Well, a plot could be that a human discovers a baby T - Rex and decides to raise it. As the T - Rex grows, they face many challenges together. The human has to teach the T - Rex how to survive in a world that is not entirely its own. Or perhaps in a post - apocalyptic world where dinosaurs have been brought back to life, a group of humans led by one brave individual has to negotiate with a T - Rex tribe to share resources. Also, a story where a human is magically linked to a T - Rex's mind and they have to experience each other's worlds.
One idea could be a time - travel scenario where a human goes back in time and has to interact with a T - Rex. Maybe the human has to find a way to communicate with it to prevent some sort of prehistoric disaster. Another could be a story where a T - Rex is brought to the modern world through some scientific experiment gone wrong, and a human befriends it and tries to protect it from those who want to harm it. A third plot could involve a world where dinosaurs and humans coexist, and a human and a T - Rex form an unlikely alliance against a common enemy.
Some interesting plot ideas for T Rex x Human fanfiction could start with a human archaeologist who stumbles upon a hidden valley where T - Rexes still exist. The human tries to study them without getting eaten. Another could be that a genetic experiment creates a half - human, half - T - Rex hybrid, and the story follows their struggle to find their place in both the human and dinosaur worlds. And a more comical plot could be a T - Rex who accidentally gets shrunk and a human has to take care of it, like a tiny, dangerous pet.
Perhaps a post - apocalyptic world where an Indominus Rex and a group of humans form an unlikely alliance. The Indominus Rex, being a powerful predator, helps the humans fend off other dangerous dinosaurs in exchange for food and shelter. The story could explore the trust and fear dynamics between the two species.
A possible fanfiction plot could be that a female T - Rex gets transported to a modern - day city through a time - space rift. A kind - hearted human takes it upon themselves to help the T - Rex adjust to this new world. The human teaches the T - Rex about things like traffic lights and supermarkets, and in return, the T - Rex uses its strength to protect the human from bad guys. Or perhaps in a fantasy world, a female T - Rex is a magical creature and a human is a wizard. They meet and join forces to defeat an evil dark lord who wants to enslave all the magical creatures in the land.
Maybe a 'a t rex life fanfiction' where a T - rex forms an unlikely friendship with a smaller dinosaur. The T - rex protects the small one from other threats, and in return, the small dinosaur helps the T - rex find the best places to hunt or warns it of approaching danger. It could show how different species can co - exist in the dinosaur world.
Maybe a fanfic where Rex discovers a hidden talent of Breach that no one else knew about. For example, Breach is an amazing artist but has been hiding it. Rex encourages Breach to show it to the world, and through this process, their relationship blossoms. It could also involve some challenges from the other members who don't believe in Breach's new - found confidence.
One idea could be that Mythra and Rex have to team up to save their world from a new, powerful enemy. During their journey, they discover new powers within themselves and also realize their feelings for each other are deeper than they thought.
One interesting concept could be the physical appearance of the hybrid. Would it have the large, powerful body of a T - Rex with some human - like features? Maybe it has human - like hands or eyes. Another concept could be the behavior. It might combine the predatory instincts of the T - Rex with human intelligence and morality, leading to some complex internal struggles.
Survival is a common theme. Since a T - rex is a large and dangerous predator, the human character often has to find ways to survive in the presence of the T - rex.
The relationship can be developed through mutual need. For example, if the human is lost in the dinosaur's territory, the T - Rex could initially see the human as prey but then realize the human has some unique skills, like making fire or using tools. This could lead to a truce. Or if the T - Rex is injured, the human could use their medical knowledge (assuming some sort of knowledge transfer in the story) to help the T - Rex, and in return, the T - Rex protects the human from other threats.
One plot idea could be that Rex's nanites start to interact strangely with the eezo in the Mass Effect universe. This causes unforeseen effects like creating new forms of biotics or causing glitches in mass relays. Another idea is that Rex is mistaken for a new species and is studied by Cerberus, who want to use his nanites for their own evil purposes. He has to escape and team up with Shepard to take down Cerberus once and for all.
One plot idea could be a human scientist studying Skullcrawlers in their natural habitat. The human accidentally gets separated from their team and has to rely on their wits to survive among the Skullcrawlers. Maybe they discover that the Skullcrawlers have a complex social structure that was previously unknown. Another could be a story where a human is befriended by a young Skullcrawler that is an outcast in its group. Together, they face challenges from both the Skullcrawler community and humans who fear the unknown bond between them.
