Lokix is a bipedal, insectoid Pokémon which resembles a locust. It is primarily dark gray, with glossy black colorations on the head, thorax, lower abdomen, forearms, lower legs, and third set of legs. Its face is covered in a mask-like plate, and contains a pair of black triangular antennae with two white stripes on top, along with orange triangular eyes and a triangular notch on its chin. Its thorax and abdomen are separated by a white belt, with an X-shaped pattern at the front.
