All Primarch Gene Seed Flaws in Warhammer 40K 

"As space wolves grow older, their hair will turn grey" That happens to most people I think.

What do you mean Vulkan *WAS?* he still is. *VULKAN LIVES!!!* Stomp stomp!

- *Fulgrim:* penchant towards narcissism and perfectionism - *Perturabo:* extreme paranoia - *Jaghatai Khan:* susceptible to berserker rage - *Lemann Russ:* have wolf characteristics and may devolve into wolf-like beasts during their ascension into Astartes or during their lives - *Rogal Dorn:* no defect, one successor chapter's astartes suffer from catatonia - *Conrad Kurze:* intrinsic pessimism; Librarians are susceptible to seizures when they have visions; physical pallor and dark eyes - *Sanguinius:* the primarch had angel-like wings; Astartes are susceptible to a blood-thirst; Astartes are susceptible to berserker rage - *Ferrus Manus:* primarch had his hands covered with necrodermis due to accident; Astartes suffer from body dysphoria and self-deprecation - *Angron:* Primarch and Astartes are routinely implanted devices that increase battle performance while leaving them susceptible to corruption; innately gregarious but with a penchant towards bloodlust - *Mortarion:* Pale and gaunt; resistance to contagion and toxins (actually an advantage?) - *Magnus the Red:* red skin, extreme psychic power; Astartes have a high sensitivity to the Warp, sometimes manifesting in possession into Chaos Spawn - *Lorgar:* theophilia, has a need to worship someone or something; high warp sensitivity - *Vulkan:* physically strong, even for a Primarch; red eyes, coal black, heat resistant skin; high physical resilience; stubbornness; - *Corvus Korax:* albino pale skin, black hair and black irises; Astartes lack of Mucranoid Gland and Betcher's Gland; Astartes susceptible to melancholy, narcissism and pessimism - *Alpharius and Omegon:* high implantation success; - *Roboute Guilliman:* no flaws, Primarch shows high resilience to corruption - *Lion El'Jonson:* no flaws - *Horus Lupercal:* no flaws, considered to be physically and mentally superior to other Primarchs, later found out to be extremely naive towards the warp and susceptible to corruption

“Leman russ, also know as the woof king and primarch of the space woofs”

Magnus is a nerd, vulkan just too damn nice, rogal dorn is brutally honest, leman russ has a wolf fetish, perturabo is childish, fulgrim is always trying to beat the emperor in getting majestic hair

Silly heretic, the emperors work has no flaws, only “features”

Ravenguard be like "It's not a phase mom, it's my geneseed!"

Ferrus Manus had arms covered in Necrodermis, not prosthetic replacements.

@onemindsyndicate vestigal means left over, non-functional. Sanguinious 's wings were very much functional.

The one that guilliman passed on was being the space marine equivalent of that kid that tries too hard to be valedictorian

Are you sure it was a "Genetic Flaw" that made the Iron Warriors hate the rest of the legions? Not the fact they were treated like trash by literally EVERYONE? Including dear old dad?

Vulcan for the win, Salamanders need a codex. "Into the fires of battle, unto the Anvil of War!" Great job getting to 100k, where's that RU-vid play button going to go?

"Leman Russ, also known as the Woof King and the Great Woof"??!!!?

Alpha legion flaw: Everyone is Alpharius.

“And I probably didn't include a third primarch probably...maybe?” Horus: rolls in his grave.

The Salamander's flaw wasn't their skin changing. It was just their eyes. The skin change was a result of their station upon Nocturne making their defense against the environment kick into overdrive like Vulcan's did.

You missed Horus Lupercal! The Warmaster, the Great Traitor!

Blood Angels will occasionally develop small wings during their transformation, these wings are removed.

haha the spirit of the woof

There's a theory the black Templar have a flaw that they feel dorn's rage when he chased chaos after the Horus heresy

I have a theory that one of the forgotten primarchs was a blank, as it is indicated that at least one primarch was expunged due to some genetic defect, and a blank is basically the only major mutation not accounted for within the primarchs.

I absolutely love your channel and the lore, every second of it. THANK YOU for creating these videos! For the glory of the Emperor!

From what I understand the Dark Angels, Ultramarines and Grey Knights are the only chapters with “Pure” untainted geneseed.

"Rowboat Girlyman was super perfect and any flaws totally weren't his fault." I know who's narrating this video, his name rhymes with "Matt Ward"

I always thought Sanguinius' Wings were functional and not vestigial, maybe check that... Also, I love how cheesy Corvus Corax and the raven guard are with all their existential drama. They're up there in goofyness with the Space Wolves and their canine fixation. It's just too much, I can't take them seriously. Every time I remember the moment of Corax flying away into oblivion shouting "NEVERMOOOOREEeeeee..." I can't help laughing. That said, I wouldn't change it a bit. I think those silly details in a setting as grim as 40K make the whole thing much more entertaining.

honestly , the emperor , the primarch and the legions they command look like vampire the masquerade clans to me

Onemindsydicates gene flaw is the inability to consistently pronounce the word wolf constantly switching to woof then back to wolf. His children have seemed to have carried on this flaw and struggle to read the three little pigs and little red riding hood.

you are the reason i know so much lore thanks for all the hard work

This episode got me thinking, It seems like they have a lot in common or in contrast. I'm sure you could organise this another 10 different ways but here is what I noticed. Death Guard v Salamander = Resistance World Eaters v Blood Angels = Anger Black Legion v Ultramarines = Genericness/Size Iron Warriors v Iron Hands = Robo fetish Word Bearers v Dark Angels = Religiousness Night Lords v Raven Guard = Egde Alpha Legion v Imperial Fists = Tactics Thousand sons v White Scars = Taking your homeworld to heart Emperors Children v Space Wolves = Unflawed vs Flawed from the start

Had me going you guys Rock I swear sometimes it feels like you guys are just my buddies giving me info about the lore as we sit around and talk.

I do have to say though that the angels wings are not vestigial as they function, are completely advantageous and are a new mutation not a "vestige" of the species he evolved from.

Amazing videos. Absolutely awesome to listen to on my long drive to work. It also saves me time from having to tell my wife (who is using some parts of lores as ideas to write a current book) the lores and stories of questions she has.

So, where did Abbadon inherit the genetic flaw of having no arms?

Great video I like the longer more broader videos like this that cover a very wide variety of lore and I feel like that really catches the interest of new comers who will then want to find out more for themselves.

16:25 wait a god damn second. Say that again. Salamanders only darken due to heavy radiation? So hypothetically I could make am Axolotl chapter, write lore that they are a successor group, stick them in a low radiation zone or like under ground and they'd be white as Scandinavians? Thinking like a kinda white / light pearl color scheme.

Love this channel, listen to it every morning going into work in Alaska! Hope to keep hearing some great lore and 40 facts and maybe win a box set some day. Keep up the work!

Doesn't the Emperor's Children have the blight? The genetic flaw that nearly wiped them out and prompted Fabius to study genetics?

Roboto Gorillaman, as always, is perfect and never does anything wrong. Nice one, GW!

Some call them flaws, but I believe the emperor was trying to create beings to challenge him in all aspects of his life so that he would have someone help him grow so he would not stagnate.

Well done for hitting 100k what a milestone.

One possible reason for the later ultramarine flaws is they 'adopted' loyalist elements of the trators

Love your guys content. And I've been wanting to get that starter box. I would also like to thank you listening to your lore videos in December of 2015 got me to start playing 40k. You would always stop and say I hope your painting is going well. Do finally i went online and bought assault on black reach. From there it took 5 months to get my first game but I love it. Thank you guys for getting me into the greatest hobby ever.

Heresy! There are NO flaws!🔪💀

This is my favorite lore channel.

You are wrong on a lot of these! The Wolves ALL have yellow, black pinned eyes and they don't get leathery skin, they get pale and translucent skin with age, just like Longfang in Prospero Burns. The Fists don't have acid spit. The Emperor's Children have a compulsion to vanity. The Iron Warriors are morose, have terrible tempers, and will not relent, even when it is victory to do so. The Iron Hands have more resilient flesh as well, this was indicated as Erebus was trying to sacrifice them. The Death Guard are resilient and enduring. The Thousand Sons have the flesh change. The Blood Angels have the red thirst. The World Eaters were blood thirsty beyond advantage or reason. The Word Bearers didn't really have any overt flaws, only having an inclination to faith. The Salamanders had burned skin and red, glowing eyes, the Salamanders' natural state was viscous commitment and self destruction. This was solved by Vulkan's tempering of his sons. This is well outlined in Old Earth. The Alpha Legion is not only secretive and deceptive, but is prone to over-complication. The three you didn't list were Horus, Guilliman, and Jonson. These three had remarkably pure gene seed, particularly the 1st and 13th Legions. Before then Rangdan Xenocide, the 1st Legion was the largest legion by a large margin. After losing a large percentage of their Legion, they were a close second. You had great information on the 19th though.

Hey if they're bringing back plastic sisters we can all keep secretly hoping for squats to make a comback

One mind Syndicate is my favorite daily RU-vid stop. You guys have really helped me grow the hobby Question: do chainswords idle like a modern chain saw. Or do they spin up in an instant? Like an electric chain saw? Like wise do power/ force weapons make like lightsaber noises? My local group was playing a Deathwatch rpg game and the question came up while “sneaking”

I have always loved the videos on the Primarchs as well as the videos on the fan made armies. In fact, it was the fan made chapters videos that have been inspiring me to further develope the back story of my own chapter in the hopes that they might be the topic of a future video

:D Are they geneseed flaws? Or just happy accidents?

thanks for all the videos , love the 40 facts

guys it's, 2am go to bed

Thanks for the dedication guys.

For the emperor!!

Ive been a big fan of dawn of war games for quite along time and that giveaway would actualy push me into figures

Ave Imperator

HERESY OF GREATES MAGNITUDES!!!! *Fyodor flayling the sword uncontrolably*

Of course the most flawed was ++comment redacted by the holy inquisition++.

Watching these videos makes me want to get models. The lore is amazing. Thanks guys

Omg I'm new to Warhammer and subscribed to your channel cuz I love the lore and I really hope I can win the know no fear set as I'm already planning on getting the first strike set.

I still love all my brothers no matter what. I see no flaws with them. They are perfect in my eyes.

#BlameBigE

There is a good argument that Lion had very strong flaw which was being paranoid. Thats why his sons dont trust eachother at all, make secrets out of everything. Also its interesting story point that both splinter groups consider themselves to be the real Dark Angels and some think that people like Cypher may actually go with the real chapter plan (which is obviously super secret). Fallen Angels are not aware that Chaos is supporting them and messing with them.

The videos you guys put out made me start playing, I have a friend who tried to get me into it but he was never good at explaining the lore

I love, how Guillimane is just Octavian, first emperor of the roman empire, upon a space-marine-body.

i'm just starting warhammer (bought an old "battle for macragge" set) and i was pretty clueless about a lot of the lore. these vids definitely help.

Congrats guys on 100k!!!!

Know it’s a long shot but gonna try to win the starter set, one of my buddies and I started up playing warhammer 40k recently and he chose space marines as his army and I chose chaos for mine winning this would help save a lot of money for both of us. Love the videos and keep up the good work

All interesting. For me I'd have to say the Blood Angels Red Thirst and Black Rage have to be my favorites. Talk about berserker, blood thirsty super humans running at you with no regard for themselves sounds terrifying. Whether fighting against or fighting on the same side. Having to witness that on the battlefield would truly be horrible. Probably for those fighting for the imperium; you would see the emperor's angels of death that resemble humans going crazy to bathe in the enemies blood, that would make anyone go insane.

Congrats on 100k :D

Thanks for your amazing videos !!!

love the lore videos about the primarchs! Keep up the great work!

Keep up the good work guys. I'm listening to you while painting. Thanks!

Your videos rock man! I watch them all the time! Keep doing what you’re doing!

don't forget that Alpharius tampered with the Raven Guards geneseed so that when Coral would try to replenish his ranks almost all of his new Marines ended up with fatal mutations.

The art of Corax at 17:05 always freaks me out everytime I see it. His long hair just flowing in the breeze..... near the active intakes of his jumpack that could suck in his hair at any moment.

Loving the lore and 40k facts, keep up the good work

Dorn’s flaw is unable to understand the funny, and addiction to the magic pain glove

Find it kinda endearing that every time you say "wolf", it invariably comes out sounding as "woof." The "Space Woofs", et al. :)

Thanks for the amazong videos on the lore you put out :)

Love the channel hope to see this content for years to come!

Definitely liking the content. Looking forward to hopefully winning the Primaris Marines! Grew up watching my dad play, and watching my roommate make his own army now.

Essentially the Imperial Fists chapter that had the flaw suffers from a genetic flaw of the ultimate form of depression.

Perturabo: Terminal Emo behavior (see also: Corvus Corax) Roubute Guilliman: Chronic Goody-Two Shoes disorder. Leman Russ: Uncontrollable ball-licking.

pretty sure girlyman's genetic flaw is 1. being a girlyman, 2. being glorious 3. feeling blue all the damn time

I am new the hobbie and thanks to you guys I decided on the space marines chapter to go thanks.

love all your content thanks for all the hard work.

A fairly comprehensive list of the flaws. Keep them coming!

Love the videos as always!

You deserve each and every subscriber you have! Keep the good work. I'm looking forward for what's coming next

They all fade in the glory of Ollanius Pius. The blood Rage, Dorn's darkness, are basically RNA epigenetic jealousness.

Lionel Jonsson passed on paranoia and calculated distrustfullness on to his chapter. So much so that in one novel, a traitor who was being tortured by a Chaplain intimated that the reason the Lion was not present for the battle of Terra was NOT because of the Dark Angels civil war, but because he was waiting to see which side was going to win.

The Imperial Fists don't suffer from genetic degradation but through misadventure have lost the Betcher's Gland and Sus-An Membrane from their suite of gene seed. This has, to my knowledge, been due to those particular implants being lost over time due to battlefield losses leading to lower and lower recovery rates for those glands until they were no longer viable.

Nice video congrats on 100k

Hey guys awesome video! Keep up the amazing work. You guys are awesome!

-What were Horus' flaws? -YES!

when you said 100,000 i thought you were going to say dollars i almost fell of my chairXD

The Primaris support to the chapters is probably the best idea gw could have done.

Suggestion: Primarch ambitions (What did they desire most for themselves and their legion)

Great video. Really enjoyed it cheers.

I saw a documentary that showed the greatest enemy of Roboute Guilliman and the Ultramarines. It’s a Chaos Sorcerer called Gargamel. He has a cat.
