Jaune would likely become more self - reliant. Without the support of his friends and family, he'd have to learn to take care of himself. He might become more cautious in trusting others, having been betrayed by those closest to him.
His character could become more self - assured. Jedi are known for their confidence in their abilities, and Jaune might gain that as he masters Jedi - like powers.
One possible plot development could be Jaune's journey of self - discovery. He might start out feeling extremely down and lost after being abandoned. But then he could meet new characters who help him realize his own strength and worth outside of his former friends and family. For example, he could encounter a hermit - like figure who teaches him unique combat skills and gives him new perspectives on life.
In such a scenario, Jaune might become extremely depressed. He could lose confidence in himself and his abilities. Maybe he would start to question his purpose in the world of RWBY. This could lead to him either isolating himself further or trying desperately to prove his worth on his own.
In fanfiction, if Jaune was abandoned by his family, he might become more self - reliant. He could focus all his energy on his training at Beacon. Without the support of his family, he might form stronger bonds with his team members, seeing them as his new family. They would support him through his insecurities and he would grow to be a more independent fighter.
The story would change a great deal. Their expulsion would mean a loss of two important characters from the main group. This could lead to the remaining characters having to reevaluate their strategies. Without Jaune's growth and potential, the team might lack a certain kind of leadership or support. And without Blake, the team would lose her unique skills and perspective. It could also create a rift between the students and the school, with some blaming the school for being too harsh and others thinking it was a necessary decision.
Jaune might focus on self - improvement. He could train, study, and become stronger. By doing so, he would show his former friends that he doesn't need them to be great. He could also explore new parts of the RWBY world and meet new people who appreciate him for who he is.
He might cope by throwing himself into his studies and combat training. By focusing on becoming a better huntsman, he can distract himself from the pain of abandonment.
If Jaune is betrayed, RWBY's relationships with him could become stronger. They might feel more protective of him. Ruby would be more attentive, Weiss might be less cold towards him, Blake could offer more support, and Yang would be like a big sister to him.
Often, Jaune is portrayed as a somewhat clumsy but kind - hearted character at the start. In the harem - themed fanfictions, his kindness might be what attracts the various female characters to him. He could be shown as being a bit out of his depth when it comes to handling multiple romantic interests, but also growing and learning as the story progresses.
He could befriend a shy but brilliant student who helps him with his studies at the new school. This student might be an outcast like Jaune in some ways and they bond over their shared experiences.
