AN: This is a Bioshock 2 x Young Justice crossover. The timeline for Bio shock has been adjusted so that it will coincide with the events of Young Justice. This is post-Bioshock 2 with Delta as a Savior and where Eleanor doesn't kill Sofia Lamb. It will be set between the team's face-off with Amazo and Artemis joining the team so Eleanor will join the team at the same time as Artemis (between episode five and six of season one).

For those who haven't played Bioshock 2, Eleanor's powers are telekinesis, pyrokinesis, teleportation, and superhuman strength, agility, and regeneration, compound intellect, Little Sister Possession (she can't use it on regular people yet), and Extrasensory Perception (a sixth sense for danger like Spider-man's Spider Senses). She may get more plasmids later on because Delta had more plasmids than her before she absorbed his ADAM.

Delta will act as her conscience and give her advice during battle. He might give her a slight protection against mental attacks so Psimon will have some difficulty in mentally subduing her for he will have to get through Delta first.

Chapter 1

It has already been two days since Eleanor escaped Rapture with the former Little Sisters and her mother, Sofia Lamb in tow. Fortunately, they should still have enough rations, water, and fuel to get them to dry land. Eleanor, with her knowledge of survival, equally divided the supplies amongst themselves.

For Eleanor, the previous events felt like they occurred so long ago that she couldn't believe it happen.

She first remembered her father, Delta and her running to reach the lifeboat before the explosion went off. Secondly, the temptation to just let her mother drown instead of saving her. Finally, her father's last moments before she took him into her compound intellect so he can live on and guide her in her mind.

That last memory still pained her despite Delta's presence within her because she still saw him die again right before her very eyes. Unlike last time though, she was able to do something to help.

But now is not the time to mourn for him. There will be plenty of that after she returns the little ones to their families. It's what Father would have wanted.

Sofia remained idle ever since they left Rapture. She would only react when Eleanor gives her food and water but that was the only interaction she would get because the little girls didn't want to approach her and her daughter was still tempted to kill her.

Even though she saved Sofia's life, Eleanor would not hesitate to kill her if she attempted to harm them. She could hear Father agreeing to this. So for her mother's sake, she better not try anything.

The only problem left was what she would next once she returns the girls to their respective families. She should probably look for Jack Ryan to help her adjust to this new world. If there's anyone that could help her adjust to a life outside of the hell that is Rapture it's him. That is if he is still alive.

It would be extremely difficult to track him down though even with all the memories her mother gave her about the surface world. The only information she had was on the time that Jack was in Rapture. Like when he first arrived in the underwater "utopia", the rescue of the Little Sisters, and him killing Andrew Ryan and Frank Fontaine. What he did after his departure was anyone's guess now.

But will she be able to leave everything from Rapture behind. The experiments done unto her by Sofia Lamb and Gil Alexander left her changed beyond that of regular human. It left her more powerful than even her own Big Daddy. She also can still feel the ADAM in her body giving her more plasmids than she originally had. She doesn't have a sure control over them though so she should stick with the ones she already knows.

She was going to need more than Jack and Delta's help to control them so she won't accidently bring harm to the people around her. She required to find a way to contain them or shut them off.

"I'm not entirely sure if I can give up using my plasmids now. There might not be a need for it but I'm not as naïve enough to think that there's no people as bad as Andrew Ryan or my mother. My mother originally made me into this to bring about her idea of utopia to the world, but I want to use these powers to protect like what Father did for me and the rest of the Little Sisters." She pondered as she stared at the fire she made with her plasmid to protect them from cold.

She wasn't sure on which this desire to protect belongs to: hers or her father, but a moment of realization told her that this desire belongs to both of them. The corrupted dream of Rapture may be over but there will still be people that will try to seize control of the world.

She vaguely recalled that there was a group of super-powered individuals known as the Justice League. This knowledge was given to her by her mother's experiments so she could defeat them when they face each other. She only had knowledge on a few of the members since her the experiments were abruptly ended because of her father. Maybe she could join them or at least help them.

She also remembered that there were people who abused their powers and used them for personal gains. It would be similar and yet different compared to fighting splicers.

"With my powers and Father's guidance, they will never see me coming." Thought Eleanor as she clench her fists and gazed at the horizon in heroic determination that made Delta proud of her conviction.

The Team was soaring over the Atlantic in the Bioship. The red organic ship cut across the waves as if they were nothing. It was also cloaked to prevent any watchful eyes from seeing this alien vessel with its motley crew.

Its motley crew consisted of Miss Martian, Aqualad, Superboy, Kid Flash and Robin. These young heroes were currently on a mission assigned to them by none other than Batman.

The mission was to investigate a massive underwater explosion in the middle of the Atlantic Ocean. They were to find the source and discover how could something like that remain undetected. What made it even more alarming was that it was close enough to the underwater city ruled by Aquaman to feel the shockwaves from the explosion but far enough to be unable to quickly swim to the source.

The Justice Leagues' protégés can't help but reflect on the mission briefing earlier.

Flashback Start

Back at Mount Justice, the Team was doing their daily training. They were working on their teamwork at the moment. It would've made more progress if it weren't for Kid Flash flirting with Miss Martian at every chance he got despite it being clear that she wasn't interested in him like that.

The training (and the young speedster's flirting) was abruptly interrupted as the zeta tube announced the arrival of Batman, Robin's mentor.

The presence of the Dark Knight here can only mean one thing for the young heroes. They have another assignment.

They were wondering on how urgent this was because they have just recently faced Professor Ivo, his simian androids, and Amazo. Superboy could still feel the blows of the robot mimicking Superman's super strength. He groaned at the memory of that while Kid Flash groaned at the fact that they barely had a few days rest from their last mission.

"Hey Batman, got a new assignment for us?" the Boy Wonder playfully asked the caped crusader which got him a glance of acknowledgement from Batman.

"As a matter of fact, I do have another assignment for the team," the Dark Knight stated in his usual gruff voice.

A holographic image of the world map immediately appeared behind him. "The Justice League's scanner picked up a large underwater explosion that occurred in the middle of the Atlantic Ocean," he informed them as it zoomed towards a certain spot on the Atlantic.

Upon hearing this, Aqualad's heart sunk. He feared that something terrible had happened to his home. Robin, Miss Martian, and Kid Flash also worried for their friend's home. Superboy was now ready to punch something because of Kaldur's predicament.

"The explosion was far enough to cause no damage to Atlantis or this would otherwise be a League priority and I would not be briefing you on this," Batman reassured Aqualad, sensing his fears.

The speedster, who was eating an energy bar, couldn't help but interrupt by asking him a question that the rest of them wanted to ask.

"Why can't ya have Aquaman and Kaldur to check it out 'cause not all of us are good underwater?" he asked with his mouth full.

"Aquaman is preoccupied in calming down the marine life which was somehow affected by the blast and caused a massive panic." The Gotham Defender answered.

"So that is why it is up to us to investigate it." Aqualad concluded, earning a nod from Batman.

"A small vessel was also discovered coming from the explosion." The Dark Knight pointed at a smaller point that was moving slowly and came from the previous point.

"So whoever is in that boat is responsible for this," said Superboy with arms crossed and face scowled.

"So what are we waiting for? Let's go kick their buts and maybe get a souvenir while we're at it!" Kid Flash bumped his fist to his palm. He was as energetic as usual and Robin chuckled at his best friend's display.

"Still trying to be impressive to M'gann, huh?" mused the Boy Wonder with a smirk.

"You already know what to do," Batman stated as the holograph shut off, "and I expect a full report when you return from your mission."

Flashback End

Superboy continued to stare out the window of the Bioship as they got nearer and nearer to the boat. He was getting impatient and wanted to get this over with already. But he tried to reel in his temper when he remembered Black Canary's training.

He thought back to the fight with the android, Amazo, and how getting angry almost got him and his teammates killed so he devoted himself to have better control over it. This would've been easy if it wasn't for a certain speedster.

"Are we there yet?" Kid Flash asked for twenty-seventh time.

The Kryptonian didn't really hate the speedster but he really can get on a lot of people's nerves including Superboy's. It doesn't help that he's always flirting with M'gann.

"Him flirting her always makes angry for some reason. I wonder why." Superboy thought to himself.

His feelings for the young Martian were confusing at best since he wasn't very good with emotions. The closest word he could find for it was something he would never admit to anyone: infatuation.

"Are you alright, Superboy?" Miss Martian asked him with a tinge of concern in her voice. This interrupted him in sorting out his thoughts and feelings.

"I'm fine," the Kryptonian replied as best as he could which came out with him sounding grumpy.

"Ok. Just hang in there," the female Martian replied, her usual sunny expression on her face.

As Superboy was wondering when would they reach their destination, the Bioship's scanners picked something up which was the boat they were supposed to find.

"We have found the vessel," the Atlantean stated to the team "Be ready for anything."

With that said the young heroes prepared themselves for a fight that would surely come, considering how their luck was so far. But nothing could prepare them for what came next.

AN: And done. There that was my first fanfiction so I hoped I did a good job with the writing and that the characters weren't OOC. I'm also a complete amateur in writing a story so it might seem a bit forced or transitioning too fast. Please review on what you think and if I should continue this or not. Thanks for reading.
