A/N : Hello earthlings! So this is a crossover between Teen Titans and Percy J. & The Olympians(obviously). XD I know it sounds kinda weird but it's gonna be great, I promise! So get reading!

Chapter 1 : Another Sunday

Beast boy leaned back on the couch, letting out a deep sigh. It was just any other Sunday in the Titan tower, which basically meant there was nothing to do. Cyborg was in the kitchen, making what sounded like the biggest lunch in the history of mankind while Raven was reading at the table. Robin and Starfire were no where to be found, but Beast Boy would have bet his entire CD collection that they were together. Meanwhile the green titan let out another sigh, letting his complete boredom seep into the sound.

"Dude, this is unbelievable! There is nothing on!" The shape shifter complained flipping through the TV channels.

Cyborg looked up from his meal, his mouth stuffed with food. "We have over a thousand channels, B. Something has to be on."

Beast Boy mumbled something about a stupid, out-of-date half-robot before continuing his search.

The afternoon dragged on and just as Beast Boy thought he would die from boredom, he heard the wonderful sound of the Titan alarm signaling trouble.

"Yes!" Beast Boy jumped off the couch in excitement. "Trouble!"

Raven lifted an eyebrow at her green comrade while Cyborg contacted Robin. "And an attack on the city makes you happy because…?"

"Anything is better than sitting here watching you read," Beast Boy retorted, giving Raven his biggest grin. The other titan simply rolled her eyes before turning away.

Cyborg looked towards his friends, concern flooding his features. "Robin wants us to meet him downtown."

"Wait, how does Robin know where the trouble is?" Beast Boy asked, a bad feeling forming in the pit of his stomach.

The mechanical titan glanced at his friends with a worried expression before facing the door. "Because Robin and Star are the ones being attacked."

Downtown Jump City resembled something close to a war zone when the three teens finally arrived. Abandoned cars sat dented and smoking at the sides of the roads, their passengers having fled them to escape the chaos. The sidewalks were covered in glass from broken store windows and screams echoed through the streets like a horrible nightmare.

Cyborg looked down at the destruction from the claws of his green, pterodactyl friend while Raven floated along beside them on a disc of black energy. The friends flew along, each caught in steely silence of worry. The tension grew as the sounds of battle grew closer and closer. Shouts, crashes, and strangest of all, a deep barking sound unfamiliar to all, even the animal shape shifter of the group. Not knowing what to expect, they each held their breath as they rounded the final bend in the road.

"Look out!" Robin screeched, just as a shape formed from the shadows. The three titans froze, while their brains tried to process what stood before them.

In front of the teens stood a dog so big it made Beast Boy's wolf look like a newborn puppy. It's long black hair was knotted and tangled and dried blood stained it in patches. Its long claws were covered in pieces of ripped fabric as they tightened, leaving cracks in the warm absalt. But none of the titans were looking at that. Their gaze was captured by the dogs sharp canines and the froth that was spilling out of its mouth. And above its gaping maw, they were staring at its beady red eyes, intent on its prey and its kill.

Meanwhile Robin and Star were fighting for their lives, for they were locked in battle with four more of the devilish dogs. Starfire let out a loud battle cry before sending a wave of star bolts down on the pack. A few yelped in pain but otherwise seem unaffected by the attack and one swiped a massive paw at the flying alien, sending her crashing into a building. Robin wished to help but he was having problems of his own. One of the dogs had grabbed hold of the Boy Wonder's arm and it's razor sharp teeth were tearing into his flesh, refusing to release him. He screamed in agony but managed to send a few sharp kicks at the beast's ribs, forcing it to back off.

At the arrival of the three teens, two more of the dogs broke off from the fight to confront the new threats. Seeing his chance, Robin jumped on the nearest dog to shout orders to his comrades.

"One for each of us team! Titans go!"

The team immediately jumped into action. Beast Boy quickly took the form of a T-Rex, the only creature he could think of that was larger than the beasts. Letting loose a vicious roar, the changeling charged, ramming into his target with his massive head. The dog released a screeching whine as it slammed into an already destroyed car. In the same instant Cyborg and Raven attacked their own dogs, Cyborg wielding his sonic cannon while Raven used her dark magic to pummel the side of her enemy. Both attacks should have gravely injured the dogs, but they merely flinched before continuing in their advance.

Starfire pulled herself from the rubble, more irritated than hurt. Her eyes were immediately drawn to Robin who was now attempting to battle two of the dogs in an attempt to keep them away from his alien friend. As he hit one of the beast hard in its snout, the other snuck up behind him, unseen by the Boy Wonder. With one swift motion, the dog picked up Robin in his massive maw, apparently swallowing him whole.

"Robin!" Starfire screeched, her heart broken voice echoing through the street causing the closest titans and dogs alike to freeze in their tracks.

In gorilla form, with his muscular arm wrapped tightly around his dog's neck, Beast Boy looked over, his eyes growing wide in shock.

Starfire's pain quickly faded to anger as she glared at the evil canine. But as she prepared to attack, a strange look appeared on the dog's face. Its eyes widened while its cheeks expanded, looking very much like Beast Boy after eating too much tofu. A horrible gagging sound began, followed by a very slimy, stunned, yet unharmed Robin emerging from the dogs mouth. Beast Boy's look of concern immediately changed to one of pure amusement as he switched back to human form.

"Maybe bird boy wasn't on the menu!" The shape shifter blurted before being overcome by a helpless fit of laughter.

Robin glared over at the changeling but even Starfire let out a small giggle before leaping back into the fight.

Cyborg and Raven, having missed the drama, were still locked in combat and getting no where. Hundreds of punches from Cyborg and dozens of cars in the face by Raven were useless against the dogs and the two titans were quickly tiring out.

"Titans fall back!" Robin shouted out, making a quick decision. Fighting wasn't working and most of the teens were either wounded or exhausted. They needed to regroup if they were going to have a chance of stopping the attack.

Beast Boy gave the dog he was battle one final shove, before preparing to retreat, when a flash of orange appeared at the edge of his vision. Instinctively, the green teen whipped around, ready to face another threat. He froze in his tracks while his emerald eyes widened, not believing what he saw.

At first glance it appeared to be just any other teen ruffling through his backpack. His hair was light brown and unbelievably curly while his eyes were a piercing blue. He wore a normal orange t-shirt that read "Camp Half-Blood" but otherwise had no importance to Beast Boy. But the shape shifter's eyes picked up other details. From the bag the teen was pulling out weapons. Arrows, spears, and shields alike, all lay around the boy's feet. And of course there was the thing that had caused such a reaction from Beast Boy to begin with.

From the waist down, the teen had cloven-hoofed, very hairy goat legs.

"That's it," Beast Boy retorted, rubbing his eyes in disbelief. "I've finally gone crazy."

At the sound of Beast Boy's voice, the half-goat looked up, his eyes clouded with fear. With a glance at his bag, he pulled out what he must have been looking for the whole time. A long, razor sharp sword that gleamed in the sunlight. Beast Boy crouched down, ready for the teen to attack.

"Beast Boy, look out!" The goat boy shouted, surprising the changeling by tossing him the sword. Beast Boy automatically caught the blade before spinning around, stumbling under the unfamiliar weight. With a large gulp the green titan watched as one of the devil dogs charged towards him, revealing its teeth in a snarl.

When the beast was almost on top of him, Beast Boy made his move. With superb agility, the changeling dove under the massive dog, stabbing up with the sword without thinking. As he felt it lodge in the hound's underside, Beast Boy rolled away readying himself for another attack. The green titan's preparation wasn't needed. As soon as the sword had made contact the dog had begun to howl in pain and moments later it exploded in a shower of sand.

Stunned, Beast Boy walked over and picked up the blade. Running his hand over it's smooth surface, he was surprised to find it free of blood. It appeared to be made of a strange metal, somewhere between steel and bronze. Looking over at the sidewalk, he noticed that the other weapons were made of the same material. A thought blossomed in Beast Boy's head and he immediately took action.

"Raven!" He shouted across the street, watching as his cloaked companion put up a dark shield of energy between herself and a dog. When he got her attention, Beast Boy motioned towards the arrows and back at the dogs, hoping the dark titan would understand. Raven raised an eyebrow at the changeling but she did as he asked.

"Azarath Metrion Zinthos!" The empath chanted, floating in the air with her legs crossed and focusing her powers on the arrows. Each weapon was wrapped in energy and lifted into the air, their sharp points pointing towards the four remaining hounds. All at once, the army of arrows flew towards the dogs, each one hitting its target. Upon impact, the demon-like beasts were killed, just like the first, collapsing in a pile of sand.

Raven landed next to Beast Boy just as the other titans came running up. The two stared at the dunes of sand, not sure what to think.

"Beast Boy, Raven! What happened to the dogs?" Robin demanded as he glanced down the street.

Beast Boy merely pointed at the sand, unsure if he could find his voice. Robin glanced down his eyes widening in shock. Starfire let out a small gasp of surprise as she too understood.

"No way," Cyborg mumbled.

"How?" Robin asked as he ran his hand through the sand.

Beast Boy lifted the sword he still had clutched in his hand, trying to put together all the questions swirling through his head. "I think it has to do with this metal. It was the only thing that stopped them."

Cyborg examined the blade closely, his human eye squinting as he thought. "I've never seen this type of material before. What is it?"

"It's celestial bronze," a voice broke in, causing all the titans to yelp and jump in alarm. The team whirled around to see the strange goat boy standing close behind them with his hands held up as a sign of truce. He gave the teens a small half smile but his eyes still held a little of their fear.

"Who are you?" Robin wondered aloud, rising from his defensive stance.

"Owen. My names Owen," the boy replied, obviously relieved that the conversation had taken a less violent turn.

"What are you?" Beast Boy questioned, earning himself a stomp on the foot courtesy of Raven. "Ow! What?"

"Don't be rude!" The empath snapped under her breath.

"I'm a satyr," Owen replied, ignoring the two titans' bickering.

"What did you say it was called? Some type of bronze?" Robin asked, getting straight to the point as usual.

"Celestial bronze," Owen corrected, picking up a spear of the ground. "The only material that kills monsters."

Beast Boy let out a snort. "Monsters? Please."

Owen's head snapped up, his eyes glowing a dangerous blue. "You can turn into any animal right? One of your friends is half demon, another half alien. Are monsters in the world so hard to believe?"

Beast Boy opened his mouth to protest but Starfire quickly cut in, speaking for the first time.

"Excuse me. But you spoke of me being half alien yes? I believe you are mistaken. I am fully Tamaranian."

Owen's sharp gaze turned to one of uncertainty. He closed his eyes, placing his hand over his face while shaking his head slowly. "I'm going about this all wrong. I've found five powerful half-bloods and I'm messing it up." The goat boy muttered to himself.

"Half-bloods?" Beast Boy exclaimed, picking up Owen's words with his sharp ears.

"Yes," Owen sighed looking up at the group. "You are all half-bloods, which means you each have a parent who is a god. A Greek god to be specific."

The titans stared at the strange satyr for a moment before they all started to shout at once.

"You're insane!"

"Greek gods aren't real!"

"My dad wasn't a god!"

"You can't be serious!"

"Enough!" Raven shouted, her anger causing a car down the street to explode with energy. The friends were immediately silent, confused by her outburst.

"Let's see what he has to say," Raven explained, her voice lowered a few octaves. She fixed her gaze on Owen who was standing frozen in fear. "Explain."

The shaken satyr took a deep breath before starting his tale. "The Greek gods are indeed very real. Sometimes they will have children with mortals and in strange cases demons and aliens as with you two," Owen began, motioning towards Raven and Starfire. "The child is raised by their mortal parent, whether it's their father or mother. Monsters are always hunting half-bloods, like those hellhounds you just encountered. Us satyrs are sent out to bring them back to Camp Half-Blood, a place where demigods train to protect themselves." Owen stopped abruptly and stared at the titans, praying to the gods that they would believe him.

Beast Boy was the first to speak, his voice shaking with emotion as he clenched his hands into fists. "You're a liar. My dad was a scientist, not some immortal god!"

Before Owen could reply, Starfire let out a shocked gasp.

"Beast Boy!" the alien exclaimed, pointing above the changeling's head. Owen and the other titans responded instantly, their eyes drawn to the space above Beast Boy. Gasps filled the air as the green teen slowly looked up.

Floating in the air was a small globe of gas, swirling in hues of orange and red, like a miniture sun. It's tiny rays of light shown down on Beast Boy, leaving the rest of the group in shadow. A few moments of awe rested over the street, as the sun slowly faded away.

"What the hell was that?" Cyborg whispered, breaking the silence. Beast Boy simple stared at the space above him, an aching feeling forming in his chest, missing the warmth of his own personal sun.

"A sign," Owen muttered. "A sign from the gods. That was the symbol of the sun god." The satyr looked at Beast Boy, a slight bow in the incline of his head. "Beast Boy is the son of Apollo."
