Sherlock meets the Avengers- A crossing of fandoms

Welcome to our mess

Sherlock and John had just gotten back from the police department. Lestrade had tried to give them a case, but sherlock solved it where he sat and made a snide comment about lestrade needing better trained men. Mrs Hutson had the tremendous luck of being with friends for a few days, being able to avoid sherlocks grumbling about he lack of hard cases. Luckily, John was spared the horror as well. The second they got out of the cab at 221 baker street, stepping onto the sidewalk rather quickly as the cab decided againsed waiting for the two men to get clear, sherlock shoved his hand over Johns mouth and pointed to his gun, grabbing his and heading for the door. John was rather confused, but got the idea. Silent and armed. The door was not quite closed. The little pin that held it shut had dent gone into the hole of the door frame, leaving an obvious indication that the place had been entered. Sherlock always closed the door fully, as did John. They pushed the front door open silently, holding their guns in two hands and crouching, spy creeper style. They made sure to avoid any creaky spots on the floors and stairs, wanting to be totaly silent. Once in front of the flats door, sherlock nodded silently to John before kicking in the door and yelling.
"MOVE AND I SHOOT!!" He cried in a rather loud tone, even for sherlock. "What is it that Moriarty wants this time!? It's been a few months by now!" He added in a growl. There was one man in the room, calmly sitting on the couch. He had dark chocolate skin and a black eyepatch, desideing to rock some cheesy matrix 3 coat shit.
"Sh-sherlock..." John stuttered, he had focased on searching the rest of the flat and watching sherlocks back. So, he was the one to find the others in the kitchen.
"What!? I am clearly Buisy!" Sherlock growled, stepping menacingly towards the man smirking at him from the couch.
"To Buisy for us?" A man with a voice that could not be matched spoke up from behind sherlock. No, not Moriarty, but Tony Stark. Sherlock recognized the voice instantly, his eyes going wide and his face getting paler. He turned around franticly, spinning at a speed that would make a ballerina proud. He stumbled back a little, seeing that it wasn't just Tony Stark there, but the entire avengers gang, Steve Rogers, Natasha Romandof, Clint Barton, Bruce Banner, and Thor Odinson. They were all standing right there! Sherlock almost let out a little yelp when he found that Steve was standing a Meer foot away from him, sherlock comeing face to take with him. Now he knew who the man on the couch was. Nick Fury. The one man in the world that can order these people and a god around.
"Holy shit..." Sherlock mumbled, eyes still wide. He seemed to remember what he was doing and regained his composer, straightening and putting away his gun, allowing color to return to his face and forcing his eyes back to their normal size.
"Danm, that's faster than most regain their composer. Props." Clint laughed.
"Thankyou, Mr Barton. John, are you ok?" Sherlock asked, slightly concerned. John simply nodded, took a deep breath wile pinching the bridge of his nose, contemplating his life for a moment before speaking.
"Y-ya. Wow. I never thought living with a psychopath would lead to me meeting the avengers of all people." John marveled.
"High functioning sociopath. Do your research. We've been over this." Sherlock smirked. John walked over to him and smacked his arm. Both men had put their weapons away as they were speaking.
"Oh ha ha." John grumbled sarcasticly.
"Anyway. Might I ask why such high profile heroes are doing I'm our flat? Especially breaking into our flat? I don't think we have much to offer. Or, are we getting drafted, Captain?" Sherlock smirked, clearly likeing the minor adrenaline rush.
"Ya, very funny. Look, we aren't the kind to ask for help very oftin, so consider yourself lucky. We need you to help us find Loki. He landed in America a few days ago and we can't seem to locate him." Tony grumbled, clearly upset about needing help from a British detective.
"What!? No way! I am not going to let you drag either of us into your mess! The last thing we need is to be messing around with an evil god!" John panicked, only giving sherlock time to let his smile grow.
"Although I do want in, doesn't shield have their own detectives?" Sherlock inquired, haveing way to much fun with this.
"None as good as you. We are useing our resorces." Fury stated, the man finaly speaking.
"Hmmmmm... can you ensure at least Johns entire safety? If we do this, I would rather be the one to parish. Besides, John could handle it. He's morned me before." Sherlock laughed. John froze momentarily before smacking sherlock harshly on the back of the head, causing a part of sherlocks neck to pop loudly.
"That was the most crule thing you will ever do! You made me watch you jump off a building! Sherlock! I watched you die! I should have killed you myself when you came back! Belive it or not, I was about to propose to Mary when you came back!" John ranted forgetting about the audience.
"Belive it if you wish, but I did that to save your life. Moriarty had a gun pointed at you and everyone I loved and still love today! So if you think for a second I was being selfish then you can go jump off a roof yourself!" Sherlock informed, that shut John up instantly, the whole room had gone silent. John had never known that. "Ahem... anyway, back to buisniss. I didn't fake my own death just for John to die on a case. Can you ensure his safety?" Sherlock questioned, switching from the uncomfortable topic.
"Oh! Of corce, your safety will be assured as well. Both of you will be completely protected. It's a pretty big feat to be in harms way when your staying with a god, two assassin's, a supersoldier, the Hulk, and a mad scientist with a metal suit." Clint laughed.
"Hey!" Tony yelped, slapping Clint in the arm.
"You clearly know nothing about Sherlock Holms. He is litteraly a beacon for all forms of danger. He will probubly find a way to electrocute himself with Captain Rogers shield." John smiled, causing sherlock to frown.
"That is the biggest lie I have ever heard." Sherlock growled. "But, we're in. When do we leave?" Sherlock smiled, putting a hand on Johns sholder.
"As soon as you've packed. By the way, I fixed your microwave." Tony smiled.
"Oh, come on! I broke that on purpose. Sherlock kept putting live mice in that thing and seeing how long it took to make them explode!" John wined.
"SIENCE!" Sherlock yelled as he ran to his room to pack.
"Oh, this is gonna be great! I have to show him how to get into the vents." Clint laughed. They would be great friends.
"I am going to have to figure out how you keep getting in there. You've given everyone in the tower a heart attack at least three times. And April fools day is hell with you around." Steve laughed, Natasha nodding in agreement.
"Wow. Do not give sherlock any ideas. I've woken up with an entire cow brain right in front of my face on  ore than one occasion." John sighed.
"Thanks for the idea!" Clint laughed, running in the derection sherlock went, most likely to exstainge prank ideas.
"We are going to have to separate those two." Natasha sighed.
"Definitely." Steve sighed.
"Oh, and, fair warning, sherlock has a habit of drugging people's drinks. I've passed out seconds after finishing my tea at least fifty times now." Josh warned. Bruce facepalmed.
"Fury.... is this a good idea?" Bruce asked, raising an eyebrow.
"Unfortunately." Fury replied. John shook his head and went to his own room to pack. This was going to be a long trip.
