In most traditional Naruto and Blake storylines, Naruto has no relation to Blake as they belong to different fictional universes (Naruto and RWBY respectively). However, in some very creative fanfictions, an author might create a crossover scenario where Naruto could be made the father of Blake in a completely new and alternate storyline. But this is not a common or canon connection.
Friendship is also a big theme. They are both characters with their own sets of values and skills, and when they meet, the development of their friendship is a central focus. For example, they might start off as strangers and gradually come to trust and rely on each other.
If Blake were in the Naruto world, she might become a ninja with her own unique skills. Maybe she could use her shadow abilities in a way similar to some ninja techniques. For example, her shadow could be used to surprise opponents like a ninja's stealth attacks.
A very common theme is the idea of cross - universe interaction. Naruto is from the Naruto universe and Blake is from RWBY. Writers often play with how they would interact, communicate, and adapt to each other's worlds. Also, there's the theme of teamwork. How would they work together in a fight? That's often in these fanfictions. They might combine their powers in unexpected ways to defeat a powerful foe.
One possible story could be about Naruto finding himself in the world of Blake Belladonna. He might use his ninja skills to help Blake and her friends in their fight against the Grimm. Naruto's positive attitude and never - give - up spirit could inspire Blake to be more confident in her own abilities.
It could entail a journey where Naruto and Blake explore each other's worlds. Naruto could visit Blake's world and be amazed by the technology and the different creatures like the Faunus. Blake could then travel to Naruto's world and learn about ninjas and chakra. This exchange of cultures would be a major part of the fanfiction.
One common theme is friendship. Since both Naruto and Blake are characters who value their friends deeply, many fanfictions explore the development of their friendship when they interact. Another theme is the clash of different worlds. Naruto comes from a ninja - filled world and Blake from the RWBY universe, so there's often a focus on how their two very different worlds' elements interact and collide.
It's also possible that Blake is a character who is given a new backstory within the Naruto fanfic. They could be related to an existing Naruto clan in some way, or perhaps they are an outcast with a mysterious past that gradually unfolds as the story progresses.
One common theme is the clash of cultures. Naruto comes from a shinobi world and Blake from the RWBY universe, so there's a lot of exploration of how their different values and ways of life interact. Another theme is friendship. They often start as strangers and gradually become friends as they face challenges together.
Naruto's outgoing and determined personality would likely draw Blake out of her shell. She is often more reserved, but Naruto's enthusiasm could inspire her to be more open and take more risks. For example, Naruto would be eager to jump into a fight or a new adventure, and his energy might encourage Blake to be less hesitant.
