Author's Note: This story isn't directly set into one of the seasons of Batman Beyond, but stands rather on it's on. Some info first: Melanie Walker left the city, which leaves Terry with Dana (at least for now… oh, spoilers!) as a girlfriend and Max already knows the truth about Terry and the Bat. Terry has visited Bruce Waynes old martial arts mentor and knows a lot more now about roughing it up then when he started to wear the suit. Last not least Barbara Gordon knows who the new Batman is.

Kim and Ron will be in here, along with (nearly) all characters from the Kim Possible series, although we have a quite different starting position than usual. Now, let's get going!

Kim Possible: Gotham City

Chapter 01: New to the City

Roosevelt Railway Station, Gotham City

The sun was just coming up behind the impressive skyline of Gotham City when the night train from Los Angeles pulled into Roosevelt Railway station, the main train station of the city. As usual the station was flooded with people, since in this city the rush hour lasted the entire day.

But one person seemed to be out of place, for he just stood on the side of the platform, more in the shadows of the huge main building. It seems that he just stood there to see the time passing, doing nothing, a luxury no one in this city normally had. But upon closure inspection one would have recognized that he kept a watchful eye on the officers patrolling the station and on the people leaving the train.

When he saw a young blond man stepping onto the platform he started moving, revealing himself as a well muscled man in his mid thirties. He had strong features, long blond hair with a mullet and a brown goatee. He was wearing a coat and under it a pair of jeans with oil stains and a tight muscle shirt. As he approached the blond teenager the boy tensed up and turned to face him, way before he was in talking distance. It made him smile proudly.

The young man had messy blond hair, big ears, freckles and brown eyes. He was wearing brown cargo pants and a red long-sleeved shirt. A duffel bag hung from his shoulder. As he watched the man approach he greeted him with a nod. "Hi there, Uncle Ed."

"Hi there, Ron, dude." Ed gave the boy a once over, "You're all grown up there, seriously."

Ron smiled. "Thanks, Uncle Ed."

"Come on, dude, I'll take you to the others. And, please call me Motor Ed or Eddy, uncle makes me feel way old, seriously." Ed took the duffel back from Ron and headed towards the exit. Once he stepped out into the street he turned right and stepped into an underground car park. He led them to a fast looking sports car and climbed in. After Ron took the passenger seat he steered the car out into the traffic.

Ron looked out the window and up the skyscrapers they passed. The city was alive with traffic, both on ground and in the air and alights with bright neon lights, advertisements and lighted cooperation names. Everything was huge, outsized even. He didn't remember it being so huge.

"The city's big." The blond finally said after a few minutes. "I was away for just ten years and now it's like, what, two or three times the size of Neo Tokyo?"

"About four times, I would say." Ed answered. "After all, it's the biggest metropolis on the planet. But don't worry; you'll get to know it rather quickly." He grinned. "And with your new set of wheels we'll set you up with you'll have a blast rocking the town. Chicks dig a guy with hot wheels, seriously."

"Eddy, I'm not here to dig the chicks." Ron said, turning to the big man. "I've serious business to do here."

"Hey, dude, I know that. But that doesn't mean you can't have some fun along the way." Ed answered.

Suddenly there was movement on Ron's leg, a small, hairless pink rodent emerged from his pant pocket and climbed onto the dashboard, yawning and rubbing its eyes.

"So, you still got that little rat." Eddy said smiling, before he reached over and gave the rodent a careful pad on the head. It blew him a raspberry. "And it still got some attitude."

"Rufus is into this as much as I am." Ron said, picking his longtime friend up and setting him onto his shoulder.

Eddy nodded and fell silent for a few minutes, each of them lost in his thoughts. Eddy steered the car through the maze of streets and finally turned onto a huge ramp leading to a highway.

"Ok, we're out of on the highway, let's get going. No use in loosing more time, seriously." Motor Ed pounced onto the gas pedal, making the car literally jump forward and Ron and Rufus hold on for their lives.

About half the time it would normally take later Motor Ed left the highway in one of the more neglected parts of town. Besides the street stood mostly demolished warehouses accompanied by run-down administration buildings. Finally Ed pulled into a particular sad looking hall, littered with waste and covered in graffiti's. He stopped on a special position and switched a hidden trigger on the dashboard. Seconds later a masterly camouflaged elevator lowered the car into an underground facility. Above them a heavily armored cover place closed the shaft.

After the elevator finally stopped Ed drove down the ramp and parked the car in a marked parking space. Ron could see that they were in a huge hall with a domed ceiling, refurnished to be used as a garage and workshop. They left it behind on their way to the center of the facility. Several henchmen passed them by, the usual brutish, stupid and all muscle kind of henchmen and some smarter looking guys with tools and working equipment.

"This was once a nuclear bomb shelter." Eddy said while he led Ron down a corridor. "Drew took control of it about two weeks ago and he's still pimping it up, adding extra entries, a sewer connection, security systems and several new layers of paint. This place's gonna be one heck of a lair, seriously."

They entered a big room with kitchen units lined up on one side, while the other was occupied by a group of comfy armchairs and a sofa. On a table in the middle of the room several drinks and a few used dishes stood.

"Ho, Blue, Green, look what the cat dragged in!" Motor Ed boomed across the room, claiming the attention of the two people populating it.

A blue skinned man in his mid thirties, clothed in a dark blue lap coat, stood up and turned towards them. He had a black pony tail, a small scar under his left eye and dark eyes. "Hello Ronald." he said with a friendly smile.

"Hello uncle Drew." answered Ron shaking the hand of the renowned scientist who also happened to be one of the ten most wanted felons in the country. Unfortunately for him he happened only to be number six on said list, while number four sat right in the next armchair. "Please, call me Drakken or Doc, if you must. Or Uncle. Drew is a name I got rid off a long time ago. Let me introduce my companion..."

"It's about time you let us me a say in this!" the woman from the next chair chimed in, pushing Dr. Drakken aside. She was a beautiful pale green woman in her late twenties, with long, silky black hair and luminous green eyes. "I'm Shego." she introduced herself, cocking her hip. "I'm your uncle's wife, but don't you dare to ever call me aunt or auntie, or I'll kick your but!"

With that she swooped him up in a tight hug, which left the young man with a furious blush on his cheeks and stumbling for words. With a knowing smile Shego released him. "Ahm … hello." mumbled Ron, the feeling of her body pressing against him still fresh in his mind.

Clearing his throat Dr. Drakken took again the lead in the discussion. "Shego, this is my grand nephew, so please give him some room."

In this moment another door opened and a very unique pair strolled into the room. A young afro American man about Ron's age, being a bit on the portly side, with short brown curls and brown eyes entered the room, accompanied by a leggy brunette in a short skirt and a tight tank top. She seemed to be in her late teens, had brown eyes and a tanned skin. Upon seeing the boy Ron's face split into a huge grin.

"Wade!" he exclaimed, hurrying over and high-fiving the teenager, who returned his grin.

"Long time, no see, Ron-Man!" Wade said, shaking the hand of his childhood friend. "Let me introduce you, this is Bonnie."

"Hello there." said the brunette, measuring the blond boy with a critical eye. "He's a cutie."

"Now don't get any ideas, Bonnie, he's here on serious business. And don't you have something constructive to do!" Dr. Drakken interfered angrily.

"No don't get all upset, I'll return to my work immediately." she sneered, running a finger up and down on Ron's arm. "But first I should give cutie here a tour of the facility. You know, the hangar, the barracks, the labs, his bed…"

Suddenly a flicker of light filled the room and a perfect copy of Bonnie appeared next to her, but it was transparent and obviously a hologram. "You have work to do, so leave him alone already!" the holographic Bonnie said with impatience, indicating the door through which the original one had entered.

"Ok, ok, Bon-Bon, don't blow a gasket … I'll see you later, sweetie!" Bonnie purred and left the room, leaving a dump struck Ron behind.

"What… Who… Why…" he stumbled, being overwhelmed by so much female attention.

Wade grinned and led the blond to a chair, while Ron's eyes darted back and forth between the now closed door and the hologram. "Bon-Bon is the artificial intelligence of the central computer core." he explained. "With the amount of hardware Dr. D implanted into the lair I had finally enough computing capacity to both install Bon-Bon and program Bonnie. She's the system avatar, an independent android and backup system for the central core. At the moment she leads the work crews repairing the lower levels."

"It would have been nice to ask before you did it." Dr. Drakken mumbled. "And I don't really know where you got the ideas for Bonnie's attitude program, that girl definitely has some issues."

"High school memories plus 20 percent of evil seductress." Wade said. Seeing the stares the others gave him he shrugged: "Hey, I'm a teenaged male, so don't sue me. Bonnie's more or less a mix of several persons I went to class with last year. She's really nice if you get know her better. And she's picky."

"She's not nice to me!" Drakken said gruffly, crossing his arms and blowing the young man a raspberry.

"Very mature!" Shego said grinning and planted a kiss on her husband, who instantly came back with a silly grin. "And by the way, I like her!" The grin disappeared.

"Me too, seriously!" Eddy said grinning.

"I've not seen you getting close to or hitting on her." Drakken said.

"Well I did, just yesterday. And she hit back, and dude, she's got one mean left hook, seriously."

"Let's get down to business." Dr. D growled and sat down, urging the others to do the same. "We all know why we are here, so let's cut the chit-chat and go straight to the point: Ron, are you serious you want to go through with this?"

Ron, who had watched with fascination Bon-Bon taking a seat, turned his gaze to his uncle. "I'm deadly serious, Uncle. I may have been six years old but I was serious. I promised on the grave of my parents that I'll come back and hunt their murderer down. Isn't that the reason you send me to Yamanouchi in the first place?"

"It was, but you must be aware of the consequences!" Shego interfered. "If you pull this off there might be no way back. A life of crime is not suited for everybody."

"My sister sure wasn't inclined for being a villain." Motor Ed said into the staggering silence. "She was the first of the family to go legit and to have a real life, seriously."

"And it got her killed!" Ron answered angrily. "She and Dad made a scientific discovery they were murdered for and I'll not let the guy who did it escape. You told me that if I train for ten years and still want vengeance on their murderer you'll help me!"

"I said it and I'm true to my word." Drakken continued with an even and calm voice. "We just want you to know that this isn't easy."

"I'm well prepared and I'm ready." Ron said. "Now where do we start?"

"As you and your calling are the reason why we are here you'll be the one doing most of the work. The trail is more than cold; it's a frozen trail leading across the icy planes of Antarctica. We'll have to do a lot of digging in other people's dirt, so this calls for the sneaky approach, for covert missions and inside jobs."

Ron smiled coldly: "That's a ninja's job. My job!"

"Exactly. Shego will be your backup on the missions, while Wade will do the surveillance and the data crunching. I'll come up with ideas for the necessary equipment and Eddy will construct it." Drakken stood up and started to pace up and down, entering what Shego called 'rant mode'. "We'll be with done with the setup of the lair in a few days. Then you'll start training with Shego, she'll test your skills and bring you up to date with your equipment. Motor Ed will show you how to drive and fly while Wade gives you the latest news on computers."

Ron paled hearing the tough program they had laid out for him. He was a good student, one of the best Yamanouchi had seen in years. But he still disliked extensive learning and probably would do so for his entire life.

"We have an apartment for you in the city and we have a place in a local high school starting with the next school year." Drakken continued.

Ron groaned.

"You need to have some sort of cover for your stay here in Gotham." Wade said. "The officials are very attentive towards youngsters who cut school. That's some attention we don't need. Besides, this count's for me too, so we'll be living together."

Ron nodded in agreement. "Of course you're right. I'll play along seeing that it's necessary." He stood up. "Now can you show me my room, I couldn't sleep at all on the train and I'm getting tired."

"Sure". Wade stood and led Ron to his quarters. Before he left he said: "I'll come back in a few hours and we can get started. And one more thing, you'll need a secret name, a call sign for the missions. You should think about it and tell me in the next days."

"I have one." Ron answered. "Call me Oni. Call me a demon."

Kim Possible stared out of the window, taking in the surrounding scenes. The car was stuck in a traffic jam because of an accident. It was the usual Gotham City traffic chaos, while on the sidewalks people rushed past the car, each and everyone looking harassed. Above them seemingly dozens of hover cars, suspension railways and the occasional police chopper passed by. All around them skyscrapers streaked into the midday sky, literally dwarfing the impressive ten floor apartment buildings that made up the bulk of the inner-city residential areas.

"It can be pretty overwhelming when you're here for the first time." said the woman driving the car.

Kim turned around and looked at her, seeing her mother in the driving seat. But an instant later the picture wavered and vanished and instead of Anne Possible smiling at her Kim found herself face to face with her aunt Mary. Mary was only one year older than her mom, had the same auburn hair and the same built, an attractive woman in her late thirties. Bit instead of the blue eyes, like her mother had had, Mary's were green. Kim knew that occasionally on family reunions some distant relatives had mistaken Mary to be her mother.

Kim felt tears welling up in her eyes and instantly turned back towards the window. She had enough of crying, thank you very much! She had to be strong, her brother depended on her.

(X)

Mary looked at her niece, while she started to move the car through the now rapidly dissolving traffic jam. The last two weeks had been pretty overwhelming, things started to happen very fast and Mary hard hardly any time to breathe and clear her head for more than a few hours.

Two weeks ago her sister Anne Possible and her husband, Timothy, had died in a plane crash on their way back from a science convention on the west coast. Mary had gotten one of her best friends to watch her sons and had traveled immediately to Middleton, a city in the Middle West. There she had to take care of a ton of things, taking care of Anne's children and what would become of them was top priority.

Mary still marveled at the unwavering endurance Kim had shown during this last two weeks. She had helped with the funeral, co-supervised the dissolving of the Possible household and had looked after her younger brothers, acted as their anchor in this most difficult time. She was really mature for a girl her age; with strength of character some adults didn't posses.

Mary had taken up the responsibility for the three children, just like Anne had wished in her last will. She hated to take Kim and her brothers from their lives in Middleton, but her own life was centered in Gotham and so she took them with her.

During this two weeks Terry, her older son, who was usually not good in taking up any sort of responsibility (with the exception of his part time job for Mr. Wayne, which he took very seriously), had shown some serious back bone. With Mary's blessing he had bought a two floor apartment near their old flat and had single-handedly planned and went ahead with their move. The new apartment had enough space and rooms for her and all the children. And since she had inherited a lot of money from her sister, as well as the children had, the apartment was already paid for. Anne and Timothy had been renowned scientist in their respective fields of work and had held several patents. The income from these was substantial and would allow Kim and her brothers Tim and Jim to pursue any dream they might have in their lives.

"It's a big city." Kim agreed with her aunt, bringing the older woman back from her thoughts. "I don't think I can get used to it."

"You'll get to know it in no time. Terry will help you and he has some friends you might want to meet. His girlfriend Dana is a really nice girl." Trying to get a raise out of the girl she continued. "I've talked with your principal and he said that you're a good student, 4.0 grade averages. And that you've been a cheerleader, a tutor to younger children and in nearly all clubs and committees Middleton High has to offer."

"It was no big." Kim said. "Everybody could do that."

"Well, maybe you want to continue at your new school."

"Maybe."

Seeing that she would get no further comments from the teenager Mary concentrated on driving, leaving the scene of the accident fast behind.

(X)

Mary pushed the door to the new apartment open and ushered the kids inside. Jim and Tim were struggling with their suitcases, but both of them had refused any help. Kim was next, carrying two suitcases with her last belongings. Behind them Mary closed the door. "Go to the corner and turn right into the living room."

Kim nodded and followed her brothers around the corner and found herself in a spacious room with a central living-room suite. Several doors and a staircase led away from the room. As she looked around she noticed two boys waiting for them.

The first, the younger one with brown hair and dark eyes, immediately raced forward and enthusiastically hugged the twins. "Hi there, you must be Jim and Tim!" he exclaimed. "I'm your cousin Matt. And Mom told me that you're totally into rockets and stuff. That's so cool!"

Jim and Tim showed small grins, the first for the last weeks. "We're on the verge to start…" Jim began. "…our greatest project ever." Tim continued. "You wanna see?" … "It's in our boxes from Middleton."

Matt looked at his mom: "Can we go and take a look, please?"

"Ok, boys, but remember, no explosions in the house. Matt will show you to your rooms."

"Come with me!" Matt called and dragged the twins away to one of the doors.

After they left the remaining boy turned to Kim. "Hello Kimberly, it's been a while. I'm Terry."

Kim nodded and looked at her cousin closer. She hadn't seen him for more than four years and she was quite surprised. Terry had grown, well, that had to be expected, but Kim was sure that he was only a hair's breath away from reaching six feet. He had short, messy black hair and dark brown eyes. As he moved closer Kim, who were a trained gymnast and martial artist herself, could see that he moved with the grace of an athlete. He had broad shoulders and a trained body, clearly shown by the tight shirt he was wearing.

"Please call me Kim." she said finally.

Anne returned to the room, having put her coat and purse away. "Terry, can you please show Kim to her room, I've some calls to make."

Terry smiled and took her luggage. "Let's go then." He led the way to the next floor, where her room was on the far side of the building. He opened the door and waited while she stepped in.

Her new room was even bigger than her loft back in Middleton. It had a glass door leading to a small balcony and an incredible view of the quarter. To her astonishment and relieve her furniture was already unpacked and in position. Next to her bed a huge pile of cardboard boxes waited to be unpacked.

But one thing caught her attention, on her nightstand stood a familiar picture in a beautiful silver frame. It was her mothers and fathers wedding picture. She picked it up and stared at it with moist eyes.

Terry watched her from the door. When he had last seen her she had been a somewhat clumsy, shy and small girl with bracers. She had grown up and somehow become this beautiful girl standing in front of him. Terry knew that the cute, slender, athletic red head with these gorgeous green eyes would have quite the trouble getting of rid the jocks in school who always liked to decorate themselves with new girls.

He coughed gently, drawing Kim's attention. "I thought you might want to have the picture in your room." Seeing Kim on the verge of tears he rubbed the back of his head sheepishly. "I'll leave you alone, so you can start unpacking. I'll go and look after the boys, so they don't shoot themselves to Mars or something."

Kim nodded gratefully; she was too choked to say something. She tightly embraced the picture.

"See you later." Terry said closing the door.

(X)

The rest of the day was a blur to Kim. She unpacked a few things, went downstairs for supper and helped to settle the twins in. She retired early and found herself crying in her bed, hugging her Pandaroo, staring at the picture on her nightstand.

"I'm so sorry, Mom, Dad." she cried, her body shaken by agonized sobs. "It's my entire fault."

She cried on for an hour until she finally fell into a dreamless sleep of total exhaustion.
