4 years. It's been 4 years since… the incident.

For Perseus Jackson, they've some of the best and worst moments of his life. But what is he doing now? Percy is now a Level 9 S.H.I.E.L.D. Agent/Assassin code-named Spectre. Named accordingly due to his mysterious past and the way he runs his ops. Quickly becoming one of the top agents of the agency. He is also now fluent in 6 languages: English, Ancient Greek, Modern Greek, German, Latin and French.

Since the incident Agent Jackson has lost his abilities that came with his birth, but they couldn't get rid of the ichor present in his system, and as such still has faster than average reaction times and his dyslexia is almost non-existent, but still able to read Ancient Greek perfectly. Along with the removal of his water powers, his accuracy for the bow and other ranged weapons has increased drastically, and as such he now carries two standard pistols each strapped to one leg and also carries a military tactical knife strapped on his belt just above his arse. Percy lost Riptide when he was cast out of the Greek/Roman world and thus had to start again.

Currently he was walking towards Agent Coulson's office, with a stoic expression. Everyone moved out of his way like a parting wave; he never smiled anymore, or at least never to people he didn't completely trust, which was only a few.

Knocking only once, he pushed open the door to Coulson's office. And it was a mess; paper everywhere spewed along his desk in no organised manner… at all.

"Ah Agent Jackson, what can I do for you?"

"I've been told by Director Fury that you have to take me and Agent Barton to go to project Pegasus to 'keep an eye on things'."

"Why?"

"I don't know Phil, but Directors orders." Replied Percy "Although I have no clue why I'm going; I can understand Barton, but why me?"

"Because Percy, you have dealing with the… supernatural."

Percy sighed before slowly rubbing his hand down his face, "I'll give it two weeks before I start destroying the base." He stated.

Coulson laughed in reply "Try a week. Max."

"Wanna bet?" Coulson nodded "I'll go find Barton to tell him the news. No doubt he's with Natasha at the moment. And try to get some sleep, gods know you need it."

Percy turned on the spot before walking out the door, but not before hearing Coulson call out "You guys are always together, we can never seem to split you to up."

Percy gave a short laugh as he continued down the hall, which gave him a few weird looks; he never laughed, he's heartless isn't he?

He found Barton and Romanoff in the gym, sparring on the mats in the corner. Usually the pair would have a small crowd watching them but there was no one else in the gym at the moment, making the Spectre the only audience member not that either noticed, there was a reason why his code name is Spectre. He watched as Natasha launched a roundhouse kick that Clint blocked with his left hand while launching a punch toward Natasha. Natasha then grabbed his arm with both hands and judo flipped Clint over her shoulder, ending in a lock that Clint just couldn't break.

Clap. Clap. Clap.

The sparring partners looked over to the sound where they found Percy with a smirk plastered on his face. Natasha unhocked herself from Clint and stood up before helping Clint up himself.

"What's this now Clint? Fourth time in a row?"

"Shut up, Percy." Clint dead panned, while Natasha smirked. "I'd like to see you beat her."

"Oh, he does. Almost every time unless I get lucky." Natasha casually stated. "I thought you knew that already." Clint looked between the two with a shocked expression and then threw his arms up in the air in exasperation.

"Anyway what are you doing here Percy?"

"We got a mission. Got to keep an eye on Project Pegasus." Percy said glumly.

"Just us to?" Clint asked. Percy silently nodded "When we leaving?"

"Two hours, better suit up otherwise your leaving without it." Clint then scampered off out the door toward his quarters leaving the Jackson and Romanoff to themselves.

"Hey Tasha." Percy said as he closed the gap between themselves.

"Hey Perce." Natasha replied as she put her hands on Percy's hips. They both closed together for a short kiss leaving them both smiling at each other. Natasha was one of the first people Percy knew when he first joined shield and Percy was more closed off than her, which greatly surprised her and as a result, she wanted to get to know him. Through Romanoff Percy met Clint and very quickly the trio became inseparable. As they worked more closely, Natasha and Percy found themselves liking each other more and more and as he was a lower level at the time, they both started dating.

When Percy became a Level 7 Agent, S.H.I.E.L.D. could not break up the pair and as a result, they are the only Level 7 or higher operatives in a relationship not that it's on record, much to their liking.

"I'm heading off to Russia for my next assignment so I'll be out the country for a while." Natasha stated.

"And I'll be on a boring op, at least you're out the country. I have to make sure scientists don't break something important." Natasha laughed.

"Well, you better get on and pack, and as do I. I'll catch you later." Natasha said, much to her reluctance. They kissed on last time before replacing their stoic expressions and walking out the door, off to their quarters.

-Line Break-

Percy Jackson and Phil Coulson walked up to the helicopter pad which the Director of S.H.I.E.L.D., Nick Fury and Agent Hill stepped out of a pitch black helicopter and walked the rest of the way to the two agents, his trench coat bellowing in the wind created by the helicopter.

"Agent Coulson! Just what exactly is going on?"

"It's the tesseract, sir. It's behaving… oddly."

"Oddly?" Fury mused as the trio walked along, Fury and Coulson next to each other and Jackson covering the rear. They quickly made it to the room where Erik Selvig was working on the tesseract or what Percy and Clint have dubbed it 'the shiny box thing'. "Where is Agent Barton, Jackson?"

"In his nest." Percy smirked while looking up toward the roof.

"Get him down, now." Percy smirk dropped as he contacted Hawkeye. Who quickly jumped down from the rafters to Percy, who gave him a lop-sided grin.

"Doctor Selvig!" Fury called out "What is going on?"

"I'm not sure, it's not responding to anything." Selvig replied.

"So why don't you turn it off?"

Doctor Selvig just looked at the one-eyed director "Because it just turns itself back on." Confused, the Director continued to watch as the scientist team worked on the tesseract.

"Agent Coulson, I need you and Agent hill to go up top, keep an eye on things." Wordlessly they both departed back the way they came, leaving the Director with the two assassins. But Percy suddenly Percy spoke up.

"The tesseract is supposed to be a gateway, right Doctor? Don't doors open up from both sides?" Selvig turned round to Percy before widening his eyes, but before he could reply, a light beam fired from the tesseract and connected with the far wall, opening up a portal and a single man stepped out.

He was wearing fine green and black clothing with a sceptre in his hands and a weird helmet almost moulded to his head.

"Sir, put down the sceptre." Fury commanded who just looked at him oddly.

"Now why would I do that?"

"Who are you?"

He gave off a small chuckle but Erik answered "HE's Loki, brother of Thor!" he did not like that answer.

"Now what do you want? We don't want to fight." Fury continued.

"It wouldn't be much of a fight if it's a boot squashing an ant."

"You calling us ants?" Fury asked, almost bewildered. Loki just smirked. He then continue how to ramble on about how he was going to take over the world and there was no one there to stop him, but Percy zoned out. That is until Loki placed his sceptre on Clint's chest. Percy and Director Fury watched as his eyes turned to a navy grey and he proceeded to do that to Erik Selvig as well.

He finally came up to Percy and tried to do the same thing, but this time, nothing happened.

"What? How is this possible?" Loki asked allowed but Percy just smirked.

"I really, really, don't like people trying to take over my brain." Before punching Loki directly in the face. Before Percy or Fury could act anymore, Selvig grabbed the tesseract and walked off with Loki just as Clint shot Fury in the leg, crippling him. Percy knocked the gun out of Clint's hand and punched Clint, but he missed. Instead Clint punched Percy in the side of the head, knocking him out.

When Percy came to He was inside the helicopter with Fury, Coulson and Agent Hill.

"This is a code 7" Fury stated "We are now at war. We need you to get hold of Agent Romanoff and get Doctor Bruce Banner."

"The hulk?" Fury just nodded.

-Line Break-

"Put the girl on the phone." The man on the other end started asking questions but Percy cut him off "I have a B-22 bomber 2 miles out of your position, by the time you're in the lobby, you'll be dead." He paused to let that sink in. "Now put the girl on the phone."

"What do you want Jackson."

"We need you to come in. The avengers' initiative is activated."

"I can't come in now, I'm getting all of the information from this guy." Natasha replied, slightly annoyed.

"Percy paused, really not wanting to give this info away "Barton's been compromised." He heard a sharp intake of breath.

"Let me put you on hold." He waited while he heard Natasha completely screw over the thugs before she came back.

"Right, so who am I getting?"

"We're getting the big guy."

"Really… Tony Stark?" Natasha let out a frustrated sigh.

"N0, Coulson's got Stark, we've got the big guy, Doctor Banner."
