If Neo were to join Team RWBY in fanfiction, it would be a huge change. Team RWBY is based on trust and friendship, and Neo has a history of being on the wrong side. But her unique fighting style could bring new strategies to the team. Maybe she could teach the others how to better deceive their opponents, like she does with her illusions. Also, her presence could create some internal conflicts as the team tries to figure out if they can really trust her.
It's popular because it combines two interesting elements. Neo is a really cool and mysterious character, and Team RWBY is already beloved. Putting them together creates new and exciting story possibilities.
There are fanfictions where Neo's joining Team RWBY is a result of a common enemy. In these stories, she uses her unique semblance to help the team in unexpected ways, like creating illusions to mislead the foes during battles.
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.
Neo's character could develop in several ways. She might start to open up more and become less of an enigma. Being around Team RWBY, who are all about friendship and loyalty, could make her question her past actions. For example, she could learn the value of teamwork and friendship, which she didn't really have before.
She could be a wildcard. Since Neo is quite unpredictable, her role might be to disrupt the normal order at Beacon. For example, she could start small rivalries between different teams just for fun.
He might have a bit of a culture shock at first. The world of RWBY is quite different from the Hidden Leaf Village. But his determination would fit right in with Team RWBY's own strong - willed members. He could teach them about chakra, and in return, learn about Dust. And his rasengan could be a very powerful weapon against the enemies in RWBY.
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.
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.
It could be a statement indicating that something related to RWBY's Neo is not fan - made fiction. Maybe it refers to official content about Neo that is distinct from fan - created stories.
