It's just weird for someone to have tha many types of powers. People's powers may come seemingly at random, but they all usually follow one them. Joto can shoot fireballs, Aqualad manipulates water and Terra [hesitation creeps into her voice] can move the earth. Saying "unfair" was kind of a joke. It's not a competition after all, when lives are stake. More like, someone like that would be too good to be true.
