Marvel: Tony Stark's Journey in the Omniverse

After a couple days, I'll probably move this chapter to after the Dr. Who chapter since it doesn't belong here. I first want to say that all of you should thank ASURA69s who left me a very nice comment at the end of the last chapter. I had decided against posting this because it was not finished but after reading his nice words I felt empowered to keep writing. And write I did! I think this chapter will be considered canon, if you have any reason to think it shouldn't please let me know, I might just make it an Omake chapter in that case. I am opening the door for your critique people, have at thee! I used Omniversal Travel as a plot device to drive my novel forward never giving it a real explanation. I thought to myself how is that any different from assigning my character a random system, R.O.B. assigned powers or a ring grandpa. So I spent days pondering on making it real, giving reasons as to why it works how it works and what I wrote below was the answer I came up with. Also thank you DannyFlash129, rex_of_dreams, and Sabine_Bailey for the powerstones today. It pushed me back from the 100th place to the 90s. Without further ado here is your chapter.

-------------------------------------------------------------------

I sit cross-legged on my childhood bed, a tangle of plastic models, books, and tools scattered across the floor like an explosion of a Lego set. I'm small again, just a child in body, but inside me churns a storm of power and questions. The void journey I took from my original world to the Marvel Universe left its mark. Not just in memory, but in what it helped awaken. Or maybe more accurately, what it helped me become.

I don't have a lab right now, no billion-dollar R&D suite humming with the latest tech. No AI assistants or scientific assistants armed with spectrometers able to analyze and dissect the phenomena surging in my veins. But I do have a brain. And more importantly, experience. So, I theorize.

First, there's my psionic potential. The moment I performed the awakening experiment—simple in appearance but layered in complexity—it was like a switch flipped. My mind and soul aligned and opened, and I unlocked teleportation. A proper psionic ability. Not just a gimmick. That was the moment I truly changed. Psionic energy began to ripple through my soul, potent and alien, yet intimately mine. But that wasn't all. No, there was something more.

Omniversal energy. That's what I've started calling it.

Theory one: I acquired it during the awakening. The Quantum Neural Accelerator, which is the device I designed to bridge the mind's latent abilities with the infinite energy of the universe connected me to energies from, well beyond the wall of reality. That sudden rush of mental and spiritual clarity I got by synchronizing my brainwaves with quantum energy fields acted as a beacon, drawing in forces from beyond the veil. In hindsight it kind of makes sense it turned out this way but you know what they say about hindsight being in 20/20 vision.

Theory two: More likely, I was exposed to omniversal energy during the journey itself—the passage of my soul from my original universe into the Marvel universe. That place between places. The Void in between here and there. A realm of nothing, and everything. I don't think I passed through it unscathed. I think I absorbed something.

You see, I suspect the void between universes isn't truly empty. It's saturated with what could best be described as spatial radiation, void energy or background omniversal energy. Normally, you might not take it in. But without a body—without a filter—I think my soul absorbed it. Like a dry sponge tossed into an ocean.

It was lucky, in hindsight. Not just because it may have given me more power, but because it probably kept me alive.

As I drifted through that void, I saw... things. Shaped in size and scale beyond comprehension. Forms that shifted in geometries not meant to exist in three dimensions. Entities that moved in ways the human eye can't process. Eldritch. If Lovecraft had glimpsed even a fraction of what I did, he would have wept blood, laughed maniacally, and then died screaming with a smile.

But they didn't see me.

Why?

Because I wasn't visible to them. My soul had soaked in the same energy that filled their space. To them, I wasn't an intruder. I was part of the static. Background noise. Camouflaged.

So I survived. And more than that, I brought something back.

This omniversal energy isn't just abstract. I can feel it. It's spatial in nature. Dimensional. And maybe—just maybe—it could resonate with things like the Space Stone. In this Marvel world, Infinity Stones aren't just myths. They're real. The Space Stone is essentially a condensed mass of spatial energy, right? Could there be synergy? Could I amplify or stabilize my own power through it?

A lot of assumptions. But assumptions lead to hypotheses. And hypotheses can be tested. Eventually.

For now, what I do know is this: the combination of psionic and omniversal energy almost destroyed me. My body wasn't built to handle it. Like running macOS on a toaster. The software was incompatible with the hardware. I had to rebuild, to enhance, genetically upgrade, and cultivate the kind of vessel that could handle this power. Like I did with Tony's body the moment I entered it. That process still isn't complete, I still have room to grow.

I'm on a new path.

Omniversal energy, or void energy at its core, seems to be the key. Not just figuratively, but literally. It's the thing that lets me travel. That lets me slip between walls that should be unbreakable. A universal master key opens a door to the void and then spits me back out somewhere random… For some reason. Most likely because I'm not meant to be there, yet.

Now the question becomes: what doors do I open next?

But first... I need a lab. And a sandwich. Probably in that order.
