The plot might revolve around the challenges King Ghidorah faces during the pregnancy. It could be that the physical changes due to pregnancy make it difficult for it to fly or use its powers as effectively. And there could be other creatures in the Monsterverse that see this as an opportunity to either help or take advantage of King Ghidorah's weakened state.
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.
In the world of fanfiction, it could be another powerful kaiju. Maybe a new, mysterious kaiju that was introduced into the Monsterverse secretly. This new kaiju could have some special abilities that were passed on to King Ghidorah's offspring.
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 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.
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.
In a King Ghidorah x Mothra fanfiction, a possible plot could be that King Ghidorah is somehow injured and Mothra, being the more benevolent of the two, decides to heal him. As she heals him, she also tries to change his evil ways. This could be a story of redemption for King Ghidorah, and how Mothra's kindness can have a profound impact on even the most evil of creatures.
Well, a fanfiction could be set in an alternate universe where King Ghidorah and Mothra are the last two of their kind. They have to find a way to repopulate their species, but their natural instincts are so different. King Ghidorah is more about destruction and dominance, while Mothra is about life and harmony. This conflict could be the central theme of the story, exploring how they try to overcome their differences for the greater good of their species.
Perhaps there could be a sub - plot where Rafiki plays an important role. He could be the one to predict the gender of the cub based on some ancient signs or rituals. And he might also give Nala some special advice on how to keep the cub healthy during the pregnancy.
One common theme is the power struggle. Given King Ghidorah's already formidable nature, in fanfiction with a female version, there might be a focus on how she wields her power, whether it's against other kaiju or in a more complex political or social structure within the kaiju world. Another theme could be redemption. Maybe the Female King Ghidorah starts off as a villain but then has a change of heart.
The main events in the King Ghidorah story include its initial appearance on Earth, which is always a big deal as it brings destruction. Then there are the numerous battles it has with Godzilla and other kaiju. Sometimes, there are also events where humans try to interfere with its actions, either to stop it or to use it for their own purposes.
Well, one possible plot could be that Natsu, as the king, has to deal with the political implications of Lucy being pregnant. He might face challenges from other kingdoms who see a potential heir as a threat. And Lucy, as the queen, could be struggling with her new role and the physical and emotional changes of pregnancy.
