One interesting idea is that Hiro and Riza are sent back in time in the Princess Resurrection world. They have to adapt to the old ways and also find a way back to their own time. During this time - travel adventure, they might meet younger versions of the characters they know. This could create some really interesting dynamics in their relationship as they learn more about each other's pasts and the history of the world they are in.
One great fanfic could be about Hiro and Riza's adventure in the world of Princess Resurrection. Maybe they go on a quest to save the princess together. Their relationship could develop as they face various challenges, like fighting off monsters. They might start as friends and slowly realize their feelings for each other during the journey.
One idea could be that Hime and Hiro have to face a powerful new enemy together. They might discover a hidden power within their relationship that helps them defeat the foe. For example, a new type of magic that only activates when they hold hands or something like that.
One interesting plot idea could be that Reiri and Riza have to team up to save the princess from a powerful dark force. They might face various challenges along the way, like difficult magical barriers or dangerous monsters. Another idea is that there's a misunderstanding between them at first, but as they work together, they come to understand and respect each other more. Maybe they also discover a hidden power within themselves or a long - lost secret about the princess that helps in their quest.
One idea could be that Vanellope gets transported to Hiro's world. They team up to fix a malfunctioning microbot which has some sort of virus. Along the way, they learn about each other's worlds and skills.
Well, a possible plot for a Baymax x Hiro fanfic could be that they discover a new technology that is threatening the city. They have to work together, with Baymax using his medical knowledge and Hiro his technological skills, to stop the threat. It could also be interesting if there was a character from Hiro's past who returns and tries to drive a wedge between him and Baymax.
In this fanfiction, Reiri and Riza are the key players. Reiri could be someone who is fearless and bold, always ready to take on challenges directly. Riza, on the other hand, may be more cautious and calculating. Their different approaches to the situation of the princess' resurrection create a lot of the drama and development in the story. The princess serves as the focal point around which their actions and the entire narrative revolve. Without her resurrection being an issue, Reiri and Riza may never have crossed paths or had the interactions that drive the story forward.
One way to develop their relationship further is to introduce a conflict that they have to resolve as a team. Let's say there is a prophecy that only they can fulfill together. In the process of trying to understand and fulfill this prophecy, they would grow closer. They might start to see each other in a new light, not just as friends or allies, but as potential life partners.
One plot could be about them going on an adventure together to a mysterious land. They have to overcome various obstacles and in the process, they grow closer and discover new things about each other.
One idea could be that a human stumbles into Equestria and meets Princess Luna. Luna is initially suspicious but as she gets to know the human, they form a bond over their shared love for stargazing. Another could be a human who has the power to enter dreams like Luna, and they team up to fight a nightmare - inducing villain in both the human world and Equestria. Or perhaps a human artist who is inspired by Luna's beauty and grace, and through his art, he catches her attention and a friendship develops.
Maybe in the fanfic, the Resurrection Stone was never truly lost. It was secretly being protected by a group of centaurs in the Forbidden Forest. A young Hogwarts student stumbles upon this secret while exploring the forest. The centaurs test the student to see if they are worthy of handling the stone. If they pass, they are given the stone to use for a short time, but they must return it unharmed. This could lead to a series of adventures as the student tries to decide who to bring back, if anyone.
