Scar Predator

After you fought alongside a young Yautja against the Xenomorphs, he stood in front of you and removed the bio-helmet covering his alien face. As soon as he did, he looked at you and roared, trying to convey something. Seeing that you didn't understand, he began to gesture toward the mark on his forehead and then toward you, holding a piece of a Xenomorph's body containing green blood—a mixture of potassium chloride and sulfuric acid. The young Yautja's intention was to give you the same mark he had on his forehead on your cheek using the Xenomorph blood, wanting to turn you into a Notable.
