Little is known about the appearance of Sotoraggians, as Sixsix is mutated and Sevenseven wears armor that completely covers his body. They normally refuse to take off their armor, for that is the source of their powers. Sotoraggians hunt assassin droids for right of passage and they can be fused with the techno-organic robots to gain more abilities. They are shown to be tough and very proud of their race, much like the Highbreed. Only mutated ones, like Sixsix, have gray skin with robotic eyes, but it's unknown what non-mutated Sotoraggians look like.
