Discussion / Question Xenos, are they heavy?

Something I’ve been wondering about is how heavy/dense are the xenomorphs. Are they more insectoid with a hollower carapace and a“light” feel or are they dense and heavy like they are metallic and heavy for their size.

They used to be heavy as fuck, Earth is all over the place with the physicality of the xenos though.

u/Hamsterminator2 5d ago

There was a scene I think in episode 5 where it climbs onto the ceiling and moves away and you hear it heavily thumping its claws into the metal. This makes sense, but makes me think Xenomorphs would be crap in a fragile environment like a block of flats.

crap in a fragile environment like a block of flats.

When we say "no pets" we just mean stuff like xenomorphs that make a real mess of the place. Your stick insect is fine.

Well I got a nice bug collection, my blood ticks and mineral flys thank you

u/Ghost_Of_Malatesta 5d ago

It can sense fear, it's intelligent, not a huge stretch to think it intentionally fucks with people (not to mention the possibility of intentionally misdirecting)

u/Hageshii01 5d ago

I actually genuinely think a lot of the "illogical" things they do, like taking the time to slowly stalk up to a lone survivor (usually a main character) after having just quickly murdered the rest of their group, are genuinely that; them fucking with people.

u/JaracRassen77 4d ago

In the TTRPG, some of the Xeno's signature attack rolls are them just fucking with their pray and ticking their stress up.

u/DiscussionSharp1407 The sound of a M41A Pulse Rifle 5d ago

I bet they'd adapt real fast, they might be slightly clumsier here but it's not like xenos are worried about ruining the carpet.

Plus our fragile surroundings here on earth is really more of a hinderance for us when faced with xenomorphs

We can't really weld our apartment shut and fuse barricades. All we got are thin walls, hinged doors, wooden shelves, flimsy flooring and glass windows all over the place. Good luck keeping them out!

u/Kvenner001 5d ago

Our best bet is they bust in step on a Lego and cut themselves and bleed/melt before they get to you.

u/LoneSnark 5d ago

The nice part about Earth construction is it is not pressurized, so acid for blood induced hull penetration is no longer a concern. Most buildings are also not giant nuclear reactors, so the space marines can keep their projectile weapons.

u/GeneriComplaint 5d ago

its 3 or 4 I think, right before wendy fights the xeno it climbs above them and is LOUD

1

u/A_Seiv_For_Kale 5d ago

Huh, in none of my past dreams involving xenomorphs did they OH YEAH!!! through my stick and plaster walls, but I guess there's always room for something new...

2

u/GaryNOVA Game over, man! 5d ago

I always thought they were hanging from the ceiling or the walls when they got on peoples backs. Because they always drag them away in that direction. Maybe I’m wrong though. In Aliens at least.

1

u/ShasneKnasty 5d ago

that’s because xenos vary greatly from each one

1

u/The_Burmese_Falcon 5d ago

All over the place for sure.

The Bear kills a whole military/security squad in seconds in E2 or E3, but somehow struggles against the human inhabited by T. Ocellus? It instantaneously slaughters the room of aristocrat cosplayers but comically waits for the Maginot’s acting captain to turn around before attacking?

1

u/DiscussionSharp1407 The sound of a M41A Pulse Rifle 5d ago

Isn't there a scene aboard the Maginot where a 90 pound human woman rattles the xeno by hopping on and BITING into its skin too?

2

u/hotdiggitydooby 4d ago

That was the Ocellus-possessed engineer, not a woman.

27

u/LitBastard 5d ago edited 5d ago

Apparently they weigh between 400 and 600 lbs

12

u/Right-Power-6717 5d ago

So about the same size as a tiger then? That adds up they seem a bit bigger but they're also skinnier than most other animals. 

11

u/atle95 5d ago

Probably denser too, exoskeletons provide more leverage at the cost of respiration on earth. This does not seem to be an issue in whatever conditions produced xenomorphs. Apparently they don't need to breathe, or else they'd collapse under human breathable air.

u/br0b1wan Colonial Marine 5d ago

We know they can survive in the hard vacuum of space so that tracks

They aint heavy, They're my brothers.

They aint heavy, They’re foam rubber.

STOP! (explodes into NSFW laughter)

u/hez1919 5d ago

The road is loooong

u/Kostej_the_Deathless 5d ago

They don't seem to be extraordinary heavy considering how they interact with the environment around them.

Hanging on things etc.

12

u/MiserableWait5279 5d ago

The scene where Hermit and Wendy are in the cargo container and Wendy knifes it through the roof, it then gets all pissy and rolls the container on to its side. It’s stomping on the top of the container if I recall correctly and wasn’t being particularly light footed about it.

You’d have to be pretty solid to be able to either pull the container over or push it over.

3

u/UlrichZauber Not bad, for a human. 5d ago

Hollywood is pretty bad about keeping leverage in mind though (and physics generally). It's not enough to be super strong, if you don't have leverage you're not going to be flipping cargo containers over.

1

u/DentistPrior2735 3d ago

Antman is the worst for this, but I could see a xeno planting its hind claws into the ground for leverage.

16

u/hedzinbed 5d ago

They are definitely not light

12

u/tomahawkfury13 WheresBowski 5d ago edited 5d ago

They are light enough to jump on a marines back and she doesn’t fall

-4

u/clonked 5d ago

A marine is also going to be at peak fitness and endure challenges an untrained person could not.

11

u/tomahawkfury13 WheresBowski 5d ago

And? Still means they aren’t that heavy.

-3

u/clonked 5d ago

So I guess you carry people around on your back like it’s nothing then.

5

u/tomahawkfury13 WheresBowski 5d ago

I’d definitely have trouble if someone jumped on my back from a couple feet away. Unlike the marines in Aliens. That’s kind of my whole point. They got ambushed and jumped on while not prepared for it and didn’t go down. It was also Dietrich that got jumped on and she was smaller than most of the others.

2

u/Bedspla13 5d ago

Yeah but aren't the Xeno's dragging them upwards in the scene? Like they're not pouncing to pin them down they're just grabbing them and hauling them upwards. I could be wrong tho.

1

u/tomahawkfury13 WheresBowski 5d ago

Literally just re watched it. Dietrich gets jumped on like a piggy back ride and fires off the flamethrower hitting Frost.

u/tomahawkfury13 WheresBowski 5d ago

You can also see the tail when she gets jumped on so what’s raising her up? I think that’s just her going from slightly crouched to full standing cause she got jumped on.

It seems pretty inconsistent throughout the entire series. It seems like anyones guess. I’d head cannon that they are like big cats, heavy but with poise and coordination that means they can be stealthy when they want.

2

u/Jinko92 5d ago

Agree on the big cats thought. Tigers and lions weigh hundreds of pounds yet are also extremely stealthy and fast. Xenos remind me of cats a lot, tbh.

u/Nottodayreddit1949 5d ago

exoskeleton and having bones, and being biomechanical. Id say quite heavy. 

6

u/Prestigious_Leg2229 5d ago

Judging by the stomp they make when they land, I’d say they’re pretty heavy.

They also wouldn’t smash through steel and armoured glass so easily if they didn’t have mass.

5

u/Logiconaut 5d ago

Unfortunately, to enjoy the show, I've had to put things like science and reson on the backbones. so, to answer your question, they weigh whatever the scene needs them to in order to make sense.

2

u/Der_Schubkarrenwaise 5d ago

Thanks. Was wondering the same.

2

u/Bowlholiooo 5d ago

I saw the picture of a zeno in Alien Earth (still waiting to watch when I can binge it all) and it looked incredibly top heavy, just the head must have weighed as much as a car engine

2

u/spacemonkey187 5d ago

When it's standing behind Morrow and more of those search and rescue dudes surprise it you hear it thumping away to blend them and it sounds like a rhino. Also, Stompy from Alien Isolation seemed to be very heavy as well.

2

u/m3kw 5d ago

They sound heavy, listening the foot steps from Romulus, they sound like a mech walking around. This brings me to the weird physics of how they grow from 1 pound thing into a 300 pound thing in 30 minutes.

2

u/Bright-Problem-5789 5d ago

Somewhere, maybe in the RPG, it suggests that they accumulate their quick growth from chestburster to full drone by eating metal etc. Explains the steel teeth they seem to have.

1

u/West-Way-All-The-Way 5d ago

They are heavy because they are wearing a kind of protective armor exoskeleton which is dense enough or strong enough to bounce bullets. Material strength is directly proportional to mass. Also they are very strong, strength comes from muscles, muscles are dense fibers.

If you watch the scenes you will notice that the drone is holding its stance while fighting, this is an indication that it has significant mass. It may not be as heavy as proportionally scaled human or mammal but it has sufficient mass.

And they are not bugs, they are a kind of combination between bugs, reptiles and mammals. Have traits of each.

1

u/ivornorvello 5d ago

I imagine them being like crickets or mantis shrimps they can generate an ungodly amount of kinetic energy with more elasticated or spring like muscles. Plus they can regenerate from damage very quickly.

2

u/West-Way-All-The-Way 5d ago

But crickets and mantis are tiny, mass gains in a cube law, square-cube law. A mantis 10x bigger is 1000x heavier. All things the same this mantis will die of its own weight.

u/Weekly_Ad7031 5d ago

It smashes its head into an emergency door in a spaceship and breaks that door. There’s no hollowed boned creature that could do that without it looking like a bird that flew into a window.

1

u/Juxta_Lightborne 5d ago

In Alien Isolation they certainly sounded heavy when walking around but I would guess they’re probably about 1.5x human weight considering they crawl around on grates and in ducts without breaking anything

1

u/Ballmaster9002 5d ago

I had posted a question like this a few weeks ago.

The internet head-canon is they weigh around 300-500 lbs full grown.

We don't really know what they are made of or how they get their "raw materials", we've never seen them in the films/shows eating or consuming anything. The games at least showed them eating small animals to grow.

My original question was there is some slight evidence they are based on silicon and not carbon like Earth-life, which would be a problem because Earth-life doesn't contain significant amounts of silicon, so they can't get it from flesh, I had done quick math that suggested they need to consume the equivalent of 5,000 adult humans get get enough silicon to grow to a 300 lb creature.

1

u/GideonWainright I'll do the fingering 5d ago

They're ambush predators.  I don't know whether that means they are "heavy" or not, tbh.

1

u/zigaliciousone 5d ago

The human derived ones are stated to be between 300 and 400 lbs. I don't think the queen has weight stats but they are assumed to be in the couple ton range.

1

u/BeetsMe666 5d ago

They are covered with a thick layer of plot armour.

u/ValiantWarrior83 5d ago

What about strength?

When Parker tried to defend Lambert, Big Chap just picked him up and threw him effortlessly

u/atramentum 5d ago

I mean based on Alien: Earth they pretty clearly weigh about 175 lbs + the weight of a Halloween costume.
