It seems that he intends to unite the now fractured dynasty’s and factions of the necromancy race under his rule once more, to infact guard biological life from this threat until such time as suitable beings evolve for the necron to possess and in turn regain biological form once more.
I can see the Tyrainds Can eat Necrons, I think the better question is DO they want to? The Tyriands are highly instinct based on many levels and the Necon's pure power is ANTI-LIFE. I can guess that the sheer presence of Death of a Nightbringer shard could possibly install fear long enough for the weaponary of the Necrons to kill the mass of Mostly Organic bugs.
"We're made of star stuff" - Carl Sagan All things in the universe are made from the same particles, reconfigured and resorted to be shaped into the building blocks of matter. If the Tyranids are able to 'break down and use' other matter beyond that of what has been dubbed 'biomass' for ease of lore and concept in a setting that changes with the stroke of a writers keyboard with every codex or novel release, there would be nothing left of any star system the swarm passes, and their fleets would be entirely unstoppable after a single solar system, the total mass of its star and what orbits its gravity feed to put it beyond the scale of entire segmentum fleets. Instead they only consume the 'organic' surface and atmosphere of planet that had been one of the lucky fraction to create 'life' in any form, which is well below a single 1% of its total mass, making the overall gains to the 'nids on the grand scale rather limited and even easily calculable with some quick math of how much they could possible add to their collective biomass from our galaxy, or the closest number of galaxies to us. Therefore, if we go and say the nids can both eat and gain something from living metal, we would have to also let them eat worlds from crust to core, drink gas giants, and more than likely nom stars, which would make them beyond powerful and tip the balance of the lore. It is my belief then that the tyranids gain nothing other than nano-machine food poising if they consume living metal, unable to adapt to as a cellar level war goes unseen within a hive ship/ripper's guts. and any non-organic materials they devour remain inert and eventually are ejected from the creature that ate it at a later time, perhaps rendered down into slag by bio-acids, or just little more than carbon.
Now the real question is there a way to make the Nids taste like crabs or shrimp. So my hungry guardsmen will be happy to see them on the battlefield. As a feast in the making.
I think necrodermis is made of nanobots. The tyrannids can't eat necrons for the same reason you can't chew and swallow a watch, and then crap out a fully functional watch.
'nids aren't humans. Even on earth there are organisms that can in fact eat metal. As for the nanobot issue: So are 'nids. The smallest Tyranids are Phagecells, which are a in between of virus and bacteria. The power of the Necron nanomachinery lies in its reaction speed. However Tyranid organisms have been shown to adapt to even the life Eater virus or Nurgles plagues. At least the former requires near instantaneous reaction speed. The Necron Nanobots take longer to do their thing, as the case with the kroot shows.
I think this is a matter of scale, the word nano is far beyond most organic systems. If a entity is a few nanometers. It will be so small that it can pass through cell membranes freely. Viruses and bacteria are huge in comparison.
It's obvious that Warhammer 40k exists on the premise of eternal war for the sake of keeping the table top game alive, alongside the inevitable power creep to keep people from getting bored over time. So it is somewhat inevitable that tyranids, a race designed around this concept, would eventually evolve to devour what makes them stronger. What interests me most is not how hopeless it sounds when solely describing war with tyranids, but also the power creep of other factions against them, one of your other videos describes the counter threat of the divine emperor deity rivaling the power of chaos, along with gork and mork, and likely even the hive fleets, because it indicates perpetual stalemate despite power creep. I would be very interested to know if the hive fleets are running from something worse in their own galaxy, or about the force that drives the norn queens.
I find the kroot story kind of contradicting. How could kroot eat necrons if the all phase out if damaged beyond field repair? And since when do they eat metal in the first place. The nanoscarab plague is a logical consequence. I would think the with the genes of the ferrobeast they found a way to make bionical material out of metal. Otherwise, didn't the ferrobeast already have a metal skin?
I'm a big fan of Arch's theory regarding the Tyranids - that they're another creation of the Old Ones, originally intended to collect the organic essence of all life and store it for after the Necrons died off or went to sleep. Problem is, like with the Krork, the Old Ones had no concept of control or an off switch.
Oh yeah, just hand the tyranid genetic material of species 8472 and make them even more powerful! Once they had it, and they could expend 50 ships to capture just 1, they would have no serious weaknesses anymore. Of course as a tyranid fan, I have no problem with this! The hive fleets shall consume!
@@evilspoon5280 It is worse than that - Fluidic Space is canonically an organic matrix the size of an entire universe. The Tyranids would be floating in a universe-sized bath of biomass. They would soon evolve vast fleets of Hiveships adapted to hoover it up in incredible quantities, and by the time they travelled (with Species 8472 genetics as a bonus) to other realities their numbers would be even more insane.
@@gregorygreenwood-nimmo4954 Tell me about it! An entire dimension that rich in biomass would be insane to let the tyranids into. Their ships would be so numerous they would blot out the stars across entire galaxies! Of course as a tyranid fan, I am not against this! The hive shall consume!
I like all your vids. But this one is above all your others. Just because you showed the wasp to back up a theory. (Fantasy thing set the far future. Here's a real life example.) Brilliant
The nekrons fought using what can pretty much be described as the absolute pinnacle of what technology can be, without reliance on the warp atleast while the actual components of nekrodermis is still ultimately just atoms and chemical bonds, more than capable of being broken down, I still consider it beyond plausible that the Tyranids would actually be capable of integrating the material in its original way, unless of course, that whatever controls the hivemind, has an intelligence that can rival the combined knowledge of both the entire nekron race and the C'than. Without the ability to reverse engineer it or understand it, it seems pretty much impossible for the tyranids to incorporate fully functional nekrodermis at all (beyond using scraps as cheap expendable armor, as opposed to a grown carapace of the stuff)
Haha this was the theme behind my last color scheme on my tyranid kill team. A small hive of warriors that consumed an old necron planet. Glad to see some more theory I can use as backstory now
How do you no its not and this isn't the inquisitions way of keeping us in the dark by letting us all believe it's just a made up universe based on a board game.
We discovery channel now. I was not looking at the screen when you were talking about the wasp and was like "Yeah that is something from the 40k univer... Woah.. That's on my current home planet.."
Now I want to model a Hive Tyrant with a necron orb and gaunts with gauss rifles. I have 30 shots from this squad and they get back up after you kill them. They a supported by my new shiny Carnifex who is also unkillable and would get back up even if you tried.
They are not even the worst... not by a long way. Nature throws stuff out that is at least as nasty as Tyrannids in its own way... not as all consuming perhaps, but just as horrifying. At least to our sensebilities
I do. Imagine a Carnifex on one of those floating scarab things complete with a Gauss cannon. Actually thats all Iv'e got right now. The necrons are mostly metal skeletons, scarabs and gauss rifles, maybe a few vehicles but those are irrelevant.
Hello 40k theories (and anyone ells reading this). I am not to knowledgeable about the 40k universe but I recently read about some speculations about how the Death Korp of Krieg are able to replenish their numbers so quickly and one of the suggestions was cloning. This hypotysis was quickly shot down however when people pointet out how humans not naturaly prodused are more subsetable to the warp as the child lacks the natural protection provided by the mother during the pregnancy. This made me imedietly think about the primarchs and how they were not naturaly born but rather grown in, and i quot "gestation capsule". So could this mean that from the very start that the primarchs were inherently less resistant to the warp?
The primarchs were still far and above normal humans, so that theory doesn't hold as much weight. As well, the primarchs rebelling had more to do with their beef against the Emporer than chaos, with only hours and lorgar being truly corrupted for the most part
Very true. I have not read any of the Horus Heresy books so I don't know how all the traitor primarchs changed sides and thier reasones for doing so and my knowledge of the rest 40k universe is very limited so I can be very much in the wrong. I was merely making a suggestion that even as the sons of the emperor, it might have helped the chaos gods in some small way to get the primarchs on their side if the were cloned rather than born. Maybe influencing them to overlook certain details and things like that.
As well as the wasp there are deep sea, sea snails that use metals in the growth and construction of their shells and have essentially metal shells because of it.
It's an interesting theory. The only problem is that the new Necrons Codex specifically says that some of the Dynastys have taken to returning to Necron worlds after the hive fleets have passed by to gather all damaged and destroyed Necrons to either repair or breakdown their remains for future use. Nowhere in that does it suggest that the Tyranids are somehow absorbing the Necrons living metal. An interesting idea though for sure. =)
Tyranids are basically the Borg of 40k (consume evolve adapt move on in a hive). They COULD however adapt to consume living metal much like they adapted to fight creatures of the warp
Dont forget in 'Storm of Iron' a hive ship was infected with the Chaos Oblitorator Virus as a transport vessell, so if they have eaten a few of them aswell as the Necrons... carnage will ensue
It would be interesting if the hive fleet intelligence could understand how to use faith like how the Orks and Humans have. It might make troops similar to genestealers but focus on worship of the hive fleets, shadow in the warp, specific units, or all the above.
I think it is without question the necrons are the most powerful threat the Galaxy has ever faced however their lack of aggressiveness leaves something to be desired
Probably the missing 2 primarchs. "Eh.. can't really use you guys in my great crusade... here, take this webway to the next galaxy over and see what you can find".
They aren't fleeing from anything. The epilogue of the Horus Heresy novel Pharos clearly explains why the Tyranids are coming :) Sorry to disappoint you.
Regarding the beacon thing attracting the nids here. It doesn't fully rule out them fleeing something. Could be they randomly fled in terror and later the beacon indicated a good place to head to. Not read the book however so sorry if this is explicitly ruled out.
Whether or not they can do it, I'm sure the Tyrandis will give it their best college try once squishier food sources are exhausted, and if I had to bet, I think the infamously adaptable bugs would find a way sooner or later.
3rd ed Tyranid codex makes reference to 'magma borer' creatures thought to be variant of the Carnifex. Upon planetfall they burrow deeper and deeper until they release any deep magma for absorption. If they can absorb that......most elemental metals should not be difficult certain alloys may pose issues but long story short.......WE REQUIRE MORE MINERALS.
There are marine snails and worms that can drill their way through solid granite. There are other organisms that can literally dissolve rock, still others that can break down metals, including some that actually thrive on heavy metals most organisms would find lethal, such as Arsenic (yes, it IS a metal). There are others that can survive in heat and acidity that would instananeously kill most other living organisms, there are others, such as tartigrades, that have literally survived exposure to space, and survived well enough to breed afterwards, despite the massive radiation damage an unprotected organism would suffer from such exposure. I would not find it beyong the realms of possibility for the Tyrannids to in fact be able to do exactly that, as that is what they were *designed* to do. Just looking at Earth you will find organisms that survive in conditions that are frankly mind boggling, what other forms of extremophiles have the Tyrranids encountered. They have already consumed an entire Galaxy remember, an entire Galaxy worth of Genetic material they can work with.... That is even BEFORE they got started on this one.... They have already got ship sized bio weapons that can literally dissolve the ships of other races with streams of bio acids, that right there is consuming, that is basically EXACTLY what our digestive system does. We do not directly use ANYTHING we eat, what we eat is broken up into its constituent pieces, sugers into glucose, proteins into short amino acids, other compounds or elements into whatever form is most easily utilised. The body then uses those building blocks to build what it needs from them. It does not take a hunk of meat and attach it to your own muscles, it breaks that meat down into its constituent molecules, then uses those to build extra muscle if you are working out, or as you grow, or as old muscle simply dies and needs replacing. Consuming a Necron would be the same process, break it down into its constituent molecules, then siphon them up and use those molecules to create what the Tyrannids need.
@@alganhar1 problem is tho would it even be worth trying to eat a tomb world? The weapons of the crons tend to make things disappear rather well so to start the dead would be nearly useless to recycle as there adoms are blown apart
If given enough time then yes, I think the Tyranids could start to consume in part or whole Necrons. The more important question is, "What is that timetable?".
One thing I would wanna no is could the flayer virus be transmitted to the nids if they attempted to eat a necron flayed one would it evolve to suit the nids n somehow find a way to effect them via there psychic connection to each other.
Good to know. Damned necrons are always cutting through my yard, so maybe I’ll keep a tyranid on a long chain when I’m not home. STAY OFF MY GRASS YOU DAMNED NECRONS!
I am really scared/excited for the future of warhammer lore. Cause it is been escalating lately.. so many worlds consumed,craft worlds destroyed, the appearance of primarks and a eldar God of death
But Didn't Tryanid already got that Every Individual Work For the Greater Purpose Part? May be They will learn How Ethereal Class manipulate their subjects?
Do you think something like the blacklight virus from prototype, could be a danger or a boon to the tyranid race? Also do you think someone like Alex Mercer or James Heller would be like a straight up hard counter to tyranids?
Of all the forces extant in the galaxy, it feels like only the Tyranids can present an equal opposition to the Necrons, and vice versa. If it ever happened, it would be a sequel to the War in Heaven; the Wars of Hell.
Been wondering about this for a while now. Thanks for covering. Could a hive fleet devour and absorb Necron traits? Scary thought. Could they possibly do the same to a C'tan shard? Terrifying thought.
I really just don't know. The way tyranids adapt could, I suppose, make about anything at least possible. If it ever did occur though I'd truly fear what the result would be.
S Blair or maybe the tyranids would serve as a screening force for the outsider/hive mind? We know Ctan can eat other ctan after all, and it seems quietly confirmed he’s behind the nid hive mind. Nd he was the only ctan to not be shattered. Friend, I think you shouldn’t fear the Nids being able to consume ctan, but rather the outsider eating ctan.
I guess time will tell. Neither sounds nice though because either way, the galaxy would be done for imo. I mean, what's out there that would stop that?
You know like how chaos rhinos can have living victims grafted onto the hull. I imagine a tyrant carapace with necron limbs protruding from it. Still living but unable to be recalled due to the shadow in the void, there broken body's have been fused into the tryanid carapace, ever trying to rebuild them self inside, giving the carapace the characteristics of living metal. The carapace move around as if people were trapped inside, trying to get out.
Kaza ddum did they ever get around to successfully incorporating Necrons metal? I don’t know I’m just curious. I think...even if they did it wouldn’t be much worth. Here’s why, The reason (as I understand it) that Necrodermis is so good is because it’s not just metal, but “living metal” that operates within the Necron firmware and abilities: warping, electric exotic energy blasts, tiny scarabs that work as super AI but in the microscopic billions-which is why the living metal regenerates so quickly, because it’s essentially a billion billion little super AI workers-much better and more powerful than typical or even Tyranid cells. The tyranids wouldn’t even gain the exotic matter guns that the Necrons use. The Nids would walk away from the engagement with just more metal. No guns, No new weapons, No scarabs, no biology. They would probably just strengthen their already existent ability to eat metal. And that Scarab plague-Emperor-they would be royally fucked. If the Necrodermis entered the hive fleet, they would have to fight an even deeper war with Super AI on a microscopic level. What a clusterfuck of horror who knows what abilities those little scarabs have in the billions? All this ignoring the fact that Necron weapon rip the target’s atomic bonds apart leaving literally nothing for the Nids to recycle. If a Necron guass turret or huge fun got a shot off on a Tyranid ship and successfully zapped it-their instantly in the negative on Biomass.
If Ferrus Manus can integrate necrodermis to himself accidentally, the Tyranids can learn to do so. Necrodermis reinforced Tyranids are a terrifying concept.
I would think the necrons would have a "FUCK YOU!!!" weapon, should they loose. Maybe something psychic, that would affect the hivemind. I doubt the necrons are gonna be easy to take.
I thought we now know that the Tyranids were created by the Old Ones to be their ultimate creation. By that logic, we would think that the Tyranids would be made with the ability to kill the servants of the C'tan.
Well, near immune is true. Recently, Papa Nurgle's boys whopped up a special brew that's kind of like Chaos Super Rust. One that even renders their self-repair systems defunct.
The 40k version of "Will it blend?"
That is the question!
Necron dust, don't breathe this.
I don't see why a "consumed" necron, couldn't be used as a carapace.

They aren't highly instinct based. That's just what the biologis think.
You're mistaking the individual 'nid with the Hivemind and every 'nid is a cell in the Hiveminds body. And it's more than just instinct.
"We're made of star stuff" - Carl Sagan
All things in the universe are made from the same particles, reconfigured and resorted to be shaped into the building blocks of matter. If the Tyranids are able to 'break down and use' other matter beyond that of what has been dubbed 'biomass' for ease of lore and concept in a setting that changes with the stroke of a writers keyboard with every codex or novel release, there would be nothing left of any star system the swarm passes, and their fleets would be entirely unstoppable after a single solar system, the total mass of its star and what orbits its gravity feed to put it beyond the scale of entire segmentum fleets.
Instead they only consume the 'organic' surface and atmosphere of planet that had been one of the lucky fraction to create 'life' in any form, which is well below a single 1% of its total mass, making the overall gains to the 'nids on the grand scale rather limited and even easily calculable with some quick math of how much they could possible add to their collective biomass from our galaxy, or the closest number of galaxies to us.
Therefore, if we go and say the nids can both eat and gain something from living metal, we would have to also let them eat worlds from crust to core, drink gas giants, and more than likely nom stars, which would make them beyond powerful and tip the balance of the lore.
It is my belief then that the tyranids gain nothing other than nano-machine food poising if they consume living metal, unable to adapt to as a cellar level war goes unseen within a hive ship/ripper's guts. and any non-organic materials they devour remain inert and eventually are ejected from the creature that ate it at a later time, perhaps rendered down into slag by bio-acids, or just little more than carbon.
Its 5am. Why must you do this to us?
Now the real question is there a way to make the Nids taste like crabs or shrimp. So my hungry guardsmen will be happy to see them on the battlefield. As a feast in the making.
They're fine to eat as long as you cook them through all the way.
Does make one wonder what the various xenos would taste like?
They will never taste good if the Sisters of Battle get to the battlefield. They will overcook everything.
@@poodlescone9700 your comment just won the day.

Necrons are crunchy with a sour middle.
That is what the C'tan said.
I thought the middle would be salty!
I like how it's just assumed the Necrons would just lie down and take it as opposed to bathing the nids in green light and making them go away.
Nobody assumed that. It sounds like you're assuming the 'Crons would win every engagement so thoroughly that no 'Nid ever got the chance.
Adeptus Notificatus, *REPRESENT*
*SIR YES SIR*
I'll have to remember this
how do Tyranids devour the Atmosphere? like do they stand around and just open and close their mouths?
The hive ships gulp it down
I prefer his theory more
40K Theories they also sook up a planet’s core with a big biomechanical straw too- must be the hottest bowl of soup around Xx
I think necrodermis is made of nanobots. The tyrannids can't eat necrons for the same reason you can't chew and swallow a watch, and then crap out a fully functional watch.
'nids aren't humans. Even on earth there are organisms that can in fact eat metal.
As for the nanobot issue: So are 'nids. The smallest Tyranids are Phagecells, which are a in between of virus and bacteria. The power of the Necron nanomachinery lies in its reaction speed. However Tyranid organisms have been shown to adapt to even the life Eater virus or Nurgles plagues. At least the former requires near instantaneous reaction speed. The Necron Nanobots take longer to do their thing, as the case with the kroot shows.
I think this is a matter of scale, the word nano is far beyond most organic systems. If a entity is a few nanometers. It will be so small that it can pass through cell membranes freely. Viruses and bacteria are huge in comparison.
It's obvious that Warhammer 40k exists on the premise of eternal war for the sake of keeping the table top game alive, alongside the inevitable power creep to keep people from getting bored over time.
So it is somewhat inevitable that tyranids, a race designed around this concept, would eventually evolve to devour what makes them stronger.
What interests me most is not how hopeless it sounds when solely describing war with tyranids, but also the power creep of other factions against them, one of your other videos describes the counter threat of the divine emperor deity rivaling the power of chaos, along with gork and mork, and likely even the hive fleets, because it indicates perpetual stalemate despite power creep.
I would be very interested to know if the hive fleets are running from something worse in their own galaxy, or about the force that drives the norn queens.
If a man can eat an airplane, a Tyranid can eat a metal man.
Eric Grieve maybe that man can eat the tyranids. He is our saviour
I was about to go to bed, but then I saw you posted and decided that sleep is for the heretics!
I've always assumed that necrodermis is either entirely or mostly made of nanoscarabs, similar to the humaniform or Pegasus replicators from Stargate.
I find the kroot story kind of contradicting. How could kroot eat necrons if the all phase out if damaged beyond field repair?
And since when do they eat metal in the first place. The nanoscarab plague is a logical consequence.
I would think the with the genes of the ferrobeast they found a way to make bionical material out of metal. Otherwise, didn't the ferrobeast already have a metal skin?
That whole “Terra is a tomb world” thing just became even more upsetting
Would now be bad time to mention that Genestealer Cult that appeared upon the Throneworld?
*hyperventilates in High Gothic*
I'm a big fan of Arch's theory regarding the Tyranids - that they're another creation of the Old Ones, originally intended to collect the organic essence of all life and store it for after the Necrons died off or went to sleep. Problem is, like with the Krork, the Old Ones had no concept of control or an off switch.
My doctor said I need more iron in my diet. Maybe the bugs need some too
I feel the need to ask Species 8472 to go complete exterminatus against the Tyranids.
Now that would be a fight...
Oh yeah, just hand the tyranid genetic material of species 8472 and make them even more powerful! Once they had it, and they could expend 50 ships to capture just 1, they would have no serious weaknesses anymore.
Of course as a tyranid fan, I have no problem with this! The hive fleets shall consume!
@@evilspoon5280 It is worse than that - Fluidic Space is canonically an organic matrix the size of an entire universe. The Tyranids would be floating in a universe-sized bath of biomass. They would soon evolve vast fleets of Hiveships adapted to hoover it up in incredible quantities, and by the time they travelled (with Species 8472 genetics as a bonus) to other realities their numbers would be even more insane.
@@gregorygreenwood-nimmo4954
Tell me about it! An entire dimension that rich in biomass would be insane to let the tyranids into. Their ships would be so numerous they would blot out the stars across entire galaxies!
Of course as a tyranid fan, I am not against this! The hive shall consume!
I like all your vids. But this one is above all your others. Just because you showed the wasp to back up a theory.
(Fantasy thing set the far future. Here's a real life example.)
Brilliant
The nekrons fought using what can pretty much be described as the absolute pinnacle of what technology can be, without reliance on the warp atleast
while the actual components of nekrodermis is still ultimately just atoms and chemical bonds, more than capable of being broken down, I still consider it beyond plausible that the Tyranids would actually be capable of integrating the material in its original way, unless of course, that whatever controls the hivemind, has an intelligence that can rival the combined knowledge of both the entire nekron race and the C'than. Without the ability to reverse engineer it or understand it, it seems pretty much impossible for the tyranids to incorporate fully functional nekrodermis at all (beyond using scraps as cheap expendable armor, as opposed to a grown carapace of the stuff)
Even if the Tyranids could consume the living metal of the necrons, couldn't the necrons just reabsorb that metal back?
Haha this was the theme behind my last color scheme on my tyranid kill team. A small hive of warriors that consumed an old necron planet. Glad to see some more theory I can use as backstory now
Like any sane fan of warhammer 40k I’d just like to say, thank the God Emperor that none of this is real.
This *IS* the future of the universe...
I wish it was real
For all we know it is real and we're just a lost colony, claiming to be the home world of human race!
Wow. No one got it.
How do you no its not and this isn't the inquisitions way of keeping us in the dark by letting us all believe it's just a made up universe based on a board game.
That's a cool use of a real world example
I just love the irony of both necrodermis and living metal being used to describe the same material.
We discovery channel now. I was not looking at the screen when you were talking about the wasp and was like "Yeah that is something from the 40k univer... Woah.. That's on my current home planet.."
Now I want to model a Hive Tyrant with a necron orb and gaunts with gauss rifles. I have 30 shots from this squad and they get back up after you kill them. They a supported by my new shiny Carnifex who is also unkillable and would get back up even if you tried.
Wait... those wasps are real?! EXTERMINATINATUS! NOW! BEFORE IT’S TOO LATE!
The tyranid will consume all!
They are not even the worst... not by a long way. Nature throws stuff out that is at least as nasty as Tyrannids in its own way... not as all consuming perhaps, but just as horrifying. At least to our sensebilities
*H o l y f i r e t i m e*
The Imperium be like: "Let them fight!"
And what would happen if some Tyranids consumed some Flayed Ones and came down with a case of the flayer virus?
That is not a termagaunt over there it is you Imperial governor. No he is not going to eat your face and flay you alive what ever gave you that idea?
Great work on this.
You ever chew on tin foil with fillings in your teeth?
It would be like sucking apple sourz out of a condenser microphone
I don’t even want to think about what kind of monstrosity nonsense the Tyranids could spawn when evolving after eating Necrons... *Shudders*
I do. Imagine a Carnifex on one of those floating scarab things complete with a Gauss cannon. Actually thats all Iv'e got right now. The necrons are mostly metal skeletons, scarabs and gauss rifles, maybe a few vehicles but those are irrelevant.
Imagine a nanoscarab plague adapting to the Tyranids adapting. Eventually it will end up in a Grey Goo scenario
Awesome video!
Great vid, would love to see a Bio Titan that had eaten a few transcendant C'tan
when the silent king returns, you know things are bad, very bad.
The Tyranids could never steal necrodermis without being stolen by a certain necron whom likes adding things to his collection.
Hello 40k theories (and anyone ells reading this). I am not to knowledgeable about the 40k universe but I recently read about some speculations about how the Death Korp of Krieg are able to replenish their numbers so quickly and one of the suggestions was cloning. This hypotysis was quickly shot down however when people pointet out how humans not naturaly prodused are more subsetable to the warp as the child lacks the natural protection provided by the mother during the pregnancy.
This made me imedietly think about the primarchs and how they were not naturaly born but rather grown in, and i quot "gestation capsule".
So could this mean that from the very start that the primarchs were inherently less resistant to the warp?
The primarchs were still far and above normal humans, so that theory doesn't hold as much weight. As well, the primarchs rebelling had more to do with their beef against the Emporer than chaos, with only hours and lorgar being truly corrupted for the most part
Very true. I have not read any of the Horus Heresy books so I don't know how all the traitor primarchs changed sides and thier reasones for doing so and my knowledge of the rest 40k universe is very limited so I can be very much in the wrong. I was merely making a suggestion that even as the sons of the emperor, it might have helped the chaos gods in some small way to get the primarchs on their side if the were cloned rather than born. Maybe influencing them to overlook certain details and things like that.
Well now my idea is toast... no more tyranid immunity
What a coincidence! I was just wondering about this earlier today. And also what, if anything the Tyranids could gain from doing so.
9:00 AM:How to lure tyranids and necrons into the eye of terror
10:00 AM:How to kill Chaos tyranids covered in living metal
Galactus: These are the pests that keep raiding my gardens!
As well as the wasp there are deep sea, sea snails that use metals in the growth and construction of their shells and have essentially metal shells because of it.
It's an interesting theory. The only problem is that the new Necrons Codex specifically says that some of the Dynastys have taken to returning to Necron worlds after the hive fleets have passed by to gather all damaged and destroyed Necrons to either repair or breakdown their remains for future use. Nowhere in that does it suggest that the Tyranids are somehow absorbing the Necrons living metal. An interesting idea though for sure. =)
Some Necrons want fleshy bodies again, its a possibly this faction may want to create a Necron/Tyranid hybrid body to jump to.
Necrodermis is living metal
icestar750 Ironic considering it means "dead skin".
I wonder how the Flayer Virus would play on the Tyranids. During an Only War campaign I played around with the idea, and can be vicious.
* tyranid sniffs necron world * ugggh too much effort...lets go eat some imp guards
Tyranids are basically the Borg of 40k (consume evolve adapt move on in a hive). They COULD however adapt to consume living metal much like they adapted to fight creatures of the warp
They hate their Cyberdongs. They clog up their digestive system.
Dont forget in 'Storm of Iron' a hive ship was infected with the Chaos Oblitorator Virus as a transport vessell, so if they have eaten a few of them aswell as the Necrons... carnage will ensue
It would be interesting if the hive fleet intelligence could understand how to use faith like how the Orks and Humans have. It might make troops similar to genestealers but focus on worship of the hive fleets, shadow in the warp, specific units, or all the above.
I think it is without question the necrons are the most powerful threat the Galaxy has ever faced however their lack of aggressiveness leaves something to be desired
The fact about the wasp is a very interesting. A little real life.
I wonder how Tyranids taste like...🤔
Tyranids probally leave Necrons alone as fighting Necrons is going be a net lose for the Tyranids
Can you do a "what are the tyranids fleeing from" video
For reals
Probably the missing 2 primarchs. "Eh.. can't really use you guys in my great crusade... here, take this webway to the next galaxy over and see what you can find".
They aren't fleeing from anything. The epilogue of the Horus Heresy novel Pharos clearly explains why the Tyranids are coming :)
Sorry to disappoint you.
Regarding the beacon thing attracting the nids here. It doesn't fully rule out them fleeing something. Could be they randomly fled in terror and later the beacon indicated a good place to head to. Not read the book however so sorry if this is explicitly ruled out.
@@40KTheories I believe that when the zoats were still around the suggestion was that the tyranids were fleeing something.
Wait... the silent king returned? When was this?
The scariest possibility is if the tyranids manage to devour a perpetual
Whether or not they can do it, I'm sure the Tyrandis will give it their best college try once squishier food sources are exhausted, and if I had to bet, I think the infamously adaptable bugs would find a way sooner or later.
3rd ed Tyranid codex makes reference to 'magma borer' creatures thought to be variant of the Carnifex. Upon planetfall they burrow deeper and deeper until they release any deep magma for absorption. If they can absorb that......most elemental metals should not be difficult certain alloys may pose issues but long story short.......WE REQUIRE MORE MINERALS.
Considering how the Necron don’t have any fleshy bits. I don’t think they can be “consumed”.
There are marine snails and worms that can drill their way through solid granite. There are other organisms that can literally dissolve rock, still others that can break down metals, including some that actually thrive on heavy metals most organisms would find lethal, such as Arsenic (yes, it IS a metal). There are others that can survive in heat and acidity that would instananeously kill most other living organisms, there are others, such as tartigrades, that have literally survived exposure to space, and survived well enough to breed afterwards, despite the massive radiation damage an unprotected organism would suffer from such exposure.
I would not find it beyong the realms of possibility for the Tyrannids to in fact be able to do exactly that, as that is what they were *designed* to do. Just looking at Earth you will find organisms that survive in conditions that are frankly mind boggling, what other forms of extremophiles have the Tyrranids encountered. They have already consumed an entire Galaxy remember, an entire Galaxy worth of Genetic material they can work with.... That is even BEFORE they got started on this one....
They have already got ship sized bio weapons that can literally dissolve the ships of other races with streams of bio acids, that right there is consuming, that is basically EXACTLY what our digestive system does. We do not directly use ANYTHING we eat, what we eat is broken up into its constituent pieces, sugers into glucose, proteins into short amino acids, other compounds or elements into whatever form is most easily utilised. The body then uses those building blocks to build what it needs from them. It does not take a hunk of meat and attach it to your own muscles, it breaks that meat down into its constituent molecules, then uses those to build extra muscle if you are working out, or as you grow, or as old muscle simply dies and needs replacing.
Consuming a Necron would be the same process, break it down into its constituent molecules, then siphon them up and use those molecules to create what the Tyrannids need.
@@alganhar1 problem is tho would it even be worth trying to eat a tomb world? The weapons of the crons tend to make things disappear rather well so to start the dead would be nearly useless to recycle as there adoms are blown apart
Some spiders today also have metal in their fangs
Give them time and they'll start eating the warp imagine that endless source of energy and bio mass in the form of demons
how do they fare against gauss weapons ?
If given enough time then yes, I think the Tyranids could start to consume in part or whole Necrons. The more important question is, "What is that timetable?".
there should be a "Warhammerest things in real life" documentary
One thing I would wanna no is could the flayer virus be transmitted to the nids if they attempted to eat a necron flayed one would it evolve to suit the nids n somehow find a way to effect them via there psychic connection to each other.
Good to know. Damned necrons are always cutting through my yard, so maybe I’ll keep a tyranid on a long chain when I’m not home. STAY OFF MY GRASS YOU DAMNED NECRONS!
I am really scared/excited for the future of warhammer lore. Cause it is been escalating lately.. so many worlds consumed,craft worlds destroyed, the appearance of primarks and a eldar God of death
Tyranid size Borg...great fun.
Metal in living things is normal, Calcium is a metal and your skeleton is made of it.
What About Tau....Although I doubt is there any useful Trait Tyranids can get from them anyway.
chen li eating tau makes them communist
But Didn't Tryanid already got that Every Individual Work For the Greater Purpose Part?
May be They will learn How Ethereal Class manipulate their subjects?
Tyranids driving mechs?
May be Gene Stiller could use a Battle suit?
A Tau Genestealer Cult with a rather more... fleshy notion of the 'Greater Good' sounds like a project just waiting to be explored @chen li.
Do you think something like the blacklight virus from prototype, could be a danger or a boon to the tyranid race? Also do you think someone like Alex Mercer or James Heller would be like a straight up hard counter to tyranids?
Considering the amount of metals in mankind (calcium, iron, even minute traces of gold) I don't see why not.
Of all the forces extant in the galaxy, it feels like only the Tyranids can present an equal opposition to the Necrons, and vice versa. If it ever happened, it would be a sequel to the War in Heaven; the Wars of Hell.
Been wondering about this for a while now. Thanks for covering. Could a hive fleet devour and absorb Necron traits? Scary thought. Could they possibly do the same to a C'tan shard? Terrifying thought.
S Blair ctans are pure energy tho could the tyranids gain anything from that besides caffeine?
I really just don't know. The way tyranids adapt could, I suppose, make about anything at least possible. If it ever did occur though I'd truly fear what the result would be.
S Blair or maybe the tyranids would serve as a screening force for the outsider/hive mind? We know Ctan can eat other ctan after all, and it seems quietly confirmed he’s behind the nid hive mind. Nd he was the only ctan to not be shattered. Friend, I think you shouldn’t fear the Nids being able to consume ctan, but rather the outsider eating ctan.
I guess time will tell. Neither sounds nice though because either way, the galaxy would be done for imo. I mean, what's out there that would stop that?
Isn't the arms of Ferris Manus coated in necrodermis? So that may be another good example of integration with a living organism.
You know like how chaos rhinos can have living victims grafted onto the hull.
I imagine a tyrant carapace with necron limbs protruding from it.
Still living but unable to be recalled due to the shadow in the void, there broken body's have been fused into the tryanid carapace, ever trying to rebuild them self inside, giving the carapace the characteristics of living metal.
The carapace move around as if people were trapped inside, trying to get out.
Do the tyranids consume the metal elements of a planet?
If so, does that include the molten metal cores of planets?
Turanids avoid at all costs The Necron World's,it was in One Book that I read,bat I can't remember which one, Great Work as always 😎.
In the earlier codexes they seemed to maneuver around cryptworlds, however the story has since progressed.
Kaza ddum did they ever get around to successfully incorporating Necrons metal? I don’t know I’m just curious.
I think...even if they did it wouldn’t be much worth. Here’s why,
The reason (as I understand it) that Necrodermis is so good is because it’s not just metal, but “living metal” that operates within the Necron firmware and abilities: warping, electric exotic energy blasts, tiny scarabs that work as super AI but in the microscopic billions-which is why the living metal regenerates so quickly, because it’s essentially a billion billion little super AI workers-much better and more powerful than typical or even Tyranid cells. The tyranids wouldn’t even gain the exotic matter guns that the Necrons use. The Nids would walk away from the engagement with just more metal. No guns, No new weapons, No scarabs, no biology. They would probably just strengthen their already existent ability to eat metal.
And that Scarab plague-Emperor-they would be royally fucked. If the Necrodermis entered the hive fleet, they would have to fight an even deeper war with Super AI on a microscopic level. What a clusterfuck of horror who knows what abilities those little scarabs have in the billions?
All this ignoring the fact that Necron weapon rip the target’s atomic bonds apart leaving literally nothing for the Nids to recycle. If a Necron guass turret or huge fun got a shot off on a Tyranid ship and successfully zapped it-their instantly in the negative on Biomass.
The Old Ones probably programmed them to avoid Necron worlds as that would provide the C'tan with the life that they wanted.
If Ferrus Manus can integrate necrodermis to himself accidentally, the Tyranids can learn to do so. Necrodermis reinforced Tyranids are a terrifying concept.
I would think the necrons would have a "FUCK YOU!!!" weapon, should they loose. Maybe something psychic, that would affect the hivemind. I doubt the necrons are gonna be easy to take.
They have a super weapon that will cause stars to go supernova all at once
I thought we now know that the Tyranids were created by the Old Ones to be their ultimate creation. By that logic, we would think that the Tyranids would be made with the ability to kill the servants of the C'tan.
It would be a long and devastating war but tyranids have something necrons dont: the ability to replenish their numbers
Ahh the Necrons, near immune to Chaos, Tyrandis, Hacking, Time, Death and the greatest killer of all... Boredom.
Well, near immune is true. Recently, Papa Nurgle's boys whopped up a special brew that's kind of like Chaos Super Rust. One that even renders their self-repair systems defunct.
If a fleet ingests necrodermis on a large scale could the said nano metal act like the Tau bio weapon but activate and tear apart the fleet
