Author's Note: Hello, everyone! Welcome to my new story!

This is a Percy Jackson and Winx Club crossover. For those of you not familiar with Winx Club, it's an Italian animated series about fairies attending college and stuff. It's fairly similar to Harry Potter in some ways. I got into the series with my sister when we were younger. Since we watched the 4Kids TV version of the series, we thought it ended. I then found out that there were a few more seasons and movies and decided to watch them.

Anyways, I got this idea for a oneshot, but I wrote some more for a longer story. This takes place after the Blood of Olympus and before the Trails of Apollo for Percy Jackson. For Winx Club, this takes place sometime after Season 3, but before the Secret of the Lost Kingdom.

If you enjoy this story, please follow or favorite it, or leave a review if you want to see more!

Chapter 1: A Really Strange Encounter

~%%%%~

The sky was a colorful red as the sun began to set in the distance. Not much animals nor people were out as the day was coming to an end. The only sounds were the growls and roars of monsters.

Yes, you read that correctly.

The woods near Camp Half-Blood, a safe haven for Greek demigods, were full of monsters. Not many were close to the camp, but any camper could hear them from the middle of the camp.

Near the beach, away from the main camp, was a young teenage couple. A guy with tan skin, jet black hair and sea green eyes sat looking at the waves with his girlfriend. She was a beautiful girl with long blond hair reaching her shoulders and gray eyes. Both of them were jeans and orange T-shirts with 'Camp Half-Blood' written on the front. The two of them were doing nothing but sitting on the beach, enjoying each other's company.

"Seaweed Brain?" the girl, Annabeth, asked, "we should probably head back to camp. We got to get up early to head back to New York."

It had been at least a year since Percy, Annabeth's boyfriend, had been in New York. Since Hera the "so called goddess of marriage and family" had sent Percy off to the other side of the country, where he met Roman demigods, and then he, Annabeth and many others had to fight in the Giant War. Percy hadn't seen his family for an entire year. It was mid-November, they had to stay at the camp for mouths to make sure everything was getting back to "normal."

"Alright," Percy said tiredly. He got up from the sand and put his arm around Annabeth as she got up. The two began walking back to camp. Unfortunately, they didn't make it far.

A strange light came from the woods near the Poseidon Cabin. The light had been a bright yellow, like the sun. Usually when a strange light appears anywhere near the camp, it meant either a god or goddess was on their way or a monster was coming. It was usually the second option.

"Are you serious?" Annabeth muttered. She brought her hand to her hip to make sure her dagger was there. It was. "Let's go. If it's a monster, it'll probably cause the camp more trouble."

With Percy following behind, sword in hand. The two walked deep into the woods, past Zeus's Fist and near a creak where Percy had claimed years ago. Annabeth grabbed Percy's arm and pulled him behind a rock.

In the clearing near the creak was a group of girls. Each girl had long flowing hair, like Disney princesses, but each of their hair were different colors. One girl had blond hair while two others had brown, that was normal. What wasn't normal were the other girls' hair. An Asian looking girl had long dark blue hair in pigtails, another girl had short magenta hair and the last girl had long fiery red hair. Annabeth could sort of tell that she was the leader of this group, just by looking at her.

"Stella!" a girl with black skin shouted at the blond girl. "What did you do? This doesn't look like Gardenia!"

"I don't know!" the blond girl said shrilly. She got up from the ground and marched up to the other girl. "Since my ring is missing, my powers aren't acting the same."

The girl with fiery red hair put a hand on Stella's shoulder. "Don't worry, Stella. We'll figure that out later. Right now, we need to figure out where we are."

"I'll check my Data Base," said the magenta haired girl. She had pulled out a small phone-like device and was typing on it fiercely. "We're in New York, somewhere on Long Island."

"New York?" a girl with tan skin said. "Where's that again, Bloom? My knowledge about this planet's not that good."

"It's in America, Flora," said Bloom kindly. "Unfortunately, Gardenia is on the other side of the country, in California."

"What's going on?" Percy whispered to Annabeth. "Who are these girls?"

"I don't know," said Annabeth in thought. The gears in her head were moving and turning, trying to figure out these girls. "They're definitely not normal mortals."

"Yeah," Percy agreed. "Did you hear that girl? 'What's New York?' Was she serious?!"

They both turned back to the group. The Asian girl was arguing with Stella for some reason.

"— can't just sit around! We need to find the Trix!" she said.

"Musa's right," Flora said. "The Trix stole the ring before, it might be possible that they stole it again."

"I already told you, Flora, it wasn't the Trix!" Stella shouted. "It was some girl with flaming hair! Her hair was literally on fire!"

Annabeth's eyes narrowed at those words. The creature she was describing was an empousa: a monster that took the form of human girl, but had flaming hair and a donkey leg. If an empousa had targeted these girls, that could only mean...

"They're demigods," whispered Percy.

Annabeth nodded. "I think we should help them." She stood up and looked towards the girls. "Excuse me?" Annabeth called.

The girls all turned to look in Annabeth's direction. They looked extremely surprised and nervous.

"Who are you?" Musa asked, clenching her fists.

Annabeth held a hand up in a calm matter. "My name's Annabeth, and this," she gestured to Percy, who had gotten up too, "is Percy. We... uh, saw you teleport here and thought that we should investigate. Don't you need help and were you followed?" she asked lastly in a serious manner.

"We don't think so," Bloom said stepping forward. "We teleported from veryfar away from here, so it would be impossible —"

Before she could finish, a low growl came from behind her. Something large and fast leapt at Bloom, pushing her to the ground. A hellhound had stuck up behind her. It was as large as a small car with thick black fur and blood red eyes.

"Bloom!" her friends all shouted.

"Dragon Fury!" Bloom yelled.

A red jolt of light came from her hands and the hellhound was thrown across the creak. It landed against a tree and whimpered in pain.

Annabeth's eyes kept going from Bloom then to the hellhound. Bloom had conquered fire. Was she a child of Hephaestus? It was not impossible for Hephaestus's children to control fire, but it was rare. The only one who could control fire was Leo. But he was still missing since the Giant War and according to all of Hephaestus's current children, there hadn't been a fire user in a hundred years.

Her thoughts were interrupted by more growls. More hellhounds emerged from trees and bushes. Annabeth counted at least twenty surrounding them.

"Oh my gosh!" Stella yelled frightfully. "Giant dogs?! What?!"

"Calm down, Stella," the magenta haired girl said. She glanced at Bloom and whispered, "Should we transform?"

Bloom shook her head. "No, we don't know who these people are. They might not know about magic." In her opinion though, Bloom thought that the two did know about magic. Annabeth and Percy looked too calm for non-magical people. They were looking at the giant dogs with guarded expressions.

"Just use your magic," Bloom whispered back. "Dragon Fury!" she shouted again at a giant dog.

The rest of the girls followed her example.

"Green Luxuriant Ivy!" shouted Flora. Large green roots came out of the ground and rapped themselves around three monster dogs. The dogs were carried down into the earth.

The black skinned girl and Musa join hands. "Rubber Chord Bounce!" they shouted together. Something pink camefrom the other girl's hands and there was a low boom, almost like a drum and it was thrown towards another two hellhounds.

Annabeth and Percy watched transfixed at the girls.

"Come on!" Percy shouted rising Riptide, which was now it sword form. "Let's help them!"

Annabeth nodded fiercely and drew her dagger. She and Percy went for the nearest hellhound that was about to attack Stella.

"Light Waves!" Stella shouted. When nothing happened, she looked at her hands in confusion. "My powers? What's wrong with them?"

She gave a loud yelp as Percy stepped in front of her. "Don't worry, we'll handle this!"

"Excuse me! But I can take care of myself, thank you!" Stella said shrilly.

In an attempt to prove herself, Stella grabbed Percy's sword and threw it at one of the hounds. The sword went right through the dog's face and it exploded into golden dust.

Percy gaped like a fish. "Woah."

Stella turned to grin at him. "Believe me now, Water Boy."

At this, Percy frowned. "How do — I mean, what do you mean?"

Stella pointed at the ground. "Your pants aren't getting wet. That's usually a trait that people who could control water have." She glanced at her black skinned friend. "To bad Aisha can't do that. It would sure come in handy."

"She can control water?" asked Percy curiously.

"Less talk, pumpkin and more fighting!" Stella said as she kicked a hellhound.

The battle continued until every hellhound was a pile of dust. When they were finished, everyone nearly collapsed.

"That was ruff," huffed Aisha. She bent down and put her hands on her knees.

"What in the world were those things?" Musa asked to the group. "Overgrown dogs?"

"They were hellhounds," Annabeth said, putting away her dagger.

Bloom's eyes lite up. "I've heard of them! They come from the Underworld in Greek Mythology. They guard Hades's palace, I think."

The magenta haired girl looked at her friend. "Greek Mythology? What's that?"

Bloom was about to explain, but Percy cut her off. "How do you not know what Greek Mythology is? Did you not pay attention in school or something?"

Musa and Aisha laughed loudly at the dumbfounded look on their friend's face. The girl then looked angry.

"Tecna not paying attention in class? Oh my!" Musa laughed.

Tecna glared at her Musa then back at Percy. "Laser Cage!" she shouted rising her hands.

A green net appeared around Percy before he could move. He slashed his sword at the ropes, but they were made of electric lines.

"Percy!" Annabeth shouted. She drew her dagger again and pointed it at Tecna. "Release my boyfriend! Now!"

Tecna seemed to regain herself, so she wave her hand and the cage disappeared.

"How did you do that?" Percy asked her.

"No! Wait just a second!" said Bloom angrily. "Where did you get that sword?" She pointed at Riptide in Percy's hand. "It looks like it belongs in a museum! And who are you guys?"

"The question is not who we are," Annabeth said gesturing to herself and Percy, "but who are you?"

The girls all exchanged looks.

"My name is Bloom," Bloom said helpfully, "and these are my friends Flora, Musa, Stella, Tecna and Aisha. We're... uh, college students."

"College students?" Percy asked. "Are you guys from California? Do you guys go to New Rome University?"

Bloom blinked at him. "New Rome University? New Rome? There's no such thing."

Annabeth and Percy exchanged looks.

"Alright, look," Annabeth began, "I'm sure we're all confused, so I think I just cut to the chase. Shut up, Percy!" She added as Percy snorted. "Are you girls demigods?"

There was silence as the girls proceeded what Annabeth asked.

"Demiwhats?" asked Musa with a raised eyebrow.

"Demigods," said Bloom, "they're like the children of the gods."

"But what gods?" Aisha asked.

"Greek Gods," said Annabeth. "I'm not sure if this will come as a surprise to you, but the Greek Myths are real and are living here in America. Me and Percy are demigods. But the main question is: are you?"

"Uh, no," said Bloom awkwardly, "definitely not. None of our parents are gods."

"Then how do you —" Percy started, but a howl from far away seemed to catch everyone's attention.

"More hellhounds?" asked Stella frightfully.

Annabeth nodded. "We should probably get them to camp. Chiron might be able to provide some answers."
