The Book of Sues and Stus

Sometimes, we come across those characters who are just too perfect. The ones who are overpowered, oversexualized, undermines the characters, and/or breaks canon. This is where I will review these characters. I'll criticizing these Mary Sues/Gary Stus, and at the end, I'll say where the creators can improve on them. (WARNING: Please do not harass the creators of these characters. No one deserves harassment.)
