They could interact in a cultural exchange kind of way. Naruto could introduce the Avengers to the concept of ninja villages, the shinobi way of life, and the importance of honor in his world. The Avengers, on the other hand, could introduce Naruto to modern technology, different forms of government, and Western values. This interaction could lead to a deeper understanding between the two groups of characters and form the basis of a great fanfiction story.
They can interact through battles. For instance, Naruto might face off against Thor in a friendly spar. Naruto's speed and agility could be pitted against Thor's strength and lightning powers.
Naruto would interact in a very enthusiastic way. He'd be in awe of the Avengers' powers and would want to learn from them. At the same time, he'd show off his own ninja abilities. He might bond with Hulk over their shared 'rage' - like Naruto has his nine - tailed fox anger and Hulk has his own. He'd also try to cheer up the more serious Avengers like Black Widow with his positive attitude. And he'd probably try to get them all to do some ninja training together.
The characters would interact in interesting ways. Naruto, being the energetic and friendly ninja, would probably be excited to meet the Avengers. He'd be in awe of Iron Man's high - tech suit and might ask him a million questions about how it works. Thor, on the other hand, might be intrigued by Naruto's connection to nature through his chakra. Captain America would likely admire Naruto's never - give - up attitude. And Naruto would probably try to get Hulk to calm down when he's angry by using his own experiences of dealing with inner demons.
The Avengers could enlist the help of the NCIS when they need to solve a mystery on Earth that doesn't require superpowers but rather good detective work. For instance, if there is a conspiracy within a government agency that is related to a potential threat to the Avengers. The NCIS agents would use their skills to dig into the files and interview suspects. In return, the Avengers could protect the NCIS agents when they are in danger during the investigation. There could be some great banter between the two groups, like DiNozzo trying to make jokes with Clint Barton about their marksmanship skills.
In a fanfiction, the characters' personalities would greatly influence their interactions. Percy is a bit of a rebel and a free spirit, which could either clash or mesh well with the more structured Avengers. Thor, being a god - like figure in his own right, might recognize the power and divinity within Percy and the other demigods. They could share stories about their respective mythologies. Natasha Romanoff could take an interest in the demigods' combat training, which is different from her own. She might learn some new fighting techniques from them, while also teaching them some of her stealth and espionage skills.
Ladybug might be in awe of Captain America's leadership and sense of justice. She could learn a lot from him about leading a team. Meanwhile, Cat Noir would probably be intrigued by Iron Man's high - tech gadgets and try to get his hands on some. He might even joke around with Thor, comparing their 'cat - like' reflexes.
A possible plot could be that Naruto and some Avengers characters are brought together in a strange multiverse event. They form a team to fight a new common enemy that threatens both their worlds. Along the way, they learn about each other's powers and cultures, and Naruto's positive attitude starts to influence the Avengers in a good way, creating a strong bond among them.
I'm sorry, but 'lemon' often implies adult or inappropriate content in fanfiction, so I can't recommend such works. However, there are many great Naruto and Avengers crossover fanfictions without inappropriate elements that you can find on popular fanfiction websites like Fanfiction.net or Archive of Our Own by simply searching for 'Naruto Avengers crossover'.
Well, Naruto characters have unique abilities. For example, Naruto's shadow clones could be used for various strategies. Sasuke's Sharingan could detect hidden threats. They could join the Avengers to fight against Thanos. Maybe Naruto's Rasengan combined with Iron Man's repulsor technology could create a super - powerful attack.
The characters could interact through a shared mission. For instance, if there's a threat that endangers both the wizarding world and the world of the Avengers, they would have to work together. Harry could use his knowledge of magic to assist the Avengers in understanding the more mystical aspects of the threat, while the Avengers could use their combat skills and technology to fight the more physical parts of the enemy.
