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 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.

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 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.

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 a crossover with a popular anime like 'Naruto'. Imagine the fighters from 'King of Fighters K' having to battle the ninjas. They could learn new skills from each other. For example, Kyo could learn some shadow clone techniques and use it in his fight style. Another idea is a crossover with a classic video game like 'Super Mario'. The 'King of Fighters K' characters could be in the Mushroom Kingdom and have to deal with Bowser while also facing their own rivals.

Maybe a crossover with a magical anime. The nanbaka characters could suddenly find themselves in a world full of magic. Some of the nanbaka characters might be really good at using magic in unexpected ways, like Jyugo using his shackles in a magical battle.

A crossover with a modern - day action story could be really cool too. Spartacus and his crew could be brought to the present day through some time - travel mishap. They then have to navigate the modern world, learning about new weapons and technology. They could use their ancient fighting techniques in modern combat situations, like taking on a powerful criminal organization.

Maybe in the fanfiction, the three - tailed beast crosses over into a modern - day human world. People initially fear it, but then they discover that it has a gentle side and is actually trying to find its way back home. It could form a bond with a group of humans who help it on its journey, leading to many adventures along the way.
