Well, Naruto has always been very headstrong and determined as a boy. As a girl in this fanfiction, his character could develop in a way that combines his old tenacity with a new - found grace. He might learn to use his femininity as a strength, for example, in the art of deception during missions. His relationships with other characters would also shape his development differently. With his friends, he could learn to rely on them in new ways, and with his enemies, he might be underestimated even more, which could give him an advantage. All in all, his character development would be a fascinating journey of self - discovery and growth in the face of a major identity shift.
