One idea could be Neo using her unique abilities in unexpected ways to help the team in a new adventure. Maybe she discovers a new form of her Semblance that gives her an edge in combat.
One common theme is self - discovery. Neo often has to figure out more about herself in these stories. Another theme is power struggles. Since Neo has her own set of powers, there are often situations where she is in a power struggle with other characters or forces.
A 'rwby neo brainwashed fanfic' might explore the concept of Neo being brainwashed, which could lead to a lot of interesting character developments. For example, it could change her relationships with other characters in the RWBY universe. Her actions and decisions would no longer be solely based on her own will, but rather on the influence of the brainwashing. This could create a whole new set of storylines and conflicts.
Well, there's 'Neo's Hidden Powers' in RWBY Futa Neo fanfiction. In this story, Neo discovers some unexpected powers she has and how she uses them to face different challenges. Also, 'Neo and the Lost Artifact' is quite engaging as it involves Neo on a quest for a powerful and mysterious artifact.
One possible development is that Neo becomes more protective. As she's going to be a mother, she might become more aggressive in defending herself and her unborn baby from any threats in the RWBY world. This could also lead to her making new alliances or breaking old ones depending on who she perceives as a threat or an ally. Another aspect could be her internal struggle with her new identity as a soon - to - be mother, which could change her personality over time.
One common theme is identity. Since Neo has a rather mysterious past, many fanfics explore who she really is. Another is revenge. Given her actions in the RWBY series, some fanfics have her seeking revenge or others seeking revenge on her.
Roman Torchwick could be a likely candidate in some fanfics. Since he had a connection with Neo in the original series, he might be brought back in a fanfic to brainwash her for his own ends. Another one could be Salem. She's always looking for ways to gain an edge, and Neo's skills would be useful to her if she could control her.
The reincarnated character is a main character too. Their actions and decisions drive the story. They have to navigate Neo's life and relationships. And then there are likely antagonists. It could be Salem's minions or other villains from the RWBY series who will be in conflict with the reincarnated Neo and the other characters.
One common theme could be mind control. Since hypnosis is involved, the idea of Neo controlling someone's mind or having her mind controlled in some way might be present. Another theme could be the exploration of Neo's character in a more in - depth way, perhaps showing her motives or backstory related to the hypnosis aspect.
