In the fanfiction, the plot could revolve around Metal Sonic's transformation into a girl and her discovery of new emotions. Maybe she starts to feel empathy and kindness, which were not present in her robotic self before. This could lead her to question her loyalty to Dr. Eggman and eventually join Sonic's side.

A possible plot could be that the transformation of Metal Sonic into a girl is part of a bigger experiment by Dr. Eggman. He wants to see how this change will affect Metal Sonic's performance. As a girl, Metal Sonic could start to develop a sense of self - identity that is different from her previous programming. She might then rebel against Eggman's control, trying to find her own place in the world. Sonic and his friends could be initially skeptical of her but later accept her as an ally when they see her good intentions.
Sonic might be initially shocked and a bit confused. But being the hero he is, he would probably give her a chance to prove herself. Tails would be very curious and might try to figure out how the transformation happened scientifically. Knuckles would be more guarded, not trusting her right away.

Maybe Dr. Eggman would underestimate her in this new form, but she would prove him wrong by using her speed and skills in new and unexpected ways. She might also discover new aspects of her own personality that were hidden before the transformation.
Tails would probably be very curious and eager to figure out how to change Sonic back. He might study Sonic's new form scientifically.

Dr. Eggman would likely see this as an opportunity to take advantage of Sonic's confusion in her new form.
