One main theme is adaptation. Raven has to adapt to the Naruto world which is very different from her own. Another is identity, as her transformation often makes her question who she is in this new context. And there's also the theme of power, as her new form may bring new powers or change the way she uses her existing ones.
One popular Naruto Raven TF fanfiction is 'The Transformation of Raven in the Naruto World'. It has an interesting plot where Raven somehow gets transported to the Naruto universe and undergoes a series of changes. Another one could be 'Raven's New Identity in Naruto'. These fanfictions often explore how Raven's character adapts to the new and different environment of Naruto.
In a fanfiction, their relationship could also be explored in terms of leadership. Naruto has led his team in many battles and has a sense of responsibility towards his comrades. Raven has her own group and her own way of leading. They could compare and contrast their leadership styles. Maybe they would have some disagreements at first, but as they get to know each other better, they could find a middle ground and lead a combined force against a greater threat in the RWBY universe.
Naruto has his chakra - based powers like the Rasengan. Raven has his telekinetic and shadow powers. They could combine Naruto's Rasengan with Raven's telekinesis to create a super - powered attack, where Raven uses his power to guide and enhance the speed and force of Naruto's Rasengan.
There's no way for me to tell who the author of the 'Naruto Father of Raven Fanfiction' is. It could be someone from a small fanfiction community or a new writer. You might need to search on specific fanfiction platforms and look through the details of the story to find out the author.
I'm not entirely sure specifically as there could be many different takes in a fanfiction with such a title. It might be a story where Naruto somehow becomes the father figure to a character named Raven, perhaps in an alternate universe where their paths cross in unexpected ways.
If Naruto met Raven in a RWBY fanfiction, it would be an interesting dynamic. Naruto might be initially confused by the different world he's in. Raven, being the cautious type, would likely be on guard around this strange new person. Naruto's bright and energetic personality could start to break down Raven's walls over time. He could show her that there are different ways to approach life and battle than she's used to.
Well, in the realm of fanfiction, all kinds of wild ideas are possible. It's not unheard of for someone to write a story where Naruto is Raven's father. This kind of cross - over fanfiction often combines the elements of the Naruto universe and Raven's universe in interesting ways. Maybe the author was inspired by the similarities in the characters' powers or personalities in their respective shows and decided to create this unique family connection in a fan - made story.
A common theme is the clash of cultures. Since Raven comes from a different context and Naruto has its own unique ninja culture, stories often explore how they deal with these differences.
Yes, it can be quite popular among fans who enjoy crossovers and shipping different characters. People like to explore the dynamic between Naruto's energetic and determined nature and Raven's more mysterious and brooding personality in a romantic context.
