AN: I love all the positive reviews on the Prologue. This is my second attempt at a fanfiction and my first at a crossover. As a reminder I own nothing Harry potter is owned by JK Rowling Marvel and it characters are owned by Marvel which in turn is Owned by Disney
The first thing Harry was aware of when he woke up was a series of explosions. His instincts from the war took over and he jumped up and looked around. He saw soldiers jumping out of vehicles that were being blown up, only to be shot. As he slowly made his way towards the commotion to see if he could help, he saw a man in an expensive suit getting out of one of the only remaining vehicles and running for cover behind a rock. Harry ran to him. As he reached him, he saw him pull out a phone. It was too little too late as a missile landed beside them. Harry attempted to throw up a shield using his magic, but he was too disoriented from his landing, causing them to just barely miss the explosion. Both of them blacked out.
Slowly waking up, Harry found himself in a cave with two other men. One of them was the man from earlier, who now appeared to have wires running out of his chest; the other he had not seen before.
"Did anyone get the number of the truck that hit me?"
The other man laughed. "Good to see you awake. I am Yinsen. I bandaged your injuries for you while you were out." Harry studied the man for a moment before nodding. "I appreciate that .my name is Harry. How is our friend there?" he responded, gesturing towards the man from earlier. Yinsen seemed to study him for a moment. "Tony is well. There was much shrapnel in his chest.. I removed what I could, but was unable to reach the rest. I placed an electromagnet in his chest to keep it from reaching his heart." In the middle of the explanation, Tony woke up and Yinsen had to stop him from removing the wires.
Soon after, several men entered the room. One approached stepped forward and began speaking in another language. Yinsen translated for Tony; The men wanted Tony to build them his latest missile. He refused, but they dragged him away. Harry could hear them torturing him. When they brought him back, he had agreed to build it. After receiving all the materials he needed, he began building. Over the next few days, Harry realized fairly quickly that it was not actually a missile that he was building.
"Tony… what are you building? It doesn't look like a missile." Harry inquired. Tony looked up as he snapped the last piece into place. "It's a miniaturized arc reactor. We have a big one of these powering my facility in Miami. This one is to get me free from the battery in my chest after that we get out of here." Harry nodded, studying the device as Tony turned on the liquid nitrogen. Once reaching the device, it lit up. "It feels like my magic."
Over the few weeks since they had been together, they came to know one another and Harry explained about his magic. Normally, he would just apparate them out, however, something appeared to be keeping them in. All of his other spells worked normally, but they couldn't apparate or portkey out. "Interesting. That's something to test once we get back to my lab… once we are free."
After swapping out the car battery for the Arc Reactor, Tony pulled out the plans he had drawn up. "This suit is our ticket out. Once built we will be able to use it to escape. With this and your magic, Harry, we can get far enough away to eventually reach help." Nodding. they immediately got to work building. Harry who had very limited experience with technology outside of the odd engineering classes he picked up here and there over the last two hundred years, was very little help so he just dismantled what he could and left the construction to Tony and Yinsen.
It took several weeks, but finally the suit was complete however as they started booting up the suit things went pear shaped. Harry was sitting at the console assisting with the boot up process, as he was decent when it came to programming. After the initial charge was killed thanks to explosives, they placed one on the door. Yinsen went running out, yelling about getting them more time, picking up a gun and running up the passage way shooting.
It took several minutes, but finally the boot up process was complete. He nodded to Tony. "Alright, now remember the plan. You go first and I'll bring up the rear. Once we're outside, fly us away and we'll make our way to safety," Harry explained. Nodding as much as he could in the suit, Tony reached up, dropping the faceplate. They began their escape. Tony took out many of the armed guards with Harry taking out the ones left behind.
Eventually they came upon an injured Yinsen. Harry was quick to rush over. "Hold still let me heal you." Yinsen was quick to steady his hand, "No, no, this was my plan all along. I am going to be with my family they were killed long ago and now I will get to see them again." The two were not happy about his decision, but understood and honored it, nonetheless. After staying with him till he drew his final breath, they got up and continued their path outside where they were attacked. Allowing Tony to deal with the ground troops Harry apparated up behind the men manning the turrets taking them out quickly.
Returning to Tony's side, he activated the rocket packs in the feet of the suit and they flew up and away. Coming to a crash landing in the sand, they laughed. "Well for a test run, that went pretty well," was Tony's response. Helping Tony out of the pit he had ended up in, they began their trek through the desert. What seemed like hours later, they heard a chopper passing overhead. They turned and waved their hands to get its attention. it landed and a man climbed out approaching Tony. "How was that Funvee now? Huh, Tony?" He asked half joking before turning to look at Harry. "And who might you be?" Tony was quick to interrupt. "This is Harry he's part of the reason I am alive and he's coming with us." Gesturing to the man, "Harry this is Rhodey." Extending his hand, he shook hands with Rhodey before they climbed onto the chopper.
It was several days later that they arrived back in Miami after being examined several times over by doctors. During this time Tony had Jarvis work on fabricating an identity for Harry. Stepping off the military transport that brought them to the US, Tony's assistant approached. "Why Miss. Potts, are those tears I see? crying over your lost boss?" Tony asked in what Harry assumed was his typical fashion. Pepper laughed, "no, just at the prospect of having to find a new job." She extended her hand to Harry, "Hi, I'm Pepper, who are you?" Taking the outstretched hand Harry shook it "Harry Potter I escaped alongside this one," he said gesturing towards Tony.
Happy, who was standing in the background, gestured to the car "we must be going Mr. Stark. have to get you to a hospital to be checked out," Tony shook his head in response to this. "Actually, Happy bring me to Stark Industries. Pepper call a press conference, I have something that needs to be said… but first a cheeseburger," turning to Harry "you like cheeseburgers right Harry?" Harry just laughed and nodded as they got into the car.
After stopping at Burger King, they arrived at Stark Industries, where Tony gave what was probably one of the most unorthodox press conferences ever held. He announced he was shutting down the weapons manufacturing section of Stark Industries until further notice.
Arriving back at Tony's house he set Harry up inside a room before dragging him down to his lab. "Okay Gandalf, let me see the full extent of these powers of yours." Tony gestured to a target range in front of him. Harry started off slowly with the basic shielding charms before moving into offensive spells such as stunners and disarming charms. "Before I cast these next three spells where I come from these spells are forbidden so I try to avoid them whenever possible. only two I can demonstrate as the third only affects the mind." Gesturing he cast the killing curse and the torture curse. "The green spell kills instantly every time while the red one causes the being its being cast on to feel immense pain. The final spell is the mind control curse provided ones will is strong enough it can be resisted."
Tony stared shocked, unsure what to say before smiling. "Jarvis did you get those readings?" Jarvis replied in the affirmative "I did sir," Tony nodded before turning to Harry "once I build a new one of these," he said gesturing to the Arc Reactor in his chest "I'm designing new suits; one for me and one for you. Though yours will be more about protection than about weapons as your range of spells will handle nicely as weapons. I'm thinking of more of something to help your spells go further and act as a focus." Harry nodded "I am going to have to turn you down, Tony I brought something from my old dimension that will provide plenty of protection." Reaching into his backpack Harry pulled out his dragon-basilisk hide leather jacket and pants "this jacket and pants are made up from some of the most powerful protective skins of my old dimension it's a mix of basilisk and dragon hide sewn together with acromantula silk. Nothing can penetrate either of them and once I put on the hood from the jacket my identity is hidden as well." Tony nodded before moving to his project table to start.
AN: The marvel universe won't start changing until the end of Iron Man most of the events of Iron Man will follow canon from the MCU until the battle with Obidiah from there things will be very AU.
AN 2: To answer the burning question in review I haven't decided on pairings it won't be slash. I have a few thoughts on who he will be with but nothing concrete
