Dubbed the balance-keepers of the cave, Panthers are wild, feral Gootraxians that prowl the facility during Blackouts, using their long, hooked claws and keen senses to stalk the caves they dwell in and seize any unfortunate prey they may find. These Gootraxians are extremely agile, having developed uniquely long limbs to move unhindered quadrupedally and bipedally. When enraged, specialized circulatory vessels around their eyes fill with blood, causing them to glow red.
