Title: Petunia, the Demigod Witch
Rating: K
Summary: What if Petunia was a witch, and a demigod? She goes to Hogwarts before Lily and spends her first year learning more about her mother's realm and showing that not all Slytherin's are bigots and morons. This will come in handy when James and his dumb friends arrive and think that they can bully her because she's in Slytherin. A crossover of Harry Potter and Percy Jackson!

Chapter 4:Petunia Gets Revenge
Perseus showed up on Sunday, with Lily's reply. She took Snape's advice about the Malfoy family to heart. During that day she heard even her fellow housemates calling her a Mudblood. However no one dared to demand that she leave as Slughorn seem to take a shine to her. So, as long as she impressed him, she was fine. She loved her house to pieces but she couldn't stand the bullying that they seem to do to the other students. This wasn't cunning or ambition.
This was plain being nasty. She noticed three Slytherin's attacking a first year Hufflepuff. The little girl was so scared of them and the three of them, all older, were laughing at her.
"You don't belong here, Mudblood," one of them said, "And we're going to show you."
"Hay, leave her alone," Petunia said.
"I smell another Mudblood," one of them said, "Lucius needs to work harder to put you in your place."
"Yeah, I can't believe that we have one of you," said the other. "How about we take care of both of you, just so that you will cry home to your filthy muggle parents about how bad we are."
Petunia grinned at them and said to the girl, "Get up and get behind me. I don't want you to get hurt anymore."
The girl was confused but, thankfully, did as she was told.
"Oh look, the Mudblood is defending her own," said the third and they laughed.
"Cover your ears," Petunia instructed and she saw her doing just that.
She sent a scream at them that shattered all the windows. The three boys bellowed in pain and she heard their eardrums explode. They passed out, covered in glass and blood.
"Now they won't hear anything at all," she said and then she turned and did a series of finger movements that healed the cuts that the boys had done.
"Thanks," she said, "But why are you helping me?"
"Because insulting your blood, telling you that you don't belong, doesn't belong in polite society. I might wear the robes but I don't believe what they believe."
"What the?"
It was McGonagall and she was with Dumbledore and, to her complete disgust, Willows.
"She did something and they passed out," the girl said to her.
"Miss Evens, did you do this?" she asked her.
"I only did it because they were bullying her and saying that she didn't belong because she's Muggleborn. I can't stand bullies and I can't stand people that believe the same thing that Hitler believed."
McGonagall stared at her and then Willows said, "Like we believe the word of a filthy snake."
"That's enough, John," Dumbledore said. "So she helped you out."
"Yeah, she's cool," she said. "And she healed me."
She showed her arm and Petunia smiled at her.
"Then I think that fifty points to Slytherin for practicing inter-house relations is a proper reward," Dumbledore said and Petunia saw him giving her a small smile.
"Really, fifty," Willows said, sounding disgusted, "Fifty, to this filthy snake."
"Looks like I don't have to worry about the bigots in my own house. I see one in-front of me right now."
"Why you little-."
"Enough," Dumbledore said, "She's got a point. The points still stand."
"I'll take her back to her common room," McGonagall said and she led the Hufflepuff away.
Petunia glared at Willows, declaring open war. When he left, thankfully, Dumbledore turned to me and said, "You're not a normal Slytherin, which is good. Stick to your principles and you might prove everyone wrong."
"Thanks," Petunia said and she left the Headmaster behind.
That night Petunia found out that the three boys could no longer hear. She had to grin at the thought that they couldn't declare themselves better than other people. Of course, even though they couldn't hear, they could tell and seven older Slytherin's burst into the common room where Petunia was reading a book, wands out.
"Hay, Mudblood," Lucius snarled and Petunia looked at him, "They told us what you did to them."
"They were bullying a muggleborn."
"Mudbloods don't belong here," he said, "And when I'm done showing what we do to snakes that turn on their own kind."
Petunia grinned at him and said, "And you think that by attacking me that they'll get back their hearing. Well, sorry to burst your bubble."
"Crucio," Lucius said and Petunia felt the curse hit her shields that she always had up.
"The curse didn't work."
"My turn," Petunia said and she cast a spell that was in her mother's book.
All seven turned into cows. That action, alone, scared the daylights out of everyone.

"Well it looks as though she has proven that she can hold her own," Dumbledore told Lucius when they were finally turned back.
"I want her out of Hogwarts."
"And I don't believe that you have that power," he said, "In-fact the seven of you attacked her first and she defended herself. I would advise, in future meetings, to leave her alone. I'm sure that you would hate to be killed and served as dinner. What a shame that would be."
"My father is going to hear about this."
"Oh I'm sure that he will," Dumbledore said to him, giving him a look that told the Malfoy heir that he would be keeping a close watch on him and his friends.

The only plus side to doing what she did was that everyone in Slytherin was scared of her. Well except Narcissa, who believed that she was only protecting herself? Of course she tried to tell Petunia that she had to stop defending muggleborns.
"Here, in England, I am one of them," she said, "How can I not defend those that are like me."
"I know but Lucius thinks that you're rocking the boat," she said.
"I'll do more than that," Petunia vowed.
Petunia sent another letter to Lily, telling her about what had happened. She knew that she was darkening her sister to Slytherin but she always vowed to tell the truth. She also mentioned that she vowed that she would continue to defend muggleborn witches and wizards from the likes of Lucius Malfoy and his dumb friends. Personally she couldn't wait until Christmas when she would see her sister again.
The third week that she had been at Hogwarts the Slytherin's discovered that they were finally taking Flying lessons. Thankfully they were with the Ravenclaw's. Gryffindor and Slytherin never got along due to Salazar and Godric's feud. Personally Petunia thought the whole thing was just dumb. The person teaching them was Madam Hooch. She had them all stand next to a broom and follow her instructions.
Of course, it seemed that the hat must have made a mistake because Thomas Bloodheart, a boy in her year, couldn't do that. He got on before she had even said anything and took off.
"I don't need this class," he said and then he slammed into a wall.
Petunia mentally groaned, which caused the ravens to snicker.
"Maybe his brain will get some air," Narcissa said when Petunia told her what had happened. "So how did it go with you?"
"I'm natural at flying," Petunia announced.
"Once again, something that your naturally good at," she said.
