Another interesting concept is a time - travel fanfic. A character somehow gets sent back in time to the pre - historic era where the dinosaurs actually lived. They have to survive in that world and try to find a way back, while also witnessing the true nature of the dinosaurs without the modern - day park's infrastructure.
One idea could be exploring the post - Dominion world where dinosaurs are now fully integrated into society. Maybe a story about a family who has to adapt to living next to a T - Rex nesting ground. It could be full of comical and heartwarming moments as they learn to coexist.
Well, a jurassic world crossover fanfiction might involve crossing it with 'Doctor Who'. The Doctor could land in the Jurassic World and have to figure out how to stop a time - related disaster involving the dinosaurs. Or a crossover with 'Lord of the Rings', with the hobbits and other characters encountering dinosaurs in Middle - earth. A crossover with 'Supernatural' could also be cool, where Sam and Dean hunt down a demon that's using dinosaurs as its minions.
Another idea is an OC who is a park ranger with a special connection to the dinosaurs. Maybe they grew up around them and have an almost instinctive understanding of their behavior. This character could be involved in a plot where they try to prevent a group of poachers from stealing dinosaur eggs. It would be full of action and suspense.
One idea could be that Hogwarts students take a field trip to Jurassic World. The wizards and witches might be fascinated by the dinosaurs, but then things go wrong when a dark wizard tries to use magic to control the dinosaurs for evil purposes.
One idea could be creating a new hybrid dinosaur that has unique abilities, like the ability to camouflage itself. Another idea is to write about a group of dinosaurs that have formed an alliance to survive in the park. Maybe a T - rex and a triceratops working together against the humans who want to control them.
One interesting crossover could be the Avengers having to deal with the dinosaurs in Jurassic World. Maybe Iron Man uses his technology to try and control the dinosaurs or Thor uses his powers to fight off the really big ones like the T - Rex. It would be a really chaotic but exciting scenario.
Another storyline could be an OC who is a park ranger with a mysterious past. This ranger discovers a hidden part of the island that has dinosaurs not previously known to the park. They then have to figure out how to keep this discovery safe from those who might want to exploit it for profit or use the dinosaurs for illegal activities. This could lead to a race against time to protect these new dinosaurs and their habitat.
One idea could be exploring what would happen if the dinosaurs developed a form of communication with humans. For example, a velociraptor that tries to warn the park workers about a hidden danger in the park.
One idea could be a crossover with 'Alien'. The dinosaurs in 'Jurassic World Fallen Kingdom' could be on a remote island where an alien spacecraft crashes. The dinosaurs and the aliens then have to face off against each other. It would be a battle of two very different but equally dangerous species.
Owen Grady would be an obvious and interesting choice. His skills with dinosaurs and his connection to Blue could be further explored. For example, he could be on a mission to rescue Blue from a new threat in the post - Dominion world.
