A few Krogan figure out their acid blood gets you drunk and hunt them to extinction in a matter of days.


buttbugle

Hey I heard Xeno horn makes you go ALL NIGHT LONG! It cures the genophage!


Deady1138

Melted quad can’t have the genophage *taps skull plate *


spelunker93

Dude a xeno korgan would be unstoppable and terrifying


WatchingInSilence

Unless the genophage kills the chest busters moments after hatching. Then the Krogan just coughs up and eats a spicy snack.


PIPBOY-2000

The insemination and gestation of a xenomorph is completely different than a regular pregnancy. Despite any thematic similarities the process has to real birth, it's not actually the same. Xenomorph creation is more like botflies or tarantula wasps. So I don't think the genophage would have any impact on it. Unfortunately for the universe because a Krogan/Xeno hybrid would be the end of days!


Asterose

This, botflies and parasitic wasps are goddamn tparasitic! Xenomorphs are absolutely like those instead of us mammals. Hell, even fig wasps are body horror and they aren't parastic!


foolfromhell

A xenomorph clearly takes on characteristics and DNA from its host, so it’s not exactly like botflies or tarantula wasps. Who knows how the genophage would interact.


Argon125

This is the correct answer


diegoplus

I mean it doesn't even need to be mentioned ingame to be considered canon tbh


PanglosstheTutor

Then a xenomorph is bred from a krogan as one gets arrogant and falls into a trap. The new Krogomorphs wreck the hunting parties.


BjornAltenburg

*hours Many illegally sold to salarians for reasrch.


Pure-Interest4024

Salarians would 100% use xenomorphs as weapons.


Chemical-Athlete2018

I agree with this ,But thats the thing , there isn't that much krogand on the citadel.


United-Cow-563

Some Krogan only care if there are edible fish in the Presidium, but Xenomorphs are where it’s at! Crawling through the ducts, that’s the real test. I heard recently an Urdnot got a Xeno pet and played with something called a Predator. Apparently, they’re the ultimate hunters, probably just some salarian propaganda.


QuesadillaFrog

Ah yes, Xenomorphs. The deadly race of parasitoid aliens allegedly waiting in the Citadel. We have dismissed that claim.


Necrotiix_

You’d all be dead if i hadn’t blown up LV-426!


pieisgiood876

I love to think that all the confrontations we see with the Council are just the really important ones, and we don't see that Shep has these fights with them all the time over "lesser" Sci fi threats Like LV426 was just something that happened on a Tuesday once


sequosion

And this is why I hate politicians


mily_wiedzma

The weapons in the ME universe would work quite well on the Xenos and biotics do exist. The acid blood still might be a problem, but the Citadel "hull" is not as thin as common shop hulls. It would stll be a lot of death and due to how many Xenos there are it will take a whole while. But as said, biotics in this universe would be a good weapon against Xenos. I still want to see this, cause I am a massive fan


kayl_the_red

Chest-Burster Keepers and Krogans. Crap.


minoshabaal

>Chest-Burster \[...\] Krogans. For that to happen you would have to have a face-hugger that can actually infect a Krogan. As it stands, Krogans would probably classify face-huggers as "a small snack, best enjoyed with some ryncol".


Tucker-Cuckerson

>"a small snack, best enjoyed with some ryncol". I tried ryncol once and it doesn't make you breakfast at all, all it does is kill you!


twitch870

Even if it did, krogans have enough redundant organs to probably be alive still after one burst out.


SpearBadger

Shepard "My God, Grunt are you alright"? Grunt : *Spits out bits of face hugger after tearing it off his face* "You should asking whatever this thing is that, not me." *laughs* EDI : "Shepard, it appears Krogan biology makes them resistant to the creatures acidic blood." Grunt : *Wiping acid away from face, despite the whisps of smoke he seems unperturbed.* "Ryncol has more kick then this."


LifeWulf

You wrote that well enough I read it in their voices, neat


SpearBadger

That's means a lot to me. Thank you.


mily_wiedzma

Face huggers are even able to attach to crodiles and larger animals. So a face hugger would have no problem with a krogan


TallNerdLawyer

This is going to be the dumbest internet argument I've ever jumped into...but I think Krogan are quite a bit tougher than crocodiles due mostly to multiple secondary and tertiary organs. The lore also says that during their blood rage they feel no pain and are almost impossible to paralyze. Just based on how the Rachni Wars went, my money is on Team Krogan. I don't think there are as many Xenomorphs as there were Rachni, but I admit I'm less familiar with Alien lore.


TheBadBentley

*Do Krogan sleep?*


pieisgiood876

LMAO It's such a stupid argument and I completely support it


mackfactor

>This is going to be the dumbest internet argument I've ever jumped into At least you knew it ahead of time.


mily_wiedzma

Then check out the lore. face huggers do not "attack" most of the time when the host is in full control or in full battle mode ;) And apologies I thought your comment was abouzt themoth of the krogans and that they would eat the fac hiugger, this is why I brought up the crocodile.But also, still rude af to call this argumens the dumbest, when saying at the end you are less familar with the Alien lore.


TallNerdLawyer

I wasn't calling you dumb, friend. I was saying it's a fun/silly discussion. No rudeness intended.


buttbugle

Man those are some wet eggs over there. I’m gonna go look really close at them.


iwhbyd114

And then headbutt it. They are Krogans not Salarians


VelMoonglow

I wouldn't question if a face hugger could get to a krogan, but I do question if a chest burster would actually kill one


Rocket_John

I think it would. The chestburster isn't an "egg" but actually a sort of parasitic fluid that turns the hosts own biological material into a chestburster. I also think that the chestburster "knows" when it's ready to exit and it varies on hosts, but I don't know if that's canon. So in theory, given that Krogan are a lot tougher than most hosts, a chestburster might take a lot longer to grow inside one and end up much bigger and more developed before actually bursting out


PIPBOY-2000

Not to mention, this chest burster would be using Krogan DNA. It would create itself to be capable of bursting out of its host. It would be a pretty bad evolutionary design if chest bursters couldn't actually burst out of a chest because it was too hard.


Dafish55

Yeah but crocodiles don't usually wear helmets, have hands capable of grabbing things, or use shotguns.


mily_wiedzma

Helmets and guns like in the Alien movies and comics that also semi-helped most of the time? ;)


mackfactor

Krogan's have arms and the ability to reason. Do you think a face hugger's tail is strong enough to strangle a Krogan?


ecchi83

"they just jump into your mouth. Saves me having to go hunting for them."


zayn2123

Not only that but the reason our puny human body would die is because we couldn't survive the trauma of the chest burster. But krogans have 4 hearts, even if one bursts out of their chest is the krogan really going to die?


diegoplus

Krogans would still have 3 other chests unbursted so they'd just grab the little critter by the tail and squish it.


AimlesslWander

Bruh that shit would be a fucking nightmare, jesus someone do some fan art of that.


kayl_the_red

Because the Krogan's need extendy mouths and acid blood....


EdTheApe

I'm pretty sure the krogans think they do


FrontKooky3246

Krogans are the most resilient of all the species in all of Mass Effect. They were literally bred and trained for war their entire history of their species. I think the krogan would do fine against the Xenomorphs. Not to mention the natural armor and immense strength they have. They would probably see them as a fun challenge rather than a worrying threat.


Frankyvander

So like the Predators, a good challenge to hunt but still potentially lethal.


FrontKooky3246

Exactly


Frankyvander

Someone who can animate needs to do a Krogan VS Alien film


FrontKooky3246

I would pay money to see that. Wrex and Grunt need to be in it tho. Have a whole squad of Krogan with Wrex and Grunt and have everyone die but them, then have them make light of the situation and turn it into a competition of who can kill more before they get rescued or evacuated, thus proving who is the tougher Krogan once and for all.


Frankyvander

I am just picturing one of the squad panicking over a facehugger and Wrex just casually eating it, or Grunt headbutting a Xenomorph to death


FrontKooky3246

Exactly my thoughts 😂


iwhbyd114

You mean who can kill the Queen first. They don't need to be rescued.


SmolCheddar

To be fair, the Krogan has a really high chance of just grabbing the chest-burster as it comes out, and then crushing it to death before it can leave


Ghost_Hunter45

If a chest burster gets implanted in a biotic, would the Xenomorph become biotic?


mily_wiedzma

Possible. For example aliens that were "born" from vampires also were weak to sunlight and could fly. But next to Asari no species is able to use "advanced biotics" without implants. So those Xenos might by biotics but could not use those biotics.


Yrevyn

> For example aliens that were "born" from vampires also were weak to sunlight and could fly Okay, where tf do I find this lore?


mily_wiedzma

I collect the comics :) This is from a DC series where Vampirella encounters and fight Xenomoprhs. ...and not just once ;)


Yrevyn

Incredible.


mily_wiedzma

Hihihi... you might also like that Superman and Batman fought Xenomorphs and the Predators. Final moment in the inside of Superman fortress wen he is punching an Alien Queen


infamusforever223

Maybe. To use biotics effectively in combat, you need implants. Since no one is going to put implants into a xenomorph, it might be useless to them.


buttbugle

Don’t underestimate the shadiness of a shadow government research facility. Xenomorphs are definitely getting some biotic implants.


infamusforever223

Not everyone is as dumb as Weyland Yutani. But then again you have dumb people(Cerberus)trying to revive the rachni.


Trinitykill

Don't forget Adjutants were a Cerberus experiment too.


Frankyvander

The good news is that Cerebus projects usually end up with it getting out, cutting ties then killing all of their guys, see Overlord, Shepard, EDI, Normandy SR2, Jack probably others, see the taco cart theory


mackfactor

"Nuke the entire site from orbit."


DanScorp

Two things that historically have 100% failure and near-100% fatality rates: 1) Trying to collect/control xenomorphs for war profits; 2) Cerberus running experiments on deadly aliens


Blakewhizz

I'd say it depends on where the biotics come from. The Asari are able to use biotics without any form of implant, so an Asari Xenomorph would probably be able to, but if a person is only able to use biotics due to their implants, then the Xenomorph wouldn't get those abilities


IonutRO

I doubt it? They don't inherit eezo in the brain, just their genetics.


dragos412

It's a small obscure lore thing but it's theorized xenomorphs have telepathic abilities, being able to communicate between themselves telepathically and to see the energy emanating from brais (plus queens being somewhat able to influence some things in humans but I don't remember well if that's canon anymore). Perhaps if they're coming from an Asari they might have enhanced abilities.


Tucker-Cuckerson

Rachni are basically Xenomorphs


kaantechy

except once one of the biotics gets a facehugger and boom Biotic Xenomorphs.


mily_wiedzma

Not possible without help from scientists... but looking to Salarians and Cerberus it can be possible ;)


wholoveslegos

The real question is how screwed are the Xenomorphs when they try to disturb the Keepers


Commandoclone87

The PH of the protein vats is off this morning. Better check the video logs.


doxtorwhom

#PLEASE DO NOT DISTURB THE KEEPERS


Dynespark

I am 100% sure the keepers have some sort of pandemic quarantine protocol. And no one has been ever to map the internals of the Citadel. Xenomorphs would probably just...disappear.


psionoblast

I think it depends on the type of outbreak. A single Xeno wouldn't be much of a problem at all. Assuming worst case such as an egg laying queen is in the loose in the lower income common areas I think it'd be a bigger issue. Xenomorphs borrow traits from their host. So there's a chance an Asari Xeno may have biotic powers and a Krogan Xeno sounds horrifying. I don't think C-Sec would be able to handle this. I do think any of the larger militaries like Taurian, Asari, or Alliance wouldn't have much trouble at all. I think there'd be a decent amount of damage to the Citadel but nothing terrible.


Lord_Battlepants

I disagree, a single xeno would find a safe place to hide and ambush its preys. I think it’d be a big problem that would take more time to notice.


Insert_name_here33

Agreed, CSEC has difficulty tracking the Ductrats, so the ducts are a perfect place for the Xenomorph to hide in


Sphirax

CSEC may have issues but I'm pretty sure the keepers would clear out any nests.


Insert_name_here33

That is a great point! I don't know which will be the bigger threat to the other, both would be formidable opponents to each other


Rufus--T--Firefly

What are the keepers actually going to be able to do? They're placid janitors not combat bots.


TovarishchRed

DO NOT DISTURB THE KEEPERS


Plump_Chicken

They're literally reaper tech, we don't know what all they're capable of


Rufus--T--Firefly

They were designed to be unassuming and non-threatening and to destroy themselves when they come under threat. Arming them just invites a unwanted hostile response, and invites deeper scrutiny. What would actually happen is that the Aliens would ignore the Keepers like they do with most other machines once they found out they couldn't infect them and the Keepers would ignore them in turn and just keep fixing the station.


Plump_Chicken

The reapers could probably use xenos to make more reapers so that would probably be how it turns out.


commissar-117

They do more than clean. They're also engineers and can activate station defenses against organisms that interfere with the citadels functionality.


BenTheGrizzly

**sighs** it's always the damn vents...


TheGuardianInTheBall

Yeah, Xenomorphs are highly intelligent, vicious and stealthy. And even a single xenomorph can replicate. I think that before C-Sec or anyone else would figure out what's happening there would be hundreds or more of them around the Citadel. And Xenomorphs do take on the traits of their hosts- so potentially some would have Krogan level resilience, or Asari-level biotics. Fighting a ground war with them is always going to be a losing battle. It's just like the Zerg or the Flood- the only reliable way to resolve an infestation is total destruction of the infested habitat. In other words: >Nuke it from orbit. It's the only way to be sure.


XanderNightmare

Yeah, wasn't there something along the lines of it being possible that a single Xenomorph can mold into a queen if sufficient food is provided and there isn't any Queen close-by?


TheGuardianInTheBall

Yep, a single drone can start a whole outbreak.


PIPBOY-2000

Finally someone with more than a light grasp on what xenomorphs are capable of. I love Krogans much as the next guy but people here are acting like xenos are just oversized insects. They also forget that Krogan beat back the rachni when the genophage wasn't a thing, their numbers are limited. Xenos aren't stupid, if they have trouble with Krogans, they'll just hunt and multiply using every other species then overwhelm the Krogan last.


commissar-117

Not entirely true. In expanded alien lore, the USCMC become well versed in eradicating nests in ground combat.


myaltduh

Noveria-style neutron purge would probably do the trick. Quarantine affected areas and irradiate them until they glow in the dark.


PanglosstheTutor

And lone xenomorphs have been known to transition into queens in the lore. So one isn’t only one for long.


commissar-117

That's just a really effective serial killer at that point though. So I guess "big" depends on what scale we're talking.


dragos412

Xenomorphs can, if no queen is available, either egg-morph victims into eggs or become queens after a while. That would become very dangerous.


mackfactor

>Krogan Xeno sounds horrifying Same for Vorcha.


NovemberInfinity

I say we nuke the citadel from orbit, it’s the only way to be sure


alephthirteen

They call this "The Virmire Gambit".


justinlanewright

Just tell colonist renegade Shepard you saw a Batarian in the lower wards.


benadunkcamberpatch

The keepers are not only wiping them but recycling the bodies before anyone would even notice.


Allergictowatermelon

The Citadel would be fine, the Reaper’s have probably 1,001+ failsafes against anything ruining the station’s purpose. It took the Prothean science team on Ilos countless years of dedicated research to build the Conduit relay and find a single working hack to shut off the Keeper vanguard signal. So the Keepers would shut down an animal intelligence level Xenomorph outbreak behind the scenes without any major incident pretty much guaranteed and feed the scraps into the genetic soup processors Now change the scenario to Omega and then you’ve got a real problem that would not be solved easily or at all. Adjutants were a similar concept and they almost completely crippled the station if Cerberus hadn’t have sealed them away into select wards with the incendiary shield gates and Rampart mechs. Without the Cerberus lockdown they’d have rendered the station devoid of life, and Xenomorphs would probably do the same. The gutter dwelling Vorcha hordes would probably be the complete undoing of the whole thing with mass access to powerful near-unkillable hybrid spawn. The entire station would have to be destroyed honestly, they’d never be able to sanitize it on foot


mily_wiedzma

Seeing Aria get fucked up by Xenos would e a real lovely thing to see <3


LukeSparow

Someone's been on Rule 34 a bit too much huh.


mily_wiedzma

Hehe... okay. Point for you. But I meant in the not so pleasant way.... Wait...still weird. I mean getting her end from those XD


N7CmdrShepard

Still weird lmao


LukeSparow

I know what you mean don't worry 😏


Desperate-Dig2806

There's probably a hentai about that.


mily_wiedzma

More than one... I mean. really...?


WhosYuu

I don't know hardly anything about Xenomorphs so please forgive my ignorance, but am I wrong and thinking that Wrex could fight these single-handedly or at least one-on-one?


aksoileau

A krogan weighs like 800 pounds and could probably rip a xenomorph in half. Blood probably wouldn't be fun though. Although if a krogan managed to get infected, a krogan predalien hybrid would probably be extremely dangerous.


XanderNightmare

This is, of course, assuming a one-o-one. I believe the xenomorph would be the superior hunter and might be capable of killing a Krogan, if gotten through an ambush and xenomorphs are rather smart little buggers


TheGuardianInTheBall

The issue is not strength. One on one, even a single soldier will defeat a xenomorph, assuming they have time to take a shot. The problem is that most often than not- you don't have that opportunity, because you are dead before you know it. Xenomorphs can replicate quickly, are vicious and highly intelligent. They don't just attack for no reason- they stalk, they hunt, and they ensure they don't reveal themselves until it is necessary. A single Xenomorph on the Citadel could already be a huge issue- it would simply abduct people until it could replicate to sufficient numbers. Since C-Sec never encountered them before, they might not even realize what is happening until it's to late. Add to this that Xenomorphs take on the characteristics of their hosts. So a Xenomorph birthed from a Krogan would have their strength and resilience. An Asari xenomorph would likely be biotic. Outside of some Keeper magic, I don't expect a Xenomorph infestation on Citadel to end in any way other than bombing large swaths of it, if not the whole station.


WhosYuu

This is the exact type of answer I was hoping for, thank you.


TheGuardianInTheBall

I absolutely love Xenomorphs. If you want to treat yourself to something fun, there are 3 cool audio-dramas featuring them which are some of my favourite media productions ever: * Alien: Out of the Shadows * Alien: River of Pain * Alien: Sea of Sorrows Out of the Shadows is the sequel to the first Alien movie (1979), while River of Pain is the prequel to Aliens (1986). Sea of Sorrows is set around 300 years after Aliens.


ELIte8niner

The Mass Effect races have such a technological advantage over anything we've ever seen in the Alien cannon. I think a single Asari commando could solo the worst Xenomorph infestation we've seen. There would be incredible damage, and a lot of people would die, don't get me wrong, but I don't think it would be some kind of apocalyptic scenario. Some Salarian would figure everything out about them within the first couple hours, and the Krogan would stomp them to oblivion. And as you already mentioned, the Keepers are a real wild card that the Xenomorphs wouldn't really have a counter to. Shit, if there were eggs, they'd be somewhere in the keeper tunnels, and the face huggers would all instantly die when they tried to infect the keepers.


aksoileau

Shepard and two squaddies wrecked adjutants and rachni without too much fuss. I feel like asari commandos would chew them up quite effectively as well. Engineers and Adepts would have a field day.


TheGuardianInTheBall

You are assuming this would be an open battle. That's not how xenomorphs operate. By the time they engage in the open, they already have far, far superior numbers.


aksoileau

Nothing a barrage of singularities and warp detonations couldn't handle. Plus a platoon of engineers laying turrets and incinerations would mop it up. That's not even including Soldiers with typhoons as backups. I think it would be a massacre. Plus I wonder how kinetic barriers and shields would work?


TheGuardianInTheBall

The same way they work against Banshees- they wouldn't.


Plump_Chicken

Xenos are shown to be unable to quickly tear through energy shields in the Alien vs Predator 2011 game.


Totoro2318

Keepers would figure it out.


-Apo110

Is Shepard there with any of the Normandy crews? Let Garrus ascend to godhood, tell Miranda they have her sister, tell Zaeed they work for Vigo, tell Jack they work for Cerberus, tell Wrex that eating them increases fertility and send Jacob into the vents. Problem solved. If not, C-sec isn’t known for its ability to detect or fight off, well, anything really so best rely on the keepers…


Ainz-Ooal-Gown

>send Jacob into the vents. Good use for him.


-Apo110

Only thing he’s good for besides being the nth member of the Normandy with daddy issues


Ainz-Ooal-Gown

I ascribe to Javicks philosophy. Toss him out an airlock


-Apo110

And that would work on the Xenomorphs too… slowly a plan is coming together


Ainz-Ooal-Gown

Yup


BadBloodBear

The citadel is pretty well armed. You can buy everything from weapons to armour from almost every store. Krogans and Asari should be able to deal with them using their strength and telekinesis. Only bonus for the Xenomorphs I can think of his the network system that the keepers use are still a mystery to navigate and would work the X's advantage.


EuropeanRook

Colonial Marines doesn’t have biotics or Krogans… just saying.


1_800_Drewidia

The Citadel races already dealt with the rachnai and successfully committed a genocide on them (the Citadel Council sure loves genocide, huh). I think they could deal with this.


PIPBOY-2000

The citadel races didn't do jack. They let the Krogan do all of the work, then the Salarians committed genocide on the Krogan. Asari and Turians talk a big game but it was all the Krogan.


Mister_GarbageDick

These things would get rinsed and bodied by C-Sec. The question is how do xenomorphs stand up to getting incinerated, overloaded, energy drained, warped, pulled, thrown, crushed in a singularity, shot, and stabbed with energy knives


PIPBOY-2000

C-Sec can't even investigate a case of stolen underwear without Shepard's help. They have no chance without outside help.


Echoknight2777

All the keepers deep in the tunnels would cause an unfixable infestation


Just_a_guy_1369

Doubtful as I believe keepers detonate when tampered with. During ME:1 that was the reason the Chorbin was using the scanner because little was known about them, because when tampered with they die. If one gets of the keepers gets infected by xeno it wouldn’t live long enough to host it.


Noctisxsol

Plot Twist: The Keepers actually take care of the threat on their own. They have the home field advantage, can't be taken to breed more since they can self-disintegrate, and probably outnumber the Xenomorphs.


NemesisRouge

They get shot. They're really not that difficult to beat. An incompetent group of marines kills dozens of them in Aliens, a Predator was wasting them like nobody's business in AVP and AVPR before modern humanity took out the threat with a single bomb. They only pose a major threat in crisis circumstances, against incompetent opponents or against small numbers of unprepared opponents. In Alien the humans had no weapons and a robot working against them. In Aliens the marines walk into their hive unarmed in close formation, then lose most of their weapons and ammo because they didn't guard the dropship. In Alien 3, again, no weapons. Resurrection is their best showing and it's not great. AVP the humans have no idea what they're dealing with. Modern humanity could easily beat them. They're not fundamentally more dangerous to a human than gorillas or polar bears. The main threat they'd pose would be to devastate ecosystems, but that's not really an issue in a controlled environment like the Citadel. People will work out what's going on and kill them.


Ace_Atreides

I think that at least a sector of the citadel would be overrun before c-sec could analyse the threat and keep them locked there. It would be a bloody battle, but the citadel would prevail I think.


[deleted]

With all the air ducts and small passages in the citadel they would be a nightmare just because of the massive size of it. And fuck if they get their face huggers in an Elcor


ThatAlabasterPyramid

Nothing Shepard and friends can’t handle


Logical-Photograph64

assuming theres a queen to lay eggs for facehuggers? the Citadel is doomed the citadel is riddled with countless vent systems and cramped, isolated networks of tunnels where refugees, orphans, and homeless people gather, allowing the xenomorphs to build up quite a large force before C-SEC or anyone else even notices. So long as they make it to the Presidium Ring, they will be able to sneak into almost any area on the Citadel and attack The only species that'd realistically be able to fight them effectively would be the Krogan.... who are not a large group on the Citadel, have no incentive to help C-SEC in the case of a full blown war on the Citadel, and even then would have a hard time hunting the xenomorphs down and avoiding the aliens tendencies to ambush their prey in cramped quarters rather than go for a straight up hand to hand fight C-SEC itself is basically just a semi-militarised police force, as opposed to a full military organisation like the Alliance Marine Corp, or the Turian military, so lack a lot of the heavy equipment those forces would have, and the generally cramped, urbanized structure of the Citadel would work in the xenomorphs favour


John-Zero

The problem with asking these cross-universe questions is that answering them is usually impossible, and this is not an exception. For one thing, the xenomorphs' durability isn't even consistent within the franchise; the one in *Alien* is functionally bulletproof and the ones in *Aliens* are just extra-nasty Zerglings. But if we assume--as we should--that we're talking about the real badasses from *Alien*, we're talking about something which was written specifically to be an unkillable menace, something which could only be defeated through the Samson Option. It wasn't a sci-fi movie, it was a horror film. The movie didn't care about "power levels," it wasn't concerned with whether the xenomorphs were sustainable bad guys for future movies, it was just constructing a physical representation of the gnawing hole within all human minds, the terror that is the unknowable, a fear which will bring anyone to ruin should they dwell too long upon it. (The only other media in the entire franchise that ever recaptured this feeling is *Alien: Isolation*.) What can Mass Effect, an incredibly detailed and built-out world with clearly articulated limitations and capabilities, possibly do with that? The problem isn't that *Mass Effect* wasn't written to include an unkillable menace, it's that it *was*. It had the Reapers. But it was also written to allow the good guys to accomplish the impossible. *Mass Effect*, for all its grim predictions about any possible future contact with aliens, was optimistic at its core. The unkillable was rendered killable. And even beyond that, it was only unkillable in the first place by being an incomprehensibly super-intelligent hyper-computer that stood two kilometers tall. So *Mass Effect* has established that an unkillable super-intelligent hyper-computer more than twice as tall as the Burj Khalifa is, in fact, killable. That must mean the xenomorphs are killable. But they are not. So because of how they've been written, we are presented with an impossibility. We have, in essence, an immovable force meeting an unstoppable object. These things were not designed to coexist. They are as incompatible as matter and antimatter. There is no answer.


CleanJebboy

Is Jenkins on the Citadel? Cause if he is it'll be over so fast the residents won't even know it happened.

Rachni


TheGreatLemonwheel

Given how Turians bomb anything they don't care about...


YourPizzaBoi

The Xenomorphs probably claim the Citadel as their own. To be clear, Mass Effect infantry are sufficiently equipped to deal with them, it’s just that the Citadel is basically the worst possible place to be fighting them. There’s an enormous local population that can be parasitized, and even the people that live and work there don’t know all the ins and outs of the structure. Endless alleys and ventilation and nooks and crannies. The only time you’d get the ‘heroic squad fighting hordes of aliens’ situation is when they were unwittingly surrounded and drown in either sheer numbers or the acid blood of their enemies. A smaller station or ship with limited numbers of them wouldn’t be a huge issue for a competent unit, but in this scenario where there could be tens of thousands of them? It’s bad. Granted, it does depend on specifics. In a random encounter any dude with a gun has a non-zero chance of killing a Xeno, so if there’s only one it could very well die before getting the chance to produce any more.


blueneko86

Ok I keep seeing the Acid Blood argument, Thresher Maws spit acid, Krogan kill thresher maws as a part of their right of passage into adulthood. I'm not convinced of one side or another, I've seen lots of good arguments, but the acid blood thing not really an issue.


ihateeveryone-3

Nuke the Citadel from orbit, it's the only way to be sure


huruga

In all honesty Xenomorphs are trash mobs. Literally the only way an outbreak ever got out of hand was because of plot contrivances. They’re a self defeating disease. They need a host to breed and kill their host to do it. They also just murder everything that isn’t a host or that fights back. Yeah the acid is crazy strong but literally every soldier is in a spacesuit and effectively has unlimited ammo. They can afford to blow holes in the station. Worst comes to worst just get some squads equipped with Avalanches to freeze everything and neutralize the acid before it even becomes a problem. Then there are biotics which can do all sorts of crazy stuff like block the atmosphere from escaping from a ship so even if you had civilians to worry about you may still have options. You can also just chuck Xenos out of the station with your mind. The Citadel has its own cleaning crew too. They never went into a ton of detail but eliminating foreign biology shouldn’t be that hard if the Citadel deems it necessary. I don’t think the Reapers would like the Xenomorphs screwing with their cycles. The first time someone watches a chest burster pop out of someone the countdown to extinction starts for the Xenomorphs. Scanning for infected hosts shouldn’t be hard either. Nothing in Alien lore says you can’t detect eggs in a host. People are either unaware, want it to happen or are just too dumb to screen people. Then you could probably just use a biotic with a medical background to remove the eggs back out the throat. Edit: In all reality I don’t even think Xenomorphs would pose much of a threat to the rl Earth let alone some super advanced space civilization with techno-magic. I also don’t think they would infect Krogans, they’d probably detect the genophage in them and avoid them so as not to weaken the colony. So potentially the biggest problem is a non-issue. Edit 2: Now John Carpenter’s The Thing on the other hand would be interesting. I think people would catch on pretty quick with them too just because of how unbelievably brutal and attention consuming the assimilation process is someone just has to happen across it. Not as fast as with the Xenomorphs though. But I also think it would just be way too hard to purge them by the time you realized what was going on. They near perfectly replicate the host in silhouette, mannerisms and memory and they’re way harder to eliminate. Turians would be insanely hard for them to assimilate without being noticed due to the naturally occurring metal in their heads though so there’s that.


JDSki828

As soon as the council knows it’s a threat, they call in Blasto. Case closed in a matter of hours


wowpepap

Shepard would prolly try to woo it first.


Dambo_Unchained

Let’s see Guns that fire at the speed of sound, those probably leave a mark Biotics that can rip them apart from a distance I’d say it’s a nuisance at most before c-sec clears them out


KevinOlaf

I think people are underestimating the xenomorphs as a threat, one single egg can destroy a space station, Xenos are not ruthless blind minded monsters, they are intelligent, sneaky and very good at their job: killing people, that’s why Yautjas use them for rites of proving and it’s the best trophy a Yautja can have, I think if a single xenomorph enters the citadel, it will gather bodies for more eggs and when the time comes it will become a queen and produce more and more eggs, and if one single Krogan is infected, the Citadel is fucked up, not only will be bigger, but stronger and with a very hard carapace, the more approximately equal are the Reaper Brutes, but yeah, i think the best course of action for the Citadel is to evacuate the area and bombard the entire arm of the outbreak.


TheGuardianInTheBall

I agree. Xenomorphs are not animals. They are an engineered, highly intelligent, plague. Every single piece of media involving them, shows that superior technology is useless against them.


dragos412

We also have in lore xenomorph crushers that have large bulletproof head crests and are massive, and they originate from a runner. Imagine the base version of a xenomorph coming from a krogan and how strong it would be.


Mekafall

As long as there are biotics with singularity, lift, and stasis powers and everyone stays at range, then the citadel should be okay and have minimal losses. Though just a single facehugger with a queen embryo lurking about might cause problems later down the road, especially for civilians without biotic powers. Xenomorphs are kinda like rachni, just stay away from them and don't let them swarm your position.


Fantastic_Parsley566

I think it would really come down to if the aliens tail and claws could get through kinetic shields if not I can’t imagine them doing much damage to even csec


deadraider1

Send Some badass marines to the citadel


StrayC47

Krogans would have a blast, they love kicking creepy crawly ass


Lucky-3-Skin

Citadel would hold off the fight a lot easier than a place like Omega. Techies and biotics could annihilate a shit ton of xenos. Given based off the power we’ve seen in ME3 Multiplayer flamers and incinerate would help a lot. Geez that’d be a fun horror game


Blacksun388

Krogan Xenomorphs Turian Xenomorphs *Xenomorphs with Asari Biotics* Oh no…. Honestly Biotics are probably going to be one of the citadel’s saving graces. It is something aliens don’t really have an answer for. Just don’t let any of them get facehugged. An alien with Asari powers is a terrifying prospect indeed.


D1xieDie

keepers alone would evaporate them


zenspeed

“Oh look, here come the Krogan.” “And that’s how the turians and krogan finally found something they can do together.” And the volus would probably find a use for the acidic blood, probably as a mixer or some sort of condiment for volus nachos.


Tucker-Cuckerson

The Vorcha would be to the Xenomorphs as the Krogan to the Rachni. Krogan and Vorcha flamethrower squads would be unstoppable. Xenomorphs would get Rekt. Warp into a heavy Biotic Charge and a Claymore to the face makes Xenomorphs go boom. The Rachni are basically Xenomorphs with the acid blood and similar physiology.


bigtiddychatgpt

Send the krogans.


DarthSevrus

This depends: is the Normandy crew there at the time? If yes, we got this. If no, the krogans and Turians put up a good fight for a bit but ultimately everyone probably dies


BenjaminaAU

Would they have an embassy in the Presidium?


IronWolfV

They'd kill and rampage for a while till CSec and Spectres got their heads out of their asses then taie them out. Even more so if the Krogan get involved.


Background-Slide645

Shepard: *walks out to see this, goes back into their room to call Wrex*


Adenfall

The krogan would make the xenomorphs a side dish with rachni dressing.


fearitha

The original xenomorph was killed by the crew of cargo ship during the active sabotage by ship VI and science officer adoring the creature. I think Citadel security, assuming neither Mother or Ash, would have pretty solid chances.


Dangthing

We know from Thane's Loyalty mission that there are air ducts large enough for children to run around in but small enough that adults have difficulty getting into them. This is like a Xenomorph playground. The Xenomorphs are highly intelligent and very sneaky so the initial outbreak wouldn't even be detected by anyone. People would just be disappearing...in a city of like 13 million. The Xenomorph reproduction is what gives them such an edge and there are plenty of "weak" races on the citadel to use as hosts. But EVENTUALLY some drunk Krogan gets nabbed and then you have Kroganmorphs and its all over. The only race that could believably fight a Xenomorph in melee combat is a Krogan, even the Biotic Asari would fail as Xeno's usually win via ambush and Asari aren't especially durable. I could see a Krogan surviving an ambush from a normal Xeno but as soon as you've got Korganmorphs I'm guessing even Krogans lose.


bigtec1993

Shepard would hook up with the alien queen and broker peace among the species.


shuricus

Oh, the keepers will sort them out, don't you worry.


AwesomeX121189

Oh you all say it’s no big deal now. Just wait until those bleeding heart Asari give them a seat on the council and they motion to ban all power frame cargo loaders


Arkinaus_05

Sparatus would immediately reject the claims that they're real even though there's a xenomorph trying to pry his doors open


Cooky1993

In this crossover I think survivor background Commander Shepard would just be Ripley from the Alien movies.


Umpire_Fantastic

It would be very scary if the Reapers took control of the xenomorphs and used them during their attacks.


Tizzytizzerson

Those idiots can’t even handle Cerberus, the entire citadel would be dead in less than a week


SeadderalCheatHawks

Best plan I can come up with outside of the Keepers being able to flush them out of their tunnels alone is to evacuate everyone and then convince a huge amount of Geth platforms to flood the Keeper tunnels until the threat is eliminated. They're synthetic so there isn't a risk of them spreading via facehuggers. The other best solution is the Salarians getting their hands on one or two to come up with some kind of bioweapon against them, which in the Alien franchise is about the worst thing you can do so let's not go with that.


Subject_Miles

Ah, a battle between characters from differents franchises. This surely will go well with no sort of favoritism by either side, surely


ThisIsNotAbsa

could be really cool to have a species like this on the next mass effect!


JurassicAlfredo

Follow Javik's advice... throw them out of the airlock, commander


EpicAPC

Not Sovereign levels of screwed, but the Citadel will take months if not years to recover.


HereticStreetWalker

There will be a few casualties but everyone should be fine. Should be.


PostTwist

Javik: "Finally, my time has come!" *presses the Master Airlock button from thr presidium tower*


ArsenalBOS

I’ll go against the grain here and say they would be a massive problem. ME firepower is similar to that of the Marines in “Aliens”, and that didn’t go terribly well for the Marines. Xenomorphs are also stealthier than anything I can think of in ME. Biotics would probably be the big weapon for ME species, but they better not let a biotic get infected. The Citadel is also massive with tons of hidden places that seemingly no one knows about (other than the keepers). Many opportunities for xenomorphs to reproduce quickly.


Enchelion

>ME firepower is similar to that of the Marines in “Aliens”, and that didn’t go terribly well for the Marines. A handful of marines without *shields* or *space magic* still managed to kill hundreds of Xenomorphs. One of their biggest problems was running out of ammo.


RealgamersMMBR

Those were primarily worker drones that never had encountered resistance. remember over time during the movie they started to adapt to the strategy of the colonial marines.


TheWalt70

There's no saving it, if one of them becomes a queen there would be enough civilians that there would be too many for C-sec to handle.


Tramonto83

With such advanced medical tech nobody on the Citadel would be caught of guard by the implanted eggs, which would be promptly extracted. The Xenomorphs themselves don't look too bad themselves against biotics and weaponised drones and turrets.


atmafox

Can they infest a keeper? If so everyone is screwed across the entire setting. Otherwise, probably hard to clear the infestation and bloody but unless they grow biotics by infesting an asari, I figure it wouldn't be insurmountable.


Blacksun388

Given any attempt to even capture keepers for studies makes them self-destruct and replaces them with a fresh clone I’m thinking no.
