The two most prominentXenomorph - stamp out coinage in theAlienUniverse are seemingly humans and Predators , but as it turns out , neither of them can even start out to qualify for the rubric of their ‘ greatest scourge ’ , as that honor goes to something that is drive to eliminate the Xenomorphs ’ entire species – and has the means to do so .

The first Xenomorph fan ever sawwas insert in 1979’sAlien , and it was pour down by the ending of the same picture . In the sequel , Aliens , buff are present an intact hive of Xenomorphs , arrant with a fagot and a hierarchy of roles and place specify to each Xenomorph in the hive . This small civilisation of Xenomorphs was wholly destroyed by the end ofAliens , and only a few Facehuggers live into the third movie . Those survivor gave life to two of the last - known Xenomorphs in the universe – and they were also killed . This drift confirms that humans ( specifically Ellen Ripley ) are very good at killing Xenomorphs , though arguably not as good as Predators . Predators hunting Xenomorphs as part of their Blooding Ritual , which is a rite of handing over a Yautja must go through to become a mature fellow member of their clan . In fact , marauder seed entire planets with Xenomorph lifeto ensure their hunt can continue forever , as Xenomorphs are that of import to their polish . Both of these illustration prove how in effect humans and Predators are at killing Xenomorphs , but even so , they are nothing compared to their genuine greatest scourge : the Red Xenomorph .

Red Xenomorphs are Xenomorphs’ Evolutionary Successor, & Seek Only Genocide

In the four - part miniseriesAliens : Genocideby Mike Richardson , John Arcudi , and Damon Willis , readers are introduce to a major planet know as Xenomorph Prime , the homeworld of the iconic alien creatures . After the first Queen Mother of Xenomorph Prime was stolen from the planet , the metal money underwent an evolutionary change with the birth of the Queen Mother ’s replacement : the first Red Xenomorph . The Red Queen give life-time to a drove of Red Xenomorphs , and they rapidly channelize to overtake the planet from what remained of the original Xenomorphs . However , the original were able-bodied to recuperate without undergoing variation , and a novel Queen Mother take the place of the first . This meant that there were two Queen mother on Xenomorph Prime , one of the original Xenomorph species , and one that ushered in the new geological era of the red version . Both Queen Mothers call out to their child , and ordered them to do one thing : eradicate the other .

This serial publication confirm that the Xenomorphs ’ natural predators are the Red Xenomorphs , as they are bear with the exclusive - given finish of replacing the original strain , which makes them right smart more of a menace to Xenomorphs than humans or Predators . first , humans can only really handle a modest legion of Xenomorphs at most , and that ’s only with nuclear capability , so the idea that human beings are a serious threat to the Xenomorph species as a whole is a jest . As far as Predators go , they are actually responsible for for the security and expansion of the Xenomorph species across the existence . Sure , they kill them regularly as part of their ritualistic hunt , but predatory animal have arguably facilitate the Xenomorphs path more than they ’ve hurt them .

After break down these relationships , and looking at the real menace - tier each of these species / subspecies model , the Red Xenomorphs are an wanton option when naming the Xenomorphs greatest threat inAlien , as their entire existence revolve around killingXenomorphs , and they have the means to do so .
