It would probably be full of interesting interactions. Naruto's energetic and determined nature would contrast with Erza's more serious and disciplined personality. There could be scenes where Naruto protects Erza or teaches her some of his ninja skills.
Yes, there are likely some fanfictions out there with such a concept. Fanfiction writers often come up with creative crossovers like this. However, the quality and nature of such fanfictions can vary greatly. Some might focus on how Naruto's ninja skills could influence Erza's world in Fairy Tail, while others could explore the family dynamic between them in an interesting way.
Yes, there might be such fanfics out there. You can try searching on popular fanfic websites like Fanfiction.net or Archive of Our Own (AO3). Just type in the relevant keywords like 'naruto erza brother fanfic' and see what comes up.
Well, in this fanfiction concept, it could work in terms of Naruto's protective nature. Naruto is known for his loyalty and his will to protect those he cares about. If he were Erza's older brother, he would surely use his skills and abilities to keep her safe. He could teach her some of his ninja techniques, which would be really cool to see combined with Erza's own combat skills. Also, Naruto's positive attitude could influence Erza in a different way, making her more open and perhaps less brooding at times.
One possible plot could be that Naruto, having grown up in a different world, suddenly discovers he has a sister in Erza's world. He travels to her world to protect her. Along the way, he has to learn about the magic in the Fairy Tail world while also teaching Erza some of his ninja skills. They could face a common enemy that threatens both their worlds, and their combined skills would be crucial in the fight.
It would be a relationship full of mutual growth. Naruto, with his never - give - up attitude, could inspire Erza to keep pushing forward in the face of adversity. At the same time, Erza's strong - willed and independent nature could make Naruto realize that he doesn't always have to carry the burden alone. They would also have a lot of fun together, with Naruto's sense of humor bringing some light - hearted moments into Erza's often - serious life.
They could have adventures where they combine their skills. Naruto could use his ninja techniques like shadow clones, and Erza could use her different armors and magic. For example, they might fight against a powerful enemy that is a threat to both their worlds. Naruto's clones could distract the enemy while Erza changes into her strongest armor to deliver a powerful blow.
I'm not sure if there is a specific fanfic with that exact premise. However, in the Naruto canon, Naruto has no such relation to Tsunade. Fanfic writers might create such a story for the sake of exploring different character dynamics and plot twists. They could potentially rewrite the backstories to make it work, like having Naruto be from a different family lineage that is related to Tsunade's in some way.
Yes, there might be such fanfictions out there. Fanfiction writers often create crossovers between different anime universes, and the idea of Naruto being Erza's brother is an interesting and unique concept that some might explore in their stories.
One common theme is the idea of family. Since Naruto and Erza are in a brother - sister relationship in these fanfics, the concept of building a new family, loyalty, and protecting each other is often explored.
