Who are the Real Sons of the Emperor of Mankind? (Warhammer 40K)

Who are the real sons of the emperor? that is a question for the ages, one that might persist for 40 thousand years after this video is posted, upto the 42nd millennium. There are a few, let say types of people that want to hold this title in the grimdark. The custodes or the grey knights or the sensei or the primarchs or leetu? All of them have more or less, equal claims to this privilege, so here in this video we will dive into each of their creations and how close are they to the master of mankind. Although we might not come to a canonical answer, the journey into this topic will at the very least raise a few eyebrows and stiffen a couple of morning woods.

im sure the emperor has busted countless cheeks. In my head cannon i wonder if Valdor is like a grand son or something cause he went WAY out of his way to get him.

Primarchs: “Do you love us Father?”

Emperor: “Oh Sons? I love you all equally. (They leave) it’s you . . . and by lot.” (Hug Kitten)

The emperor is the mightiest of the Nephilim.

I always considered Leetu a prototype Primarch rather than prototype Space Marine, i know he designated as such in canon but if he was created earlier using the same technique as was used on the Primarchs that would lead me to believe he wasn't a human implanted with gene seed but in fact a test tube baby just like the Primarchs. It's not as if we can use his model for scale as it is an ancient model pre first edition, we don't know how powerful he is but if he thinks he could defend Erda from the Emperor he must have some mad skills or be supremely over confident (both?). Maybe he was the most basic Primarch you could get, not tall, not strong, not a psyker, no visions, but possibly a perpetual and/or a blank?

Check Your sources, LE2 (LEETU) was not retconned, as he is prominent haracter in "The End and Death" (2023) novel still being prototype marine.

With the way Valdor was sought after, and how it was so important for Big E to find him, and of course the way he is said to be the third part of the Emperors Imperium, really makes me wonder if Valdor is the actual biological son of the Emperor. He was said to be above every other Custodes. Almost as if he were the "Primarch" of the Custodes. But the way he even views the Primarchs and his interactions with them. Its almost like he is the biological son of Big E, and the Primarchs are Big E's adopted children. But thats all just my personal head cannon.

Guy has been around for so long it's quite likely every single human in 40k is related to him.

[sugargame]

If the Emperor isn't the Primarchs' father then who fertilized Erda's eggs?

[heretech]

Maybe valdor will have been searching for a sensei to fuse the soul of the emperor to become the starchild

[ZeroaofGOD]

Most of you do not understand, the emperor was a being created to be wise from the very get go. He is in all ways above all other humans in mind and wisdom. So i believe his needs are different, someone of his intellect would not truly find another that is on his level therefore he wasnt actively sleeping around. I believe he is a complex being who would much rather focus on goals to help humanity than worry about love let alone sex. No woman would be interesting to him, who could possibly match him or even have conversations about things he would take interest in? He would not just also sleep with some random woman as he is not an average guy that lives and dies and that is that. He had one goal from the start as he himself was created to help humanity or else we would be doomed.so that being think there was ONE woman which we are not yet fully aware of that DID in fact catch his attention and i think its safe to say that it was Constatin Valdor's mother. The emperor of mankind has but ONE biological child and it is Valdor. His ONLY begotten

okay I get thet fact that maybe the sensei aren't canon from a long time, but is Leetoo ? I mean if I remember Erda is still acompagned by a space marines (and some thunder warriors) in a book

or maybe I misunderstand somethings

[WeaponDamage]

Ah yes, Leetu, the true prototype space marine

[alexanderimmortal]

Ooo juicy topic 👅👅, but yea the Custodes are easily the Emperors most favoured toys, above the super emotional primarch babies

[sethozturgut]

The Emperor visits a Fertility Clinic:
Doc: "The Seed are Strong, Mister... Mr. M'Lord‽" 🤨
Big E: "Ah ah ah... Gene-seed..." ☝️
*Sighs* 😮‍💨
Doc: "The 'Gene-seed' are Strong, Mr. M'Lord!" 🙄

The real sons of the emperor are the ones that still buy metal models vs plastic ones

[andrewverrett]

I want to know who the two unknown primarchs are. I want to know so badly. I feel like they were hidden for a reason. Maybe they are the most powerful ones.

[forthencho]

So are u going off the old lore cuz the new lore saying that the Primarch had a mother, she also use her gene to help make them?

[Masonicon]

6:44 more reasons I canon welds 40k Universe that my projects use

[onieyoh]

What if their all his children in their own way, like the adopted stepchild.
