Well, you could write a fanfiction about a character who discovers a long - lost technique in an old karate manual and has to decide whether to share it with their dojo or keep it for themselves. Or perhaps a story where a Cobra Kai member has a change of heart after befriending someone from a rival dojo and tries to bring about peace between the two groups. Also, a plot about a female character breaking through the male - dominated world of karate in the Cobra Kai universe could be really interesting.
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.
A great plot for Cobra Kai fanfiction could be a character getting injured and having to find a new way to train and compete. This could involve exploring different forms of martial arts or training methods. Another idea is to write about the relationships between the students' families and how that affects their karate journey. For example, a student whose parents don't support their karate dreams but they still pursue it. And a fanfiction about a character who is secretly training at multiple dojos to combine different fighting styles would be quite engaging.
Maybe a villain from the future travels back in time to eliminate the Cobra Kai dojo before it even starts. This would disrupt the entire timeline of the series. The heroes would then have to figure out a way to stop this time - traveling villain and preserve the dojo's existence.
One idea could be an OC who is a new student at the Cobra Kai dojo. He has a unique fighting style that he learned from his travels around the world. This style catches the attention of both Sensei Johnny and Sensei Daniel, leading to a sort of rivalry between them over who gets to train the new talent.
One idea could be exploring the backstories of the minor characters in the Cobra Kai universe. For example, what was the life of that one student in the dojo who always seemed a bit lost? Another could be a time - travel story where a character goes back to the original Karate Kid era and tries to change things. Maybe they want to stop the rivalry between the dojos from ever starting.
In some 'naruto cobra summoning contract fanfiction', there could be a story where the cobra summons are connected to an old prophecy. The protagonist, by signing the contract, is thrust into a journey to fulfill this prophecy. They might have to overcome internal and external obstacles, like dealing with other ninja clans who are jealous of their new power and also understanding the true meaning of the prophecy which is hidden in the cobra's lore.
One interesting crossover could be Naruto characters learning the fighting styles of Cobra Kai. For example, Naruto himself might be intrigued by the aggressive and unorthodox methods of Cobra Kai. He could adapt some of their moves into his own ninja combat, creating a unique blend of shinobi and karate techniques. Another aspect could be the different philosophies clashing. The Cobra Kai 'strike first' mentality might be at odds with the ninja code of honor in Naruto, leading to some intense character development moments as characters from both universes interact and try to understand each other.
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.
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.
The mentorship aspect in Cobra Kai is a significant plotline. Johnny Lawrence becomes a mentor to a group of misfit kids at Cobra Kai. He tries to instill in them the values he believes in, which are different from the traditional Cobra Kai values in some ways. Meanwhile, Daniel also mentors his students in Miyagi - Do. The clashes and similarities in their mentorship styles add depth to the story. And the introduction of new characters like Miguel Diaz and his journey in Cobra Kai is also very interesting.
One idea could be exploring the Supreme Kai of Time's untold backstories. Maybe she had some secret training or a special encounter in the past that shaped her into the being she is in the DBZ universe.
One idea could be Kai getting infected by the dark matter and his struggle to regain his true self. He might have to face his inner demons while his friends try to find a cure.
