My least favorite character from Fairy Tail is this guy. The former Sabertooth guild master, Jiemma. He is a total a*s. Considering the fact that he raised poor Minerva in such a way that she literally was pure evil, that he stripped Yukino of her pride that she no longer wanted to be a celestial mage anymore, and when he broke Sting by making Lector disappear. Yup... hate this guy.
