I'm doing this one in support of my facehugger life span thread and my chestburster removal thread.It seemed all facehugger removals result in death,whether it's the acid,or they pull of the victims face,it doesn't seem possible.But could it be done?What if the facehugger was exposed to radiation?Is there a way to remove the facehugger before it can implant the embryo?

I thought there were two in the canisters in Aliens? If memory serves, one was removed but the host died in the process. I cannot account for the other.

A very basic way might to aim the specimen toward a specific area (extremely basis to best counter act the acid). Make a slit and let it bleed out until it dies.

They were partially successful in the River of Pain novel by freezing the joints with liquid nitrogen, and breaking off the affected leg, but they also killed the flesh on the hosts cheek. The hugger reacted by starting to strangle the host then the frozen joints warmed up and started to bleed acid on the hosts face.

Other old comics have shown huggers being ripped or shot off, with any potential side effects from acid or strangulation handwaved, so they come off a bit farfetched.

I think any radiation strong enough to harm an organism with polarised silicon for skin would do more harm to the host.

Any cuts heal too quickly.

There were six in stasis tubes in Aliens.  Two were alive and four dead.

Those are somethings i hadn't considered.Thanks guys.How about putting them on ice?

Thank you. I am unfamiliar with texts you reference.

I propose we FIND A WAY! Could you start- maybe on a new thread and we can see where the idea goes?


XenomorphMember1234 XPFeb-06-2017 10:05 PM

Anything you do to the hugger is either going to directly harm the host, or cause the hugger to harm the host.  Maybe you could give it a blood transfusion to dial up the pH of the acid, but it would probably strangle the host in the meantime.


TrilobiteMember8212 XPFeb-06-2017 10:12 PM

SM. Perhaps the crew has a blood supply refrigerated and they could task a synth to somehow test it with on board chemicals to match ph/blood type?


PraetorianMember3073 XPFeb-06-2017 10:15 PM

Great suggestions guys!

Still have the problem of it choking the host as soon as you touch it.


TrilobiteMember8212 XPFeb-06-2017 10:33 PM

Emergency chrich- IF the tail could be unwound for access?


OvomorphMember27 XPFeb-07-2017 4:35 AM

The only way you could do it is to make it think the host is dead. You put the host in clinical death, electrical or chemical induced state causing heart failure. The trick is you must do it fast, before the facehugger impregnates the host.

If the facehugger releases the host you catch the freaking thing, and do reanimation of the host. 


DeaconMember10358 XPFeb-07-2017 5:33 AM

I covered this a bit in the other Topic.

It would seem that the Face Hugger has to stay on the face after implanting the Embryo for a PURPOSE.

This is likely if we consider the Organisms sole purpose is procreation and its task is to make sure successful procreation has occurred then the Face Hugger would not naturally release itself off the Face until the Embryo has grown to a specific stage of development.

So for a successful Parasite to operate it would have some functions that would insure it can carry out that task and so having it pose a threat to the Host if any attempt to remove it would certainly be logical on its part.

So this brings us to the point of Defense Mechanisms that would help to prevent the Face Hugger from being removed until its task is completed, and these Defense Mechanisms could most likely include.

*Constricting its tail to cut off air supply to the Host

*Latching on to the face so hard that the only way to remove would be to cut if off which leads to Acid on the Hosts head.

But then maybe it could also.

*Inflate and detach its implantation tube so this blocks the Hosts Airway.

*Release Acid or Toxics into the Host to kill them.

So it would make removal of the Face Hugger a extremely risky and daunting task.

But eventually if would release itself, when the Embryo is at a certain stage. It would be logical that at this stage the Embryo has grown to a size that it is near birthing and can now defend itself to some degree.

so it would be Logical if the Chest Buster after the Face Hugger as released itself has some Defense Mechanisms

*Maybe at this Embryo Stage its attached to the Rib-cage or it can latch onto it.  Making this a difficult operation to remove it surgically. Until its very close to the stage where it would be ready to Chest Burst.

*Maybe it can secret Acid as a Defense Mechanisms maybe it can do this on the Rib-cage wall, secret a slime that has some properties of the Acid so as to weaken the Rib-cage which may cause the Host a feeling of strong heart burn? If the Organism can do this, then maybe it can release this as a Defense Mechanism?

*When the Organism is at a certain growth, after the Face Hugger releases itself, maybe the Organism inside can now move about if its disturbed which would make removing it difficult without the Organisms movements causing Trauma to the Hosts Organs and making extraction difficult with the risk of wounding the Organism (Acid Blood) or damage to internal Organs from the Apparatus/Method of trying to catch say a Frog in a Bucket with Oil all over your hands.

However Movies in the Franchise have shown a Successful removal had occurred and the Host had recovered.

So i think there would likely have to be a Peach Spot between when the Face Hugger Drops off and prior to Chest Busting when they can remove the Organism and it would be logically if some kind of Sedation Method was used to incapacitate to a degree the Xenomorph Fetus.

Considering that the face-hugger has highly (pressurized) acidic blood, I think a viable course of action would be to introduce a base (calcium hydroxide, sodium choride, etc.) into its blood stream to neutralize the acidity. Most likely, some serious experimentation would have to be done to ensure that the base isn't too strong, as the resultant interaction with the acid could cause just as much or even more damage than the acid itself. Similarly, the base probably would have to be stronger than everyday "arm & hammer" baking soda for it to effectively work. It is at this point , removal would be feasible without significant damage to the host.


XenomorphMember1261 XPFeb-07-2017 6:20 AM

If you recall in AR the queen fetus had an umbilical cord attached.  So sedating the fetus and the host at the same time is definitely a possibility. 


NeomorphMember1823 XPFeb-07-2017 8:36 AM

I think it is a very difficult one. in alien as soon as they touched the hugger its tail tightened around kanes throat. it can obviously sense danger and im sure it has more ways that strangulation to kill the host. just like the concentrated acid for blood, everything about the hugger is designed so it cannot be removed before implantation without killing the host. interestingly, I recently saw a theory on the acidic blood working in the same concept at the acid in a car battery, being a form of power source for the aliens and its defensive quality being a convenient secondary purpose


FacehuggerMember355 XPFeb-07-2017 8:44 AM


See my post ref the alien acid above. I believe it would be the most scientifically-proven way of neutralizing the face-huggers highly corrosive acid (And probably killing it in the process) so you can physically remove it.


FacehuggerMember355 XPFeb-07-2017 8:49 AM

Just a note to add that a base could easily be injected into the face-hugger with a corrosive resistant needle (many types of modern thermo-dynamic materials such as pecora mastic and PTFE are resistant to the effects of acid.)


NeomorphMember1823 XPFeb-07-2017 8:51 AM

yes u can kill it, but it has shown awareness by tightening its grip on the hosts throat. theres nothing to suggest it wouldn't have time to feed a deadly toxin down into the host before it dies


NeomorphMember1823 XPFeb-07-2017 8:56 AM

it may also have completely parelised the hosts respiratory system and is breathing for it, much like a ventilator does. killing it may kill the host as the host may be unable to breath as theyr lungs don't function. perhaps the huggers last act, upon completion on implantation, is to allow the hosts respiratory system to start functioning again on its own


FacehuggerMember355 XPFeb-07-2017 9:13 AM


Its an interesting point. I am not sure if anybody really knows all the capabilities that the face-hugger brings to bear. I will say that the acid-base reaction in the blood stream would be nearly instantaneous so the tail tightening its wrap around the neck to choke the victim is not probably an issue to consider.

However, I am not sure if the face-hugger has toxins (or a delivery system for that toxin) it can emplace into the victim once it realizes it's time has been cut short.  It's delivery methods for a hypothetical toxin may take only a few seconds which would be about all it has after the base is injected into it.

In practicality, most physical defense mechanisms would be rendered ineffective by the thermogenic acid-base reaction (With the exception of immediately detaching its insertion tube, which may choke the victim to death). Latent defense methods i.e. such as the spore becoming posionous or even cancerous if it is not properly "nourished" by the face-hugger, are another story altogether.

Can anyone out there in the Alien universe elaborate further on the defense methods? Really want to get after them from a scientific point of view.  It's an impressive organism, no doubt, but nothing is flawless.


XenomorphMember1234 XPFeb-07-2017 11:35 AM

It tried to strangle Kane and tear his flesh when Ash so much as touched it's leg, and it secreted acid to get through his helmet.

How do you get around these defences even if you can stop the acid blood dissolving the needle you use to inject the base?


FacehuggerMember355 XPFeb-07-2017 1:11 PM


I stated earlier that a nuetralizing base could easily be injected into the face-hugger with a corrosive resistant needle  or dart. (many types of modern thermo-dynamic materials such as pecora mastic and PTFE are totally resistant to the effects of highly corrosive acids such as Sulphuric or Hydrocholric acid.)

Looking at the different Aliens movies, it ascertains that the face-huggers detect human presence at a certain distance (10 feet give or take..?) and release themselves from the eggs at that point. An individual can stand 50 feet away (or more if required),  fire a dart with the base agent into it and almost instantaneously, the acid is neutralized and the thermogenic increase in metal salts and water within its blood stream should kill the face-hugger...



ChestbursterMember739 XPFeb-07-2017 1:26 PM

Radiation could work but it's a risky move as it could also severely damage or even kill the host. 


XenomorphMember1234 XPFeb-07-2017 1:32 PM

The dart isn't a bad idea.

Assuming you have a plastic that won't dissolve in seconds (Alien acid eats through plastics just as well as metal).

And assuming you can fit enough base in the dart.

And assuming it doesn't kill the host while the base takes affect.


NeomorphMember1656 XPFeb-11-2017 12:13 PM

Getting rid of the facehugger is one thing but you must also stop it from laying the egg inside the human. I am not sure how long time it would take for it to lay an egg. Perhaps you could freeze the human and take out the egg later but I am not sure to take care of the monster.


PraetorianMember3073 XPFeb-11-2017 1:18 PM

That's the main reason I posted this forum.There isn't much of a point in removing it if you can't stop the embryo from being laid.

Nothing the God of biomechanics wouldn't let you in heaven for 


OvomorphMember11 XPMay-26-2017 8:53 PM

I hope this thread is still relevant now, although I am late to the party. Removing the facehugger is definitely one thing, but as observed in most of the franchise's games and movies by now, the embryo will still be laid regardless of the situation.

I know radiation is risky, but maybe if a chestburster was captured and experimented on with different types of radiation, perhaps the right one can be optimized to kill the baby from within. This kind of reminds me of how a radiation machine was used to kill a mind controlling parasite in Resident Evil 4 here:

Exhibit A

What about electricity? Sure, the host may become unconscious after a certain voltage is applied for a certain duration of time, but they are still able to recover from that damage given time to recover. Meanwhile, the premature chestburster in the host is more vulnerable to the effects of the shockwave, and if it doesn't die at first, it can still be safely surgically removed from the host to be disposed of in that way. I guess my thought process is kinda crazy, but I am kind of leaning more hope towards using the electric chair anyways.



TrilobiteMember8212 XPMay-26-2017 9:07 PM

Well, I haven't seen AC yet but I saw a trailer where a character just pull a hugger off lickety split lol!


PraetorianMember2861 XPMay-26-2017 10:14 PM

The 'acid' involved, isn't acid. I checked with hubby some months ago, and we dug up the clip from the facehugger bleed, and figured out approx amount and speed of effect.

There's NO way a corrosive can act that fast vs alloys. Period, as it violates some thermodynamic principles.

HOWEVER, if it's an Oxygen-reactive substance that specifically attacks covalent and ionic bonds, THEN you have the same effects as seen on-screen...and in my story. ;)
Such a liquid would eat through literally anything, including teflon with equal ability and would only cease when it's ocidation-limit was reached.

This also explains why it doesn't consume the creatures from the inside, as it would need a second or two depending on temperature to activate, thus allowing bleeds to heal.

However, supercooling such a substance doesn't work as it's endothermic on a cascade tiny reaction point and it starts heating up, thus driving it's own action via it's own heat.

Thus, not an acid, but a molecular-disassembler really, in liquid form. Base elements wouldn't work any better vs it than would teflon, glass, steel, etc..

Facehugger removal?
Track the progress of implantation via MRI and when it's close, open the patient surgically, and 'catch' the egg capsule as it arrives, then let the facehugger detach and die normally thinking it's done it's job.

As a way of getting around it strangling the host?
Heart-Lung machine as used for surgery these days. ;)
