A/N: Hello, people of Fanfiction! I'm Caleo4evah. This is my first fanfic and stuff, so I'm sorry if it's not very good. Also, I haven't read Harry Potter in a very long time, so it won't be as detailed as it should be. Sorry, I'm lazy. And I have homework. So yeah.

Disclaimer: I wish I owned PJO, HOO, HP, or any other acronyms you can think of, but I don't.
And without further a doo (or whatever the saying is), here's the story!

Percy wished he could have a break.
The second giant war had ended, the two camps were finally getting along, and he wanted to spend some time with his friends and girlfriend. But nooooooo. The fates just had to switch his mind with some toddler.
The last thing he remembered was celebrating his 17th birthday at his mom's house. There was blue cake. And blue cookies. And then he wasn't there anymore. He was riding on a flying motorcycle, with some giant, hairy stranger, in the shape of a two year old. Or one year old. Him, not the stranger. It didn't matter. Who in their right mind would take him away from blue food?! IT WAS BLUE FOOD! Percy would march to mount Olympus and demand justice...if he could. But he couldn't exactly walk at the moment, unless he wanted to plunge to his death. Dying was something he tried to avoid on a daily basis. Plus, with his luck, he'd probably end up tripping and falling on his face. Which wasn't his fault, considering his tiny legs.
"It's gonna be alright, 'Arry," Percy was pulled out of his thoughts. The giant stranger had just said something! But why did he say 'Arry? Was that the little kid's name? Kind of a weird one, unless the guy meant Harry. That made more sense. Harry. That was him, now, unless this was a dream. He really hoped it was.
Minutes later, Percy felt the motorcycle coming to a stop. He was lifted up, and was put down somewhere. The big guy knocked on a door, then left, leaving him alone. Probably at some person's house. Faking unconsciousness, he heard the door open, and a gasp. The person picked him up, and brought him into the house. Another person said something, but to be honest, he wasn't really listening. He was thinking. What was happening at home?

-THE FIRST EPIC LINE BREAK OF THIS FANFIC IS HERE-

Annabeth didn't cry.
She knew it. Her friends knew it. Pretty much everyone knew it. But she decided to break that rule, at that moment. They were celebrating Percy's birthday, when he disappeared. Just like that. No poof. No flash of light. No explosion.(A/N: If you get that reference, please leave a review!) He was...gone. About 15 seconds later, she and the others were IMing Olympus, trying to find out what happened. But the Olympians swore that they had nothing to do with it. Even Hera.
Next, they contacted Camp Jupiter. But the demigods there said they hadn't seen him. By that time, Annabeth was starting to panic. Camp Half-Blood didn't see anything, either. Or Thalia. They IMed everyone they knew. Nothing.
That was when Annabeth started to cry. This was his second kidnapping in less than two years. Would her Seaweed Brain ever have any peace?

-THIS SECOND LINE BREAK IS EVEN AWESOMER THAN THE FIRST-

Six Years Later...

Percy hated the Dursleys.
They treated him like dirt. The kind of dirt that you scraped off your shoe. The kind of dirt that even more dirt would hate. They made him live in a cupboard, for Zeus's sake!
Why was he here?
This Harry kid didn't seem that special, although thanks to Percy, he was now a (sort of) kid genius. But only because there was a high-school education living in his brain-and although a dumb one, still high-school level.
But school was still really boring.
And the way his 'Parents' showered his 'Brother' with toys and candy and whatever- it was disgusting. If they knew how horrible he acted in real life...
Nah, they'd still spoil him.
At least something good had come out of this. Percy was now a great cook! Before, he couldn't make a piece of toast to save his life. But now? He could make everything, including...
...Blue Pancakes.
Yum.
But even though he could now bake stuff without burning down the kitchen, he wished more than ever for his old life. For his family. For Annabeth. But he'd have to endure this awful life a bit more.

-THIS IS THE THIRD, EPICER, LINE BREAK-

Almost everyone had given up.
It had been six years. Most of the campers had given up looking for Percy after two years. The hunters, three years. The gods, four. Even Percy's closest friends admitted he wasn't coming back after five years of nothing.
But not Annabeth. She swore never to give up, no matter what it took. She would find Percy, if it was the last thing she'd do.

-FIRST IS THE WORST, FOURTH LINE BREAK IS THE BEST-

Almost Four Years Later... (1st person POV because I feel like it)

Something was going to happen. I could feel it.
It started when I found a letter. Addressed to me. Or, at least, Harry Potter. It even specified the cupboard I lived in. Of course, my 'Uncle Vernon' found out, and wouldn't let me read it. Then another letter came. And another. And another. No matter what my adopted 'parents' did, the letter always seemed to find me. Right now, we were on a boat. A boat. I tried not to laugh. Maybe if I rocked it back and forth a lot, Dudley would do something hilarious. Well, didn't hurt to try. The boat started rocking, slowly at first, but getting stronger and faster. It wasn't long before my 'family' all excused themselves to go throw up.
That was when I heard the crash. And the screaming. There was a loud thump above me, and then it was quiet. Huh.
I stood up, but before I could go anywhere, a person came down. The guy was...large. And hairy. He looked familiar. Then, with a start, I realized it was the same stranger who had brought me to the Dursleys.
That gave me a sort of hatred to the man.
"Who are you?" I asked. May as well begin with a question. "If you hurt the others...thanks. That would be awesome."
The big hairy guy laughed. "Nah, I didn't. But I gave the fat boy a tail!"
"Nice!" I nodded with approval. "Considering he's a pig."
Okay, maybe I hated him a bit less.
"And yer Harry Potter,' He said. I was tempted to say "No, I'm Percy Jackson, an American demigod whose mind was switched with Harry's when he was a baby. ' But I decided against it. The last thing I wanted was to be considered crazy when something big was about to happen.
So I just nodded.
The stranger grinned. "I'm Hagrid, an' this is for yeh.' He handed me a letter. The letter. Except now, it showed the boat I was in. Ripping it open, I pulled out a piece of paper. I was about to read it, but then I remembered an important detail.
"Um, Hagrid?" I held up the letter. "Could you read this? I have dyslexia."
He looked surprised. Maybe the stuff he used to find out everything about me didn't include the reading disorder.
"Sure." He answered, a confused look on his face. "It says (insert whatever letter said here)"
My eyes widened. "Are you saying that I...I'm..."
"Yep." Hagrid nodded. "Yer a wizard, Harry!"
