Yes, I like Attack on Titan. Yes, I like Eren x Levi. Yes, I also like the T.V show Supernatural. Figured that I'd make an AU with ALL of these purdy elements in here.
You don't have to be watching Supernatural to read this- I'm just using the guidelines and the basic biographies for the freaks on that show so I have something to go off of here. I will be explaining the weaknesses, what they are, and etcetera in the actual chapter they appear in, or in the Author's notes. If I don't, message me so I can add it. I'm a little prone to forget little details.
As a first thing to know about me- I really don't like pulling things out of my arse so quickly, and repeatedly. Once in a while, sure, but I don't feel like summoning new creepy crawlies every time Levi and Eren team up, so yes. Sorry if the format to this chapter is a little….finicky.
And sorry it's so short. I figured that if I don't get something published, I never will. More will be coming.
Please, enjoy.

It wasn't too dark outside, Levi could see quite well despite the lack of light. He stepped around the rubble of the broken house on the outskirts of a town, not wanting to make a sound to show that he was there. An old picture frame was broken and splintered, the actual picture faded. He took out his pistol, loaded it, and held it at ready. He continued past the picture and into another room. From the couch and the coffee table, Levi figured this was to be the living room.

Earlier on in the month there had been a couple of disappearances here. Erwin called Levi to investigate and to take care of whatever was here. Hanji wasn't able to gain enough information, and neither could Levi even though he did his digging. All they could find were grave desecrations in a nearby cemetery. Levi suspected Ghouls, but anyone could dig up a grave. But taking the body…Levi guessed kinky fetishes if whoever did this wasn't a Ghoul. Another thing they found were two missing kids, and possibly a third.

He slipped the clip from his pistol to check it. It was filled with semi-illegal exploding bullets. Well, they were in fact incredibly illegal and Levi didn't give less than a shit about it. He couldn't get anything else. Levi would never admit this, but he forgot to do his errands this week and was dangerously low on ammo at home. That and toilet paper for God's sake.
Ghouls were creatures that ate the flesh of the dead, but they do switch to living flesh sometimes, flesh of humans. They have shape shifting abilities, but they can only change into the person they just ate, and the only way to kill them is either extreme head trauma or decapitation.
And so, exploding bullets.

Slipping a hand into his pocket, he pulled out a folded paper. He opened it and gazed at the two pictures on it. It was a missing poster for Armin Arlet and Mikasa Ackerman. None had any living parents or relatives to look for them other than Eren Yeager, but the people in the town they were all from hadn't seen them recently. The last time the locals saw Arlet and Ackerman was around this old house, but because of the grave desecration Levi suspected that if a Ghoul or whatever was around had gotten to them. Either Arlet and Ackerman were dead with Yeager M.I.A, or all three of them were dead.
Slipping the paper back into his pocket, Levi just hoped they were all together in some way, shape, or form. Preferably in one piece if whatever he was possibly hunting got a hold of them. He didn't want to pick up the pieces.

He stalked around the corner and avoided an upturned table, looking around the dirty counters. He didn't try to hide his disgust at how unclean this house was. His skin was crawling. There was a loud thump and Levi tensed up. He stopped moving and heard the thumping getting closer to him. The male didn't know what was coming so he hid behind the upturned table, holding his pistol aloft. He heard whimpering, and a shuffle of objects. Before Levi could react, a giant wolf was looking at him right in the eye. Levi let out a breath and he didn't move. The wolf's own eyes mirrored Levi's look of shock and slight panic. The animal backed away and sat on it's haunches, looking at Levi with a tilted head. Levi had never seen a wolf this big before, and it made him a little uneasy. The animal must have seen Levi twitch his pistol because signs of aggression seeped onto its face. Its lip curled and a low growl echoed throughout the room. Levi didn't really fancy being killed today so he let the gun slip out of his hand, his eyes locked on to the wolf.

As soon as he let go of his gun, the tension in the large animal left, and its lips covered its teeth again. "Okay…How do I get out of this one," Levi mused, moving back slightly. The animal had begun to twitch, closing its eyes as if in pain. Whatever it was doing, Levi didn't like it. The wolf stayed seated and in a matter of bones cracking and some grunting, the wolf became a human boy. Levi had only blinked and the transformation was done. His eyes widened and the boy's own eyes copied, widening as well.

"D-Don't run please!" The boy blurted out, lunging forward to place a strong hand on Levi's shoulder. Ignoring the fact that the boy was fucking naked, Levi stayed where he was. In his mind he was quickly crossing out the freaks he has hunted who could change from a wolf, or any sort of canine, to a human. One kind of freak stood out in his mind.

"Skinwalker," Levi said bluntly, and the boy flinched. Levi instantly went for his gun, being thankful that he packed the exploding bullets instead of normal ones. At least these can do some fucking damage. Originally you'd shoot a Skinwalker in the heart with a silver bullet, but Levi guessed that a blown off arm or something would slow it down. He stood up and took aim and the boy yelped out of surprise. Levi didn't shoot, however. This boy didn't seem like he was going to attack- he changed into a human. Levi would give him a chance to speak, "What do you want?" He asked.

"Help." The boy croaked, looking at the gun that was pointed to his heart, "I want help."
Levi lowered the gun a bit, feeling confused, "Why would you need my help, brat?"

"I'm looking for someone, two people actually. They vanished here and I don't know where they are."
Levi stared. He was looking for two people, who were last seen here, "Are you talking about Armin Arlet and Mikasa Ackerman?" The boy brightened at these words and smiled slightly, nodding. Those eyes of his were big and fuck if that didn't make Levi feel, strange. They weren't normal, to say the least. And to call them a simple green was almost like an insult. They were like a fucking ocean, or a lake in a mountain that was pure, and untouched by human pollution and garbage. A nice, calm body of clean water.

Levi lowered his gun so it was limp at his side. He let out a weary sigh and put his free hand to his hair, his fingers raking through it, "I'm looking for them too, sort of. There were grave desecrations near here and the fact that those two are missing make it even more obvious that something is here." He looked at the boy pointedly, and it seemed the younger got the message. The boy twisted his face in disgust, "Oh God, no way," the younger muttered.

"So, you need my help because you can't find them on your own?" Levi asked, and the boy nodded again. The older male was having a hard time keeping his gaze locked with the others because the lack of clothes was…awkward. Did this brat have no shame at all? Levi kept a blank face on, and his tone was even more emotionless, "Well, I hope you know that we're going to be looking for their bodies so don't-"

"Take that back."

Levi stopped talking, now looking at the boy who was standing. He was taller than Levi and it would be an understatement to say that it just 'irked' the hunter. Levi stood his ground, staring at the boy, "What was that, brat?" He spat, not liking where this was going.

"You said they were dead. I said to take it back." There it was again, the demanding voice. The boy's brows were furrowed, his mouth pressed in a thin line. Levi noticed that his eyes changed from that green-blue hue and became almost like a green-yellow. A wave of something hit Levi and he took a step back. There was something unnatural about this boy, other than the fact that he was a skinwalker. But in all his years of hunting your worst nightmares, he had never been scared. Why did he feel frightened now?

The boy's eyes narrowed further and he leaned forward a little, his shoulders hunching. It was almost like he saw Levi as prey, "I said take it back. They aren't dead, I can feel it. That much I know."

"Fine, brat. They aren't dead, we'll find them." Anything to calm this kid down. The vibe coming off the brat was a little concerning, but as soon as Levi said those words, the boy calmed down, letting out a long breath that he had been holding.

"What's your name?" Levi asked, still feeling on edge.

"Eren Yeager."
