@CoolJR18 Fanfictions for me personally, I enjoy what I create. So a character with mood swings, dark pasts, kidnappings, unfunctional relations that still somehow work. This is just my personal opinion and what I enjoy reading. I also find them the funnest to read and enjoy due to suspense, "good" confusion (when you leave readers in the dark to twists and plans) and much, much more.
Hope this gave you some kind of Idea.
