A/N: I'm back guys and with a new story that I feel really confident about considering that I have it planned a good amount into the future already :) Either way, I've become a big fan of Young Justice lately after binge watching the series and in all honeatlh I couldn't help but make an OC. This idea had been on my mind for a while now and while I was hesitant to do it at first considering I'm writing a book series at the moment and I should really pay more attention to that, I'm doing this instead. But I hope you enjoy and please comment and favorite the story. Constructive criticism is welcomed.

Prologue

Green eyes looked on curiously at the duo in front of her, one very familiar tall figure covered in darkness and a younger boy, close to her age staring right back. They were like light and dark to her, polar opposites. Batman was made for the darkness, it clung to him and embraced him, but the slightly older boy was like the light to his dark, with a black mask covering his eyes and a brightly colored suit of green, red, and yellow standing out on his rather frail and skinny looking body. Was this really the boy wonder standing before her? The same one known for being Batman's sidekick and had saved dozens of people from the villains of Gotham?

"Batman?" Robin questioned, looking curiously between his mentor and the unknown girl before him who looked a year or so younger than himself. "What's she doing here?"

At the question, the Dark Knight looked down upon his protege- his son and withheld a small sigh. He wasn't exactly sure himself what she was doing here or what had been going on through his head when he had taken it upon himself to take care of the girl. But guilt had carried him to do the act, to take on the daughter of his old friend who had died recently and personally requested he do so had anything happen to him- a constant threat considering he was a hero, a well known one with enemies.

And just as he had feared, he had been killed in the act of duty, leaving behind a small nine year old who didn't seem like she could harm a fly and who he had decided to take in, not as a ward but rather to simply care for her in his absence. "She'll be staying with us for the time being, Dick." Or atleast until the other League members took their turns watching over her like agreed.

At the mention of his civilian name, the said boy knew he was serious and was in no threat of his identity being exposed to her. So instead he glanced at her curiously and took in her dark inky hair and light skin complexion. She was cute- he supposed- in an innocent way that made her seem almost angelic. He grinned slightly. "Well? You gonna say something or cat got your tong-"

Feeling a rather small but strong grip suddenly on his chest, Dick wasn't prepared to suddenly be flipped into the air, rather measly considering the girl's limited strength but nonetheless impressive to the ten year old as he found himself staring up into the ceiling of the batcave. He let out a large grunt, looking up to the small figure and she towered over his body. "I don't appreciate being taunted."

"I understand where you're coming from," Batman had begun, grabbing hold of the girl's shoulders as if fearing she may strike again but still looking highly amused as he looked at Dick, "but I would prefer if you wouldn't fling around my partner as such."

"Is he really the boy wonder?" The girl had questioned just as the dark haired boy had begun to pick himself up. "He doesn't seem like much."

Frowning, Dick noted she was rather blunt and felt his temper getting the best of him. "Like you should be talking!" He said, furrowing his eyebrows behind his mask. "I don't even know who you are."

Her bright green eyes looked at him playfully at the question. "You're annoying- I don't need to tell you."

For a moment Dick looked almost mortified, looking at the girl wide eyed through his mask and frowning. That had been their first meeting, and one of many along with other members of the League and their sidekicks.

The girl did always know how to make a memorable impression.

Mt. Justice

July 20, 12:21 pm EDT

Dick Grayson was no stranger to Mt. Justice- for him it had always been a second home when he could manage to escape from Batman and Gotham, a place where he could relax and be himself. He had always considered the place like a sanctuary at one point, somewhere he could bond with his friends and go on missions like it was the most normal thing to do. But things had changed. It had been a month since his last visit to the place- maybe two considering it had been blown up earlier before- and slightly shorter since he had last visited the team.

A month since he had taken a break from his work as leader and Wally's death.

Throughout the night he had been terrorized with nightmares of his best friend, and even had remembered the others he had lost, the wound of Wally's death still fresh. The weight of such was heavy on his chest that morning and he had not managed to get much sleep the night before- not specifically the best way to start off his first day back. Stepping through the zeta tube of Mt. Justice, the dark haired hero felt the nostalgia of his old base. He saw memories that were no longer there and the faint voice of his deceased friend, still ringing in his ear. Perhaps it had been too early to come back.

Fully suited up in his dark outfit and mask donned over his striking blue eyes, Dick Grayson no longer existed. Nightwing was in his place, the ex leader of his old team and an important part in it. For years he had loved the thrill, the rush of being someone else and having a new name- of fighting the crime of Gotham and then with a team saving the world. But now, he wasn't sure if he still did. Instead he found himself hiding from his second persona, barely putting on his suit or patrolling Bludhaven like before.

The loss had been affecting him more than he had liked to admit, and he had stubbornly come back to the base in hopes of pushing aside his feelings. It had been too long, like Batman had mentioned when he came to him, in need of assistance in an upcoming mission. Besides, after all, the team needed him.

Stepping foot into the newly renovated Mount Justice, Nightwing took his time to look around- to notice any changes that would have been missed by the naked eye. But instead he found none, and it seemed as if nothing had ever happened, that their fortitude had never been blown up and that they had taken residence into the Watchtower. At the time, it had been a privilege, an honor for them, something that the team had deserved and proven to their mentors, having accepted it immediately when offered to them after the final mission before he had left.

They had deserved it after all. He knew and so did the League, but from the last time he had visited- nearly two weeks ago- they had still been in the watchtower and plans of rebuilding Mt. Justice had just been mentioned. The watchtower was of course a privilege they had enjoyed, but the mountain had been their original home and the team had yet to give it up. It had been built in a matter of a week, and he had yet to come and see it, drowning himself in his work and upcoming college in only a month. Nightwing had been long forgotten by Dick himself for a good amount of the time.

Walking further in and seeing none of his team around, the tall male made his way throughout the base, towards where he knew they would be- the briefing room. It was after all the reason he had come back earlier than expected. A mission had come up that Batman had personally come to Dick for, in need of him being apart of it. He could never say no to him as it was and he would admit that a part of him had missed the others and the thrill of a good mission. His mind flashed back to the day before when the Dark Knight had come as Bruce to mention the mission to which he had agreed with slight hesitation. Throughout the month he had barely made time to see the team, only having Barbara, Artemis and Tim as occasional company when they would come to visit him. However, Bruce was the worst, checking up on him regularly like any overbearing father who didn't know how to show his emotions properly. His answer to dealing with it was practical stalking and Nightwing found it rather funny. Besides, in hindsight, he missed the action.

Making his way down the silent corridor, Nightwing could make make out the sound of voices and laughter, heading towards the noise. Like he had imagined, the rest of the team was in the briefing room, twelve of them in total as he took note that a certain Atlantian and blond were missing. Inside, Beastboy ran throughout the large room, Jaime chasing him in his civilian clothes looking annoyed despite the slight smile on his face. Static was watching the duo in amusement, every once in awhile catching hold of the object that Jaime wanted before throwing it to Kid Flash- the new kid flash- who taunted and laughed at their game.

Karen was with Mal sitting down on one of the couches, one arm around his girlfriend as she read a book on scientific formulas, the larger male paying attention to the tv in front of him. Conner and Megan were near them, trapped in their own personal bubble all while oblivious to a sulking Lagaan as he eyed their exchange. Tim and Cassie were training or what would've passed as training- with flirtatious comments and skin contact that lasted longer than usual for a fight, much to Nightwing's amusement. Batgirl was near them with her back to the opening, her ginger hair shining distinctively against her dark suit as her fingers worked like water against a hologram screen.

Everything seemed the same, just like he had left it despite a few new and missing faces. It didn't seem like he had been gone for a month straight and at the thought he felt something stir in him ever so slightly. For a moment he simply watched, content with taking in the moment and getting ready to face his team.

It didn't last long.

A gentle pressure had landed on his shoulder and out of reflex he had grabbed hold of it, turning swiftly to nothing- before his eyes had turned down and he was met with a shorter figure. Nightwing looked down into two very familiar brown eyes, the slight Asian descent obvious in the slant of them. Blond hair pulled into a ponytail was attached to a pretty face, full lips pulled back into a slight smirk. A tiger like mask was attached to her equally orange and black body suit, and body armor covered her lithe yet muscular form. Artemis smiled. "Nice to finally see you came around."

"You know I couldn't stay away for long." He said, dropping her arm and matching her smile with his own and he looked down at his friend. "It's good to see you though."

"Now don't start getting sappy on me Grayson. I just saw you a week ago." Artemis reminded him, nudging him slightly as he chuckled slightly. True to her word, she had just met up with him a week ago at a coffee shop near his house, and the week before, and the week before that also. They had seen each other throughout the past month more than ever before, an anchor to each other when the pain would get too hard, and the loss of Wally would seem to drown them too deep. If anyone could help them, it would be each other- the girlfriend and bestfriend to the deceased speedster.

Moving towards the door, the blond archer beckoned for Dick to follow with a tilt of her head as she walked through the entrance, Nightwing trailing. It was cool in the room, to help escape from the scorching July sun and at their arrival heads began to turn towards them. Cassie and Conner were the first to notice the duo, catching sight of the them and alerting the rest of the team as the blond haired supergirl greeted Nightwing, yelling out "boss" out of habit just as she slammed Tim down to the floor, long forgotten. Nightwing slightly winced in pain for the poor boy, quickly turning his attention to the teen as she all but flew towards him to greet the hero. "It's been forever since you last visited!"

Voices of agreement sounded through the air as the team began to make their way up to their former leader, all greeting him. Conner was one of the first, walking up to him with M'gann behind as he stuck out a hand to his friend. "It's been a while." The half kryptonian greeted, smiling at the relief of seeing the dark haired boy.

"Yeah," Nightwing said, "I've been busy but I'm back now." The hero said, letting go of his hand to greet the green Martin behind him with a hug.

"We've missed you." M'gann murmured fondly and Jaime who was the nearest next to her agreed.

"She's right amigo." He said shaking his head. "We started to think you had left the team."

"You know I would never abandon the team." Nightwing said, sounding distinctively upset. His eyes scanned the small crowd before him, taking notice of Bart in his Kid Flash costume as he made his way over to the group in an instant and grinned. "I told you he wouldn't. Nightwing would never do that." The time traveler stated offhandedly, nudging the tanned teen as Garfield laughed at the exchange.

The green skinned male smiled at Bart in amusement. "You're only saying that cause you knew he wouldn't."

"Eh what can I say?" The speedster shrugged, smirking almost smugly in an oh so Wally fashion. "Future perks, which I have to admit is so crash."

Robin looked at the trio. "That doesn't matter anymore." He said, standing beside his brother with a small smile and his arms crossed. Barbara was by his side. "At the very least he's back and the teams back together."

Nods of approval went throughout the group and for a moment Dick wanted to say that they were wrong, that there was still somebody missing but kept his mouth shut. Through the small crowd, his eyes met with Artemis's solemn ones as she stood near Karen and he could guess that she was thinking the same. Around him, he greeted the rest of the team, congratulating Static once again as a new member of the team and making his way through each member one by one.

It was only when he had believed that he had gotten through all of them that he found himself surprisingly wrong, staring at the face of his old friend Arsenal. He hadn't noticed the ginger earlier and guessed he had been off somewhere by himself as he stuck out a hand with a smile. "I didn't know you'd be here." He hadn't indeed. The last he had seen of his old friend was when he had kicked him off the team, only to see him back here with the others. Just what else had he missed while he was gone? Not that he minded having him back- if anything he was happy. He saw more of the other Roy than this one, having visited the baby often and catching up with him- like he had done before with this one before he had disappeared eight years ago. "I'm glad to see you."

Arsenal nodded, grabbing hold of the outstretched hand with his own- his good one- and smiling slightly. "I didn't expect you to be coming either though I suppose it's good to see an old face." This seemed unlikely. They had not been on the best of terms the last time they had seen one another. "I guess this mission is more important than I thought for you to be called in earlier from your break."

"I suppose so." Dick muttered, shooting Barbara who was near him a look that asked for explanation. Turning away from Arsenal as he made his way back to his spot from before, Nightwing looked to Batgirl in question. "What's he doing here?"

"I'm not exactly sure in all honesty." Barbara said, sighing as she glanced at the said person. They were further away from the others now, towards the entrance where she continued to play on the hologram. "He was called into the mission today without anyone knowing saying he would be needed- whatever that means."

"Who called him in?"

"I did."

At the sudden sound of the new voice throughout the room, the team began to quiet down at the appearance of Batman entering with Kaldur on his heels. The faint sound of the television sounded in the background and in an instant M'gann had shut it off with her telekinesis, beating Mal to it as he had just begun to grab the remote. The team of teens looked expectantly at the Dark Knight.

"I'm glad to see you're all here." The gruff voice started, and Nightwing imagined that if he could see his eyes, they would be trained on him as he said the statement. "The upcoming mission will be one that will require all of you to participate in some way to assure its success, one being Arsenal as he will be joining you all."

At the mention of such, a few eyes turned to the ginger in question who was sitting towards the back of the room, and further away from the others as they all began to huddle around the dark knight to hear the mission. Nightwing made his way towards the front of the group, looking towards his mentor and watching as the hologram Barbara had once been fiddling with was pulled towards him and Kaldur. Coordinates of a seemingly isolated jungle appeared before them and Nightwing took note that it was located in the country of Bialya, making eye contact with Tim who also noticed such.

Kaldur stepped forward. "Tonight's mission will be a covert operation, intent on kidnapping an important assassin of the Light." Bringing a dark arm up, the Atlantian swiped at the screen, a hologram of a girl of average height appearing. The girl stood staring forward, along with smaller photos surrounding her, all in action, a dark body suit hugging her slim yet curvaceous body and a dark hood covering her hair. A black mask finished the outfit, hiding the bottom half of her face as sharp eyes looked forward, thick eyelashes surrounding them. Aqualad turned his attention back to the team. "She goes by the name of Belladonna, a well known assassin wanted in over 83 countries and wanted for her hacking, stealing of information, and occasional assassination of influential politicians around the world."

"Sounds like she'll be fun to deal with." Mal muttered, arms crossed over his chest as Barbara agreed. "What's our objective for kidnapping her?"

"Information." Batman answered, narrowing his eyes behind the mask. "She's a well trusted agent for the Light and will know more than any other agent we could possibly get our hands on."

"And how do we know we can trust her?" Karen questioned, hands on her hips as she stood near her boyfriend. "I mean if she's as loyal as the others, how do we know she'll tell us the truth or even tell us anything?"

Nightwing already questioned the same point to himself. When Batman had first approached him about the mission, he hadn't told him much except that it was involving a covert kidnapping- something that the Justice League was never one for. Kidnapping for something that didn't exist in the League's vocabulary and Nightwing knew there was more to it, especially as Kaldur and Batman exchanged glances. He admitted to hating being out of the loop, but he only had himself to blame for having been gone so long.

Kaldur glanced at the team, eyes searching as they landed on Nightwing before turning back to the hologram. "You make a valid point that would be acceptable if Belladonna was truly who she seems she is." He paused at this, turning his attention back to the group. "However, this mission nor Belladonna is what it seems on the outside. In truth, Belladonna is a double agent that has been infiltrating the Light to gain Intel and keep a close eye on them for the League."

"A double agent?" Artemis questioned, and at the mention of such, a slight tension fell over the team. The last double agent had been Kaldur, and a secret hidden from the team by Nightwing, Aqualad, and Wally, causing the faked death of Artemis and a small amount of distrust to circle the team for a short period of time. No one seemed happy at the mention of such.

"Neptune's beard!" Lagann exclaimed, clenching his fist. "Another double agent? Haven't we had enough of that- of the lying? Why weren't we told about her before?"

"You are wrong Lagann." Kaldur said. "Belladonna's mission had been assigned to her a year before the start of the team. I had not even known of her existence until most recently as it was the League's decision to keep it hidden for her safety in case anyone found out of her identity- something they could not risk."

"He's right." Continue Batman, stepping forward so that he had their attention. "For years she has been keeping an eye on them and has helped on more than one occasion in the information she manages to give us when she could and their latest plans. However now with the sudden turmoil within the organization due to Savage's disappearance, it's too dangerous to allow her to stay. Which is why this mission is not a kidnapping but rather a rescue made to look in such a way that the Light will not question anything."

At the mention of such, the team stayed silent for a moment, Nightwing feeling his mind wrap around the objective. Beside him he could feel Barbara shifting, opening up her dark red lips. "Who is she?" She asked.

For a moment, Nightwing saw Kaldur hesitate, his light eyes flickering slightly over him once again and then to Arsenal and Barbara. The dark haired hero frowned. "At the moment the League has decided to withhold that information until you have recovered her. For now she will be simply known as Belladonna." He informed them, continuing before anyone else said anything. "Blue Beetle, Arsenal, Kid Flash, you will be Alpha with Nightwing leading you."

Nightwing and the other three nodded glancing at one another and smiling slightly besides Bart. Watching as the usual up beat teen stood still, Dick took notice of the slight downturn of his lips and the stiffness of his body. Raising an eyebrow, he turned his attention from the younger male to the remaining member of his team. Arsenal had remained towards the back of the room, having not shown he took notice of the information. But Dick knew him, and could tell he was paying as close attention just as everybody else. He smirked.

"Team Beta will consist of Miss Martian, Superboy, Tigress, and I." The Atlantian continued. "Gamma squad, you will be consisting of Guardian, Static, Beast Boy, Lagann, and Robin." Aqualad turned to the remaining members. "Batgirl, Wonder Girl, and Bumblebee you will be team Omega."

"Team Gamma again? Barnacles!" Lagann muttered, crossing his arms angrily.

"No need to get upset Lagann. Your part in your team will be just as important as the others in getting Belladonna out safely." Batman said, changing the hologram back again to the coordinates of the jungle from once before. "Alpha and Beta squad, you will be infiltrating an isolated jungle in the country of Bialya, under the reign of Queen Bee, a prominent member of the Light as all of you know. There we have been informed that there will be a shipment of nuclear missiles that will be used in nuclear war that Queen Bee plans on using against her neighbor country Qurxan due to their broken alliance. There you will disarm the shipment without causing any further damage or causing one of the warheads to go off. Through all the commotion will be when we put into plan the rescue of Belladonna."

"Team Gamma, you will be here, back at the base to keep track of the mission and give help when necessary or arrive as reinforcement if needed." He continued, then turning his head to the last three remaining girls. "Team Omega, you three along with Zatanna, and Rocket will be attending a Gala in the same country, hosted by Queen Bee herself during the same night of the mission. There you will be in disguise and will keep an eye on Queen Bee and distract the party when given the signal so that she will not be able to get to the location when the news reaches her. Is that clear?"

Nods of understanding and agreement sounded from the team, and Batman nodded, glancing back at Aqualad as they exchanged a silent look. Nightwing looked at the two of them. "And what about Belladonna? How are we supposed to get her through all the commotion without it seeming suspicious?"

"I'm glad you ask that Nightwing as this is where you will be needed." Aqualad said, turning his attention to dark haired eighteen year old. "In order to make this believable to the Light, we will need to fake her death. And to make it seem as realistic as possible, you will be the one to make the blow- quite literally. Due to the Light's knowledge of our plan from two months ago and Artemis's faked death, I cannot be the one to carry out the objective as it will make it suspicious if the Light is informed I was the one to take the final strike on her. Instead, you must actually be willing to injure her in order to get her to the spacecraft."

His fingers dragged across the screen of the hologram, zooming in till a clear image of the jungle was visible, a distinct cliff shown in the image. Kaldur pointed at the ledge. "You will pursue Belladonna in combat and in between she will allow you openings to strike a seemingly deadly blow. From then on you are to push her off the cliff, weather it seem accidental or purposeful to those around you, where miss Martian will be waiting in the Bio-ship to catch her fall."

"But that means-" Cassie began, looking from Kaldur to Nightwing slightly wide eyed.

"-I'll have to actually strike her to make it as realistic as possible." Nightwing finished, narrowing his eyes at his mentor and friend. "That's a risky gamble you're playing there. If things go bad, there's a possibility that I can inflict a life threatening wound to her if my aim is off or I get distracted."

"Which is why we have chosen you." Batman said. "You're the best at aim and we trust that you'll be able to strike at her without causing too much injury. And even if so, we have to take the ris-"

"But isn't there anything else we can do?"

Turning their attention to the one who voiced the question, Bart stood in front of the group, having made his way forward. There was a sudden look in his green eyes, one that looked something to paranoia, fear more likely in Nightwing's opinion. Hands clenched, and his mouth set straight, Bart looked at the two leaders, looking every bit defiant at the plan. Kaldur looked slightly started at the outburst, looking at the male questioningly. "What do you propose Kid Flash?"

"Anything- just anything but that. She-" He paused suddenly, bowing his head as if in shame. "In the future-"

"Bart." At the sound of his name, the speedster looked up begrudging to Batman, and Nightwing finally understood what had been bothering the teen ever since the mission had been mentioned. "Is this life threatening to the future? As in something you came back here in specific to change?"

Opening his mouth and shutting it closed, the face he was making would have been comical had it been in any other situation. But Nightwing could see the desperation in his eyes, and could tell it was a personal ambition of his to change whatever happened in the future concerning the mystery girl.

Watching as he set his mouth rigidly, Bart shook his head. "No, but-"

"But nothing, Bart." Batman said, making it all the more important by using the time travelers actual name. "You know the consequences of tampering with the future and while you helped save it from the world going to crumbles- that was your only objective. Unless this is something that will have a large reaction, then we can't risk changing it in case of unnecessary consequences."

Stopping, Batman turned to Kaldur, nodding his head and addressing the rest of the team while Bart kept his head down, looking every bit ashamed and upset. "Your mission will be in five hours. Be ready by then and Aqualad will brief you in on the details later."

With that, the Dark Knight had turned, making his way towards the entrance and leaving behind a silent team who all had different reactions. Nightwing had stepped away from the group, watching as they had dispatched and gone respectively to their rooms to get ready for the mission. Kaldur and Dick were the only ones left by then, and his blue eyes lingered on a certain speedster's back as he made his way out the room last. He turned to Kaldur. "You think it's for the best?"

"Kid Flash's reasons for wanting to change this mission are purely his own. Whatever happens in the future cannot be changed if it does not endanger anyone's life, especially Belladonna's." The Atlantian turned to Nightwing. "However for both the sake of the future and Belladonna, be precise with your aim my friend. It may very change the fate of this girl forever."

A/N: I'm not crazy about the chapter in all honesty but it's a start. In my opnion it feels forced and rather boring along with really rushed. However I'm trying to get to the better parts more faster and I can assure you that the next chapter things will begin to make more sense and begin to follow an actual story line.

Either way please comment and favorite if you did happen to enjoy it :) thank you!
