Transformed into Cosmic Horror in a Sci-Fi Universe

After Eugene and his party safely crossed from Sector B to Sector C and headed towards the Meias planetary system, I felt relieved.

Suddenly, someone came to find me.

[Was it you who destroyed my creation?]

[…?]

It had a terrifying appearance, like an amoeba enlarged to the size of Jupiter.

I could identify it through information from other universes.

‘Ubbo-Sathla.’

A colossal unicellular organism, referred to as the origin of all life… an Outer God considered a creator deity that literally created life.

Naturally, it was a top-tier Outer God like Nyarlathotep.

It had countless creations, akin to avatars, spread across various universes, with the number of its creations being the highest among Outer Gods.

It was said that nearly quadrillions of its creations were active across the universe.

Well… that’s just what the literature from other universes says, so the exact number is probably uncountable.

But to say I destroyed one of its creations…

What is it talking about? The only life form I recently destroyed was that giant monster… oh.

[It was a work I painstakingly created. And you destroyed it. Are you trying to hinder me?]

Ubbo-Sathla seemed quite angry.

Apparently, it was upset because I had effortlessly killed the giant monster it had meticulously crafted.

…I didn’t mean to; that thing threatened my avatar first.

Well, it didn’t actually threaten, but it felt like it might.

I didn’t know it was something you created.

[My apologies. I didn’t know it was your creation.]

In situations like this, an apology is the best course of action.

No need to escalate into a troublesome conflict.

[Don’t think you can get away with such a petty excuse. How dare you destroy my… hmm?]

But then, Ubbo-Sathla seemed to notice something and looked behind me.

Oh, right. I had materialized Eugene’s perspective into a screen to watch like a drama.

But this is something other Outer Gods can easily do, so why would it be interested…

[That Tera life form, is that your creation?]

Huh? Oh.

It’s not the screen but Eugene inside it that’s caught its interest.

Well… considering I imbued it with personality, it’s fair to say it’s my creation.

[Yes. Is there a problem?]

Why is it suddenly interested in this?

Surely it’s not going to claim that creating life is its exclusive domain and start some ridiculous territorial dispute…

[Very intriguing…! Compared to the giant monster I created, this is far more fascinating. Though it’s currently weak, it has the potential to grow and even kill giant monsters.]

Saying this, it suddenly moved closer.

Ugh…! Don’t shove that slimy, sticky body at me…!!

Of course, I also have a terrifying, wriggly, and sticky appearance, but I still feel a sense of repulsion.

Why do Outer Gods all have to look so grotesque and creepy?

Trying to avoid contact, I subtly moved away, but it leaned in even more, almost entering the screen as it stared intently.

…Is it really that fascinating?

It’s just a typical overpowered protagonist from another world, isn’t it…?

[A creature designed to start as a lowly being and eventually overpower formidable creations… very intriguing. This might help me achieve what I desire.]

With that, Ubbo-Sathla turned its gaze back to me.

[I will forgive you for ruining my creation. Instead, I would like you to cooperate with my plan.]

[Plan?]

Hmm… What is this?

I have a strong feeling that I’m about to get involved in something extremely troublesome.

Ubbo-Sathla.

An Outer God referred to as the origin of all life in the universe.

He created countless creatures to the extent that he earned such a title.

According to some universe’s scriptures that worship him, his offspring spread across the universe number in the quadrillions.

Of course, even that is just an estimate from their scriptures.

In reality, the number of his creations spread across the multiverse is uncountable.

For reference, in the sci-fi universe I was born in, there are numerous creations of Ubbo-Sathla.

Many giant monsters, including the one I destroyed, and even some of the species within the Galactic Union that almost dominate the current universe, are actually his creations, not naturally born.

Even the Lubaran race was a civilization directly created by Ubbo-Sathla.

The reason Ubbo-Sathla spread so many creations across various universes is simple.

It was to absorb the life forms living in those universes as nutrients.

[To achieve that, I create avatars that will dominate and destroy the universe, crushing the life forms.]

When I asked why he needed to absorb nutrients when Outer Gods didn’t require such sustenance,

[Because they taste very good. The nutrients of life forms.]

…Just for the taste.

Additionally, he said he greatly enjoyed watching his creations dominate and crush other life forms in the universe.

It turns out that the demon kings of fantasy worlds, the ultimate cosmic beasts that rule the universe, and other destructive deities in various stories were actually creations of Ubbo-Sathla, made to dominate and destroy the universe to absorb the nutrients of life forms.

This insane being… So, you were the mastermind behind every demon king in all stories…!!

One might ask why he doesn’t just do it himself instead of taking such a cumbersome approach.

Well, it’s because he’s an Outer God.

If Ubbo-Sathla were to directly enter the universe, life forms would go insane upon encountering him.

Even touching him would cause them to disintegrate at the atomic level.

Before he could do anything, all life forms would either die or vanish.

This means he wouldn’t be able to absorb a large amount of life energy, and even if he did, his power would contaminate the nutrients.

So, he creates avatars to play his universe-destroying games instead of doing it himself.

And most importantly, it’s probably more fun for him.

Honestly, I can understand that.

If I were to do it myself, it would be so overwhelming that calling it overpowered would be an understatement. Naturally, playing a universe domination simulation game with avatars I created would be more entertaining.

[But sometimes, things don’t go as planned in certain universes.]

Ubbo-Sathla said, giving several examples.

For instance, it’s as if the universe itself creates adversaries to thwart his amusement.

These adversaries defeat the demon kings or destructive gods he painstakingly created, leading to annoying situations.

When that happens, he sometimes gets angry and creates even stronger avatars or steps in himself.

Anyway, to avoid such interference from the universe, he researched various methods.

One of them was to create a powerful civilization instead of an overwhelming individual.

This is how the Lubaran race was created in this universe.

However, this plan spectacularly backfired.

You can tell by the fact that the Lubaran race formed the Galactic Union and started protecting the universe instead.

He thought that if he interfered too much, the universe would eventually push back.

So, he created a race with exceptional abilities and left them alone as much as possible.

As a result, these beings advanced their science and, instead of dominating the universe, formed a union and became its protectors.

…Well, from the universe’s perspective, that’s pretty sweet.

From my perspective, a space opera genre is far more entertaining than having a bunch of insane demon king races causing chaos.

So, Ubbo-Sathla tried to create giant monsters to attack the Galactic Union, but even that wasn’t easy.

He even sent a demon king-level entity, close to an Outer God, but the Galactic Union, despite suffering heavy losses, ultimately triumphed.

…Oh, so that was why the Galactic Union was boasting about capturing a lower-tier Outer God.

It was his doing…

Anyway, Ubbo-Sathla ended up creating an adversary that protects the universe with his own hands.

What’s more concerning is that the universe’s will hasn’t created an adversary yet.

If he starts interfering more than just creating giant monsters, he’ll have to deal with both the Lubaran race and the universe’s adversary.

[It’s tempting to destroy everything out of annoyance, but it’s rare to find a universe that has developed this much.]

The entire universe is overflowing with delicious life forms, thanks to the Galactic Union led by the Lubaran race.

Although his interference has increased due to the Lubaran race, it has also enhanced the quantity and quality of the universe’s nutrients.

[So, I propose this to you.]

What Ubbo-Sathla wants is a life form like Eugene.

One that starts weak, preventing the universe’s will from creating an adversary.

Then, it grows and eventually becomes a demon king-level entity.

Whether he’s never created such a life form before or he lacks understanding of the concept of ‘growth’ because he’s been an Outer God since birth, he’s asking for my help.

He wants me to create a cosmic demon king for universe domination and destruction.

[……]

I mean, the story is incredibly interesting and entertaining, so I kept listening.

…But why would I help with that…?
