Maybe the dinosaurs are needed to help the superheroes save the world from a new threat.
To start writing dinosaur crossover fanfiction, begin with research. Learn about different types of dinosaurs, their behaviors, and habitats. Then, consider the other aspect of the crossover. If it's a crossover with a sci - fi world, think about how the science - fiction elements like advanced technology would interact with dinosaurs. Outline your story, including the beginning, middle, and end. For instance, start with a discovery of a portal that leads to a dinosaur world, then describe the adventures in that world, and finally how the characters get back home.
Next, create a plot that involves the main characters from both universes. It could start with a strange phenomenon that brings them together. Maybe a powerful shaman accidentally opens a portal to the One Piece world and has to team up with Luffy to get back home while also solving a problem in that world.
First, choose the fables you want to cross. Then, think about how the characters from each fable would interact.

First, decide which other show or universe you want to cross over with.

Maybe Jerry has to give a comedy workshop to the office employees.
First, decide which universe you want to crossover with. Then, study the lore and characters of both Twewy and the other universe.

First, decide which other universe you want to cross 'HxH' with. Then, study the lore and characters of both universes thoroughly.

Begin by creating an outline. Outline the main plot points, like how the characters will meet, what their initial reactions will be, and how they'll overcome their differences to fight the common foe. If you're doing a Trollhunters and 'Lord of the Rings' crossover, you might start with the Trollhunters being transported to Middle - earth. Outline how they'll interact with the hobbits, dwarves, and elves. Then, start writing your first draft, don't worry too much about making it perfect at first.
First, decide which other universe or story you want to cross the Akatsuki with. Once you've made that choice, research both the Akatsuki and the other world thoroughly. Then, come up with a basic plot idea. For example, if you're crossing with 'Harry Potter', maybe the Akatsuki are after a powerful magical artifact in Hogwarts. Next, create some initial character interactions. How would Sasori react to seeing a wizard use magic? After that, start writing your first draft, don't worry too much about making it perfect at first.
