For Dinosaur King Crossover Fanfiction, here's a plot. There could be a crossover with Sailor Moon. The Sailor Scouts and the Dinosaur King characters meet when a dark force is trying to use the power of the dinosaurs and the magical powers of the Scouts. They must combine their strengths to defeat this evil. Another plot could involve a crossover with Yu - Gi - Oh! The Dinosaur King characters enter the world of Duel Monsters and use their dinosaurs as a new type of card. And one more idea is a crossover with Dragon Ball Z. The Dinosaur King characters train with the Z - Fighters to gain new powers to fight a powerful villain who is interested in the dinosaurs' unique abilities.
One idea could be a crossover with Pokémon. The Dinosaur King characters could travel to the Pokémon world and have battles with Pokémon trainers using their dinosaurs. Another idea is a crossover with Digimon. The digital world could intersect with the Dinosaur King universe, leading to unique adventures. Maybe the Dinosaur King characters have to team up with Digimon to defeat a common enemy.
Well, a fun dinosaur crossover fanfiction could involve dinosaurs and aliens. Maybe an alien race discovers Earth during the time of the dinosaurs and tries to either study or conquer them. This could lead to an epic battle between the two very different species. Or perhaps the aliens genetically modify the dinosaurs to create super - dinosaurs to do their bidding.
One idea could be that the female OC discovers a new type of dinosaur that has unique powers. This could lead to a race against the villains in Dinosaur King to either protect or control the dinosaur. Another plot could involve the female OC being from a different time period and having to adjust to the present world while also using her knowledge of dinosaurs to solve various problems.
One idea could be a crossover with Godzilla. King Ghidorah teams up with some other kaiju to take on Godzilla in an epic battle across multiple cities. They could use their different powers in unique ways, like King Ghidorah's gravity beams against Godzilla's atomic breath.
One idea could be that the protagonist, reincarnated as a dinosaur, tries to prevent the extinction event. They could use their human knowledge to find a way to survive the impending asteroid or environmental changes.
One idea could be Godzilla teaming up with other kaiju from different universes to fight a common, powerful enemy. Maybe an alien force that is threatening all kaiju-kind.
One idea could be that the Turtles from 1987 end up in the 2003 universe and have to adapt to the darker and more serious tone. They could team up with the 2003 Turtles to fight a common enemy like the Shredder. The 1987 Turtles' more light - hearted and comical ways might initially clash with the 2003 Turtles' brooding nature, but they eventually learn from each other.
One idea could be a crossover with Undertale. The characters from Glitchtale could interact with the original Undertale characters in a new and unexpected way. For example, Betty from Glitchtale could team up with Chara from Undertale for some sort of dark plan. Another plot could involve a crossover with a different game like Minecraft. The Glitchtale characters could find themselves in a blocky world, having to adapt to new rules and enemies. Maybe Sans from Glitchtale could use his powers in the Minecraft world in a really creative way.
A great plot idea would be Android 21 crossing into a world where technology is feared. She'd have to prove that not all advanced technology is bad. Also, she could cross into a world of pirates, using her skills to navigate the high seas and fight off other pirates.
A plot idea could involve a magical crossover. Maybe a character from a magical fanfiction world accidentally enters the Wayside School. This could lead to chaos as the normal rules of the school are disrupted. The students might have to learn about magic to help the new character return home, and in the process, they gain some magical abilities themselves for a short time. This could also create new friendships and rivalries among the characters.
