One idea could be exploring the backstory of one of the minor characters in more detail. For example, the character who is the best archer in the group. You could write about how she came to be such a skilled archer, her training, and any personal challenges she overcame.
A relationship - focused fanfic could also be great. Maybe write about the friendship between two of the main characters that develops into something more. Show their growing affection for each other through shared experiences, like fighting side by side in a battle and then having a tender moment afterwards.
Another plot idea could be a time - travel fanfic. What if a modern - day woman somehow gets transported to the world of 'The Woman King'? She could bring new ideas and skills, and there could be a lot of interesting interactions as the women of the kingdom try to figure out this strange new arrival.
In this fanfic, a possible plot could be that Naruto, now a woman, decides to use her new form to her advantage in undercover missions. She could infiltrate enemy groups more easily as a woman. Also, her bond with her sensei Kakashi could change. Kakashi might have to adjust his training methods for her, and Naruto could learn different aspects of ninjutsu and strategy that were more suited to her new gender.
One idea could be a story about a young hero who discovers they have a special connection to the Dragon King. They embark on a journey to learn more about this connection and in the process, they face various challenges like battling dark forces that oppose the Dragon King's reign.
One idea could be creating an OC (original character) who is a long - lost relative of Simba. This OC could arrive in the Pride Lands with a unique skill, like being able to communicate with a different type of animal that the lions usually don't interact with. For example, a small rodent that has knowledge of a hidden danger approaching the Pride Lands.
In a 'a king without a crown fanfic', the king might be cursed to never wear the crown again. So, he focuses on building relationships with neighboring kingdoms on a personal level rather than through diplomatic formalities. His charm and wisdom begin to earn him respect from other rulers, and he starts to form alliances that could potentially help him break the curse and reclaim his crown.
One idea could be that Naruto discovers a hidden power within himself that allows him to communicate with the Monster King. They form an unlikely alliance to fight a common enemy, like an ancient evil that threatens both the ninja world and the monster realm.
One idea could be that the new king has to face a hidden conspiracy within the world of 'Unordinary'. Maybe some powerful groups are trying to undermine his rule from the start. Another could be that the new king discovers a long - lost power that changes the balance of power in the 'Unordinary' universe. He then has to decide how to use it for the good of all.
One idea could be that Ariel discovers a long - lost power within herself and King Triton has to help her control it. Maybe it's a power that could potentially save the underwater kingdom from a new and mysterious threat.
One idea could be that the male OC is a traveler who stumbles upon the gypsy woman's camp. He's initially met with suspicion but as he proves his good intentions, they form a bond over shared stories of their different cultures. Another could be that the gypsy woman has a special power and the male OC gets caught up in helping her protect it from those who would misuse it.
One idea could be a misunderstanding. Maybe some false information makes Batman think Wonder Woman has been compromised and he has to stop her. Another could be a competition for a powerful, mysterious artifact that they both believe they should safeguard. And a third idea could be a mind - control situation where Wonder Woman is being controlled by an enemy and Batman has to fight her to break the control.
A fanfic could explore a scenario where Batman is framed for a crime on Themyscira. Wonder Woman doesn't believe he's guilty and they have to work together to clear his name while also uncovering a conspiracy within her own homeland that threatens both their worlds.
