share with Pterodactyls and pteranodons, where the massive leader orders an attack on the brothers, but they reach safety when they find a cave where an albino pteranodon, named Terry, who explains that the world is massive and full of many creatures. That night when they returned they asked Sev about the humans and learned about how god created all life, the dinosaurs' extinction, the human domination and self-destruction, and finally their rebirth, Zeus wonders where the humans are believing some survived the chaos. on September 15 the brother feels an unknown urge, which they ask Sev and learn about the mating season, after which they witness the Carno's jousting and arms displays and the Raptor's fight. When they go to the beach they arrive just in time to join the Spinos in their migration joining a herd of herbivores (all Accurate), Brachiosaurs, iguanodons, triceratops, and pachyrhinosaurus, and the journey takes them to Central America, Where they meet the red-crested Allosaurs and a pair of Giganotosaurus (Both accurate). The Brothers and Sev befriend their fellow carnivores by creating a coordinated attack on a brachiosaurus, Allosaurs attack on the side as a distraction, while the Rexs ambush from the trees, and the Gigas successfully drag down two sauropods over a small ledge leading to a massive feast.
On November 25 the brothers feel the urge again and go into the jungle where they find a group of females (accurate, smaller with feathers on their backs), but discover that they are being cruelly treated by Tusk, a T rex with tusk-like snaggle-teeth who kills for sport, which prompts Zeus to step up and fight back and though he struggles at first he wins, but lets a wounded Tusk go to let him die peacefully. After mating with the females the brothers and Sev return home, but then they discover the ruins of Indianapolis and learn from the Watchers ( tall androids who search the streets for crime) that there is a human village nearby. The next day the brother calmly walks through the village much to the humans' shock, but with Sev helping translate they mean no harm and leave peacefully with the hope that one day the humans and Rex can coexist peacefully. 2 years later we see the descendants of the brothers hunting side by side with humans, meaning Zeuses wish is fulfilled.The End
