Another theme could be adventure. They both come from worlds with a lot of action and danger. Fanfics might put them on a journey together, facing various foes and challenges. This could involve them using their unique abilities, like Raven's shape - shifting and Weiss's Glyphs, to overcome obstacles.
One common theme is friendship. Given their different personalities and backgrounds, exploring how they become friends or what kind of friendship they could have is popular. For example, Raven's more mysterious and rough nature contrasted with Weiss's more refined and sometimes uptight personality can create interesting friendship dynamics.
A third common theme might be self - discovery. Both characters have their own internal struggles. In fanfics, they could help each other grow and understand themselves better. Weiss might learn from Raven's more independent and survival - based mindset, while Raven could gain some refinement from Weiss. Also, in some fanfics, they might explore their own powers and how they can be used in new ways as part of their self - discovery journey.
Since I'm not overly familiar with 'raven branwen lemon fanfic' specifically, but generally in fanfics, common themes could include adventure, self - discovery, and relationships. In the case of a character - focused fanfic like this, it might explore Raven Branwen's past, her relationships with other characters in a more in - depth way, and how she grows or changes through different situations.
Power - sharing and teamwork are also common themes. They both have unique powers, and in these fanfictions, they usually end up working together. For example, Naruto's shadow clone jutsu combined with Raven's teleportation ability can create some really cool battle strategies. This exploration of how they share and combine their powers is quite popular.
One more theme could be the exploration of magic. Since Raven Branwen may have her own form of powers, in the fanfiction, she could compare and contrast her powers with the magic in the Harry Potter world. This could lead to some really cool plotlines where they try to learn from each other or even combine their powers to face a common threat. Also, themes of loyalty and betrayal might play out as new relationships are formed in this crossover of two very different fictional universes.
Well, family is often a big theme. Naruto growing up in a different family setting than in the original Naruto series. There could also be themes of loyalty. Does he stay loyal to his new family or his old friends? And then there's the theme of adaptation. He has to adapt to a whole new world with different rules and cultures. It's these kinds of themes that make the 'Naruto son of Raven Branwen' fanfiction so interesting to read.
Another option is Tumblr. There are many fans on Tumblr who create and share fanfics or at least talk about them. You can search for the relevant tags related to Raven Branwen and Weiss. However, Tumblr's search can be a bit tricky sometimes, so you may need to be patient and explore different combinations of tags.
Many fanfics also focus on the father of the child, if it's specified. It could be about how he reacts to the news and his role in Weiss's life during the pregnancy. Some fanfics might include themes of family support or lack thereof. For example, how Weiss's own family, with their complex history, responds to the situation.
The theme of identity is quite popular too. Raven has a split identity in a way, being both a bandit leader and having ties to the Huntsmen world. Fanfictions often play around with this, exploring how she reconciles these two parts of herself or how others view her because of her dual identity.
Redemption is also a theme. If Weiss made mistakes in the past or things didn't go as planned in her original timeline, time travel gives her a chance to make amends. She can try to right the wrongs and save the people she cares about. This adds a lot of emotional depth to the fanfics.

Maybe also something related to the relationship between the characters like Qrow and Branwen if they are from a certain story context.
