The Crogs are an imperialistic hostile alien species.
They have no mouth or noses. They have fox-like ears with needles sticking out on their black skin heads, with no mouth but bright yellow eyes. They seem to be more bulky as they are strong and powerful enough to be in a war. They wear red armor as seen with Colonel Toros and General Kross.
They appear as a conqueror race that breaks the will of weaker species and lives in utter and chaotic war over time. They often take over planets and force alliances with races to secure their conquest for power like for example Aikka's people.
