It's Time To Live Your Life

Disclaimer - This is a Harry Potter/Avengers Crossover Again! I love this crossover and it seems you lot do to! I own nothing apart from the plot line!

Authors Note - New Story! You guys have inspired me to write more and more... Although some of my stories haven't been updated in a while... But I just have so many idea's!

Just so people know, Tony is about 10 years younger in this! I'm not too sure the exact age but I'm going to go with 33 and I know he's quite a lot older than Harry, I have some plans and if they don't work out I'm going to have to rearrange a few things and change the pairing from Harry/Tony to something else without having to change my story completely. If you have any idea on how this could happen, let me know. And just so people know, this isn't a no magic fic, it just so happens harry doesn't show or know about his magic yet, which will be explained some point in the future. So I have a few ideas about it.

Chapter One

A group of teenagers stood crowded around an older female, some listening to what she had to say others messing around and goofing off with each other not caring what their teacher was trying to teach them. One person stood apart from the group, a young man standing in front of the giant Arc Reactor that was stationed at the Expo. He had his shoulder bag hanging to the side of him, open due to the mass amount of paper that seemed to be in there not counting the note pad and pen in his hands. He was non-stop writing almost, viewing the Arc Reactor as if it was telling him everything it knew. Two other people were watching the group as well as the young man. Well, the woman was busy glancing over at the group as well as tapping on her tablet to notice that the young man wasn't with his group anymore and he didn't seem the least bit bothered. The man next to her was gazing quizzically at the boy as if trying to read his mind and find out why he wasn't with his group. This young man was Harry Potter and he was 16 but turning 17 in a week's time.

Clearing his throat, Tony, one of the two people watching, gained his secretary's attention, Pepper, as he gestured over to the young man. She took a look, frowned slightly before turning her attention back to the Stark Pad. "What Tony? I'm incredibly busy and if you hadn't dragged me here just so you could see a bunch of kids awe over you and your inventions, I'd have done this by now." she didn't seem the least bit interested and Tony frowned over at her but didn't comment on it.

"What I want Pepper, is to go over there and see if I can't help the kid with anything. Which I'm going to do, so I just thought I'd warn you before you have a go at me for wandering away from you." Without waiting for an answer, he turned on his heel and walked over to the kid, lifting his trademark sunglasses up and placing them on top of his head, placing what he calls his 'Fan Smile' on his face.

Standing next to him, the kid didn't seem to glance or acknowledge his presence so it gave Tony the opportune time to see what he was doing. On the page he was writing on and the other in the notebook and his bag from what he could see, all held calculations and speculation to some of the things in the Expo. Eye's widening when he realized the kid could understand everything he was writing down and trying to figure out how the Arc Reactor worked he knew he had to introduce himself.

"Hey, Kid, you need any help?" he tried to make it sounds as casual as possible, hoping the kid wasn't going to scream and beg for an autograph. He got his wish, because as the kid glanced up a glint went across his eyes as he realized who was stood next to him but didn't give any other reaction other than a small smile.

"Hello Mister Stark, pleasure to meet you. I don't particularly need any help unless you could tell me whether or not I'm right in what I've worked out so far." His voice was soft and had a whimsical quality to it that made Tony think that while the teen knew who he was and was happy to meet him, he knew that screaming or yelling wouldn't get him anywhere.

"Well, I'm pretty sure I can help you with that. What are you trying to work out?" he already had a very good guess on what that was but he wanted the kid to tell him, along with his name as he realized he still didn't know it.

Giving a soft smile up at the celebrity, he showed him the top sheet of his note pad and softly explained it to him. "I'm trying to figure out how the Arc reactor that's in your chest actually works, as the big one in front of me, if you did it the same way but smaller, would basically kill you as some of the parts of it wouldn't be compatible with your body and try and poison you." The way he said it showed Tony that he knew what he was talking about and not just fluking his way through the conversation.

"Your right Kid. Sorry, I can't keep calling you Kid, what's your name?" Tony being Tony, bluntly asked the kid and he didn't get an offended look on his face or anything, just continued to smile at him only it got slightly bigger.

"It's Harry, sir. Harry Potter." The way he quietened on his last name made Tony slightly suspicious but left it as he knew he wasn't lying but it looked as though he didn't particularly like his name. Nodding, his face never showing his thoughts, Tony nodded towards Harry's notes, silently asking to see them.

"I have quite a few. I've figure out how every exhibit works and mass etc. And this is the last one and I'm determined to find out how you did it. If you wanted to look at all of the ones I've written on the Arc Reactor, we may need more than 2 pairs of hands, or a place to spread them out if you wanted to be able to read them in any order." Harry shuffled through his bag, pulling out the notes he had on the Reactor and looked towards Tony as he finished what he was saying only to be surprised when he 'plopped' down on the floor with ease and looked up expectantly at him, a cheeky grin on his face that made Harry's cheek warm up slightly. Following his example, he sat his bag down first before sitting himself and started to spread out his research out in order.

Leaning back when done, he took the time to observe the billionaire as he read through his notes. His cheeks were still slightly warm from the grin that Tony had sent him and thinking about the man in question made them even more warm, even though he didn't know exactly why.

"Wow Kid, you've got to be really smart to understand all of what you've wrote down and I know for a fact that unless you knew the inner working of everything that goes into the Reactor, you couldn't get as far as you have. None of this is on the internet, I had JARVIS make sure none of it was on the internet, so you couldn't have learnt it from there." Tony looked very impressed and Harry smiled up at him, because even sitting down, Tony was quite a bit taller than him.

"Thanks! I'm almost there I think in figuring out why the arc reactor can work inside your body, because to power it you'd have to actually have something like 'Palladium' or something similar, but the problem with that is it would keep you alive with your Reactor but it would eventually kill you by poising your blood and since I don't see any black or blue lines coming from underneath your shirt, my guess is you found something alternative that works as well but better because it's perfectly safe." Waiting for the nod to continue and that he was right, Harry took a deep breath and stared at all the pieces of paper in front of him. Most of them were of every single element in the periodic table of element, and what each doesn't, how it reacts and how it's structured, drawn out in a diagram.

"I've gone through every single element there is out there to see what would react best with the reactor, let it still keep you alive without poising you. But there isn't one. Not a known one anyway, but you obviously found a way to do it! So, then I looked at the element again and looked at which ones had the qualities needed, separately, so they didn't need to be all in one element. And the only three elements that I found would come anywhere close to helping, not counting the Palladium chips, were Hydrogen, Argon and Magnesium (A/N I have no clue, I'm just making this up!). But combining these three together just created an explosion, therefor there not any good for your body. So I kept thinking. You need these three somehow not combined but together for your Reactor to work perfectly and it dawned on me. What if the new element isn't created by combining those three element but it can be split up into those three elements? And that's my final clue to you creating a new element somehow that when broken down, those three are made with some excess of Oxygen for some reason. That new element is what is in your Arc Reactor now isn't it, sir? Have I got it right?"

All the way through Harry explaining his though process, Tony's eye's brows couldn't have gotten any higher because everything he had said, was right. All of it. How he'd created or 'found' as it should be, a new element and if broken down it created Hydrogen, Argon and Magnesium.

Harry finished his speech and looked expectantly at Tony, brows burrowed slightly hoping not to hear he was wrong or for Tony to laugh at him.

"Harry, just how smart are you? I mean really, you figured out what took me months to figure out and you've only been here a few hours!" his question was serious and Harry could tell even though his slightly joking comment at the end was genuine too.

"Err... Last time I checked my IQ was 139 but that was a couple of years ago and I haven't bothered to have myself tested to see what it is now. When you have a photographic memory, you don't really need to check how smart you are. You know you remember things and that's all you need to know... To me anyway." Harry's answer was sheepish but his face showed little to no emotion as he watched Tony's face for what he thought.

"139? Mines only 134... You have a higher IQ than me? Jeeze kid I knew you were smart but not that smart! Do you want to come work for me? Seriously, come work for me! Be a part of my research teach, the Avengers research team! I'd give you anything, pay you what you wanted! But with you on our team we could do so much for everyone! Although, Pepper might hate having effectively two of me around..." Surprise wasn't enough to call what went across Tony's face and appeared in his voice and then it went straight from that too excited, bouncing on the floor like a toddler getting a sweet, not seeing the slight panic go across the younger person face.

"W-Work for you? On your research team? You have to be joking? Why would you want me to work for you? I'm Harry! Just Harry, nothing more! And it'd be kind of pointless me working for you, when I'm probably gonna be dead soon..." The last part was whispered so quietly that Tony nearly didn't hear it but he couldn't say anything as Harry was starting to panic, even though working for Tony was a one in a life time chance and it was his life's dream he never thought he'd see.

Narrowing his eyes on the black haired youth, he leaned forward and touched his hand lightly, making Harry look him in the eye. "Harry, what do you mean you're probably going to be dead soon?" There was nothing but seriousness in his voice and not being able to look away, Harry knew he wouldn't be able to get out of answering this one.

Breathing in a shaky breath, he let it out again before sighing and breathing once more and answering him.

"I have Cancer..."
