So this is a story I've thought about writing for a few years now and seeing as I'm re-watching all the films in preparation for Infinity War I thought that I might as well use that as an excuse to really start on this story. So have fun I've got some stories planned that I can't wait to tell, and yes this will cover the MCU as a whole not just The Avengers. I want to try and upload a new chapter every week but a can be quite busy sometime so if I don't upload on Sunday you can bet there will be a chapter next Sunday. Fell free to give me creative criticisms as well. I'm new to writing so all help is welcome, and no this story won't become abandoned. Enjoy!

Normally Privet Drive doesn't normally see any interesting visitors. The last time anyone interesting visited was 13 years ago when a group of three people dropped off a child at the Dursley's house, not that anyone saw them. So, to see a tall, black man walk down the street in an all-black outfit consisting of a trench coat, tactical suit, and eye-patch turned a few heads. Said man was seemed to be walking with a purpose towards the same house those three-people visited 13 years ago.

As he got closer to the house he saw a 14, almost 15, year old boy with black, messy hair leaving the Dursley's house with his head down trying not to draw any attention to himself, for good reason the man thought. Just as the teen past the man he heard "Mr. Potter just the wizard I was looking for". Harry Potter stopped suddenly, turned to look at the man from his left side as he slowly drew his wand out of the holster on his right arm. "I'm not here to fight you Mr. Potter, so please don't cause a scene."

"Who are you?"

"Nick Fury, Director of S.H.I.E.L.D"

"What do you want?"

"I need your help Mr. Potter."

"My help? With what?"

"He calls himself Loki"

Harry looked at him with an unbelieving look as he questioned "As in the Norse god?"

"The very same." As he said this Fury took a file out of his coat and pasted it to him. "I'd rather not include you in this, but I don't have another choice. Loki seems to use some sort of magic, not like yours, but I figured I'd rather have you helping me with this."

"Why ask me then? I mean why not Dumbledore? Or another wizard or witch with more experience than me with magic? I mean I'm only just starting my 5th year in two months"

"Because I trust you to do the right thing, most wizards don't care what happen to muggles or they would catch too much attention. Plus, I've heard all about your life in school, I think you've had enough experience."

"I mean sure I've done things that other people my age haven't done but it's always been with help from Hermione, Dumbledore or it's pure luck that's helped me though, not my knowledge of magic." Harry seemed to be getting frustrated that he wasn't getting the complete answer best finish this now. Better to leave him frustrated then continue to do so, at least then there's a chance he would agree just to find out the rest

"I think you don't give yourself enough credit Mr. Potter. We both know that you know more then you're letting on. You'd need to, to survive the Triwizard Tournament." Harry looked down at the file with an interested expression before slowly reaching out to take it from Fury. With that done Fury nods and turns around heading back the way he came calling over his shoulder, "Everything you need to know is in that file, I'll have someone come pick you up tomorrow if you're in. Now if you excuse me I have a solider to speak to."

With that Harry looked at Fury with a confused expression before looking down at the file and turned to go back to the Dursley's, his original goal long forgotten.

As Bobbi looked up at the apartment building in front of her she thought back to the file she was given. The file was on a person, an alien and an AI. When Bobbi initially read their file, she was confused to say the least, the human in their group didn't have any records to speak of, he just didn't exist. It was theorized by their AI, who apparently goes by the name Cortana, that they could have been displaced by something called a 'slipspace portal'. She stopped reading after that, she couldn't even begin to understand the science behind it. The funny thing is until recently Bobbi would have Bobbi would have laughed it off until she was shown proof otherwise, but with Norse gods trashing up towns and heroes from the 40s being found alive and well Bobbi was more inclined to believe anything could be possible. The fact that she was going to meet an alien didn't even phase her.

They were moved here after they dropped out of nowhere and questioned by S.H.I.E.L.D. The questioning didn't tell them much of anything that would be useful to them now, just lots of information about where they were from and who they were. When S.H.I.E.L.D moved them here it was with the intension of finding them a way home then sending them on their way but, sadly, things had changed and now Bobbi was being sent to ask them for help against some madman called Loki.

Loki. That name caused Bobbi to fell hatred like she had never felt before. It wasn't that he took Clint, she remembered one time where he disappeared for a year after his cover being blown. No, it was the fact that Loki seemed to have control over Clint making him one of his own lapdogs, just another goon of him to use the throw away when his usefulness ran its course, that pissed Bobbi off more than anything. Her husband was so much more.

So here she was helping Fury gather a team to stop Loki. She was sure Natasha was in on this too, Bobbi would be surprised if she wasn't. Bobbi knew Natasha felt like she owned Clint she had said so herself, when she promised to always have his back after he brought her to S.H.I.E.L.D. Since then Natasha had been added to Strike Team Delta, Bobbi and Clint's team, and was never seen without either of them, although she did get along with Phil, Maria and Fury. As well as anyone can get along with Fury anyway.

Deciding to stop her internal monologuing Bobbi went and made her way up to S.H.I.E.L.D apartment 117. According to the agents that escorted the group to the apartment this seemed to be some sort of inside joke between them as evidenced by the way that Cortana laughed and the alien, who preferred to be called The Arbiter instead of using an actual name, seemed to wear what the agents theorized was a smirk on his face. Apparently, the agents had a tough time reading his facial expressions as he had four mandibles in place of a mouth.

When Bobbi knocked on the door she didn't exactly know what to expect. Would The Arbiter answer? Unlikely, while the group didn't seem to come from around here they definitely must have realized that an alien answering the door wasn't a common place thing around here, and seeing as an AI can't really open a door that's not attached to a computer, as far as Bobbi was aware of, she could only assume that the human of their group who, like The Arbiter, insisted on being call Master Chief instead of an actual name, would be the one to answer the door.

Bobbi was proven right when the door in front of her opened reveling a man whose head was almost completely eclipsed by the top of the door frame. Of course, Bobbi was told that he stood at about seven-foot-tall but seeing in person was another thing entirely. Trying not to show her surprise she decided to get right to business "Good evening" she started "am I correct in assuming that you're Master Chief?"

He seemed to study her for a second probably trying to decide her intensions before replying with a rough "who's asking?"

"S.H.I.E.L.D" That was all Bobbi needed to say before he seemed to take a less defensive stance before opening the invitingly. Without any more words said she walked past him and into the apartment. It wasn't a big apartment, about the standard sized living room with 3 doorways, which she assumed were for the 2 bedrooms and bathroom, off to the left with only a breakfast bar separating the kitchen from the living room on the right. Quite homely she had to admit to herself.

"Spartan?" she heard an alien voice, who she assumed must be The Arbiter call out, call out "who was it?"

"S.H.I.E.L.D" Master Chief replied with. Without any other explanation needed The Arbiter walked out of the bathroom holding some sort of computer chip in one of his hands. For the second time today, Bobbi had to try and hide her surprise at seeing The Arbiter, she didn't really know what to expect she didn't read everything S.H.I.E.L.D gave her on them that would have taken up too much time, time they didn't have.

When Master Chief went over to take the computer chip from The Arbiter she that he stands just a bit higher them Master Chief, somewhere between 7' 9" to 7' 11" if she had to guess. His legs looked like someone took the legs off a deer, twisted the feet round and put them on back to front, and the foot itself was just too long toes and his long arms hand hands with only four fingers on them. He also seemed to wear some sort of amour. While, from the picture Bobbi had seen of it, Master Chief's amour looked like a militarized weaponless version of an Ironman suit, The Arbiter's looked nothing like it. It looked older, almost like some sort of knight amour with an open helmet and if Bobbi didn't know any different she would have said it was made from gold. Master Chief though wasn't in his amour, S.H.I.E.L.D had confiscated it for security reasons, mainly so no undesirables were able to get their hands on it, The Arbiter didn't have his amour confiscated because human clothes don't fit him.

"How can we help you agent?" Startled out of her study of The Arbiter Bobbi noticed the computer chip that Master Chief had taken off the Arbiter was now projecting a blue woman on top of it. Bobbi could only assume this was the AI Cortana, the third member of this group.

"S.H.I.E.L.D needs your help" Bobbi answered, "I know this wasn't part of the deal originally, but things have changed." As Bobbi continued she handed Master Chief a S.H.I.E.L.D tablet with all the information S.H.I.E.L.D had on Loki, Asgardians, and the group of people they were calling in to help them. Well not everything, somethings would need to be explained in person. "Fury has also been able to receive your armour from S.H.I.E.L.D lock up as well" that seemed to relieve Master Chief as for the barest of moments Bobbi saw his shoulders slump in relief, for a split-second Bobbi wondered if his armour meant more to him than just something he wore as a soldier.

"Chief, Arbiter" Cortana said with what sounded like repressed angry or fear, Bobbi couldn't tell. "This is big, we can't ignore this. I know we just wanted to get home and worry about this place as little as possible, but we can't ignore this, this is too big to ignore."

Chief looked over at the tablet that Cortana was downloading all the information from, how had Bobbi not seen she was doing that? she was getting sloppy and read what Cortana had brought up on the screen, The Arbiter copying his actions. After a few minutes of them reading the tablet, what Bobbi couldn't say, both Chief and The Arbiter looked up to each other before The Arbiter nodded at Chief. Master Chief then turned to Bobbi.

"We're in."

Harry didn't know how long he had been staring at the file, he just knew he didn't like what was in it.

The story about a Norse god breaking into a secret government facility using a cube, apparently called the Tesseract, from space then stealing said cube while using some form of the imperius curse to control some government agents, including one of their best agents who prefers to use bow and arrows, then makes his escape disappearing off into the night.

While the word impossible wasn't really a word Harry had used since he discovered he was a wizard, he was tempted to use it now. That is if it wasn't of the pile of evidence prove that, yes, this did actually happen, and Harry wasn't having some weird dream in place of his usual nightmares, and now apparently, he was being asked to help S.H.I.E.L.D track down this Loki and stop whatever plan he's put together.

Harry still wasn't convinced he was the right person for the job. He's only had 4 years of schooling, sure he. earned some more advanced spells last year because of the Tri-wizard Tournament but he still didn't have the years of experience that Dumbledore had. But then at the end of the day, did that really matter? Harry already knew his answer, he had since Director Fury had asked him, he was just being stubborn at this point. It was just like Hermione said, he had 'a saving people thing'. Plus, he wouldn't have to deal with the Dursleys for a few weeks.

Hermione, that made him stop a second. He'd have to tell her something. He couldn't exactly just leave and not tell her anything, especially as she was the only one really talking to him this summer and not just telling the bare bones of what was going on and leaving out everything happening in the wizarding world. Just as he was thinking about what he would say to Hermione, Hedwig came through the window with a letter attached to her leg.

As Harry took the letter off Hedwig he noticed Hermione's well-formed and tidy writing all over the paper, which wasn't that much of a surprise, he wasn't expecting anything from Ron, he'd already sent his one letter today. As Harry read the letter he felt instantly relieved. Hermione was going to New York this summer with her family and would be out of reach of owl mail for the next week, Harry was just thankful he didn't have to send an awkward letter to Hermione. He didn't know if he could send her a letter explaining he was leaving to fight a Norse god and wouldn't be reachable for a while. He didn't think she would take that well.

So, with that taken care of Harry started to pack everything he might need to save the world, it felt like that was going to be something he was going to say more in the future. He packed his invisibility cloak, some of his nicer clothes he was able to get without the Dursleys knowing, thank you Hermione, his broom and his wand. Now all he had to do was his Aunt and Uncle know he was leaving for a week or two. As Harry walked down the stairs a sudden cloud of worry drifted into his mind.

How was he supposed to help when he can't do magic outside of school?
