Chapter 1

Leo

.oO0Oo.

This is too easy. Stupid mortals. Puny security systems. Ha, Leo silently snickered as he continually bashed the mortals responsible for this supposed 'best security system'. Which contained some very classified information. The system he was hacking into, was in fact, none other than SHIELD.

Which stood for Strategic Homeland Intervention, Enforcements, and Logistics Division. Yes, he, Leo Valdez, bad boy supreme, was gracing this facility with his (masked) presence.

As he dove deeper into their files and history any sympathy he had for hacking in was quickly diminished when he saw how they treated enhanced individuals. Which as a demigod with abilities he and his girlfriend fell under their 'danger' category. Then again he wasn't helping his case by erasing him and a few of his old friends from their data base.

But most demigods had enough trouble with monsters and didn't need a ton of agents bursting into their lives. He scoffed at the image of them trying- keyword; trying- to arrest someone like Annabeth, who was one of the smartest people he knew, demigod or no. She'd come up with every defense imaginable. If only she used that knowledge for good- but it wasn't like Leo had room to talk. He'd have to scold her for getting on their sights in the first place. Though he guessed her boyfriend was more likely at fault than her.

She hadn't even noticed, it'd been Piper McLean- yes the Piper McLean- who'd contacted them with this job before she and the others went into hiding.

Thanks to all the inhumans causing trouble in the past couple years SHIELD was really cracking down on anyone with powers that stepped out of line. and since demigods were usually very powerful they had the motto of 'Shoot first, lock up later'. He'd gotten dozens of job requests to erase files from SHIELD. Even from some infamous (well, famous to him) Supervillains.

How they managed to hear about him he had no clue. It wasn't like Leo did many jobs anymore. At least ones were innocent people would die, that was behind him. Now days most were hacking into places for those who paid the most. Calypso went on the most jobs instead.

Piper wasn't even that bad, she was an accidental villain half the time. She didn't even mean to steal she would literally just ask. But SHIELD went after her last month and then she'd had to hurry to Camp to hide out for a bit. Imagine what they'd do if they caught wind of what Leo was capable of... He'd be locked up, killed, or simply used for their gain.

His fingers flew across the keyboard as he took down every defense SHIELD had up, and the constant clicking eventually paid off when... Aha! Here we are! Leo silently cheered as he found all of their files.

There were more he didn't bother reading so he went ahead and deleted all of their information on his old friends.

As he finished up and made sure his presence couldn't be traced back here, he forgot one thing...

Classic, unhackable, paperwork.

.oO0Oo.

Leo blinked repeatedly as he cleared the sleep from his eyes. The smell of food from upstairs elicited a growl from his stomach. He yawned, stretched, then stood. His bare feet slapped on the cool floors as he trudged his way up from his basement 'office'. As in Calypso got tired of his constant typing and shoved everything into the basement in impressive time with her spirit Nymph powers.

"Mornin'," Calypso said with a smirk, "or should I say afternoon?"

Leo just grunted in response and trudged over to their custom coffee machine. He hit the 'nectar' button. Which added the godly drink to the bitter caffeinated beverage. When his 'Repair Boy' mug (gift from Piper) was filled he plopped down in his spot at the table.

Their kitchen was Country styled and reminded Leo of the one from when he lived with his mother in Houston. The dining room table was a light brown with an accented cloth over it, the kitchen bright and lively, a couple of small clay pots filled with herds and seasonings for cooking sat in the windowsill. Outside in their minute typical New York backyard was a garden filled with mortal plants. He took small sips of his drink and ate some of the food laid out on the table, which was a cheesy pasta of sorts.

"You're lucky it's the weekend," she shook her head at her boyfriend. She also noticed the bags under his eyes- something that happened when something stressed him out and he didn't sleep.

"I was up erasing SHIELD's files on us and the others. Some people we know caused a bit of trouble- again- and somehow blew up another monument- again. So then they were the main suspects while they were after something," he explained then stuck out his tongue at the end. It didn't matter if he he was twenty-one or five he was just as immature as ever.

"What'd Jackson do now?" She asked deadpan, knowing it was usually old flame that always caused trouble.

"Actually it was the effort of our dynamic duo, the good ol' Percabeth. Or at least that's what Beauty Queen said," he smiled at the nicknames as the coffee and nectar began to take the edge off his generally crappy attitude. Calypso scoffed and took a bite the sandwich she'd made herself.

Officially as 'normal' as he could get with his astounding four hours of sleep, he stood. "We should probably head over to the workshop and get the work done so we can relax. At least until we get another job."

Calypso pursed her lips but nodded, she'd rather be tending to her garden but she also loved the workshop. And she was rather bored. "Let's get going," they both stalked off, heading towards their pride and joy.

.oO0Oo.

They arrived at a the worn down garage. It had three main parts. The area where they repaired cars, the front room where they worked on other machines people brought in, and the backroom. Or, what most people thought was the storage. It was actually their weapon building room.

It was Leo's favorite due to the fact he could blow things up and not be yelled at. The whole place was one of Leo's favorite things in the world. It reminded him of his mother's workshop. The smell of moter oil and rubber took his mind back to his happier days. But after Leo had been taken away he never saw it again. Only having fond memories of his old life.

They both went to work. Skillfully dodging around each other and working together like a well oiled machine as they finished up the weekend's work. Eventually they got bored with the mortal devices and started making the mythical weapons made of celestial materials. One's both camps and demigods would pay dozens of dracmas for.

At SHIELD

.oO0Oo.

Coulson was confused... No, worse than that; he was concerned. How could over ten files disappear with no trace whatsoever? He had no clue. There were no clues.

Except... What files were missing? It was a stupid thing to obsess over, he had more important things at the moment. But that was with SHIELD. There were countless others that could investigate and deal with this. An idea popped into his head, not a good one, but an idea nonetheless. But they could deal with it.

He sighed and rubbed his eyes. This was going to be a long day if he had to convince them to help. For now he just had to convince Director Fury. Silently flexing the prosthetic hand he reached out and snagged some workers coffee. Who just looked back at him questioningly. He was going to need it more.

.oO0Oo.

"Fury, what is-"

Fury cut off the purple clad man, Clint or Hawkeye, by raising his hand to silence him.

Natasha sat next to Bruce- who was asleep with his head on the table- with her feet propped up on the table, pointed away from the sleeping man. Steve sat silently but there was curiosity in his eyes as they waited. Clint Barton was sharpening his arrows and grumbling at the fact he was here.

It was currently two in the morning- as it had taken all day to figure out what files were erased and to find the paper files- and they'd all been called in. When they argued he'd said it was an emergency... Apparently they needed to work on response time because they were still short one red and yellow member. As for Thor, he usually would be here but he was on Asgard at the moment with some sort of emergency.

Suddenly the door burst open making everyone but Fury, Natasha, and Bruce jump. Tony Stark aka Iron Man cleared his throat and calmly sat down in his chair inbetween Natasha and Bruce.

"Can we start now?" Clint asked- or whined- impatiently as he retrieved the arrow he'd dropped and returned it to his quiver. Bruce, who had been jostled awake when Tony decided he wanted to sit to his right, opened his eyes and lifted his head up to listen.

"Yes, now that you're all here," he glanced at Tony who just smirked.

"What's the emergency?" Natasha asked talking for the first time since they'd entered the room and getting to the point.

"Last night a number of files were deleted from our database on possible enhanced individuals," he pulled out the files and set them on the desk in front of them. "A few of them are suspected terrorists and have been involved in mysterious circumstances and accidents. We have our main suspect, Leonard Valdez. Who is a genius with machines and computers."

Tony made a 'Psh' sound as he opened his file which contained a picture of a young elvish looking Hispanic guy who was smiling to something off-camera.

"Don't underestimate him, Stark. From the things I've heard he could be better than you," Fury aimed his words directly at Tony with an exasperated look that said 'don't-let-you're-ego-mess-this-up-for-once'. Not many people can make Fury annoyed or express emotions, and yet here Stark was...

"He's also been on the down-low for the past five years. He was in an accident when he was young, his mother was killed and that's when he was put on our radar. Then his mysterious girlfriend showed up out of the blue (hahaha you have no idea) when he disappeared for two weeks."

"Where is he?" Clint asked, skimming the pages and stopping on one picture of Valdez with a face splitting grin with his arm around a caramel skinned girl who was laughing at something that was said. Overall they looked happy and not really evil-ish. "'Cause this guy doesn't look like one who'd go for evil liars and shit. Too smiley..." He muttered the end and pointed to the picture. Tony looked deep in thought, the other with similar expressions.

"Clint," Fury snapped, "we are dealing with an unknown, possibly super-powered human. Who is right here in New York," Fury answered. "He owns a repair shop and garage to repair all sorts of machines and cars. Go there tomorrow and investigate."

.oO0Oo.

Okay so I've had this idea for a while now, plus a PJO-HoO/Marvel universe would be amazing. Plus Leo is awesome and I always love fanfics like these (honestly there isn't enough PJO/Marvel fanfics in my opinion) and my motto is 'Write what you want to read'. So I'ma be evil bwahaha. And write an evil (not cliche) Leo Valdez! Even better! A vilain for hire Leo! If you don't like I can write a cliche story about one of them being related to him- I might just do that anyways. Lol

Warn me if this shit is OOC (out of character for you new fanfic readers) 'cause I'm still new at this.

And finally, last announcement (I swear): lot of events and things are different in this. Most are the same. Monsters still attack but demigods can use computers and phones. Mist does not exist. The war did not happen and the camps have been at peace with each other since forever.

And there is a slightly different backstory for Leo (sorry but our usual Leo wouldn't be a villain). But this story is mostly about Leo's experience with the Avengers. As much as I love Thor in PJO fanfics (especially as a fanboy towards demigods) he won't be in here much.

Time-line is before Age of Ultron.
