Yautja blood is a neon green bioluminescent substance that originates from a Yautja's body. The substance is known to be a life giving substance, which gives virtually any known species an extended lifespan. This was first discovered by Hunter Borgia, who utilized the blood in order to keep himself alive after a century. However, it needs to be constantly used in order for him to remain alive. Another aspect of the blood is that it can be somewhat chunky and mostly liquid at the time. Yautja blood is also known to possess the ability to neutralize Xenomorph XX121's corrosive blood.
