18. Sabine Wren
Although she is from the Star Wars TV show that is mainly directed towards children, Star Wars Rebels, Sabine Wren has a TON of personality. She went to the Imperial Academy where she became a weapons developer. While still attending the academy, weapons she built for the empire were used on her own family. This made her very unhappy and depressed, like it would to anyone. That experience combined with other horror stories led her to leave the academy with Ketsu Onyo
Her and Ketsu Onyo started a partnership as bounty hunters after leaving the academy. The partnership didn’t last though and she eventually went on to become part of the Rebellion.
She was a graffiti artist, and the only character I can think of that has the trait of being a visual artist. That in and of itself would be a really cool development to explore in a character specific film.
