I do not own Harry Potter and Avengers, this is fan fiction.

If Nick Fury ever saw Harry angry this next mission briefing had to be the single worst he ever gave him or Natasha. It had no infiltration, no torturing a dumb thug for information, and most certainly no killing involved. It was a simple request made by one Charles Xavier. He asked him as a show of good will, that they sent Harry to run some tests so that he could learn more about his mutant abilities and potential undiscovered powers.

The reaction from Natasha was not so kind but it was not as angry as Harry's was. She just said that the red haired bimbo wanted another shot at trying to seduce her man. It was an honest mistake, she had no clue that she was actually daring Logan for quite a while now. Harry glared at him and called the entire mission. "Bullshit, you heard me I think they just want to use me as a Guinea pig so they can try and copy my healing factor. Xavier how could I ever forget him."

Nick was speechless, as he had no idea he actually knew Charles Xavier. "It was during one of our concentration camp liberation missions, him and his friend were little kids in one of the concentration camps we attacked. Xavier stole my wallet and tried to run off with it. The little brat was not even sorry he did it. Steve told me to give him the cash and he would replace it later. Steve still owes me for that cash.. He was frozen in ice before he could pay me back that money. $350 dollars and 85 cents.. "

" Be it as it may we want to keep good relations with the X-men and so you are going and you will be going with Widow so that she can get you out if they try to keep you for their own team." Great, just great here he was going to the place his son was living in, but it was not for a much needed father and son get together it was for him to be tested like a frigging lab rat.

As the two got aboard the jet Natasha asked him what he hoped to get by learning more of the healing factor, he already had Logan after all. "Charles is a cripple. He is stuck on that wheelchair for the rest of his life. If he ever figured how to make it possible for him to also have my family's healing factor, he could heal himself and walk again. That is why he accept my son so easily after all, or it is the reason I have come to believe. "

Natasha could see how he would think that, Logan was anything subtle when dealing with an enemy. The damage to the town he fought Victor was proof of that. " Why can't you heal him with your magic? " Natasha clearly wanted to change topics. " Because the bullet moves and there is no scanner on earth that can scan through the adamantium plated around his skull."

"A single scan on a MRI machine could not get a clear enough of a picture as to the location of the bullet.. As I sad the bullets moves. I would need either something that can scan through adamantium and lock on the bullet and then teleport it out of him without taking some of his brain with it. "

" There is no technology on his world that can do all that. I rather have my son keep forgetting about me and his mother, than have him remember our past and dying a minute after. " Natasha could hear the pain in Harry's voice. He really wanted to help his son, he simply did not have the necessary equipment to do it.

The jet landed on the school's hangar and they both got out of it. " Welcome Reaper to my school. I heard a lot about you from our good friend Logan. I am very grateful that you came, and I hope we can help each other out." Harry walked up to him and glared at him. "Can it Charlie I still remember the time you stole my wallet. I save you and your parents from a death camp and how do you say thank you? By stealing my wallet."

Charles Xavier did remember doing that to someone but it was a long time ago. It was true his family was indeed rescued from a death camp, but without money they would not survive long enough to make it to America. "I think you must be mistaken. I was rescued from that camp a long time ago by allies it is impossible you were there. You be an older than I am if you were."

Jean did not tell him he was Logan's father, she just mentioned he had the same healing factor as Logan and Victor. Harry took off his mask now angry that he dared call him a liar. "Ok, I guess we need a little something to jog your memory. Remember how Captain America told me that he would replace all the money I gave you from the wallet you stole?"

"Or do you need another spanking to remind you not to take things that don't belong to you? Just try not to cry and spread snot like you did last time. " Charles did remember him now that he saw his face and he mentioned the spanking he got. Same spanking that Captain America stopped and told him he had reasons for doing what he did.

" I said that you needed to learn to ask for things instead of stealing them. So Charlie mind telling me the truth? Or did we not learn the lesson about not stealing. " Charles looked at him in disbelief as he was sure this was the same man that he did receive all that cash from and it was thanks to that cash they bought their ticket to make it to America.

" 300 dollars was something akin to a small fortune back then, or it was to a scared little boy like I was. I never said this before but I am sorry Mr. Potter for stealing your wallet and I will have you know my family made it to America thanks to that cash. I would be dead if you simply said no. "

Harry could still see him as the little boy he once was. " It took you a long time, but better late than never. I forgive you Charlie. But where is the truth about these so called tests. " Charles Xavier seemed like a massive weight was lifted of his shoulders. "You correctly I do want to learn to copy that ability of the healing factor, but not only for myself but for every mutant that is in need of healing no doctor can provide and to help keep my students alive."

"Ok, then I guess you want to know how it is I got this ability then.. " Harry followed Charles and the others to a small quiet lounge, somewhere where he could sit down. Natasha sat down right next to him.

" A long time ago, there was a secret society of witches and wizards in all the wold. The Magical Nations we called them. I was the most fabled wizard before I could even speak for I survived the single spell that guaranteed death on who ever touched. I was called the boy who lived. "

And so began the long and painful tale on his seven year war against Voldemort and his death eaters. " As a last ditch effort to gain immortality he cast a curse draining all the world of magic and absorbed it into himself, but the thing was I had a piece of his soul in my scar. The curse worked killing all the wizards and witches in the world. But the magic entered me instead of him. He died by his own curse and I was forever changed by it. His soul fragment was also destroyed by the curse. "

Charles sat there silently thinking of what he heard. " The curse and so much magical energy caused you to mutate. It is not unheard of that energy can cause a mutation. But why do you sound like it was something painful? You gained the ability to say young practically forever."

Harry looked at him with a serious look on his face. "Would you be happy to gain this ability if the cost was the life of the one person you loved more than anyone in the world and the lives of your dearest friends?"

Charles Xavier could count the times he was speechless, and here he was asked a question that it was impossible to say yes to. "I see, so that is why you have never told this story before. I am sorry again Mr. Potter for opening such an old wound. But do you have any requests for these exams."

Harry told him he had two requests, one that he be careful on who he granted this healing factor if he did manage to copy it and two that he find a way to remove the bullet from his son's skull. If he did those two things he would allow him to run his tests.

"I already have the means to remove the bullet, but we needed your data to make certain the recovery process was speedy enough as not to cause any lasting damage. We are giving your son a much needed boost to his healing factor. That is why I said, those who needed healing no current medicine could provide. "

The test were painful, and long but after the long series of test the doctor named McCoy or as he was also called beast developed a formula that would give a person a temporary version of his healing factor. Anything permanent would not be a cure it would be a mutagen and that was not something that the good doctor would ever consider making.

"Do you not know anything besides Romeo and Juliet? If you must keep quoting plays try Macbeth, Othello, Hamlet for crying out loud. I can't stand Romeo and Juliet. " Beast was slowly unstrapping him from an analysis machine.

" I do not see what the problem was, it is a beautiful story of romance and true love. What could possibly cause you to hate such a wonderfully romantic play. " Harry began to get dressed and when he was half way through he looked at the good doctor. " There is two facts that made me hate it, the suicide and the fact that that I saw a boy play the part of Juliet. Women were not allowed to act on stage when the play first came out."

He placed his mask last, "I despise discrimination in all forms. That pretty much ruined the play for me, specially since I knew a young lady who knew that script better and could have acted a much more brighter and moving Juliet than he could."

Beast was left nodding his head, "I see so the Reaper really is not one for discrimination after all."

It turns out the reason Xavier had such an amazing level of technology was because a long time ago when he could still walk he helped a young woman who turned out to be the current reigning empress of the most powerful empire in the Galaxy. The Shiar empire provided Xavier will all his current tech and a way for him to talk with her.

He simply called her up, he might look like an old man now, but the empress looked like she was in her mid thirties. "So Charlie need me to do you a favor? Pray tell what could I possibly do to help you this time my love."

Charles told her of the problem and she nearly fell out of her chair laughing so hard. "Seriously Charlie that is basic standard care tech here in my empire, I will have the machine sent to you from one of my nearby outposts. But seriously Charlie you should reconsider that life extension operation. All you have to do is leave earth and agree to be my prince consort. You know I still love you, as much as I know you still love me. "

" If I could solve the discrimination against mutants here I would, but I simply can't abandon these kids. I hope I can solve it and then we can be together again. " the communication channel shut off and she was left wishing he accept her other proposal of annexing the planet to be part of the Empire. Discrimination was a death offense after all. That would solve the problem as quick as possible.

The machine was not only a hand held device but it was smart enough to work on voice commands from all known languages. The operation was as simple as curing a paper cut with this device and the injection made it virtually impossible for the extraction of he bullet having any negative side effects.

Harry and Natasha waited for Logan to recover from the operation. They told Nick the obvious lie that they still were running tests on him. Nick had no way of knowing it was a lie, but he had his own reasons for doing those tests, he missed having two eyes for once and he was planing on using it to revive a frozen hero.

Logan woke up and was feeling better than ever, he walked out of the operating room to the waiting area only to find the surprise of a lifetime. He regained all his lost memories which included the reason he was running towards Harry and hugging him with tears on his face, screaming all the while "Dad, I missed you so much."

Jean, Natasha and the other women around said that it was all worth it to see such a touching scene, the other good news was that Charles Xavier will never have to use the wheelchair again, unless he leaves a hospital for some other reason. The thing that shocked Jean was that he actually looked younger than when he first received the injection.

"The temporary heal factor heals everything much like Reaper, the formula seems to hate discrimination too. " Beast explained as he handed Charles a mirror. He was so happy he was crying." I guess I have a few more years to fix the mutant discrimination problem on my world, before I can rejoin my long missed lover in the stars. "
