The Xenomorphs are vicious predatory creatures with no higher goals than the propagation of their species and the destruction of any life that could pose a threat to them. Like wasps or bees, Xenomorphs are eusocial, with a fertile Queen breeding a host of subordinate castes. When standing upright, the Aliens are bipedal in form, though, depending on their host species, they will adopt either a hunched stance or remain fully erect when walking, sprinting, or in hotter environments. Their overall stance and general behavior seem to result from the mixture of the respective DNA of the embryo and its host. They have a skeletal, biomechanical appearance and are usually colored in muted shades of black, gray, blue or bronze. Their body heat matches the ambient temperature of the environment in which they are found, so they do not radiate heat, making them indistinguishable from their surroundings through thermal imaging. Aliens have segmented, blade-tipped tails. The sharp tip was initially a small, scorpion-like barb, but from Aliens onwards the blade design increased in size and changed in appearance to more closely resemble a slashing weapon. From Alien Resurrection onwards, the tails have a flat ridge of spines at the base of the blade. This was introduced to help them swim convincingly and was left intact in the subsequent crossovers. As a weapon, the strength of the tail is very effective, having been shown to be strong enough to impale and lift a Predator with seemingly little effort.
