Supernatural Management Division: A Marvel Avengers x Supernatural Crossover

Right. Just Vampires: 2013

Sam and Steve walk down a hallway of the Helicarrier.

Sam looks at Steve. "So what do you know about the Supernatural?"

Steve laughs to himself. "Honestly? Not much."

"That's okay. We're only dealing with vampires right now, and they're pretty easy to get your head around."

Steve nods sarcastically. "Right. Just vampires." He stops outside a room with computers lining every wall. "You know anything about tracing gang history?"

"I wouldn't know where to start."

Steve smiles. "We're gonna be a good team then."

Bruce cuts into Tekin's arm with a scalpel. He pauses, looking up at Tony and Castiel from his chair. "So you're telling me that these are vampires?"

"No, he's a vampire." Tony points to the headless body of Devin Harris. "You're gonna tell us if this guy's a vampire too."

"You want me to compare the anatomies to see if they match. I know. But they both appear to be human, Tony. Everything seems normal."

"You haven't checked everything." Castiel looks between Tony and Bruce.

Tony's eyes widen and he looks at Bruce. "Let me cover my eyes if you're going down there."

"No, I don't mean there." Castiel rolls his eyes. "The teeth."

Bruce nods in realisation. "Of course. I knew what you meant."

Bruce throws Tony a glare and Tony shrugs.

Bruce turns to Devin's body and then stops. "Ah... It's going to be hard to compare teeth when this guy's missing his head."

"Trust me Banner. You won't need to compare to know." Tony grimaces.

Bruce swivels back to Tekin, scalpel in hand. He hesitates. "Any suggestions?"

Tony raises his hands. "Don't look at me."

"Here." Castiel puts on a pair of gloves and walks to behind Tekin's head. He lifts Tekin's upper lip with one hand and points with the other. "Cut along here." He drags his finger across the gum.

Bruce looks at Castiel, concerned. "Okay."

"And you haven't seen any nests in the area?" Dean taps his pen on the table impatiently. "No reason, let me know if you hear anything.

Dean hangs up and crosses another name off of his list. He sighs, picking the phone back up and hitting in another number.

".... Hey, yeah. Do you do burgers on this ship?"

Clint dumps a heavy duffel bag down on the floor in front of Natasha. "You ready?"

"Almost." She pushes the sides of her duffel bag open further and puts two swords down the side.

Clint looks surprised. "You're taking Samurai Swords?"

"If you mean Katanas, yes. If there's even the smallest chance we're walking into a vampire nest, we're gonna need to be able to behead those bitches quicker than they can kill us. And that's gonna be quick."

"You think my exploding arrows will be enough?" Clint looks down at his duffel bag.

"They should work, but take a blade just incase. You can use Dead Man's Blood to weaken them first, but there'll be no room for error on this one."

"I'll assume Dead Man's Blood is a literal phrase?"

"You'd be assuming correct." Natasha zips up her bag.

"And you really think I'm the one you should be taking in to kill a bunch of supernatural beasts?"

"I mean technically they're monsters, but I suppose that wasn't really your point... Listen. If the deadly Hawkeye can raise two kids in the middle of no where, I'm sure he can kill some monsters. It's nothing in comparison, honestly."

"But you're gonna bring the Angel, right?" Clint raises an eyebrow.

"Of course. He'll be on standby if we need him. Along with the rest of the team. We're going to make our own way over to Istanbul though, make sure we leave a trail for them to find."

"Sounds like a plan."

Natasha and Clint lift their bags into the boot of a car, and both turn immediately as they hear footsteps coming from the staircase.

Tony, Bruce and Castiel appear one by one, Bruce holding a plastic petri dish in his hands.

"We got something." Bruce says, taking the lid off the petri dish.

Clint and Natasha walk over and see the two sharp teeth in the dish.

"Holy crap, they're huge." Clint blinks a few times.

"They're Tekin's?" Natasha looks at Bruce.

"One's the one recovered from the field, so Devin's. The other's Tekin's." Bruce closes the lid.

"So Dean was right? We could be dealing with a nest?" Natasha looks over to Castiel.

"Unfortunately. We won't know for certain until we get over there and check it out. But it looks like they're all together." Castiel looks concerned.

"That's not all." Tony adds. "We found traces of the same blood in both bodies."

"That's not unusual. They both could've been feeding from the same animal." Natasha frowns.

"Not quite. The traces in Tekin were in his bloodstream, it was foreign but it had been there for a while. The traces in Devin were found in his stomach. It hadn't been properly digested."

Natasha sighs. "So you're saying that Devin did actually drink from Tekin?"

"How does that work? Can they drink each other's blood?" Clint looks confused.

"When they do, they draw out any human blood that's within the other's blood stream. Their own blood stays within their system." Castiel explains.

"Why does him drinking Tekin's blood matter?" Clint questions.

"Because it debunks his story. He didn't defect from a nest because he only drank from animals... Which means he was probably in Istanbul."

Natasha's eyes widen, she looks to the ground.

"What?" Clint looks at her, concerned.

"I've changed my mind." She doesn't look up.

"What do you mean?" 

"We're all going. We're gonna take the whole team to take down these son's of bitches. Let's finish this for good."
