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 idea could be a young ninja discovers an ancient and forgotten monster summoning contract. He then has to figure out how to use it without proper training, leading to some comical and dangerous situations. For example, he might accidentally summon a really small and useless monster at first, but over time, learns to summon more powerful ones.
One idea could be a story where a young and inexperienced ninja discovers an ancient slug summoning contract. They initially struggle to communicate with the slugs but gradually form a deep bond. Maybe they use the slugs' unique abilities, like their healing powers, in unexpected ways during battles.
Well, perhaps in the fanfiction, the female Naruto is an outcast in the village because of her dragon summoning contract. The village elders fear the power of the dragons. So, she has to train in secret with her dragon summons. They could go on adventures to different elemental lands to gain more power and knowledge. Along the way, she befriends other outcasts who also have unique abilities. And when the village is in real danger, she shows up with her dragon army to save the day.
It could be a new, young ninja who stumbles upon the cobra summoning contract by accident. This would be an interesting take as they start from scratch learning about the cobras and their powers.
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.
Perhaps the serpent contract in the fanfiction gives the wielder the power to communicate with all serpents in the Naruto world. This could lead to some really interesting storylines, such as using serpents to spy on enemy ninja. Also, the serpents could have their own hierarchy and politics, and the main character gets involved in their internal disputes while trying to use the contract's power for good.
Well, you could have a plot where a young, inexperienced ninja accidentally stumbles upon the crow contract. At first, he has no idea how to use it, but as he gradually learns, he forms a deep bond with the crows. These crows then help him in his various missions, and he has to keep their existence a secret from his village because some might see the power of the contract as a threat. Maybe there's also a dark force that is after the contract, adding an element of danger to the story.
One idea could be a story where Naruto discovers a hidden power within the Hawk Contract. Maybe it allows him to communicate with hawks in a unique way, like seeing through their eyes during battles. This would give him an edge in combat and spying on enemies.
A plot could revolve around a character who is initially afraid of snakes but is forced to enter into the snake contract. As they gradually overcome their fear, they start to understand the snakes better. They could learn unique jutsu from the snakes that are different from the ones Orochimaru used. For example, a jutsu that allows them to transform into a snake - human hybrid with enhanced speed and stealth. This could lead to a lot of internal conflict as the character struggles between their new power and the fear that still lingers within them.
A great fanfiction concept could be centered around a group of rogue ninjas who steal the snake summoning contract. They use the summoned snakes for their evil deeds, causing chaos in the ninja world. A young, inexperienced ninja team is then tasked with retrieving the contract. Along the way, they learn about the history and power of the snake summonings, and they also face moral dilemmas when they realize some of the snakes are not as evil as they seem.
