"Have you gotten the results?"

"We've managed to analyze his blood samples, Ms. Smith...after 4 tries."

"Care to elaborate?"

"The first 3 tries we used normal syringes to penetrate his skin, and even aimed for where we thought was the weakest spots...and they all broke. We had to use one with a diamond tip."

"...anything else interesting you can tell me about him?"

"You won't believe this, Ms. Smith...he is technically completely human, at least in appearance."

"What do you mean, he's completely human? Underneath all that metal, there's nothing strange about his looks? No hidden horns, tails, scales, fur, or anything extra?"

"Exactly. He looks like a completely normal human from an outside perspective. He could even be mistaken for some sort of bodybuilder. Visually, there's nothing that can classify him as a liminal. But his body composition, his muscular and skeletal strength...well, that's another story."

"Assuming the fact he managed to beat up six orcs at once, that's quite obvious. Care to elaborate more, doctor?"

"Well, we had him run a few physical tests to determine his physical capabilities...although when we brought him to the test site while handcuffed, he managed to break those cuffs easily before we could unlock it."

"Doesn't sound all that impressive."

"Those cuffs were designed with alloys created to be able to restrain fully adult ogres, ma'am."

"...duly noted. Anything else?"

"He was capable of lifting the equivalent of 1 ton of weight, with one hand. He could run faster than some of the best athletes on record, and he was able to keep it up for minutes without breaking a sweat. I know, I've seen it myself. What's even stranger is that his heartrate didn't increase by much throughout the whole test. For him, it was almost like a simple morning jog. Almost like he was pretty used to it."

Smith narrowed her eyes in concern. This, man, and that's using the broadest possible meaning of the word, is far beyond any normal human, and even most liminals. The idea that he could be an alien for outer space might actually sound plausible at this point, but he looked so human. It doesn't make sense.

"There is...something else, that you might be interested in hearing, ma'am."

Smith raised an eyebrow.

"Entertain me, then."

"We found an..unidentified element, coursing within his blood cells. Huge amounts of it, in fact. We couldn't assume much, buuut it is likely the same element can be found throughout his whole body."

"What do you mean, unidentified?"

"That's exactly it, ma'am. We've never seen anything like it before. It doesn't belong anywhere in the periodic table."

Now that really got her attention. An element not found anywhere on Earth, flowing inside this man's bloodstream? Somehow, that space alien theory is starting to sound credible.

"What about his suit?"

"We had our guys cleaned the suit from, whatever the stains were and...it's even more ridiculous, to put it simply. We performed all sorts of endurance tests on its surface, and we couldn't even put a scratch on it. It's like the metal itself is some sort of a Vibranium rip-off, pardon the reference. We also couldn't find any energy sources which could potentially power this suit, if it even requires one. Although we did found some strange markings and symbols we don't quite understand, including numbers which could indicate that it's potentially factory-made. Whatever it is, one thing's for sure: this suit is far more advanced than what humanity is currently capable of."

Okay, so that means space alien, or a Terminator from the future. Somehow, both of them sounded very much plausible at this point. It was grating on her mind. This man just shows up out of nowhere, ruined her operation, and everything about him just, baffled her. This wasn't enough. She needed to get some answers, one way or another.

She sighed. "...alright, bring him in."

The alarming sound of a phone broke her thoughts. It was the doctor's phone.

"This is Doctor Nasui speaking...huh?..what do you mean?...What!? How!?...uh huh...so what now?...oh...alright. Keep me in touch."

Smith had a curious look on her face. "Excuse me, doc. Is there something wrong?"

The doctor only sighed. "I'm afraid so, Ms. Smith...he's gone."

"...I beg your pardon?"

"The man in green. He..escaped. Somehow he got through all of our security personnel, bypassed the systems and escaped the facility. Additional reinforcements have been called in to begin a search. I could only hope he hadn't gone far, but knowing what he's capable of, our search may take much longer than necessary."

Smith frowned, her eyes narrowed. She may be lazy about her job, but she still takes it seriously. This man...is an enigma. It's hard to classify him as a liminal since he doesn't seem to originate from anywhere, and he was very much indistinguishable from a normal human from a stranger's perspective. He could be a danger to both humans and liminals alike, and his presence could affect Interspecies Exchange Bill which could bring negative consequences in the future. The relationship between humans and nonhuman species are quite fragile as it already is, all it would take is a small but deep cut, to sever the ties.

Six hours before

"L-LET GO OF THE GUN, SIR!!!" One of the police shouted, while aiming his sidearm towards the green behemoth that took out a group of orcs within the span of a minute.

The Doomslayer held his energy pistol aimed towards the orc's forehead, the one currently visibly shaking in terror while lying in front of him. He doesn't want to hurt these people, but he's also hesitant about letting the pigman who disgustingly tried to rape an underaged girl walk away, alive.

In the middle of all this tension, the voice of a particular AI surprised him. "I have calculated the best course of action for us to take in our current situation. Doomslayer, I suggest you de-materialize your weapon and listen to their demands. Your actions have caused a mental disturbance towards these officers and the civilians involved. The most efficient way would be to act friendly and be cooperative with the government forces in charge, at least for now. It is the only way to avoid possible casualties and further complications for ourselves."

No. He had been used once, and look where that got him. He does not intend to be used like a puppet, only to be betrayed again at the end. He still hadn't settled his score with Hayden. He intended to get his Crucible back, one way or another.

"I understand that you're hesitant about this plan, but I highly advice that you establish yourself as a friend towards these humans and nonhumans as well, rather than an enemy. We are in an unknown dimension outside the UAC's known influence. However, the presence of Argent energy in this world suggests that we may not be that far off from our home dimension. We are just as clueless about this place as they are about us. If we come to an understanding, perhaps some beneficial help or information could be gained, that is, if we can gain their trust. These humans are merely reacting naturally towards an anomaly they do not understand, they are not your enemy."

The Doomslayer didn't like this plan, not one bit. But he trusted VEGA. The AI was responsible for helping him repel the invasion on Mars, and giving him a way back to Hell, and deal the final blow to the Mastermind. He was grateful enough to even save a backup copy of VEGA before his imminent destruction, even though the AI itself wasn't bothered by its own suicide.

So for now, he would comply. He doesn't trust the humans, but the AI was never wrong, thus far. If the humans would dare try to betray him again, he could always just escape on his own volition.

It's not like they could stop him. Hell, even Hell couldn't.

He dematerialized his pistol. The orc in front of him surprisingly had already fainted. Probably due to fear.

"Uuhh...okay, put your hands up where I could see them!!!" One of the officers, still pointing their guns on him, demanded out loud. He put his hands up in the air. But it wasn't enough.

"Open your helmet."

A lone woman wearing sunglasses amongst the crowd of policemen demanded from the Doomslayer, just loud enough for him to hear. But he didn't like it. Asking him to remove his helmet is like asking someone to cut their own finger off. At least, that's what it felt like to him.

"I will not ask you again, open your helmet NOW."

He gritted his teeth, but he decided to comply anyway. He wouldn't want to hurt these people right now. They wouldn't be of much help anyway if their limbs are broken.

As a long hiss was heard, the helmet that he had never took off since his awakening was now detached from the rest of his armor, allowing his face to be seen by everyone. Needless to say, everyone was jaw-dropped.

From a female's perspective, he was, handsome in a way. He had a rough look on his face, a sharp jawline, and the wrinkles indicate that he was quite aged. He had short blonde hair that seemed like it was combed to the front, and brown eyes. Overall, he looked quite normal.

Aside from the fact he apprehended six orcs with savage brutality, and didn't even break a sweat while doing it.

But what bewildered them the most, is that he seemed completely human.

No human could have done all that.

Smith narrowed her eyes. His face looked human, but he might have a tail or a furry body, which was why he was covered in armor. Maybe he was just shy? But if this guy was indeed human, that would make everything even more complicated than it already is.

"Your actions, however "heroic" they might seem, have disturbed our entire operation. Not to mention you have violated the Interpecies Exchange Bill with your actions. We have no choice but to take you into custody. GIRLS!!!"

The rest of the MON squad finally showed themselves after keeping quiet throughout the ordeal. "Man, I didn't even get to shoot my guns!! What's the point of being dead if you can't live a little?" Zombina voiced out her annoyance over not being able to have "fun".

"Why do I have to be over two kilometres away? It's hard running back here with this rifle, it's too heavy!" Manako also complained about her own misfortune.

"Oh shut it, at least you guys didn't get molested by those pigs. I had it way harder, you know!" Doppel also decided to join in on their little discussion on who had a much worst day.

"Come on, Pel-chan. We all did well! I mean, we didn't do anything in the end-but at least mission is accomplished!!" Tionishia tried to calm down her teammate with a cheerful expression.

Although, deep inside, none of the MON squad were feeling happy, or even relieved, about the sudden turn of events. How could they, when a random stranger in green suddenly came barging in and did all of their work instead, and are now possibly taking the credit for it.

"Ehh!? So this is the guy who took out all those orcs? But he looks human!!" Zombina, finally taking a good look at the armored man's face without his helmet, couldn't contain her surprise.

"Maybe he's actually a doppelganger like me, and he's just disguising as a human. And yuck! What is that horrible stench?" Doppel voiced out her own thoughts, followed by Tionishia, "Are you sure, Pel-chan? I've never heard of a doppelganger who's this strong! But you're right, this man smells kinda weird..."

In the midst of the situation, Smith decided to bring an end to their little chit-chat. "Pipe it down, you guys. Arrest the criminals, and do it quick. Officers, I want you to restrain Mr...umm...right, you never told us your name." Everyone's attention was focused back on the man in green.

The Doomslayer gazed towards the people around him. They wanted to know his name, simple as that.

The problem is, he didn't remember his own name. He had forsaken it ages ago. Even if he did, he wouldn't dare tell anyone. So he did the only thing he always do: he kept silent.

"...come to think of it, the green dude never talked once, did he? Is he a bit cuckoo or something?" Zombina pointed out. "Maybe he's just mute." Doppel stated it like it was the most obvious thing ever. Smith narrowed her eyes in suspicion. Doppel may have a point. But then again, this man might simply be playing the quiet game and refused to give away any information. He could be a spy working for an organization that might be up to no good. But a spy wouldn't let himself get caught by the police in the middle of a crime scene, right?

"It doesn't matter. Officers, please escort Mr...Green here, to the car. I'll deal with him later." The officers reluctantly cuffed the man in green, while holding their breaths so as not to smell the foul stench seemingly coming from the man.

She opened her phone to dial a specific number. She needed to inform her superiors about her current situation. The media must not know about this. This man is an anomaly. He cannot be human, however it is unknown what species he actually is. She can't let the local police arrest him, he's far more dangerous than a normal human. Maybe he's an entirely new species that hasn't been discovered, until now apparently. She had a friend who happened to be a scientist involved with the Cultural Exchange Program, and he knew about pretty much every liminal species out there. And then there's the suit.

His suit looked like it was made of metal, and that's all she could gather. Everything else about it looked completely alien, like it came out of a sci-fi video game or movie. Not to mention it was covered in something that looked like blood, which was never a good sign. And the stench.

It took her a while to realize the horrid stench coming from the man's suit. That would mean those blood were real. This is definitely not a good sign. Everything about the man just doesn't belong here.

She hated this, she hated having too many complications. This meant there would be less time to slack off at Kurusu's household. Which meant less time to enjoy his heavenly coffee brew. Her original plan was out of the window, now she had to deal with the aftermath.

She just hoped this day would not get any worse.

Back to the present

Smith internally cursed herself for jinxing it. Of course, this day would get much worse.

Now the man that had been the cause of her pain and suffering had somehow escaped, the Cultural Exchange Security Squad are at full force searching for the so-called "Green Behemoth", though in her own opinion, that name actually made quite a lot of sense. She gritted her teeth in frustration because she knew this would mean a lot more work to do.

And she was really looking forward for some Kurusu-made coffee tonight.

She didn't care anymore if that man was some kind of half-human, half-robot killing machine or a supersoldier.

When all of this is done, she's gonna kick that guy's ass.

Author's Note

So...this chapter doesn't have as much ripping and tearing as it's supposed to, which is totally a sin considering this is a Doom fic. Sorry about that. There will be more ripping and tearing in the next one. And demons might also make an appearance.

Also, I might have made some of the characters here a bit OOC. And if I did, I apologize. I tried my best to make it work. I'm still an ameteur.

So some of you might be wondering: what gave me the inspiration to write this story? I mean, Monster Musume spliced with Doom sounds like a recipe for disaster, right? But that's the thing, as much of a disaster it could be, we just can't take our eyes off it.

I've actually read other fanfics involving Doom Monster Musume. Now don't get me wrong, I LOVE Doom. But I'm not a real fan of Monster Musume, so why did I still write this fic? Maybe because I was...unsatisfied?

The other fics involving Doom/MonMusu that I've read are a bit dissapointing for my taste. Most of them basically involves Doomguy/Doomslayer as the replacement for MC-kun in the anime/manga, and the story progresses almost the same way as it did in original source material. I'm NOT trying to offend the other writers out there, but I'm just stating my opinion. I mean, it's DOOM. Why not change it up a bit? Where's all the blood and gore? Where's all the ripping and tearing? Whatever crossover fic you want to make, if it involves Doomguy/Doomslayer in it, there's bound to be some demon-killing in it, followed by some hardcore metal. That's just how Doom is. And so, by the power of my imagination, this fic came into existence.

Hope you enjoyed this chapter, and ciao.
