Percy's day definitely didn't go as planned. His day was suppose to be a nice quiet evening in the park, no demigod life, no swords, and no monsters. But of course his day was shattered when he spotted a giant hellhound pinning a girl to a tree. Percy's natural instinct was to run and help, but he didn't want the hellhound to see him.

The hellhound was giant, not like the normal giant, but the bigger than Mr. O'Leary and very threatening. Percy really didn't want to get involved, but despite warning signals going off in his head, he charged the beast.

Percy knew it was a very stupid idea, but what could he do? He certainly couldn't let the girl die because he was supposed to have a peaceful evening, it just wasn't like him. Normally he would blame his fatal flaw, but now that he actually thought about it, most demigods would have done it. No demigod gets left behind.

He was half way towards it when he forgot that he didn't even have his sword. Percy cursed himself in Greek, and while still running, pulled out a 6 inch Celestial Bronze pen.

It might not look like much at first glance, but to Percy it was a reliable, and deadly weapon, something that has always been there for him in his time of need. He uncapped the small ballpoint pen and it expanded into a full three-foot long Bronze sword, Greek lettering was carved into the sides of the pen, the meaning was riptide, the current that takes on by surprise. Percy smiled at the flood of memories that this sword brought with it, but those memories seemed like ages ago.

Percy didn't have a long time to admire his sword, the hellhound seemed to notice that there was another person running at it, and it turned away from the girl.

Percy recognized her; she was a child of Demeter, one of the campers at camp half-blood. He had no clue what she was doing here, but Percy couldn't dwell on that too much.

The hellhound snarled and snapped at the place Percy was standing a moment before.

Percy stumbled to his feet, recovering from his dive. He glared at the hellhound, trying to detect any weaknesses, and then he lunged. The hellhound seemed to know exactly what he was doing a moment before he did it. It brought its massive jaws down on Percy's sword and yanked it from his grip.

Percy bit back a mouthful of ugly swear words as he heard a distinct crack coming from his sword arm. He could tell it wasn't broken, but it didn't help much as pain in his arm flared.

The sword was flung behind the hellhound, impaling a tree. Percy knew that Riptide would always come back to his pockets, but he didn't have that much time. He had to get rid of the hellhound, and fast.

Percy risked a glance at where the Daughter of Demeter once stood; thankfully she was nowhere in sight, which meant that she had escaped—hopefully to Camp Half-Blood.

The hellhound lunged again, and Percy dodged it once more. It snarled at him and tried to snap him in half. Percy jumped back, and ran behind it. He was looking at the one thing that he needed most, his sword.

Percy reached out to grab it, but he was knocked aside by a huge paw and smashed on the ground. The hellhound loomed above him, it red eyes sparkling with victory. It put one large paw on his chest in mock triumph.

The sheer weight of the dog was enough to crush any man, even though he lost the curse of Achilles, Percy was still incredibly strong, but it still didn't feel really great to have a ten-ton killing machine on your chest.

Percy felt his sword re-appear in his pocket, he grinned at its perfect timing. He reached in and grasped its tiny figure; he took the hellhound's distraction as an opportunity and struck upward.

Then the strangest thing happened, the hellhound seemed to notice that Percy wasn't struggling anymore and looked down right before he hit its shoulder, the hellhound leaped out of the way, whirled around and bit Percy's shoulder.

Percy yelped in surprise and tried another sloppy blow. Percy could tell that he couldn't keep this up for much longer, he didn't have the strength to continue. His blows were getting sloppier and sloppier, and not as strong. He could feel his strength ebbing away, releasing itself from his body.

The hellhound dodged, Percy's blow and Percy growled in frustration, this thing wouldn't die! He knew that he had to kill it fast, or it might attract the mortal's attention, or even worse, he might pass out from blood loss, then there was no doubt he would die.

He feinted a blow to the head, then at the last second cut its leg. It wasn't deep enough to kill it, but it couldn't feel good to have a scratch on the leg. The hellhound yowled and looked at Percy with absolute loathing. It threw back its giant head and howled. Percy wasn't sure what it was doing, maybe trying to message its friends, or maybe signaling that it was about to kill a tasty half-blood.

There was a snapping noise and Percy turned his head to look at what might of caused it, which was his fatal mistake. The hellhound took the opportunity and swiped one giant paw on his side. The blow shot Percy tumbling into a brick wall, the building crumbled and Percy's vision was swimming. He could hear yelps of surprise, but he didn't know the owners.

The last thing Percy saw before he blacked out was a redheaded woman in all black.

Tony's day started out rather normal. He defiantly didn't expect a seventeen-year-old kid to be flung into a brick wall right in front of his team (minus Thor, Tony never knew where that gods goes off to), but the life of an Avenger is never silent.

The 'walk' started out normal enough, Tony had shooed everyone out of his building while some of his construction workers fixed the latest problem when he had told Thor that the market didn't have any pop tarts. Thor really does get work up over such little things, which is why Tony loves to tease him.

Tony was talking to Bruce about the latest technology, and how they could do so much better, when he heard a yell. It wasn't the type of yell that normal kids do, like when they're playing with their friends, it was more of an I'm-about-to-die sort of yell, like the person that said it might actually be in trouble.

Tony looked at his team who had obviously noticed the yell as well, and were all in their defense positions. Tony looked at his team and nodded his head, a silent signal that meant; let's go check it out.

Together they crept into central park, going in the direction of the screaming. They stopped by a big red building just outside the park, and what Tony saw sent a chill down his spine.

The fist thing that he noticed was the giant black dog, it was pretty much impossible to miss. It had shaggy black hair, glowing red eyes and pearly white fangs. Tony shivered at the idea of facing that thing.

The next thing that he noticed was the kid that was running around the animal. Tony let his mouth gap when he saw what the kid carried, it was a three foot long Bronze sword. He looked at the Avenger nearest him, Natasha, and whispered in her ear, "That's not normal is it?"

Natasha shook her head, knowing that Tony was referring to the boy with the sword, not the giant dog. "No, I don't think kids carry swords around these days."

Suddenly the kid screamed, and Tony flung his head towards the noise. The kid was screaming in pain as the monster sunk its inch long teeth into his shoulder. Tony winced, just imagining what the pain felt like.

The kid swiped at the animal, and the monster let go. Fire blazed in the kid's eyes and he struck at it with his sword. The monster dodged and snarled so fierce that Steve stumbled backwards, snapping a stick.

The boy turned to look at where the sound was coming from, and then he was forcefully slammed into the brick wall three feet from Tony's face.

Tony yelped in surprise and scrambled backwards, the rest of his team closely followed.

"What the hell?!" Tony heard Clint swear. The kid had been smashed into the wall, breaking the bricks, and he didn't seem to be coming out. Tony snuck a glance at the monster, but it seemed to disappear.

Natasha was the first one to recover; she slowly stood up and walked towards the wall. She gasped and motioned for the rest of the team to come look.

Tony picked himself up and dusted himself off. He started to walk towards the wall, only stumbling a few times. He reached the place where Natasha was standing, still in shock.

Tony peered in through the rubble and spotted a shape. It was the boy they had witnessed fighting.

Now Tony could get a better look at him, he was around the age of seventeen, with shaggy black hair. He was tall, lean and muscular, and seemed to have an aura around him. He had several cut and scrapes, but what stuck out was the bite-mark in his shoulder. It was gushing blood, and didn't seem to want to stop anytime soon.

Tony knew that this kid wasn't normal, normal kids don't put off that much energy, and they wouldn't survive a crash into a brick wall. He glanced at his friends who were all staring at the unconscious boy.

Tony glared his throat, "Um, well, that was exiting." His friends muttered agreements, although some rolled their eyes at his random comment. "But anyway," Tony continued, "What should we do with him?" He pointed at the boy.

"Um," Steve said, "Maybe we should take him to the Avenger's tower?"

"Great," Tony grumbled, "Lets use my house as a medical hospital. This day has been so wonderful."

Yes, I know, a bad time to start a new story, but actually, the first ten chapters basically aren't mine. I adopted this story from Blueh. She kind of ran into a dead end on this one, and what can I say? I contributed to this story, so I'm gonna finish it.

As always, I don't own anything, neither the Avengers nor PJO. I don't credit my self being that much of a genius.
