Hello, I know this says that it's a crossover with the Avengers and Agents of S.H.I.E.L.D. but it is so much more than that. When I first came up with this in my head over four years ago it was just going to be a Agents of S.H.I.E.L.D. fanfiction that was never going to see the light of day. No one but me was going to be reading it like all of my older fanfiction works that I am in the process of rewriting right now and am going to be posting them here and there. But anyway as I wrote I started to have ideas like "wouldn't it be cool if (insert character here) interacted with them?". Or "it would be sooo cool if these characters went (insert location here)". So as I wrote it all down I added things to what I have come to call "My MCU". Like the introduction of a few characters that Marvel/Disney don't own yet or quite possibly ever will. I chose Avengers to be the crossover with Agents of S.H.I.E.L.D. because that was the closest thing to an MCU option they had and this story is one big ass crossover. So sorry for any confusion and yes I know that many people will hate the changes that I have made but I hope that the changes that I have made were in the best interest of the story and not just because I wanted those characters to do those things or act that way. Anyway, I hope you enjoy this long ride because with what I have written so far in this story and where the story is going it's going to be one hell of a ride.

Chapter 1

Agents of S.H.I.E.L.D. "Nothing Personal"

My name is Charles David Hall and this is my story. I was born different than most. I have powers that ordinary humans do not have and right now I was about to use one of them. Because there was a beautiful lady trying to get away from some guys and they're getting a little rough. Like breaking the front window of the police car that she was in trying to get away from them.

"I think that the lady doesn't want to go with you," I said grabbing the guy on the hood of the car and using super strength throwing him fifty feet into the air and landing on the other guy. I went to the door of the car. "Hello, there pretty lady. Would you like a hand?" I asked her through the door. "Who are you?" she asked getting out of the car. "In this situation, you can call me S-Class," I said as she made sure she had her backpack and everything that was inside it.

"S-Class? What the hell is that about?" she asked as the two guys started to get up. "Later sleeping ugly and uglier is getting up," I said. "I got to get to the airfield," she said starting to run. "Well, I think it would be quicker if we go my way," I said grabbing her hand and teleporting the both of us to the airfield. "Skye. How'd you do that? Who is this guy? Where is Ward?" were some of the questions that I heard when we teleported to the airfield.

"Coulson? Agent Phil Coulson is that you?" I asked. "How do you know him?" asked a woman I recognized immediately as Agent Maria Hill. "That's going to be hard to explain unless you have a biochemist with you," I said. "As luck would have it we do but we need to get out of here like five minutes ago. Ward is HYDRA and he and Mike are probably on their way here to figure out where we went and HOW WE GOT HERE." the woman that I saved said. That last bit was to me.

Later after we took off the biochemist that was named Jemma Simmons started to take my blood as I asked them to do. "Why would taking your blood help you explain who you are?" Agent Hill asked. "Because of what she's about to find out in 5, 4, 3, 2…" I said counting down to her discovery. "Oh my god you're not human," Jemma said to me.

"You're right. My name is Charles David Hall or just David, but in the field, I go by S-Class and I'm a mutant." I said. "What does that mean?" Skye (the woman that I saved earlier) said. "It means that I was born into a separate species that sprang from humans. Our scientific name is Homo Sapiens Superior. We really only have one gene different the X-Gene that grants those who have it special powers like super strength, teleportation, mind reading and so much more." I explained. "I've never heard of such a thing," Jemma said. "Well, to be honest, I would have been surprised if you had. Because from what I've seen of this universe they do not exist. Not yet anyway." I said. "This 'universe'?" Agent Hill said.

"Yes. Several years ago I was altered. The power that I was born with was in a way taken away and I was given new powers to replace my old. And I'm sure you did a scan for weapons and discovered that my entire skeleton has been coated with metal." I said. "Actually we didn't. Fitz, scan him." Agent Coulson said to his technical mechanics expert. "Yes, sir." he said as he grabbed a machine and started to scan me. "Before you finish I don't want you to panic," I said as I drew out my metal claws with a snikt sound. "You have claws?" Skye said. "Yup, the metal is called adamantium the hardest metal in many universes. I don't even know if it exists in this one" I said retracting my claws.

"Anyway, when this happened I had very little to no control of my new powers. One of which is to create a dimensional wormhole that allows me to travel the Omniverse." I said. "The Omniverse?" Skye asked. "Yes, the Omniverse. We are all from the Marvel Multiverse which is a collection of other universes that are connected to the seed universe from which the Marvel Multiverse sprang. Then there is the Megaverse which is a collection of multiverse-related by the similar origins. In our case, it's comic books. Our seed universe was based off the comic book company called Timely Comics later renamed Marvel Comics. And then there is the Omniverse which is everything. Every Multiverse and every Megaverse.

"That's how I know the both of you I've run into several Agent Maria Hills and I'm constantly running into Agent Phil Coulson of S.H.I.E.L.D. though what the initials stand for are always changing. What are they here?" I asked. "The Strategic Homeland Intervention Enforcement and Logistics Division." Agent Coulson said to me sadly. "Yeah, I heard that S.H.I.E.L.D. was infiltrated by HYDRA if there is anything that I could do to help you I'm yours," I said. "Really? Why?" Agent Hill asked. "Because I owe a Phil Coulson my life. And I'll be damn if I let one go if he needs my help." I said.

"Can you help me find one of my friends?" Coulson asked. "Sure who is it?" I asked. "Her name is Melinda May. Do you know who she is?" Coulson asked. "No. I've never met some of you before. Show me what she looks like." I said and he brought me several pictures of Melinda May. I sat down and concentrated on the woman in the picture. It took me a minute but I found her.

"She just left a cemetery. Wait a minute there is a gravestone with your name on it Coulson." I said looking at Coulson. "Yeah that is a long story but how can you know that she's there?" Coulson asked me. "Long story short I can read people's minds and send astral projections. And I'm in her mind right now. And I think she knows I'm there." I said shocked. "What do you mean?" Skye asked me. "She's putting up mental firewalls locking me out of portions of her mind. For a human, she's pretty good." I said.

"Okay, can you tell her to stay in that area?" Coulson asked. "Yeah but I think it would come better from you," I said connecting their minds. "I don't know who you are or how you're in my mind but you need to get the hell out." May thought to us. "May is that you?" Coulson asked out loud. "Yes, I've connected your minds. But a word for the wise you don't have to physically talk Coulson." I said to the both of them and out loud for the rest of the room to hear. "It's my first time talking like this, forgive me. May you need to stay where you are and stay safe we are on our way there. AND IF YOU RUN INTO WARD RUN HE'S HYDRA." Coulson thought to her.

"He's HYDRA?" she asked. "Yeah, I know. We need all of us safe and hidden. We're on our way. Stay safe." Coulson said. "What about our base?" May asked. "Long story and it involves Hill. She told me that you two talked about TAHITI. Listen we'll talk about everything when we get the bus on its way to another one of Fury's secret bases." he said making arrangements to meet back up with her.

"Thank you. I hate to keep you from trying to get back home any longer but we can really use your help." Coulson said to me. "Coulson I said that I didn't have control over my powers in the beginning, but I never said I was trying to go back. I've been back there several times. But for some reason, I keep searching the Omniverse; for a while now. It's like I'm searching for something. But I have no idea what. But I think it's here in this universe. I can't put my finger on it." I said looking around the room on the plane and landing on Skye. "But I think I'm closer to it than I ever been before," I said still looking at Skye.

"So this is where you ran off too," I said walking into the room where Skye was. "Why are YOU the one that finds me?" she said to the ceiling. "So I was right, you don't want to have anything to do with me," I said to her. "It's not that," she said looking into my eyes to make sure that I could see that she wasn't lying.

"Then why did you hide in the cargo hold with...I believe the cars name is Lola?" I said to her. "It's just what you said about being close to what you were looking for. I'm not ready to start anything new," she said to me. "Did you think that I was talking about you when I said that I was looking for something?" I asked. "Weren't you?" she asked me looking puzzled.

"No," I said with a small smile. "Now I feel stupid," she said going red in the face. "Don't. Truth is that when I started traveling the Omniverse I would have said that what you thought I was looking for IS what I was looking for. And you would have met the qualifications for everything that I was looking for. You are beautiful and smart, tough as nails and soft as a kitten and you're feisty as hell. I would have been all over you." I said. "What happened?" she asked.

"Well, where I come from women like you look down on mutants. Because their children may be mutant and racial equality isn't very big there. I thought it would be easier to fall in love without all that over my head. But then I started fighting alongside not only other universes versions of the X-MEN, a team of mutants fighting for equality. But THE FANTASTIC FOUR, THE GUARDIANS OF THE GALAXY, SPIDER-MAN, THE AVENGERS and even Agent Phil Coulson of S.H.I.E.L.D. and that among other things started to change what I wanted and what I was looking for." I said. "A.C. can do that," she said calling Phil Coulson by a nickname that she had given him.

"A.C.? I like that. Now I want to know why you don't want to start anything new." I said to her. "Why do you want to know that?" she asked looking a little defensive. "I graduated college with the oddest assortment of Majors and Minors. Double Minor in Cryptozoology and Technical Mechanics, and a Double Major in Paleontology and Psychology. My psychologist side wants to know what could've happened to you to make you say that. And then there is the other side of me that doesn't want to blow this because over last twenty minutes I've found it easier to talk to you than many in my home universe so kudos." I said giving her a smile and thumbs-up.

She giggled. "A few months ago I broke up with a longtime boyfriend who was selling information to the highest bidder and the last guy I liked turned out to be HYDRA," she said looking sad. "Ah, so it's all your fault. I mean the guy selling information must have been asking all kinds of questions and then there's the HYDRA guy. HYDRA is evil to the bone in every universe. So you must be the biggest idiot I've ever met." I said. "Why are you saying that just because they were scum doesn't mean that I'm an idiot for falling for them," she said angrily.

"Exactly. Don't blame yourself for them being the biggest morons in the kingdom of morons." I said smiling at her. She smiled. "I see what you did there," she said. "Thanks, I try," I said with mock humility. "I see what you mean I've never warmed up to anyone this fast," she said with a smile.

"Thanks. And as for the other thing about starting something new. My three friends might want to throw there two cents in." I said to her. "Three friends?" she asked confused. "Fate. Destiny. And God. When we think that we CAN'T handle or CAN'T do something. One of, if not all of these three friends of mine throws exactly that in our faces to show that we CAN." I said to her. "I'll keep that in mind," she said starting to smile. And we talked and laughed all night.
