One possible plot could be that Natsu and Naruto, as brothers, grow up in a world where magic and ninjutsu co - exist. They start off training together, with Natsu teaching Naruto some basic fire - based magic and Naruto showing Natsu his ninja skills like tree climbing. As they grow older, they face a common enemy that threatens both their worlds. They combine their powers, Natsu's brute strength and fire magic with Naruto's strategic ninjutsu and shadow clones, to defeat the enemy and save their loved ones.
The plot could involve Natsu and Naruto finding out they are brothers in a rather unexpected way. Maybe there's a mysterious prophecy that says two boys from different realms will come together as brothers and bring balance. They initially don't believe it but as they start to interact, they realize they have a lot in common. They then embark on a journey to discover their true heritage. Along the way, they meet other characters from their respective universes, like Natsu's Fairy Tail friends and Naruto's Konoha comrades. They have to overcome differences in culture and power - systems to truly become a united front against the forces that oppose them.
Natsu's fire magic could enhance Naruto's fire - based jutsu. For example, if Naruto uses his Fireball Jutsu, Natsu could add his own magical fire power to make it even more powerful. Also, Naruto's shadow clones could be used in interesting ways with Natsu's fighting style. Natsu could use the clones to his advantage, like having them distract an enemy while he charges in with a powerful fire punch.
One interesting plot could be the brothers facing a powerful new enemy together. They might have to combine their unique ninja skills to defeat this foe.
Well, the two brothers would obviously be the main characters. Their names might be Naruto and Natsu, though it's a fanfic so the author could give them some unique twists to their personalities compared to the original Naruto series.
Well, it could be about Naruto somehow ending up in the Fairy Tail world and meeting Natsu. Maybe they team up to fight a common enemy. Naruto's jutsus and Natsu's dragon slayer magic could combine in interesting ways during battles.
If they were brothers, they would probably have a very competitive relationship at first. Naruto is always trying to prove himself in the ninja world, and Natsu is constantly looking to be the strongest wizard. But over time, they would realize that together they are much stronger. Their different abilities would complement each other. For example, Naruto's wind - style jutsu could enhance Natsu's fire magic, making it even more powerful.
A possible plot could be that they are on a quest to find out the truth about their family. Along the way, they encounter various ninja clans who either help or hinder them. They might have to fight against those who don't want the truth to come out. Another plot could be that they are forced to team up against a powerful new enemy that threatens the entire ninja world. Their combined skills would be crucial in defeating this foe.
One possible storyline could be that they discover they are brothers through some long - lost family secret. Naruto, with his positive and energetic nature, could help Gaara open up more and overcome his past traumas even faster. They might team up to protect their new - found family bond against various threats in the ninja world.
One possible plot could be that Naruto, through some magical or time - traveling event, ends up in the world of Natsu. He then becomes an important figure in Natsu's family, eventually becoming his grandfather. He could pass on his ninja skills and values to Natsu, which would make Natsu a more powerful and wise mage.
In this fanfiction, it could start with Naruto feeling a strange connection to Natsu. As they meet, they discover their shared blood relation. Then, they embark on a journey to find out more about their family's past. Along the way, they encounter various challenges like facing off against enemies who are after their unique powers. They rely on each other's strengths, Naruto's strategic thinking and Natsu's brute force and magic, to survive and grow closer as brothers.
Maybe a plot twist could involve their family history. There could be a hidden enemy that targeted their family long ago, and now they have to face this threat together. As they dig deeper into their past, they find out secrets that change their view of themselves and their powers. It could also be that their brotherhood is a key to unlocking an ancient prophecy.
