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

Harry Potter had a long life by the time World War Two was finally declared. Harry having fought a war against Voldemort and his cronies a few decades before was bad enough in his opinion. The fact was that the ministry was now completely destroyed. Voldemort had pretty much killed most of the people in that government by the time Harry killed him.

The fight was later passed on as a mere legend. Good thing they changed the names, one thing Harry hated was being famous. It often caused people to either treat him like a hero, or a good mark to try and swindle him out of a small fortune.

The battle had consequences that he would not discover till he was neck deep fighting the Nazi soldiers in France. The battle with Voldemort changed him in ways he did not expect. His magic prowess were enhanced to the point of invulnerability. His body would heal any injury and no disease no matter how foul would ever make him more sick that feeling than a morning hangover.

It was during the fighting in the war that he met and made his most trustworthy friend. Ron and Hermione had died a few decades earlier and he found making friends hard after their loss, but the American Steve Rogers was one he could get along. The two fought on even ground as they defeated the horrific monstrosities that the insane Red Skull made.

The last time he met with the then famous Captain America was when he went on the last mission for the allies, to stop a ship full of atomic bombs from reaching America. He felt sorry for his friend as he was never heard from again, having crash landed the giant plane in the area around the north pole.

Harry began to get rather bored, until a man calling himself the Taskmaster came to his underground bunker. The man actually tried to steal from him an old family relic, his old Firebolt of all things. He was stopped by him, and the Taskmaster must have been quite impressed because he offered to train him in things he clearly had no knowledge in.

Harry was bored so in an attempt to end the boredom he accepted. Training in the circus proved to be a wonderful experience. He learned thousands of ways to kill people he never even knew were possible. During this time he became friends with an arrow loving teen, who would later adopt the name of Hawkeye, since he never missed a single shot.

In the public the circus was just that, a circus that travelled across Europe entertaining people as they went from town to town. In reality it was a covert training place for the most skilled covert agents, assassins and thieves the world had ever known. Or at least it was.

The circus was disbanded and most of the people either recruited or killed by the intelligence agencies of both America and Great Britain. Harry had consider himself English since his birth so he was rather forcefully recruited into MI:13. He was initially an infiltration specialist, and was good for friends with good old 007. He often joked that his friend had slept with women on every country on the globe. James could not argue against it, because more than likely he did.

In a short time they decided that he would do better in the assassination of dangerous terrorist and criminals, the body count he had earned him the name of Reaper. His colleagues in section M made a joke of it and got him full combat armor all black and dark grey, had a hood and a half skull shaped mask. When Harry put it on for the first time. He made quite the sight to see.

In the criminal underworld the most successful crime lords knew two things they never wanted to do. First was to mess with Nick Fury, the other was mess with the Reaper and you would end up on the buffet menu for worms. Harry loved his job, he got to kill the most insane, paranoid, and psychotic people in the world. You could say many things about having to do this for a living, but at least it was not boring.

Harry had taken a liking to sniping targets as of late. Having magic infused bullets he could do things most other snipers could only dream of. His current target was the criminal known as the Black Widow, he had to admit. She had a figure most pornstars would kill for, and her face and hair made her look down right seductive.

The thing was she knew this and used it in a very efficient way. She stole things of great value, did assassinations, even was a weapons dealer. Everything and anything to make as much money as she could and as quickly as she could. She became a target the second she killed enough innocent bystanders that got his section chief's attention.

The section chief did not care about how many scumbags she killed, but when she killed the friend of the daughter of the prime minister of her country. She was put on a kill list faster than the man could down a glass of whiskey. Reaper took the assignment thinking maybe he could try some of his new disintegration shells.

When she left the others began playing the song Don't fear the reaper. Harry glared at them. "Haha, very funny. See if I come to your rescue when you need me, lousy disrespectful brats." They stopped the song not wanting to piss him off anymore than he already was.

Harry began to follow the Widow from a long distance. He was currently taking aim when he heard someone clearing his throat. "Hawkeye, I am a little busy." Clint looks almost hurt by the way he was greeted. "Well good day to you too, Reaper. We haven't seen each other in a few years and that is the greeting you give me?"

Harry did not bother moving, he did not want to let his target out of his sight. "Hawkeye, quit wasting time. I know you work for the one eye bastard and you are here for something. So tell me or leave. I got a red head to kill."

Clint leaned against the wall. "Actually I wanted to ask you something about that very same red head. I have a request from an old friend?" Harry got up and looked at him with an almost cruel glare in his eyes.

"You are not asking me to let her live? She killed one too many an innocent bystander, she is a menace and you know how I deal with people like that. " Clint had to admit she was dangerous, but Nick Fury had told him he wanted to recruit her for his agency. Clint had to try and talk his old friend into letting her live.

" Look she is also skilled, smart and an absolute beauty. Killing her would be like destroying a work of art. " Harry glared even more at him." I have done that, don't tell me you actually believe the giant zeppelin explosion was an accident? " Clint told him that many innocent bystanders died on that too. Harry simply replied a good nazi was a dead one.

" Look let me try and reform her. If it works you will not have to live with killing such a beautiful lady. " Harry was tempted to tell him to go and let him do his job. But he did owe him a favor or two, so he put away his rifle. The rifle simply banish from sight. " Fine. Go ahead and try and recruit her. But if she escapes and goes on another murder spree, we will finish our old argument about which hurts more your arrow or my bullet."

Clint looked pretty happy to hear that. "Thanks, Reaper. It sure is nice having friends like you." Harry took out what looked like a playing card and threw it at Hawkeye. "If you need my help use that, till then happy hunting Hawk."

His section chief nearly fell out of his chair. He simply was laughing so hard. It was the first time since he knew the man that the Reaper actually failed to kill his target. Some of the other men in his section came to his support saying that he was only human. Harry believed they did it to apologize for their little joke with the song.

Natasha Romanova was not a happy woman when she met Clint, not happy at all. She went to all that trouble to gain the attention of the much feared Reaper, and she got him to try and recruit her instead. She even wore her best uniform and it was one that really showed her figure too.

"I don't think you understand. The Reaper does not recruit people, he kills them. Had I not interfered you would be one more in his kill count. " Natasha smiled her most seductive smile, " Me, killed with a mere bullet shot from a sniper rifle? I was more than prepared for him. What I want is him in my bed and working with me. "

" I know him for over a decade, you know how many women I known him to sleep with? " Natasha said about 50. Hawkeye made an 0 with his hand." Nope, nada , zilch, nothing. Not a single one. The guy makes most priests look like James Bond in that regard, and that is saying something. "

Natasha agreed to be part of S.H.I.E.L.D if for no other reason than someday seeing if she could one day romance the Reaper. Nick Fury did not like the way the same Reaper called him as he heard the report from Hawkeye. " I know I am not the most friendly person in the world, I know that I can rub some people the wrong way. But what did I ever do to him to deserve that kind of hate?"

Hawkeye did not have a clue. Harry actually never told him his reason for hating him. "Maybe it has something to do with the fact that you are keeping the person he once loved as a brother as a popsicle for so many years." Natasha simply could not avoid saying that. It simply was too good of a chance to miss.

"The only one I have in cryogenic suspension for a long period of time is the believed dead Captain America, he froze when he crashed landed that bomber at the end of the last World War. Are you telling me he knew the Reaper well enough for them to care about each other as brothers."

Natasha took out a picture of a young man and the very same Captain America side by side from hip pocket. "They fought against the best the Red Skull could muster, liberated concentration camps and even was present as his best man during Roger's wedding. He was a legend in where I was trained, and the Baron considered him an ideal candidate to join his organization."

"So the Reaper was a member of H.Y.D.R.A." Natasha smiled again, "No he was not, they stopped trying to recruit him when he killed every single recruiter they send to find him. The way he left their bodies made Vlad the impaler look compassionate."

" So you don't think he could work for us, even if Hawkeye and you tried to recruit him? "

" I know the man since my circus days. I am pretty sure that he will not leave his current place of employment for anything less than a direct order from his section chief. I also know said section chief would give him his own daughter as a maid, to keep him. "

Nick Fury had just one question. Where does the Reaper work? Natasha was quite happy to answer that. "As the chief eliminator in Sector M of MI:13. I would even date him if he came working for me. Instead if he had not interfered I have would have killed by him."

"You are very welcome Ms. Romanova. I am glad that I could keep such a beauty such as yourself alive. " Nick almost wanted to scream at the idiot for shamelessly flirting with a fellow agent. Instead Natasha smiled and walked over to where he was, and gave him a swift and painful uppercut to the jaw.

She looked down at him on the ground and smiled, " Let's keep things professional or learn to like eating a liquid diet. Is that clear?" Clint was in a lot of pain and slowly got up and said it was crystal clear.

"It is good that you two set some ground rules. Because as of right now you two are going to be working together. " Clint finally understood why his friend Harry hated the one eyed man as much as he did.
