This physical hurt then leads to her having to overcome not only the physical pain but also the mental and emotional challenges that come with it. For example, she might doubt her abilities after getting seriously injured in a fight. Also, themes of betrayal can be common, where she is hurt by someone she trusted, like a fellow student or a magical being, and has to navigate the feelings of hurt and distrust that follow.
A common theme is redemption. Since Sunset had a bit of a dark past in the MLP universe, many fanfictions focus on her journey to make up for her wrongdoings and become a better person, or pony in some cases.

For instance, the OC might be initially shy and through their adventures with Sunset Shimmer, they become more confident.
