Author's note: I've been writing for about a year now, and discovered this site a month ago. Reading everything gave me the urge to write a fanfic to stimulate my creativity, plus it sounds fun.

I am a huge fan of both SVU and The Dark Knight Trilogy, and late at night while reading fanfiction, I came up with a perfect way to integrate the two into a crossover. I'll follow the plot of the Trilogy, but with some interesting changes. This is the first part of the trilogy, and I do plan to see it to the finish.

Disclaimer: Unfortunately, I do not own either SVU or The Dark Knight Trilogy. They belong to Dick Wolf and Christopher Nolan respectively. Now what I would do if I did own them… ; )

I know the chapters are long but that's my style. If you wish, in the next chapter I will publish which characters are substituted for who if anyone is confused, but for now enjoy my first Fanfic! Please Review!

Law & Order: Batman and Batgirl Begin

Chapter one: origins

Dr. Thomas Wayne, MD, FACS was sitting at his desk, leaning back glossing over medical charts. While he had taken the weekend off to spend time with his beloved wife Martha, there was no rest for the star surgeon and the latest patriarch of the Wayne Family, one of Gotham's most prominent families.

Finishing with the medical files, he picked up another from a different pile on his desk, one that was stenciled with the signature logo of Wayne Enterprises. Although he loved his job at the hospital, Thomas Wayne felt an obligation to his family's company, and thusly served as its chairman. The file contained a memo regarding the possible poaching of a bright engineer from Lockheed, a one Lucius Fox. Glancing over the man's qualifications, Wayne liked what he saw and made a note to hire this man.

A slight knock on the door jarred him out of his work. "Come in." In strode Martha, his wife. His lips curled back in a soft smile. After years of saving lives, now Martha and I have created one. Martha was six months along and simply radiant. All over Wayne Manor, all the staff was exited for their employers, especially Alfred, the butler.

"Hi dear," said Martha. "Can we talk to you?"

"We?" asked Thomas. Martha turned to the door and motioned for someone to come in.

In strode Karen Cabot, his housekeeper, who was five months pregnant with a girl, a potential playmate for his son. "Karen has a favor to ask of you."

"Karen, of course you can ask me."

Karen smiled weakly. "Master Wayne, you know my half-sister Serena?"

Wayne raised an eyebrow, not knowing where she was going with this. "Serena, yes I saw her at the last Christmas party. I thought she was your full sister."

She shook her head. "No, after my father died, my mother married Lucas Benson, Serena's father. She's four years younger than me."

"Ok, so what about her?" he said in a friendly manner.

"To his horror, Karen's eyes teared up. "Seven months ago, she was brutally raped in her campus, and now she's pregnant with his baby."

Thomas' mouth dropped. "Oh my God! How horrible!"

Karen fought back a sob, "She's despondent; cries herself to sleep every night. I don't know what to do."

Martha put a hand on Karen's shoulder. "Tom, I told her that Serena could move into a spare bedroom in Wayne Manor. She needs her family close by. Is that alright with you?" She looked at him as if saying "It better be alright with you!"

Thomas rose and gave his employee a hug, letting her cry into his shirt. "Of course dear. She can come and stay as long as she likes." As Karen was mumbling thank yous into his shirt, Thomas looked at his wife's belly. I guess my son will have two playmates.

Eight years later

"Liv. Come out come out wherever you are." Olivia crouched behind a rosebush, trying to blend in to the foliage. Looking on the terrace, she saw her target, who was too busy looking in the other direction.

She gave a predatory grin and charged. "Gotcha!" Her target turned quickly just as she tackled him to the ground, pinning his arms on the tiles. "I win again Bruce," she smirked.

Bruce Wayne, her best friend, squirmed under her. "One day Liv, I swear I'll beat you!"

Chuckling, Olivia rose and helped Bruce up. "I'd like to see you try." He stuck his tongue out at her.

"Hey guys, come here!" Both of them turned and ran to the greenhouse. There, hiding underneath a table, was Alex Cabot, Olivia's other best friend. "Look what I found." She opened the palm of her hand to reveal an Indian arrowhead. "Finder's Keeper's."

"Yeh, but it's my garden so…" Bruce looked at Alex's hand for a moment before… "Finder's Keeper's." Laughing, he snatched the arrowhead and ran off.

"Bruce, give it back!" Olivia yelled, running after him. He had a head start, so when she, Alex in tow, exited the greenhouse, he was nowhere to be found. Seeing a slight movement from an old well, she smiled mischievously. "Ah ha!"

To her horror, the old boards gave way and Bruce fell down the well. "Bruce!" screamed Olivia and Alex in unison. Both peered down the well, and when seeing he was still alive Olivia told Alex to get help. "Don't worry Bruce, we'll get Uncle Alfred. Stay calm." She turned and ran toward Wayne Manor.

Bruce started shaking, the performance reminding him of the terrifying hour spent in the well before his father and Olivia returned to save him. His father, sensing his son's fear, escorted him and his mother out of the Opera house, heading for a side exit. "Is something the matter Tom," asked his mother, worried about her son.

"No dear, it was me. I just needed some fresh air. A little bit of opera goes a long way," he replied, winking at his son. Bruce couldn't help but smile; between his mother's love and father's kindness, he knew that as long as they were with him, he was going to be alright.

Just as they were about to enter the main street, a disheveled man with long, scraggly hair pointed a revolver at them. "Wallets, jewelry. Now!" he demanded.

Bruce was scared, clinging to his mother. His father though was surprisingly calm. "Alright," he said, handing the wallet over to the guy. "No problem." The man, who had the reek of booze all over his body, fumbled, dropping the wallet. Picking it up, he pointed the gun at his mother. "Jewelry too!" As his father stepped forward to protect his mother, the guy fired point blank, running away. Bruce, scared to his very core, surveyed the scene. His mother was lifeless on the clammy pavement, blood seeping underneath her.

"Bruce." He turned to see his father smiling weakly at him. "Don't be afraid," he croaked before his eyes closed in the everlasting sleep of death.

Three hours later, the still shocked Bruce Wayne sat in a chair in the local police precinct. All around him, the press were having a field day, for a billionaire socialite gunned down with his wife was front page news. "Hey there little guy." Bruce looked up to see a young police officer on his kneeling in front of him. The man oozed toughness, but possessed a comforting smile. "This your father's?" He wrapped the coat around his still shaking shoulders, comforting him as best he could. "It's ok; everything's going to be ok."

"Stabler!" Bruce saw another cop in full uniform enter. The young officer patted Bruce once more on the cheek and walked out. The new guy, owning bony face with dark, thick glasses, smiled down at Bruce. "Hey. My name's Captain John Munch. I just want to let you know, we got the guy. His name's Eddie Skinner, a real lowlife." Bruce didn't know what to feel, because even if the man was caught, his parents were still dead.

The funeral for Thomas and Martha Wayne had just ended, and Alfred led Bruce into Wayne Manor, a protective hand around his shoulder. "I thought I might prepare a little supper."

"Alfred," said Bruce, tears in his eyes. "It's my fault their dead. If I hadn't gotten scared…"

"No Master Bruce," said Alfred, hugging the boy. "This was not your fault. It was nothing that you did; it was him and him alone."

"I miss them so much," Alfred could feel his ward's sobs through his suit.

"I miss them too Master Bruce." He looked down at him. "Hey, I've got something that'll help." He led the boy out of the room and into the main foyer.

"Bruce!" Running forward, two young girls, one blonde and the other brunette, hugged him at the same time. "I'm so sorry," said Alex Cabot, pulling him close. Alfred smiled, for he knew that the two had a crush on each other.

"This isn't your fault," cried Olivia Benson, her arms around his neck. "You shouldn't feel guilty." Looking down at the brown haired mite, Alfred couldn't help but shed a tear, for he considered Olivia to be the daughter he never had.

"Alex, come now, we have to go," called Karen Cabot, the now ex-housekeeper. With their services no longer needed, they were leaving to find new opportunities elsewhere.

"Bye Bruce. I'll be sure to keep in touch." Alex kissed her friend on the cheek and walked toward her mother.

"Olivia!" A blood curdling scream echoed through the Manor. In strode Serena Benson, a half empty bottle of scotch in her left hand. "Hurry up!" Alfred stared at her, anger in his eyes. She was like this all the time, drunk and abusive towards her daughter. For the last eight years, Alfred and Master Thomas had spared little Olivia from the worst of it, but now there was nothing they could do.

Crying herself, Olivia gave Bruce one last hug. "Remember Bruce, friends forever." She let him go and turned to hug Alfred. "Goodbye Uncle Alfred; I'll miss you." With that, she turned and walked slowly toward her mother.

Fighting back the tears welling in his eyes, now that they were all alone, Alfred turned to his ward. "Well, I recommend we prepare that supper."

Ten Years Later

Sitting on a bench on upper 5th, Olivia couldn't stop the flood of tears. It had been just a year since her mother kicked her out because she was seeing one of her students, and just yesterday, she found out her boyfriend was cheating on her. Not knowing what to do, she left, sleeping at a local Church shelter.

I'm now completely alone. Ever since she left Wayne Manor, she rarely saw her cousin Alex, and could count the times she saw Bruce, her best friend, with her fingers. With her mother slipping into drunken stupors more and more often, Olivia had no idea how her life could get any worse. And yet I did. What am I going to do?

Just then, she felt a piece of paper caught on her leg. Bending down to pick it up, Olivia saw it was a recruiting flyer for the Gotham Police Department. She looked at it in disgust; the GPD was notorious for its corruption and ineffectiveness. They were almost universally owned by the various mob families, notably the one ran by Carmine Falcone, the man she was sure arranged for the rape of her mother. "What God? This is what you send me!" She was about to toss the flyer in the trash can when she stopped herself. What else can you do? She was good at self-defense (any woman living in the Narrows had to be), and had no better non-criminal prospects. Wiping the tears from her eyes, Olivia sighed. "Well God, I guess you're looking at the newest member of the GPD.

A/N: Well there you have it. I know it follows the story line but it'll get more interesting later. Let me know what you think!
