One idea could be that Wolf and Virginia get separated from the group again in a new magical land. Wolf has to use his wolf - like instincts to protect Virginia from unknown creatures. Another could be a story where they go back in time within the 10th Kingdom and have to change a certain event to save the future of the kingdom, all while their relationship deepens.
Perhaps a fanfiction where Wolf discovers a new power within himself, and Virginia has to help him control it. They could be on a quest to find a wizard who can teach Wolf how to use this power properly. Along the way, they face challenges that test their loyalty to each other and to their friends in the 10th Kingdom.
One idea could be exploring the backstories of the minor characters in the 10th kingdom. Maybe a story about the life of a random villager and how the events of the main story affected them.
Well, if they start to learn more about each other's pasts, it can deepen their relationship. Maybe Wolf reveals more about his life as a wolf - man before he met Virginia, and Virginia shares her dreams and fears. This new level of understanding can lead to a more profound emotional connection between them. Also, if they have to make sacrifices for each other, like Wolf giving up his freedom for a while to save Virginia or vice versa, it would show the depth of their love.
One idea could be exploring the backstories of the new characters introduced in Kingdom Hearts 3 in more depth. For example, you could write about how they came to be in the different worlds and what their true motives are.
A great plot could be about a female character from 'last kingdom fanfiction' who disguises herself as a man to join the army. She then has to constantly hide her identity while also dealing with the challenges of war and her growing feelings for one of her comrades.
One idea could be that Bella discovers she has a special power that only she can use to protect the wolf pack. For example, she might be able to communicate with the spirits of the forest which give her warnings about upcoming threats.
Well, in some fanfiction, the plot might involve the wolf being a part of a prophecy related to Hermione. For example, it could be foretold that only she can save the wolf from an impending doom, like a dark magic that is slowly consuming it. This would lead her on a journey to find a cure or counter - spell. Also, the wolf could be a link to Hermione's past that she was unaware of. Maybe it was somehow connected to her family's hidden magical heritage, and as she gets to know the wolf, she uncovers long - lost family secrets.
Perhaps the black wolf is actually a cursed prince and the fanfiction could focus on his journey to break the curse. He might meet a kind-hearted maiden who helps him along the way.
Perhaps the 8th Hokage has to deal with internal political unrest within the Hidden Villages. Some ninjas might be unhappy with the new leadership and try to undermine the 8th Hokage's authority, leading to a complex web of intrigue and conflict.
One idea could be that the Heartless somehow find their way into the Marvel universe and start attacking various locations. The Avengers, being the protectors, team up with Sora and his friends from Kingdom Hearts. They initially have some clashes due to different fighting styles and ways of understanding the world, but eventually learn from each other and combine their powers to defeat the Heartless. For example, Iron Man could use his technology to analyze the Heartless' weaknesses, while Sora uses his Keyblade to directly combat them.
One idea could be that Sora finds himself in a new world where he is surrounded by characters from different Kingdom Hearts realms who all have a strong attraction to him. They compete in a friendly way to go on adventures with him.
