In fourth year Harry defeats Voldemort but finds out he is to be raised by one Severus Snape, who is his father, neither like this at all. Warning, everyone is behaving badly here. Harry is not a nice guy either.

Not My Family:

Cokeworth 1995:

Harry looked at his hated potions professor, he was not going to let this man win. He had lost every right to the Potter properties, his own godfather disowned him and now this. He hated the man before him, hated the very sight of him and was not willing to ever be his son. He really did not care if Snape tore him apart piece by piece he would never, ever accept this man as his father. This was his reward for defeating the evil dark lord Voldemort? Thrust into a new hell with another person who hated him?

"Wipe that defiant look of your face at once!" Snape snarled.

"I don't care what you do to me." Harry said, and if Snape had been reasonable he would have known Harry had been pushed beyond the brink. "I don't care if you beat me, whip me, tear me apart piece by piece, I swear on my life and magic I will never, ever accept you as my father or family."

"You will, there is no choice the law is clear." Snape said coldly, "you have no choice!"

"I do, I always have a choice, and my choice is pain and death instead of accepting a rapist piece of filth like you as a father."

"Go to your room, when you come down again you will accept your lot as my son or you will suffer." Snape said.

"Go to hell." Harry snapped.

Later Snape would regret what he did next. He would regret not letting Harry go and regret his temper getting in the way of common sense. Yet he had not and sent off his son bleeding and hurt but not broken to his room. When lunch came and the insolent boy had not come down he went to look for him. He found the cooling body of his son on his bed, several vials around his body. He paled and called for the headmaster and then his ex godfather who was not amused at all. Sirius Black looked at the dead boy and was more angry than anything.

"The little fool, you were not harsh with him, you gave him a home, and were reasonable!" Sirius said, "you only thrashed him for disrespect, I got thrashed if I was nice to a house elf."

"We will have to come up with a story for this." Dumbledore said sadly, "that Voldemort had caused more damage than we knew and that is not far from the truth."

"I should not have been so harsh, the signs were there." Snape said, "first I said I did not want him then this, I was not aware he would resort to such a thing."

The funeral took place a week later. No-one but three people would know that Harry Snape had killed himself. Better to let them think he had died from what Voldemort had done to him. He was cremated and his remains sealed in the Prince vault and Snape went back to Hogwarts. It was not as if he loved the boy, but he had been his heir, now he would have to find a witch to marry and to have his heir for him. Sirius felt guilty about what he had done but he had a house to revive and so he went on to marry himself.

Colorado Springs June 2018:

Henry Bas Perks smiled at his dear wife of twenty years. Sally Ann Perks had saved him and helped him when no-one else would. Now twenty years later they had three beautiful children, triplets a rare thing in the magical world. There was Sarah Ann, then Hanna Ava and finally Robert Evans Perks. They were graduating from high school today and had already completed their NEWTs. The man who once had been known as Harry Potter had managed to fake his death and now was here, safe and well. It was Xeno who had blood adopted him, Henry had white-blond hair now but his eyes stayed green and his children had the dark hair of their mother and their grandfathers blue eyes and build. No-one would claim that he had been Harry Potter or rather Harry Snape ever.

"I wonder what is going on back in England?" Henry asked.

"Not much, bigotry and all that." Sally Ann replied, "but we are Americans, and our children are too."

"Yes that is true, but what if, well I still worry." Henry said.

"Don't, you were a victim and you needed a way out, and you got it." Sally Ann said.

Henry smiled, Xeno had been the father he always wanted. A good man that had secretly taken him in even before he was found out to not be a Potter. He had given Harry then a chance a way out, and it had worked. Everyone believed Harry had died and three people believed he had killed himself. What was more is that Harry had secret talents and had never shown his true self at Hogwarts or even to his relations. No-one even now would connected Henry to Harry through mannerisms either. Still he worried a bit when his children were born, but now they were adults and as safe as one could be here. He worried that Hanna wanted to be a curse breaker but he did not need to worry about that, Henry had taken his sweet wife's last name to protect them.

Hogwarts February 2022:

Dumbledore was feeling very old now, too bad he had to lie to Severus, he knew Harry was still alive. He knew where he was and was going to meet him as the last thing he ever did. He never saw the figure enter his chambers until it was too late. His wand was summoned and he looked up to see Harry Potter standing over him. He wondered how he had got here, was he not in America? His heart pounding he tried to call for help but was not able to.

"You know how all those death eaters who got away have died?" Harry said, "it was easy for me to fake my death and you never did know me."

"What do you want?" Dumbledore said.

"The last thing you will ever see is the death of your pet death eater." Harry said coldly, "this face is not my real face, that you will never see, my wife, well she has no idea how tainted I am, how evil. I blame you for that."

"What will you do?" Dumbledore said fear coursing through him.

"What I do best, kill." Harry replied, "but I am merciful and it will be quick."

Dumbledore watched as a bound and silenced Snape was brought into the room and there he died. Harry did not allow him to speak and the last thing Dumbledore thought was how he wished he had done better to help Harry. Harry handed the wands back over and with help from Dobby the scene was that of death eater Snape casting the killing curse at Dumbledore and Dumbledore casting a cutting curse as the last act of his life. Harry left, and once far away he shifted back to his Henry Perk look and headed out of England and back home. After all he traveled for work so his family was not expecting him home until tomorrow.

Yes that was a bit mean and yes I did make Harry here a little like Dexter in the end.
