Perhaps they could face some family drama. Like, Kai's over - protective family visits and they have different ideas about how Kai and Hilary should live their lives. Hilary has to prove herself to them and in the process, Kai and Hilary grow even closer as they support each other through this difficult time.
A plot could involve Kai getting lost in a strange place after a beyblade battle goes wrong. Hilary goes to look for him and finds him. They are then stuck in that place for a while. During this time, they have to rely on each other to survive. Hilary's determination and kindness start to break through Kai's tough exterior, and they form a deep bond that turns into love.
Another alternative is that they could participate in a sports competition together. Kai could be the athlete, and Hilary could be his coach or supporter. They would train hard, face tough opponents, and during the process, they strengthen their relationship. There could be moments of doubt, encouragement, and ultimately victory or learning from defeat, which would be a great positive plot for fanfiction.
Another plot could be about their wedding planning. Since they are from different backgrounds, there could be cultural clashes. For example, Cinder might have some traditions from her side that Kai's people find strange, or vice versa. And they have to find a way to incorporate both cultures into their big day while also making sure their families and kingdoms are happy. It could be a really sweet and comical story as they struggle with things like choosing the right wedding dress or the proper ceremony format. Also, there could be some jealous suitors from the past who resurface and try to break them up, adding some drama to the story.
In the fanfiction world, their marriage could be a way to bring two different personalities together. Kai is strong - willed and focused on Beyblade, while Hilary is more nurturing. Their wedding could be a symbol of how different types can find harmony. Maybe they have a destination wedding on a beach. The sun sets as they say their 'I dos', and their friends cheer them on. This would be a beautiful moment for fans who ship them.
In this fanfiction, they could face challenges together. Maybe there are some people who don't approve of their marriage. But they would overcome these obstacles through their love and determination. They would prove that their relationship is strong and that they are meant to be together, whether it's in the Beyblade arena or in their personal lives.
One idea could be a time - travel plot where a character goes back to the original Karate Kid era and tries to change the events that led to the Cobra Kai dojo's current state. Another could be a story focused on a new student at the Cobra Kai dojo who has a unique fighting style that challenges the traditional teachings. Maybe a fanfiction where two rival characters from different dojos have to team up to face a common enemy outside of the karate world.
One great Kai and Hilary fanfiction is 'The Journey Together'. It focuses on their adventures in a magical world. They face various challenges and in the process, their relationship deepens.
One idea could be that Tyson and Hilary get lost in a mysterious Beyblade tournament location. They have to work together to find their way out while also facing some tough opponents. Another plot could be a story where Hilary discovers a new Beyblade technique and she and Tyson train together to perfect it for an upcoming big match.
Another plot could involve the main character in the fanfiction realizing that they got married too young and now they are having second thoughts. This could lead to a series of self - discovery and relationship - testing events. For example, they might meet someone new who makes them question their marriage, but in the end, they realize the value of their relationship.
One idea could be a story where Kai and Aichi go on a journey through a magical lemon grove. In this grove, they discover that the lemons have special powers that can heal the broken relationships in their world. Another could be a modern - day AU where they run a lemonade stand together and through that, they learn more about each other's dreams and fears.
