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.
In fanfics, Neo is often depicted as highly skilled. Her illusions and combat abilities are usually emphasized. She's also shown as quite mysterious, which makes her an interesting character to explore.
A fanfiction about Neo RWBY injured could explore the emotional side. For example, when Neo is injured, she might have flashbacks of her past. Maybe she was once betrayed and being injured now makes her feel vulnerable again. This could change her perspective on her actions against RWBY.
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.
Ruby could potentially be Neo's friend. Ruby is friendly and open - minded. In a swimsuit fanfiction, they could bond over their shared love for adventure. Maybe they go on a treasure hunt on the beach together.
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.
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.
I'm not entirely sure specifically as it could refer to a lot of things. It might be a fanfiction where Neo from RWBY is in an attacked or attacking situation. Maybe it's about Neo facing off against some foes in a fan - created story within the RWBY universe.
Neo could bring a new dynamic to Beacon. She might be initially shunned because of her association with the criminal underworld. But as time goes on, her unique skills in combat and deception could prove useful in battles against Grimm, and she could earn the respect of her peers.
