One possible plot idea could be exploring how the park staff in Jurassic World reacts to the discovery of the pregnant Indominus Rex. They might be in a panic, trying to figure out how it got pregnant in the first place, perhaps suspecting some unauthorized genetic tampering within the park.
One possible plot could be about the challenges of protecting a pregnant Indominus rex. Maybe the park staff in a Jurassic World - like setting have to ensure her safety from other dinosaurs and also deal with the mystery of how she got pregnant. They might have to create a special enclosure for her and face unexpected difficulties during her pregnancy.
One possible plot could be that the human male is a scientist who, against all odds, tries to understand the Indominus Rex's behavior. He might start by observing it from a distance in its enclosure. As he gets closer, he discovers that the Indominus Rex has an unexpected level of intelligence. This could lead to a series of events where the two form an unlikely bond, and the human male has to protect the Indominus Rex from those who want to destroy it due to its dangerous nature.
The main character could be a young and brave paleontologist who is intrigued by the pregnant Indominus rex. This person would be constantly observing her, trying to understand her behavior during pregnancy and writing detailed reports about it.
Another challenge would be the reaction of the other dinosaurs in the park. They may sense the pregnant Indominus Rex as a threat or an opportunity, which could lead to a lot of chaos and fighting. This would make it hard for the Indominus Rex to find a safe place to give birth.
Well, the plot could involve the Indominus Rex, being a powerful and somewhat menacing creature, falling for a dragon which is also a very majestic being. Maybe they meet in a strange, prehistoric - fantasy hybrid world. The Indominus Rex could be initially intrigued by the dragon's ability to fly and spit fire, and the dragon might be curious about the Indominus Rex's unique genetic makeup. They could start off as rivals, competing for territory or resources, but gradually develop feelings for each other as they discover each other's strengths and vulnerabilities.
A possible plot could be about a baby Indominus rex being found alone in the wild. A group of scientists discovers it and decides to take it in. They try to raise it in a controlled environment, but the baby Indominus rex has a wild and unpredictable nature that causes all sorts of chaos and challenges for the scientists.
One idea could be an Indominus Rex crossover with the Jurassic Park raptors. The Indominus Rex could form an uneasy alliance with the raptors against a common threat, like a new genetically engineered dinosaur that's even more dangerous. This would create a lot of tension and interesting power dynamics.
One idea could be a story where Godzilla and Indominus Rex are forced to team up against a common, even more powerful enemy. Maybe an alien invasion that threatens to destroy their world. They start off as enemies but gradually learn to work together.
One possible scenario in such a fanfiction could be that Harry discovers his unique Animagus form of Indominus Rex during his time at Hogwarts. Maybe it's a result of some dark magic experiment gone wrong in the Forbidden Forest that alters his magical core and gives him this fearsome form. He would have to hide it from his friends and teachers at first, fearing the consequences.
In this fanfiction plot, the Indominus Rex could be a long - lost ancient magical creature that was hidden in the Muggle world for centuries. When it resurfaces, it causes chaos. Harry Potter, along with Hermione and Ron, start researching about it in the Hogwarts library. They find out that it has a connection to an old wizarding family. They then have to find the descendants of that family to see if they can control the Indominus Rex and restore peace in both the wizarding and Muggle worlds.
