What are some interesting plot ideas for King Ghidorah crossover fanfiction?

One idea could be a story where Godzilla and King Ghidorah have to team up against an even greater threat from outer space. This would force their natural enmity aside as they realize the common danger.

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 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.

If it's a crossover with the Power Rangers, the Rangers themselves would be obvious choices. They could combine their Zords and powers to take on King Ghidorah. Each Ranger could use their unique skills and weapons to try and damage the three - headed monster.

One possible plot could be about how the other kaiju react to King Ghidorah's pregnancy. Maybe Godzilla would be initially shocked and then start to consider if this new situation changes the power balance among them.

Well, perhaps Harry discovers he has some hidden power that is related to King Ghidorah. Maybe he can transform into King Ghidorah - like form in times of great danger at Hogwarts, using his new - found abilities to protect the school from dark wizards. The other characters would be both amazed and a bit scared of this new Harry.

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.
