In a Haven - based RWBY fanfiction, Pyrrha's character could be developed by giving her a leadership role. She has the potential to be a great leader, but she might be hesitant at first. By taking on leadership at Haven, she would have to make tough decisions, deal with different personalities, and learn how to inspire others. This would not only test her abilities but also show different aspects of her character, like her wisdom, her ability to handle pressure, and her sense of justice.
A great way to develop Pyrrha further is through her relationships. At Haven, she could form new friendships or rivalries. If she befriends someone from a very different background, she might learn new values and ways of thinking. On the other hand, a rivalry could push her to constantly improve herself. Also, exploring her romantic side, if there are any potential love interests at Haven, could add more depth to her character. This could involve her learning about compromise and how to balance her feelings with her responsibilities as a Huntress - in - training.
By delving into her emotional side. Show her vulnerabilities, like her fears for her family's safety in the chaotic world of Remnant. This would make her more relatable.
The relationship can be developed through shared experiences. For example, if they are put in charge of a difficult mission together. They will have to communicate, trust each other, and rely on each other's skills. This will create a bond between them. Another way is if Pyrrha has some personal problems, like dealing with her fame as a champion. Glynda can offer her advice based on her own experiences. This will make Pyrrha see Glynda as a mentor and a friend.
In the RWBY Nebula X Ruby Fanfiction setting, Ruby's character can be developed further by facing her fears. For example, if there are strange and powerful creatures in the Nebula, Ruby has to overcome her initial fear of them to protect others. Also, she can develop her leadership skills more. If she is separated from her usual team and has to lead a group of new allies in the Nebula, she'll learn different leadership styles. Moreover, her relationship with Crescent Rose can be explored deeper. Maybe in the Nebula, she discovers new abilities of her weapon or has to repair it with limited resources, which would show her resourcefulness.
One possibility could be Pyrrha's secret training sessions at Haven. Maybe she discovers a new technique that she has to keep hidden from her teammates for some reason. This could add an element of mystery to the story.
Putting Wendy in a leadership role within the guild for a fanfiction story would be interesting. She could learn to be more assertive and make tough decisions, which would help her grow as a character. It would also show how she can inspire others in the guild.
Trixx could be developed by giving it more complex emotions. For example, it could feel guilt when its advice to its holder leads to a bad situation. This would add depth to its character.
To develop Android 17 further, you could explore his relationship with nature more. Since he has that love for animals, show him trying to protect a large area of wildlife from human destruction. This would not only show his growth in his beliefs but also his ability to take on big challenges.
His character can be developed by exploring his past. Maybe he has some unresolved issues from his early days as a ninja. For instance, he could have had a difficult relationship with his former sensei that still haunts him.
One way is to show his more vulnerable side. Maybe he's facing a threat that not even his power can easily overcome, and Percy has to help him in a way. This would make him more relatable.
One way to develop her character is to have her learn new skills. For instance, she could start training in martial arts or some form of magic that is accessible to humans in the Highschool DxD world. As she learns, she could face setbacks and challenges that force her to grow both as a fighter and as a person.
