Pteranax is a massive bird-reptile like humanoid of some sort. Like Cheirus he is ten times the size of his own species and ruled an entire planet. He was greyish blue in colour with leopard like spots and red eyes. He speaks in a dark, deep and almost clear accent. He is not much smarter than Cheirus even though they necessarily have things in common like a heavily built mothership than can go into deep space, horrible at architecture and rather massive mech suits that are unimaginably huge and can crush 30 Argentinosauruses with one foot.
