If you want to go the funny rout, 40k isn't touching 22nd century from Doraemon. It's a setting were all civilian have a time machine & a anywhere door(open a portal to anywhere within 10 light years), a flashlight that let you adapt to any environment(the bottom of the ocean, vacuum of space,...)

Goku healing the Emperor and causing the Imperium to collapse is something I didn’t know I needed to hear and now visualize😂

Vegeta worshiping himself so hard he single handedly turns himself into a Chaos God

Superman is NOT weak to magic. He just has no defense against it. He has tanked magic attacks or blasts that could destroy a universe plenty of time before. Also NOT all Superman is "weak" to magic, some versions like Cosmic Armor Superman has NO weaknesses.

I mean in terms of doom series, 40k straight loses to doom's demonic invasion.
They ignore the concept of time, their very fabric of being cement them into a reality causing them to ignore reality weapon and unlike daemon, doom's demon can just teleport anywhere in real space they want without needing warp anchor and their demonic corruption happens far faster and more potent than 40k daemon.

The DC Universe is constantly expanding and is, in fact, infinite in size, as are all the other DC Universes, the Source Wall is a pan dimensional membrane keeping it from dissolving back into The Source

10:44 YES THERE A THREAT!!! in Total War Warhammer 40K one Tau crisis suit is the same as a Space Marine and they have enough of those that not even a couple chapters are able to match sooooooooooo HELL YEAH THERE A THREAT!!!

The markers would be much more of a tzeentch thing than a nurgle thing. They mutate and change much more than infest and corrode.

47:52 this is based on the afaik mistaken assumtion that the final battle of guren lagann was on a galactic scale.
Iirc those things Simon and the anti spiral are throwing at each other aren't galaxies. Those are universes. They look like galaxies because for obvious reasons, the creator of the show didn't know what a universe looks like from the outside at a distance

19:50 The Lantern Corp could definitely take out 40k. Even if we take into account that the DC universe isn’t infinite, it is still far large than the galaxy setting of 40k.

Also, the Lanterns hop between galaxies and all over the universe at a whim thanks to their wormhole/warp doors and the Lanterns themselves can travel at the speed of light. While races in 40k have trouble navigating within their own galaxy. They can also conjure any multitude of weapons, armor, and shields from nothing.

The entire galaxy of 40k all races combined is not touching an entire universe worth of all Lantern Corps combined. Even if you limit it to only the Green Lantern it’s still not close.

Also Superman is not weak no magic he is just vulnerable to it. Meaning you can hurt him but it is not an instant win if a Psyker faces off against him. You also have to be crazy powerful for it to have any type of strong effect against him. The random Psyker or Eldar is not doing any meaningful damage to Superman. He has faced off against people with magic to alter reality and even the physical embodiment of a universe that contains nothing but magic. The only people who could probably hurt him would be Chaos Gods, Big E, Eldar Gods, or C’Tan, Very Proficient Eldar and maybe Magnus.

23:41 I do want to say that when he made this video, that info wasnt known yet in the show

30:25 TO BE FAIR... he did that to himself

Superman isn’t weak to magic, he just doesn’t have any specific resistance to magic. It’s like calling Humans weak to fire when nearly everything is weak to fire. And even then Superman has beaten plenty of magic users like Shazam.

33:42 it has the tiny side effect of detonating every star in the galaxy.

He also has great videos about fitting halo factions into 40k. Those are grsat even if he is a bit biased towards Halo. But as a Halo fan I get it. Even if he uses lore from 343 which I try to ignore.

You're thinking of The Culture series by Iain Banks. And yeah. Culture breaks the backs of every single faction on their knee...simultaneously. Unless the Minds are going toe to toe  aganist a Chaos Gods in the Warp they ain't loosing.

Also the book series Airier was thinking about is probably The Culture by Ian M Banks

Man these videos are so old i super forget if i seen them already, pretty sure i saw this one already on stream but im gonna rewatch this.

36:15 I was just about to make a worm comparison, damn.
People really just don't het that once you leave earth, there are TRILLIONS od Entities, jist chilling in space, and the only tine they killed one was basically assusted suicide that needed a planet's full cooperation.

48:00
Those that's not a  galaxy. Thars a universe.
Each individual galaxy in the backround is a universe.
Simon has declared he is manlier then you, therefor he win
The entire show is just the perpetual fight on the side of hope.
The more you belive, the stronger you become.
