Xenomorphs are silicon-based life forms instead of humans carbon based life forms.It is also rumored that their name (Xenomorph)is also stands what they turn into like Xeno which stands for strange or alien and morph which is to change into another shape or form.So Xenomorph stands for strange shape or form.

More info on xenomorphsEdit

Reference should be made to the Alien section in the Colonial Marines Technical Manual. From there, the editor for this article should be able to extract some information on the xenomorph's biology. - 16:54, 8 March 2009 (UTC)

Yes, exactly. I remember reading that they described as "fluorine-based lifeforms" with a lot implications for their internal biology, namely their acidic blood. 18:11, February 14, 2011 (UTC)


its head doesnt look like a elongated human scale it actually looks kinda like a how phrase this erect male genetalia

Xenomorph CastesEdit

One thing that seems to be a problem is the use of the term caste in reference to variants caused by differences in the host species. For instance, a Predalien has existed in the expanded cannon as a drone, warrior, and queen. In such a case, predalien refers to a variant xenomorph based upon the host. The Castes themselves are drone, warrior, and queen. I propose that the current "castes" (as of 28 january 2010) be divided into castes and variants. Malys88 00:07, January 29, 2010 (UTC)

Can you help me?Edit

Do you know anyone (i'm pretty sure you do) that knows the Aliens Series (Xenomorphs) that can help me edit the page I created on the Metroid Wikia

Here is the Article (Metroid101 02:31, jary 1 2011 (UTC)) I do am good love them i am willing to served them as long as they don't kill people any more then i will obay their comman. Xenomorph i have somthing to tell you i will served you if do not hart me or anything alse i will be glad to help you. the that need help give xenomorph this paper please let me know what he says.

love, Andrew T.

Home Planet Edit

In the the end of Alien vs Predator 2010, its said they have a homeworld, has that been in the page yet? -General Q-Nek hey, its me again xenomoph i will served you if you will not harm me or anyone alse out thier then iam yours for the taking but if your not alien or the xenomoph that you are then who are you. please show me a picutre of if only are alien or a xenomoph. thank you sign andrew T.

I have not seen anything on this page regarding the homeworld. In the first Aliens omnibus published by DarkHorse, a human operation was sent out to what was believed to be the Xenomorphs' homeworld, however, based upon another one of the stories in the omnibus, that may have been the homeworld in the context of it being their queen mother/ empress's homeworld. Who said it in the game and what evidence was provided for it in the game? Malys88 13:41, April 7, 2010 (UTC)


In the ending of AVP 2010, All xenomorphs are reffered to as female, In the predator campaign, when faceing the Praetorian, the advisor says "She is stronger than her sisters", It is also seen that in the end cinimatic, that specimen 6 could not have been with a mate, as she was taken on her own, but molts into a queen for reproduction, This can mean two things:

  • Xenomorph queens ARE asexual, In the first AVP movie, No drones are alive while the queen produces eggs
  • Xenomorph queens Are NOT asexual, but rather mate with the first potential host in their hive, leading to something very intresting of a reproduction cycle, seeing that it requires an entirely diffrent species to reproduce 12:57, April 17, 2010 (UTC)S'Arais

I am of the opinion that the Xenomorph species does not fall under normal categories of reproduction. There is no evidence of any sexual dimorphism in any of the works of fiction, and the only variants that referred to in the masculine form are experimental variants created by human scientists. However, the feminine form is used to describe non-reproductive castes in ants, so that might be a convention used by the scientists in the series in reference to the drones/warriors. The logic behind the naming of the queen is straightforward, as it is the unique individual in a hive which is solely responsible for reproducing. In as so far as the issue of mating is concerned, it seems that the xenomorphs clearly need hosts of other species and do not procreate among themselves, therefore it follows to reasont that the xenomorphs acguire some of the DNA of their hosts to maintain genetic diversity. One might consider the xenomorphs as "xenosexual".Malys88 23:13, April 17, 2010 (UTC)

I mean, The queen would require another species' male (Like human or Yautja) to acctualy begin to lay the eggs in the first place, let alone for facehuggers to latch onto a host 04:21, April 18, 2010 (UTC)S'Arais

While I consider them a sexual being - you have forgot a type of reproduction: parthenogenesis (they could also be born pregnant, like Tribbles). But do not forget that they were presumably created by the Space Jockeys and are described as biomechanical in nature - there could be a mechanical procedure in them that allows asexual reproduction (as I believe they meant 'biomechanical' as a sort of alternate phrasing for 'natural cyborg'). If it were not for the Kenner Toys which I grew up on, and knowing how inhuman the Xenomorphs are, I would assume some form of asexual or nonsexual reproductive formation. -- Somarinoa 22:45, June 20, 2011 (UTC)

Lol, 2010. Talking to a brick wall here Somar. :P Anyway, don't know if you know already, but I've nominated Holbenilord for ensign rights. Much appreciated for him if you would vote and/or give comment. Insurgence: Like the Phoenix I rise again! 23:04, June 20, 2011 (UTC)

I'll look into it after a successful restart. -- Somarinoa 07:15, June 22, 2011 (UTC)

leprosy Edit

in several alien comics, it is shown that leprosy will prevent a chestburster from emerging! should this info be included here? ralok 20:34, May 4, 2012 (UTC)

cleanup Edit

this page needs a significant cleanup, there seems to be serious errors on the page causing misplacement of things . . . ralok 21:29, June 13, 2012 (UTC)

Genetics Edit

there is a slight problem with the latching onto an aertery for dna, blood contains no dna in humans, or that is, red blood cells and platelets dont. However the rest of the body tissue around the egg is rife with it. 09:38, October 15, 2014 (UTC)


Do they ever impale victims with their tails in the Alien series? I'm not sure coz I haven't seen those movies in a while but I only seem to remember them doing it in Alien vs. Predator, which is part of the Predator series. I also checked deathlists and all on-screen kills seem to be either tongue or chestburster. Is the tail stab exclusive to AVP and AVPR or do they do it in the Alien movies too? If the former, I think that should be noted but again I'm not 100% sure. Ghostkaiba297 (talk) 03:06, February 12, 2015 (UTC)

The Queen does it in "Aliens". Because of the greatness her majesty possesses the tail has enough momentum to penetrate a human body easily. That special technique is probably used by her drones too but it wasn't shown in the movies. I also cannot remember seeing the blade at the tip of the tails in Alien 1-3.

"Alien: Isolations" Xenomorph howsoever makes use of its tail quite frequently. It is maybe a new feature ported over to the old concept but it makes sense. The tail has a job to do instead of just "hanging around". It works well together with the whole xenomorph concept and is a change that doesn't disgust the purist in me. 17:38, August 20, 2016 (UTC)

I think they should make a movie about the Deacon
