This will be an extremely AU world. I don't have any plans to bring in the movies/shows as the total background of this story, I may mention things that have happened in them however, but don't expect the characters to be totally the same as they are in the movies/shows, nor their backgrounds. In the case of characters with multiple versions, I'll pick whichever was my favorite XD Heck, I might even bring in some characters that are dead in the shows/movies, but will be alive because I like them or they fit or whatever (just pretend they pulled a Loki XD). I will be bringing in Percy Jackson, as it does tie in with my other story, The Reluctant Avenger. Wish we could pick more than two categories for crossovers.

Twelve year old Athena's deep green eyes sparkled with excitement, she was finally being adopted! The sun shown against her reddish brown hair as she hurried to get ready for the big day ahead of her. She quickly made herself a vow that she would never let her new family-to-be down.

4 Years Later

Thea woke with a start, her head pounding as she tried to focus. Her brother's modulated voice broke through the fog in her brain as he asked "Speedy, are you okay?" Her eyes began to focus, and she swiftly took in her surroundings as she followed the sound of her brother's voice. She saw him being held by a man who also had a bow strapped to his back, though her brother was without his, and a red headed female was reaching to help her sit up and then to stand. "I'm fine Arrow." She replied, spying not only Spartan but Flash as well being held. "What's going on?"

The four were being led through corridors at this point and a voice said "For one thing, you could drop your code names and tell us who you really are, not that our facial recognition software won't be able to do so soon enough, even if it does keep getting blocked from some unknown source." The voice belonged to a black man with an eye patch on one eye, who was standing in a huge room which they were led into. It was all Thea could do to keep from smiling, Felicity could always work wonder with a computer and by now she must have alerted some, if not all, of their other friends that something was up.

Just then, another man came in whom was looking at a data pad as he said "I have to admit, whoever is blocking us has me stumped." "Never thought I would hear those words coming from you." The red headed woman beside Thea said. "Enough sarcasm Natasha, whoever it is I will prevail against them!" the man looked up and Thea's eyes widened as she recognized him, it was Tony Stark! By the looks of everyone's faces, besides her bother, they did too.

Oliver may not have been on that island the whole time, but he sure didn't keep track of all the news either. She remembered the big scene Tony made about being Iron Man at a press conference. If Tony Stark was here, that must mean that the persons holding them were whoever had brought the Avengers together, because no matter how much Tony claimed it was him, Thea knew he didn't work well enough with others to do that. "What do you want with us?" Oliver asked to which the man with the eye patch responded "You vigilantes may think you are doing good, but wherever you try to help you just make matters worse and you just end up losing people along the way."

Pained expressions crossed all of their faces at the thought of Laurel, followed by Oliver practically spitting out "The Black Canary died protecting our city." 'Well not mine, I'm not from there." Barry responded, vibrating so his voice came out warpy, "But she knew what she was getting into and she died so others could live. If not for us "vigilantes", Dark would have destroyed the world, metahumans would be over running the country at the very least by now…" "All of which the Avengers could have handled." A female agent standing at the guy with the eye patch's side interrupted him.

"What makes them any different from us?" Diggle asked, "How do you know we don't report to an organization just like the Avengers obviously do?" "I would have heard about it if it was so." The man with the eye patch replied simply. Meanwhile, Tony had grown bored of the proceedings and was working on some formula that was floating above his tablet and Thea watched as Barry's eyes locked onto it. He frowned before he asked "What are you working on, Mr. Stark?" "Oh just some little science fair thing that you probably wouldn't understand." Tony replied without looking up.

"Why would you want to time travel?" Barry asked, bringing everyone's attention to him, including and especially Tony's. "You can understand this?" Tony asked, a bit of surprise in his voice to which Barry responded "You're not the only genius who can suit up." "What do they call you?" Tony asked, trying to distract everyone from his project, which he quickly switched from and back to the face recognition software. "The Flash." Barry replied. "Why, do you go around flashing people or something?" Tony retorted "Pretty sure you could go to jail for that, so whether or not you're a hero is debatable."

"You're trying to distract us Stark. Why are you working on time travel?" The guy who apparently was in charge asked. "Just think of how useful it could be when we are fighting the bad guy, Fury. If we lose, we can just go back and do it over." Barry's eyes sparked, quite literally, before he angrily said "You shouldn't be messing with things you don't understand. Tony's own eyes flashed, not quite so literally, as he responded in a fiery tone "How else are we supposed to learn about things?" "Flash…" Arrow said in a cautioning tone, to which Barry gave him a hard stare, before taking a deep breath and replying "When the bad guys can take that knowledge and use it for themselves, that is when it becomes a problem. And even a single act can change things, and not for the better."

Tony perked up at this and he stated "You know something about this, on a personal level don't you." "If you're thinking I am going to help you, you are wrong. Think about it, if you are right and I do know about this personally, then I know what I am talking about when I say don't mess with things in the past or the future." Barry responded softly. Suddenly a furious beeping noise came from Tony's machine, causing Tony to look down and then growl, "A virus?! Seriously?!" Natasha smirked and asked "Problems Tony?"

Before Tony could respond, his face recognition software was replaced with a video of a kitten, causing him to toss the thing in frustration. "Okay, I admit defeat but…" "Unknown person approaching the carrier sir." Interrupted the female agent beside Fury. "What kind of aircraft is it Hill?" Fury asked, to which Hill responded "No aircraft sir, just a human." An image was projected from somewhere showing the live feed and Thea smirked a little at the sight of Supergirl. "She's heading right at us sir." Hill informed him, a little nervousness entering her voice. Fury didn't respond as Supergirl got closer and closer. He was sure she would veer off, but ended up being surprised as Supergirl not only hit the ship, but penetrated it.

Alarms started blasting and the sounds of guns being fired filled the corridor that was just outside the door they had been led through just a short time ago. Natasha reached for her weapons as Tony started summoning his suit to him, just seconds before Supergirl knocked down the door. Agent Hill emptied her gun, multiple shots striking Supergirl only to bounce off her. She broke Thea's bonds with ease and had just moved onto Barry when Tony's armor finally reached him. He sent a repulser beam at her, which pushed her back. But with a shot of her breath she froze him in place, his suit struggling just to keep him warm. Natasha came at her with everything she had, but Supergirl tossed her into Hill and Fury like she wasn't even a problem.

The agents who had brought Barry and Diggle in fell back as the guy with a bow reached for an arrow. He couldn't seriously think that one of those could take down a girl who was deflecting bullets could he? Thea shouldn't have been surprised to find out her brother wasn't the only one that had special arrows, for as the arrow struck the wall beside Supergirl it exploded with an ear splitting sound. Barry and Supergirl seemed especially effected by it, as both went down holding their ears, and even Diggle, Thea and Oliver held theirs.

The bowman rushed forward with a pair of special clamps, hoping to get them on Supergirl before she recovered, but he had forgotten or hadn't noticed that Thea was free and she quickly pinned him down, holding him there as the two sides recovered from each other's attack, having seemed to have reached a stalemate. "Who in the Sam Hill is this?" questioned Fury as he staggered to his feet as at the same moment Arrow said "Good timing Supergirl."

The guy with the bow said from under Thea's hold, "Well that one is aptly named." "I'd like to see her and either Steve or Bruce go at it." Hill muttered under her breath. Barry, ever the diplomat, said "Okay, why doesn't everyone take a deep breath and we can talk about this calmly." Supergirl by this time had freed all of her friends and all were standing next to each other facing the other group.

"Sounds logical to me." Said Natasha. "How about we start with your real names, after all you know pretty much all of ours at this point." Added Fury. The friends all looked at each other and nodded. Supergirl spoke first, "My birth name is Kara Zor-El, but I was adopted so my last name is Danver now. You probably won't find me in your search, as for one I am not from this earth, I'm from a planet called Krypton." As they processed this information, Barry removed his cowl as he said "I'm Barry Allen, I'm a metahuman."

"And I'm Oliver Queen" Oliver said, turning off his voice disguiser as he pushed back his hood and took of his mask. "I'm his sister, Thea Queen." Thea said as she copied her brother's movements. "John Diggle."John said, removing his helmet. After a moment of silence, Hill said "well that was easier than expected." "What's it going to take to make you guys stop what you are doing?" Fury questioned. "Nothing will make us stop. We have given up to much to do what we do, to protect people that you don't have time nor the manpower to help." Oliver said.

"You can try locking us up or keeping us down, but we will get out and we will keep fighting for our homes and friends." Barry added. "Or you can just let us go, we can go our separate ways and keep doing what we've been doing, helping people. We have done nothing wrong, at least not wrong enough for you to keep us here. Yes, we made mistakes, but we always tried to correct them when we could." Kara said.

Fury rubbed his eyes and muttered "This is going to be another Percy Jackson isn't it." Then he stared hard at the group as he said "I'm going to call in the other Avengers, we will discuss this and decide where we will go from here, are you willing to comply with this? I mean we will use force if necessary, but I really don't want to go round 2 with ya'll right now."

The five of them once again looked at each other before Oliver nodded and said "Agreed." "Good, now why don't you make yourselves comfortable while we wait?" Fury said, as he headed off to call the others in.

It didn't take long for everyone that was summoned to show up. They were introduced by their super hero names to the five friends, letting them decided if they were trusted enough on a personal scale to know the others secret identities. Ant-Man and Spider-Man were the first to do so and Thor and Captain American were already pretty much known to the group, so their introductions were kind of unnecessary, though Cap did his just in case. Bruce came as himself so he told them that his alter ego was the Hulk.

Wasp had joined Ant-Man on this adventure and it was she and one called Storm Bringer that held back their real identities, at least until they knew why they were called here they said. Falcon hesitated, but when Cap did it, he did as well since he trusted his judgment. Black Panther was unable to come as quickly as the summons had come out, but he too held back his identity until he knew more, as he joined them via a hologram.

Fury called the meeting to order and everyone present sat down while the Black Panther hovered in the middle of the table of the conference style room they had commandeered for this purpose. Fury told them who the five were, their superhero identities anyways, and why everyone had been called here. Storm Bringer was the first to comment, "So basically you called us here because these guys aren't in your control." The statement annoyed Fury, but he replied "No, I just don't think that people with their powers and abilities who are out doing what they are doing should be allowed to do so without someone to answer to."

"Someone being you?" Peter Parker asked, knowing that it would anger Fury, but unable to hold back the remark. "It doesn't have to be me, to be Shield, but that kind of power shouldn't go unchecked." Fury said, anger showing in his one good eye. "Well, I'm not from this planet, well I am, but not this one, and where I come from I do report to a group called the DEO." Kara spoke up. The ones that hadn't been there earlier showed their confusion at her comment, while Tony asked "How do you get between these different Earths?"

"That's on a need to know bases." Oliver said. To soften the blow as well as to hopefully keep them from pressing further, Barry added "More like the less people who know the better, don't want to destabilize walls anymore then we have to." Barry didn't think that that would really be a problem, but better for them to think it. The explanation seemed to work for now, as Fury said "Well that's all well and good, but what about the other four?"

"Well us three work with Argus sometimes. I guess you could say they keep tabs on us." Diggle said. Fury muttered under his breath about Argus, before glaring at Barry. "And you?" "Sometimes have been known to work with Argus, but really it's the Speed Force itself that keeps me in check, trust me, you do not want to mess with it." Barry said as he shuddered. With that everyone at the table all looked at Fury as Bruce asked, "Couldn't you have figured that out all on your own? Why did you call us here?"

Fury frowned and said "While I can't speak for the DEO, what the heck does that even stand for?" "Department of Extra-Normal Operations." Kara answered. After staring at her for a minute, Fury continued, "Argus is supposed to tell me about any supers they encounter, which means the other four of you should have been reported about to me, it would have saved us all this headache."

"So are we free to go?" Thea asked. "No, first I have to confirm with Argus that you do indeed report to them and then…" Alarms started blaring all over the ship. "What now? Did you call for more help?" Fury asked, glaring at the five prisoners. They all shook their head as Fury yelled, "Hill, report!" "There's a lot Fury, villains are popping up everywhere, causing chaos, and some that are either dead or are still showing up on cameras as being under lock up!"

"Zoom!" Barry exclaimed. "Zoom?" questioned the Wasp. Barry nodded and said "Zoom is an old enemy of mine, I destroyed him, but the thing about speedsters is they can actually create different time lines like nothing, or pull themselves from another point and while they will be hunted down by the Speed Force, if they can stay ahead of it, they can live. There is a lot more to it then that and other possibilities, but that's the short version for now. Anyways, aside from taking themselves from different points in the timeline, they can take others as well. He probably grabbed as many villains as possible and brought them all to this point in time. Think of it, some of these guys were hard to defeat on their own. In such a large group…"

"It will be ten times harder." Storm Bringer finished. "Harder, but no impossible." Said the Black Panther. "Since you know so much of what's going on, for now we'll have to put aside any differences, etc to get this situation under control." Captain America said. Barry and the others nodded, but they wondered just what they were getting themselves into.
