Chapter Text

The Great Green Beast stalks toward Tzeentch, both of his swords drawn and engulphed in emerald green flames. "You are the last of The Four, Tzeentch. At my hands and swords, Slaanesh's desires were crushed, Nurgle's filth was purged and his garden burned, Khorne's bloodshed was halted permanently, and now, all of your ten thousand plans come to an end." He declares, his voice booming even as the god of change grins at him.

"Indeed they do!" Tzeentch says with a laugh. "But not in the way that you think!"

The Beast pauses, his glowing emerald eyes widening behind his helmet. "...You planned this. You planned for me to do this, and I played right into it. All of these past ten thousand years of my life, I've been playing right into your hands." He states, rather than asks. Tzeentch's widening grin only confirms his suspicions. "Why? You know that there is nowhere for you to flee to, no way for you do escape. You will no longer exist in your current state no matter what after this moment, so why?"

"Why, to crush the current status quo, of course!" Tzeentch says. "What wondrous change will the eradication of Chaos and the purging of the Warp bring? Oh how I wish I could stay around to witness it!"

The Emperor's Final Masterpiece sighs. "I don't know why I'm surprised. Change for change's sake is your whole purpose and reason for existence. So, if I'm following your greatest plan, I'm guessing you're the one who brought me to the galaxy in the first place?"

Tzeentch laughs. "Of course! And, I would like to give you a reward for providing such great entertainment over the past ten thousand years!" He says as he raises a hand and snaps his fingers, causing a Warp Gate to open beside him. "Once you complete your final crusade by striking me down and imprisoning my soul in one of your swords, simply step through this gate, and it will return you home."

The Beast is hesitant to trust Tzeentch, but decides after a moment that a small chance of going home is better than no chance, so he nods and steps forward, plunging his left sword through the center of Tzeentch's body, causing a whirlwind to form as the entirety of Tzeentch's existence is sucked into the sword, thus imprisoning the last of The Four and ridding his influence from the galaxy as a whole. He then steps through the Warp Gate, hoping that Tzeentch spoke the truth.

As The Great Green Beast steps through the Warp Gate, the entire galaxy shudders at the loss of The Four, and everyone, non-psykers included, feels a shiver go down their spine as the Eye Of Terror closes once and for all. Immediately, every single space marine in the galaxy turns to face the direction where the Eye Of Terror once was, and salutes.

As The Beast's eyes open, they also widen as he finds himself in the upper atmosphere and begins rapidly falling. Thinking quickly, he shifts into a landing position as he approaches the ground, slamming into it like an emerald meteorite. He looks around after landing and, immediately recognizing the city he's currently in as the one where he was born and raised, he smiles, before stabbing both of his swords into the ground and sitting there, waiting for the authorities to arrive.

Less than ten minutes later, cop cars(oh how nostalgic it is for him to see THOSE after all this time) pull up to the crater he's sitting in, along with several people in costumes(heroes. He had almost forgotten about them).

"Lower your weapons. Bullets cannot penetrate my armor, and I have no intention to cause anyone harm." He calls out. "I will come along peacefully. If I did not intend to, I would have left my landing place, rather than sitting and waiting."

One of the heroes, his name is Death-something if memory serves correctly, steps forward. "Alright, just hand over those swords and take off that helmet, and we'll take you in."

"I can do the latter, but if anyone but myself touches my swords, they will doubtlessly die. In this world, only I can touch these blades without having my soul eradicated, and my body incinerated." He says, before taking off his helmet and offering it to the hero.

Instantly, all of the cops and heroes stare at his swords with wariness and apprehension.

"I will bring my swords with me as I follow you, and place them in whatever cage you require me to. If I leave them here to collect later, I fear some fool will attempt to steal them, and find himself annihilated by their power." He says, before pulling his swords out of the ground and placing them securely in the harnesses on his back and holding his hands out to allow them to handcuff him.

Naomasa groans as he finishes listening to the brief on the man currently in the interrogation room. "So, you mean to tell me that he just randomly fell from the sky like a giant, green, human meteorite, claims to have swords that are so unbelievably dangerous that they would kill anyone but him that so much as touched them, and he's refusing to talk to anyone that doesn't have a lie detection quirk?"

Sansa nods. "Basically, yeah."

Naomasa groans again, before running his hand down his face. "My vacation is supposed to start tomorrow, but I just know that this is going to upend all of my plans." He says, before grabbing the doorhandle of the interrogation room. "Well, wish me luck." He jokes, before pushing the door open and stepping inside.

Naomasa looks up at the green-haired giant and gulps. He REALLY hopes that this guy isn't a villain.

"So, first thing's first. I am legally required to disclose that my quirk is lie detection. I will know without fail whether or not you are telling me the truth as you know it. And, unlike most other lie detection quirks, I will also know if you are lieing by omission." He says as he sits down across from where the mountain of a man is standing(they apparently didn't have a chair large enough for him to use. That will need to be remedied in the future.)

The man nods. "Good. I would have sent you away otherwise. First thing's first, my name is Izuku Midoriya, and I am approximately eleven thousand years old." 

Truth

Naomasa's eyes widen. Hold on, what the fuck!?

"All but the first fourteen years of my life were spent in another universe's alternate version of the milky way galaxy, because of a plot by an evil god." He continues. "I spent the vast majority of time in that Galaxy fighting and killing daemons and aliens in an endless war. Approximately one hundred and thirty two years ago in my time, but five days ago in the galaxy I was summoned to's time, or less than a nanosecond in this world's time, I entered what many would consider Hell with the intent of eradicating the corruption that it brought on the wider galaxy and taking one faction out of the war. Approximately four hours ago, I defeated the last of the four main daemonic gods and imprisoned his soul and very existence within one of my swords. Specifically, he was the god that brought me to that universe in the first place, the god of change as his primary domain. The other three daemonic gods were the god of bloodshed, the god of plagues, and the god/goddess of excess. The god of change is imprisoned within the same sword as the god/goddess of excess. The other two are imprisoned in the other. I was returned to this world by the god of change as a reward for eradicating the influence that daemonic forces have on the wider galaxy, and thus causing a truly great change. From what I can tell, approximately eleven months have passed between me leaving this world and me returning to it, thus causing me to possess the theory that one month in this world is one thousand years where I have been."

Truth

Naomasa rubs his temples in frustration. Seriously, what. The. FUCK!?

"Okay, give me a brief rundown of exactly what you have done and where you've been." Yes he's digging for information. He knows that, and he is unashamed.

"Were I to attempt to give you the cliff notes version of my life, you would die of old age before I could finish."

Truth

Naomasa's not even surprised, to be honest. Well, not very surprised, at least. Eleven thousand years of war. Yeah, even the cliff notes version would take a long time to finish reciting.

"Okay, so, just... break it down into a version that can be told in a manageable amount of time." He says.

Izuku tilts his head. "Manageable for you, or for me? Because those two things are very different."

Naomasa stares at him. Right. Eleven thousand years old, obviously he has a very skewed view of time.

"Look, just... explain as much as you can in the timespan of an hour."

Izuku nods. "Ok, so..."

Naomasa slams his head on his desk and groans.

"That bad?" Sansa asks.

"We are dealing with an immortal, eleven thousand year old super soldier, who was made with the specific purpose of weakening and defeating four demonic gods. He has been fighting an endless war against daemons and aliens for almost all of his eleven thousand years of life. The worst part is that that description of him doesn't even begin to explain one percent of who and what he is. In terms of power, though? He could crush All Might like an ant, without exaggeration." Naomasa mumbles against his desk.

Sansa's eyes widen. "Oh."

Naomasa nods. "Oh is right. Anyway, he's been in another world where time moves so fast that a single month here is a thousand years there, since he was fourteen. Check the records for a missing fourteen year old boy named Izuku Midoriya, and call the contact listed on the file."

Inko wakes up with a start as her phone rings. Frantically, she grabs it off the table that she had passed out leaning on, where it is buried under a pile of newspapers and reports, and looks at the number. Her eyes lighten up and widen with hope when she sees that it's the police office. She takes a deep breath, lowering her expectations, before answering the phone.

"Is this Mrs. Inko Midoriya?" The call operator asks.

"It is, yes." Inko says, barely managing to suppress the shudder in her voice.

"We have found your son, Izuku."

Inko gasps, her hand flying to her mouth as tears of joy well up in her eyes. "I-is he alright? Is he alive? Uninjured?"

"I am glad to say that Izuku is alive, healthy, and presently uninjured. However... there are some rather pressing complications."

Inko frowns, her growing joy freezing as her heart plummets. "What kind of complications?"

"Please come in to the station, ma'am. I'm afraid that it would be much simpler for him to explain it." The call operator says, before the line goes dead. 

Immediately on edge and highly concerned, Inko throws on a random pair of shoes and rushes out of the apartment.

Chapter Text

Izuku stares at Inko.

Inko stares at Izuku.

"My darling boy... what happened to you?" Inko mutters, mostly to herself.

"To list everything in a summarized form would take a thousand years." Izuku says matter-of-factly.

Inko shakes her head. "No, no, I mean your body. Why... why are you so big? And what's with the armor?"

Izuku tilts his head. "That... is easier to explain. I was turned into what I am now by a man that I hold great respect and adoration for, that most people where I have been worship as a god, He modified my body and soul to make me a living superweapon, capable of shattering planets like glass, or snuffing out stars like candles. The size was my a result of my body being reshaped to contain my power without self-immolating. The armor was His final gift to me. Made from the same material as His own, it is one of only a few sets of armor capable of remaining intact when I get serious, as rare as such an occurrence is." He explains.

Inko's hands fly to her mouth. "You... you were used as a living weapon?" She gasps, horrified.

Izuku sighs. "I assure you, I was fully willing when He made me into what I am. At behest of His son, He agreed to make me into a being that would survive long enough to go home. In exchange, He made me promise to protect and serve His imperium until such a time that I was able to. However, as nobody knew of my being from a separate universe from that one, aside from Him, I, and the specific one of His sons that brought me to Him, I have no doubt that they are scouring The Warp in search of me, in order to rescue me from it, as a reward for what I have done. I'd give them about four or five hundred years, or about half a month in our time, until they discover the gate that I went through in order to return here."

"Hold on, you mean to tell me that there's going to be an army of supersoldiers showing up in search of you in half a month!?" Naomasa exclaims, blindsided by this revelation, that Izuku had not revealed during his interrogation.

Izuku shakes his head. "Well, not exactly. If it's space marines that show up, then by this world's definition it will be too small a force to be considered an army, and All Might on his own could probably deal with most of them if need be, though that shouldn't be necessary. The largest space marine chapters only have around a thousand members and, while they are superhumanly strong and fast, they're not strong enough to change the weather with a punch, or fast enough to casually break the sound barrier, like he is. Most of the top heroes could probably defeat a squad or four of average Space Marines on their own if they had to, with great effort, though that will likely be unnecessary." He says, easing Naomasa's worries. "Granted, I had heard that they were attempting to resurrect Guilliman when I invaded The Warp, so if he is with them when they arrive, and someone attacks him, problems may arrise. As a Primarch, even being the second worst combatant, Guilliman is a major threat to all but myself if on a war path, though he does prefer diplomacy."

And just like that, Naomasa's worries are restored. "What, exactly, is a Primarch?" He asks, worry in his voice.

"That will take some explaining. How much time do you have?"

Naomasa groans into his desk, again, after Izuku and Inko finally leave to go home.

"This is starting to turn into a pattern." Sansa says, amused. "So, what world-shattering revelation did he lay onto you this time?"

Naomasa glares at him. "Aside from his hopefully-hyperbolic claims to be capable of destroying planets and stars with minimal effort, he also revealed that we may be getting invaded by up to a thousand bio-engineered supersoldiers, possibly being led by essentially a demigod, in search of him."

Sansa raises an eyebrow. "Did you just say 'hopefully' hyperbolic?" He asks, confused. "Your quirk didn't tell you?"

Naomasa groans. "Just gonna ignore the possible invasion by an army of supersoldiers and a demigod part, then." He grumbles under his breath. "Anyway, yeah. For some reason, my quirk was suspiciously silent whenever he wasn't talking to me directly. It's weird. For some reason, whenever my eyes weren't on him, it was as if he wasn't there at all. Unless I had him in my line of sight, I couldn't hear his voice or breathing, or even do as little as feel his presence, which was so prominent whenever I was looking at him. I never took my eyes off of him during the first interrogation, so I didn't notice then."

Sansa rubs his chin. "That IS weird." He agrees. "Maybe it's one of the powers infused into him by the guy he said turned him into what he is?"

Naomasa sighs, leaning back into his chair. "I guess that that's possible, yeah. It would definitely make him more effective as the supersoldier, of sorts, that he was designated as. Anyway, we need to get in contact with the HPSC about the possible invasion that I was talking about. That should take more priority at the moment."

Inko looks at the door.

Izuku looks at the door.

Inko looks at Izuku.

Izuku looks at himself.

"Well... this is awkward... how are you going to fit through the door?" Inko asks, a concerned expression on her face.

Izuku sighs. "I always forget that normal-sized doorways can't fit me in this form..." he mutters, before he begins to shrink, his armor being replaced with a dark green suit as he visibly ages, until he eventually stops changing, having taken on the form of a 6 foot tall 40 year old man rather than his usual, 14 foot tall 20ish year old appearance. "This form is always so uncomfortable to take on..." he complains. "I don't like being this small or old."

Inko stares at him in shock as he picks up his swords, now a good 2-3 feet taller than himself, and shifts them to levitate behind him. "How... how did you..."

"It's something that happened to me back during the past 11,000 years." Izuku says casually. "Perpetuals with a certain level of power have their souls splinter into many different fragments, known as 'aspects' that each have different appearances and amounts of power, and sometimes personalities but not always. This is one of my weaker ones, known as 'The Kind Stranger' the aspect from before is 'The Destined King' and the aspect that usually comes out for battle is 'The Great Green Beast'." He explains.

Inko tilts her head. "The Destined King?" She questions, confused, only for Izuku to wave her off.

"Don't worry about it. It's just a title that I gave that aspect, nothing to worry about." Izuku says, though Inko doesn't fully believe him. "Anyway, come on, let's get inside, it's pretty late and, while I don't need sleep for but a few minutes once a millenia, you're a regular human who does need sleep." He says not-unkindly.
