Chapter 5:
Someone once said, if you hate someone, send them to the Warhammer 40K universe.
In the world of Warhammer 40K, crossing over is like stepping into the abyss—every step teeming with mortal peril.
But now, Godzilla was starting to reconsider.
'Maybe getting isekai'd into Warhammer 40K isn't so bad after all,' Godzilla muttered.
[That's only because the big players haven't noticed you yet.]
'The Chaos Gods should've noticed by now.'
[Not quite. The Tyranid shadow in the Warp is interfering with their perception. The Big Golden Guy on the throne, though—that's another story.]
The Golden Throne: a device located in the heart of the Imperial Palace on Holy Terra. It siphons psychic energy and seals the Webway gate hidden beneath it.
Legend holds that during the Horus Heresy, Magnus the Red shattered the wards, unleashing a daemon incursion through the Webway. The Emperor, forced to intervene, sealed the breach—at the cost of being bound to the Throne forever.
From that moment, the Imperium was plunged into millennia of darkness and despair.
That's why no rational soul would ever choose to end up in this universe. But of course, nothing in the galaxy is ever rational.
'The Big Golden Guy won't mess with me. He can't even *if* he wanted to. I'm more worried about the Necrons and the Eldar. Especially a certain collector king—if he sees me, he'll try to freeze me for his trophy room.'
[Yeah, if Trazyn the Infinite finds you, you're absolutely ending up in a stasis vault.]
The Necron dynasties, heirs of a godlike scientific civilization, wield tech that makes human innovation look like cave paintings.
And if anyone could replicate—or *contain*—Godzilla, it'd be them.
But Godzilla's problems were far from theoretical.
Two massive drop pods slammed into the plains nearby—two more Tyranid Titan Tyrants emerged.
Unlike the last one, these two were specialized melee variants.
The Norn Queen had clearly learned from the previous failure—these new monsters were bulkier, bristling with chitin plating.
Their upper arms were gorilla-like with shielded knuckles, while their lower limbs clutched twin Tyrant Swords, their edges serrated for evisceration.
They flanked Godzilla from both sides. He shifted his gaze between them.
'I feel like the Hive Mind's personally coming for me now.'
[Well, they *did* lose a Titan. You haven't forgotten what the Tyranids are good at, have you?]
'Of course not. They adapt. Evolve. Throw biomass at a problem until the problem dies. And all those knife bugs and gun bugs? Useless against me. Titans are their only real threat.'
[Correction: Titans are the only threat on the ground. But you *do* remember they have a certain special unit, right?]
'Special unit...?'
Godzilla blinked. In the distance, a lone Tyranid creature bolted from the battlefield. It wasn't charging him—it was retreating.
'Wait... that's not a coward... that's a *Genestealer*?! That little thief!'
Godzilla remembered what Genestealers were infamous for—collecting genetic samples. They infiltrate, adapt, and transmit DNA back to the Hive Fleet, which then splices it into future strains.
They were living, breathing blueprints.
And this one was about to steal *Godzilla DNA*.
'They haven't gotten my genetic code yet!'
[You sure about that?]
'Damn it!'
Godzilla roared and unleashed his incandescent breath in a white-hot blast, aiming to vaporize the Genestealer and the surrounding swarm.
But the two Titan Tyrants lunged, sandwiching him between them.
The blast narrowly missed the Genestealer, who clung to a flying Gargoyle unit and took off into the sky.
'Why can't I just use atomic breath?!'
Because right now, Godzilla's stuck in his first-gen form. He won't unlock nuclear breath until his second form evolves.
Only incandescent plasma for now.
'Can they really mass-produce *me*?'
[If anyone can, it's the Tyranids.]
'Won't that backfire? Every time someone clones me, it ends in disaster.'
[With the Tyranids, that's... TBD.]
The full horror of 40K was slowly dawning on Godzilla.
These weren't kaiju from his own universe. These were Tyranids—fragments of the Great Devourer, a cosmic hunger so vast it made entire species extinct as an afterthought.
The Genestealer vanished into the clouds.
Godzilla, pinned between the Titans, pushed with all his strength. They countered, locking him in place.
'YOU LITTLE THIEF! GET BACK HERE!'
Meanwhile, the swarm surged. Knife bugs scaled his limbs. Some lunged for his eyes, others wriggled toward his nostrils.
He clenched his eyes shut and incinerated the closest swarm with another burst of heat, but more kept climbing. They began to cover him like ants over prey.
Onboard the Ultramarines flagship, the Space Marines watched in grim awe.
"Emperor preserve us... those Tyranids won't let him go."
"He's xenos, yes... but the way he fights—it's almost noble."
"Doesn't matter. Two Titan-class beasts? There's nothing we can do."
They'd seen this story too many times before.
A lone defender, a hopeless stand, a tragic end.
They couldn't help. All they could do was witness.
But then—
'I'm gonna beat the Hive Mind's face in so hard it forgets how to chew!'
[Do you want to activate the "Godzilla Full-Form Experience Card (1 Hour)"?]
'Yes! Let's do this! I want the Hive Mind to *run* when it hears my name!'
[Confirmed. Experience activated. Try not to explode the universe.]
Suddenly—
**BOOM!**
The explosion wasn't just sound—it was a *statement*.
A primordial roar echoed across the battlefield as Godzilla unleashed his full might.
Not just first generation—this was *all* of them.
Heisei. Millennium. Shin. Singular Point. Monsterverse.
The transformation ripped outward in a shockwave of raw force.
Everything near him disintegrated—the sea of swarm creatures turned to dust.
The two Titan Tyrants?
Shredded. Torn limb from limb.
Their grotesque remains fell with a sickening *crunch* to the blood-soaked earth.
The battlefield fell silent.
Smoke rose. Blood sizzled.
And Godzilla stood alone, burning with power.
To the Space Marines, he was no longer a monster.
He was a *force of nature*.
A living apocalypse in reptilian form.
And somewhere, in the cold hunger beyond the stars—
The Great Devourer finally took notice.
