This is a remake of my Young Justice/ The Vampire Diaries crossover. A new OC and, hopefully better written. Please enjoy and leave your comments. This story most likely will be dark, so fair warning. Disclaimer: I own nothing.

An Unknown Location

A barely conscious young girl is sitting in a cell. She has matted blonde hair, blue eyes, and a pale complexion. She is currently laying down, being too weak to sit up or even stand. She opens her heavy eyes and looks around the gray dull cell, with its heavy iron reinforced door. It has no windows where sunlight can enter. The girl then looked down at her ring finger, still not seeing the ring she wore for the past century. "They all will pay dearly," the girl muttered darkly, then she just laid there on her stomach, too weak to do anything.

(Meanwhile Mount Justice)

"Team report for mission briefing", a deep voice announced over the message system. Five teenagers came running into the briefing room, two girls and three guys. All five of them looked at each other then towards the man who called them. "OK here's the situation," the man began, bringing up pictures of an old building with what looked like guards and medical staff outside it. "This picture was taken eighteen hours ago, near Gotham, we tried sending leaguers to investigate, but they have been rebuffed," He explained. "I want you five to investigate." He finishes turning to the teens. After a minute the youngest teen, Robin, speaks up, "Do you have any idea what they are up to, Batman?" He asked his mentor. Batman shakes his head, "I don't have a solid idea, but they may be doing medical research. Whatever the case, I want you five to investigate and get all the intel you can." Batman responds. Aqualad replies, confidently, for the team, "We'll get it done." Batman nods, "I'll leave you to plan." He then walks to the zeta-tube and leaves the Cave. Aqualad turns to the team and says, " Let's get going. We can plan on the way." Everyone nods and heads to the Bio-ship.

(AN: I DON'T KNOW HOW LONG IT WOULD TAKE TO GET FROM HAPPY HARBOR TO GOTHAM. SO I'M JUST GOING TO SAY TWO HOURS HAVE PASSED.)

Unknown building near Gotham Unknown Girl POV (this part may be dark so fair warning)

I didn't know how long I was asleep, but an alarm woke me. I do my best to get into a sitting position, my blood deprived body protesting my every movement. After struggling to sit up, I move towards the back of the cell, feeling like my veins are rubbing together. I look towards the door, just as a guard enters my cell. He gives me a murderous glare. "Look at you, nothing but a waste of space," he says to me. I see a wooden stake in his hand. As he comes closer he raises the stake to deliver a killing blow. I slowly reach into the crevice behind me, and grab the rock I've stashed there. As the guard gets closer and bends down, I wack him in the head. He falls onto the ground, with a grunt of pain. I start to try and get up when I smell it, the sweet metallic smell of blood. I look towards the guard, like a tiger looking at prey, "I'm hungry", I say to him. He gets a look of pure fear as I show my vampire face, red eyes, fangs, and black veins under my eyes, I then pounce on him growling and snarling. I bite his neck and have my first real meal in sixty years. I continue until he goes limp, I then wipe the blood from my mouth, grab the stake and rush out intending on killing the staff. While I'm looking for my daylight ring I run into a few guards. They do a double take and draw their guns. I vamp sped towards one, I punch him in the throat and throw him on the ground, I then sprint to the second guard and punch him in the cheek. I punched him so hard I heard his neck snap. I continued on until I found a storage room. I start to rummage through the boxes looking for my daylight ring. After a minute of searching I've finally found it, an old gothic looking ring with a lazuli gem. "Got it now to find a way out." I say out loud, then I speed down a hallway killing any guards I come across.

(The Team, around the same time, Aqualad's POV)

The plan fell apart, we were supposed to sneak in, but the staff must have seen us on a camera, because a few minutes after we entered the alarms went off. Robin went off, like he usually does, I'm guessing to find the intel, while me, Superboy, Miss Martian, Kid Flash, and Artemis fight through the guards looking for any other intel. All of a sudden, Superboy knocks a guard out and turns toward another hallway, "I hear some more coming", he warns us. As we get ready for a new fight, we start to hear screaming and growling. "Is that a wild animal?" Miss Martian asks, terrified. "I don't know, but we should check it out. Superboy lead the way." I command. He nods, and starts to lead us down the hall towards the fight, which sounds like it's dying down. Once we turned the corner, ready for a fight, we were horrified by the scene. Dead guards and medical staff all over the floor, with bite marks on some of them. "What the heck happened here?" Kid Flash asked, looking a little green. "Oh, I think I'm going to be sick." Artemis said, dry heaving. Miss Martian, Superboy and I were in a disgusted shock. While we were considering what to do next we heard a desperate male voice, "No, please." Before we figured out where the voice was coming from, a male doctor was thrown into the wall five feet in front of us. He hit the wall and slid down it, with a look of pure fear on his face. "Get ready everyone." I whisper command and they all nodded. As we get ready to help the man, he screams, we look up and see a small looking girl biting on his neck, growling and snarling. We are in stunned silence until Kid Flash breaks it. "Is this a zombie lab?" He asks, looking even more sick than before. After Kid Flash made our presence known, we turned back to where the girl was, who was starting to get up. When she is fully standing she turns towards us, showing off her terrifying face. She looks at us and hisses, then bolts off. "Umm what just happened?" Superboy asks aloud. "I think we're all wondering the same thing, SB." Kid Flash answered. "Come on, let's find Robin, so we can get out of here." I said, everyone nodded and we start to look for our ninja teammate, while looking out for a murderous girl. "Miss Martian, can you give Robin a heads up about Murder Girl?" Artemis asks. I see Miss Martian concentrate for a minute then she says, "I can't reach him, he's out of range." "Then we have to hurry, KF go on ahead and search the rooms and be careful." I command. KF nods and darts. We continue to check the rooms.

Murder Girl POV

'OK, let's see here'. I think as I look at the map I stole. 'Turn left then right ok got it'. I put the map away and dart towards the exit. As I slow to a walking pace, I get the feeling I'm being watched. I stop and focus my hearing. Soon I hear the soft patter of footsteps. 'Mm a trained tracker. Well let's see how good you really are.' I think, then I vamp sped towards the exit. I hear the soft footsteps speed up trying to keep up with me, I smirk, stop and listen. Soon I hear it, the ting of metal flying through the air from behind me. I turn around and slap the metal to the ground, realizing that it's a bird shaped boomerang. "I know you're there, come out," I say in a monotonous voice. I bend down, still focusing my hearing, and pick up the boomerang, "I'm not looking for a fight, but apparently you are though." I, once again, say in a monotonous voice. I hear a gasp from the ventilation shaft, and I smirk, "gotcha," I mutter. I throw the bird boomerang at the ventilation shaft with all my strength. Soon I hear that metal on metal protest as the boomerang slices the shaft and gets lodged in it. I vamp speed to the shaft and rip it open. Soon a small boy, wearing some kind of costume with a domino mask, falls out. "That was incredibly stupid thing to do," I tell him in the same monotonous tone. He tries to punch me but I just grab his fist and I just squeeze it. Soon I see a look of fear and pain on his face. I kept squeezing until I heard his bones break and he screams in pain and I soon hear multiple footsteps coming this way. I look down at the boy and I let my real face show, "Some people are coming, so we will finish this later and hopefully next time we will be able to finish what we started or, if you're lucky to meet me when I have my humanity back on, we'll be civil, but I doubt it. Anyway, here are some things to remind you to not attack someone from behind," I tell him threatenly. I proceed to punch and kick him in the stomach and face, then I vamp speed out the exit.

The Team(Aqualad's POV)

We continue to make our way through the halls looking for Robin. After a few minutes of searching we decided to head back towards the exit and see if Robin went back to the ship. "Wait, do you guys hear that?" Superboy asks us. We stop and listen. "I don't hear anything my friend, what does it sound like?" I asked him which way. "Towards the exit," Superboy replied. I nod, "Let's move it." I command, and we all start running. Kid Flash got to the area before us "Guys, Robin is injured." Kid Flash yells at us. We hurry our pace to get to Robin. When we got there, I'm shocked at his condition. He got cuts and bruises on his face and, most likely, his chest, a black eye and he'sunconscious. "Artemis, when we get back to the Bio-ship, do what you can to stabilize him. Miss Martian, levitate him so we don't make his injuries worse. Everyone else keep an eye out." I give out my commands and we get to work, and soon we get Robin on the Bio-ship and Artemis gets to work applying first aid. "Red Tornado, come in, get MedBay ready, and tell Batman that Robin is injured." I say into the comlink and I can see everyone pale once I mentioned Batman and they all look at me with fear. "What, he was going to find out eventually." I reason. "Then you can tell him what happened." Kid Flash pops back, still pale. We all ride back to the cave in an uncomfortable silence.

AN: first chapter done. I hope it's better written. The vampire's name is Jess, and her humanity is turned off that is why she's so violent. I'm planning on her starting as a villain, then her turning on her humanity and being an anti hero. Something like Damon was in The Vampire Diaries. But anyway please review and follow, thanks for reading.
