The League of Extraordinary 'Toons

Chapter 1: Call me, beep me

Kim Possible slid between two pools of deep shadow, silent as a whisper. Behind her came her boyfriend and sidekick Ron Stoppable, moving as smooth as sandpaper.

"KP, aren't you just a little bit suspicious?" he asked, "An abandoned industrial estate, in the middle of the night: it's a classic ambush setup!"

"All the more reason for us to be quiet!" Kim hissed, pressing herself up against a wall. She raised her communicator.

"Wade, you got anything?" she asked. Wade appeared on the video screen, his wide friendly face creased into a frown.

"Nothing new, Kim," he replied, "All I'm getting is the same message, on repeat: 'Calling Kim Possible. Need urgent assistance.' And then the address: that's it!"

"OK, keep me posted," Kim replied,

"Be careful."

"I will," said Kim, replacing the communicator on her belt.

The industrial estate was very dark. The only light came from the occasional street lamp that had escaped the vandals' stones. Warehouses and office buildings loomed up on every side, black shadows against the cloudy night sky. It seemed unnaturally quiet to Kim; there was not even a breath of wind to stir the street litter. She and Ron continued to move along the road, black shapes flitting from shadow to shadow.

The address they had received turned out to be that of an old warehouse. The paint was flaking away from the walls, revealing patches of scarlet rust. The high front doors were still chained shut but a few minute's exploration revealed that the side door had been forced from the outside. Pausing only to strap on their night vision goggles, Kim and Ron slipped quietly through the door.

It was very cold inside. Looking up, Kim could see the places were the roof had fallen away, revealing patches of inky sky. It looked like the warehouse had not been used for years. Someone had crammed it full of empty storage containers the size of buses, locked the doors and walked away. There was no sign of life; not even footprints in the dust.

Trying to ignore how loud Ron's steps sounded, Kim began to move through the warehouse. The spaces between the stacks of containers were so narrow that the duo was forced to turn sideways to pass between them. First, they moved round the edge of the warehouse. Finding nothing unusual, they began to move inwards. They were approaching the very centre of the room when Kim suddenly froze, throwing out a hand to stop Ron.

Someone had cleared a wide space in the centre of the warehouse. In the middle was a grey headed old man seated on a chair with his back to them. Adjusting her goggles, Kim could make out the thin cords of rope binding him to the seat. Turning to Ron, she signalled for him to be quiet and stay where he was. Ron nodded.

Kim moved softly towards the seated man, ears pricked for any sudden sounds, body tensed for flight. Moving up behind the chair, she placed a tentative hand on his shoulder. There was no response. The shoulder felt cold and hard. Kim span the chair round and came face to face with a shop dummy. A mop head had been placed on top of it as a makeshift wig.

"Ron, it's a trap!" she cried. An unfamiliar voice answered from the shadows:

"Wow, you are quick aren't you?"

Kim turned. A cockerel, only a little taller than Kim and wearing a white tuxedo, emerged into the half light. Its beak seemed to shine, as if it were made of metal.

"I gotta say; I wonder why the boss is so interested in you," he said, "But orders are orders. Goodbye, Kim Possible."

The cockerel clicked his fingers. The shadows around Kim's feet began to bubble like the surface of some boiling liquid. She tried to step back but found that she was surrounded on all sides.

"Kim!" Ron shouted.

"Ron! Don't come any closer!" she called back. Suddenly the shadows gave a great heave and a ring of strange creatures leapt up out of the floor. They were quite short, black as pitch, with long, supple limbs. Their heads were long, tapering into twin points that hung down at the back like a jester's cap. They had no faces; only two round yellow eyes that glowed like lamps.

Kim did not wait to see what they would do. She aimed a kick at the creature in front of her. To her surprise, it vanished before her foot even made contact. It was as if someone had cut its legs from under it, dropping back into the shadows at its feet. Kim bounded through the gap she had made, towards Ron. Another of the creatures leapt at her from the right. She aimed a dismissive punch at it, expecting it to vanish as easily as the first. To her surprise the creature turned her blow aside and countered with one of its own. Its arm lashed out, struck her in the stomach and sent her flying into the side of a container.

Ron rushed to put himself between Kim and the shadow creatures. Two of them came at him at once. He fended the first one off but the second swept his legs from under him and hurled him down beside Kim. Kim and Ron scrambled to their feet, their backs to the container. The creatures loomed up before them, a row of yellow orbs in a wall of night.

Suddenly, a beam of light flashed past them. It struck two of the creatures, piercing them like a lance and reducing them to a cloud of dark smoke. The others fell back as a small, dark shape rushed forward, a golden blade flashing in its hand. The creatures had only retreated a few steps when they turned and pounced on the newcomer. For a moment all that Kim could see was a writhing mass of shadow. There was a series of explosions. The air around her was filled with smoke. As it cleared it revealed the little figure standing alone in the middle of the warehouse. There was no sign of the cockerel or the shadow creatures.

Kim took a tentative step forward. Readjusting her goggles, she stared at the stranger that now stood before her. He was a mouse, a head shorter than herself, wearing a red jacket and shorts with yellow trainers on his feet. He had a round, open face and two large round ears on the very top his head. In his right hand he held a strange weapon. It looked like a fusion between a sword and a key. Its guard was silver and the golden blade glowed softly with an inner light.

"Gosh, I'm sorry," the mouse said in a high falsetto, "I'd hoped to get here before they did. They're moving faster than I thought."

"Who are 'they'?" asked Kim.

"The bad guys," said the mouse.

"You mean like that chicken we just saw?" said Ron.

The mouse looked startled and span round. His ears twitched from side to side like little satellite dishes.

"Hold on," said Kim, removing her goggles to speak with the mouse face to face, "what – I mean, who are you? Did you send that message?"

"Shh," said the mouse, pressing a finger to his lips, "not here. We don't know who might be listening. Come with me; I'll take you somewhere safe."

The mouse did not wait for a reply but trotted off through the containers. Kim glanced at Ron, who shrugged. Kim sighed. She thought she would be used to surprises by now; her career as secret agent-for-hire had provided many. This night was one of the strangest she could remember. There seemed to be little she could do except go with the flow.

The mouse led them out of the warehouse and across the industrial estate. He moved even more cautiously than Kim, halting every few steps to check that they were not being followed. They eventually reached a car park on the far side of the estate. The mouse broke out from the cover of the buildings and sprinted across the tarmac surface. Kim and Ron were close behind him.

At the far end of the car park was an old port-a-cabin. It was crouched in the deepest shadows beside the wire fence. The door was hanging off its hinges and Kim could not see a complete pane of glass in any of the windows.

"What is going on?" she hissed but the mouse's only reply was to press a finger to his lips. Turning to face the port-a-cabin, he waved the oversized key above his head three times.

In less than a heartbeat, the port-a-cabin began to change. It appeared as if there was another, larger building inside trying to break out. The prefabricated walls, which only a moment ago had seemed so solid, began to swell and contract as if they were no stronger than paper. The new, inner shape pushed its way out, swallowing up the dull green walls and replacing them with proud scarlet. The windows became bright yellow stripes. The door was pushed aside to make way for broad, white wings. At the rear flourished a jet exhaust and on the roof emerged a dome of blue crystal. In less time than it would take to describe it, a gleaming rocket ship stood before them. Kim and Ron's jaws dropped.

"Quickly, come aboard," the mouse instructed, moving forward to grasp the golden ladder that had descended down the side of the ship. The crystal dome at the top opened with a hiss and the mouse dropped inside. Kim and Ron exchanged a shrug and followed the mouse aboard.

Underneath the dome was the ship's cockpit, gleaming in chrome. The control panel was studded with bright buttons, like so many precious stones. There were three seats; the pilot's, in front of the wheel and two for passengers behind it. At the very rear of the cockpit, below the hinge of the dome, was a ladder descending into the ship itself. Kim climbed into the cockpit just in time to see the mouse's round ears disappearing through hole.

Kim had been aboard many aircraft in her life, and several spaceships, but this one was easily the strangest of them all. The floor of the cabin was covered in a thick green carpet; the walls with flowery yellow wallpaper. There was a gramophone player, a wardrobe in one corner, and a dresser next to a roaring fire beneath a stone mantelpiece. In the middle of the room were a group of squashy armchairs grouped around a coffee table.

"Wow, it's so…" she began, trying to think of a polite way to describe the cabin.

"Cosy!" Ron finished for her.

"Ain't it just?" said the mouse, without a trace of irony. He led them across the cabin towards a figure standing beside the fireplace.

"Your Majesty," the man said, "You found her!"

Clean: that was the first word that came to Kim's mind when she saw the young man. He looked like an advert for men's healthcare products, all perfect white teeth, square jaw, slim hips and rippling muscles. He was wearing a blue cape, a breastplate of brown leather and a pleated skirt of leather plates.

"Your Majesty?" said Kim, confused.

"King Mickey, at your service," said the mouse. He looked embarrassed at having to introduce himself as such.

"And this is Hercules," he said, indicating the tall man beside him.

"Whoa-ho! Just wait a minute!" said Ron, "You mean to say this is the Hercules: strength of a god, the greatest hero of all time?!"

"The one and only," said Hercules with a smile so bright it almost shone. He reached out and shook hands with Ron, who could not suppress a whimper of pain as the iron grip closed on his. Kim, however, was made of sterner stuff and managed to keep her eyes from watering.

A new, unfamiliar voice spoke from the mantelpiece:

"Hmph. I still don't see why you dragged us all this way, Your Majesty. As far as I can see, she's just a slip of a girl."

Kim leant round Hercules to confront whoever had just spoken. It took her a moment to spot him. Unlike Mickey, he was a mouse-sized mouse, sitting in a miniature armchair on the mantelpiece. He had pale brown fur and was wearing a violet dressing gown.

"That's good, coming from someone who came free with the breakfast cereal," Kim said waspishly. The brown mouse raised a disdainful eyebrow and sucked at the miniature pipe in its claw.

"How vulgar. I say we leave her here," he said.

"Kim Possible, Basil of Baker Street," said Mickey hurriedly in a tone of almost desperate cheerfulness.

"Charmed, I'm sure," said Kim.

"Likewise," said Basil. Their voices dripped with sarcasm.

"And that's just about everyone," said Mickey, "except…"

"I am the terror that flaps in the night!" boomed a voice, interrupting Mickey "I am the crust on the pie of justice! I am…"

There were some muffled curses. A door at the far end of the cabin rattled for a few seconds and then burst open, sending a figure in purple tumbling head over heels onto the carpet in front of them. Staggering to its feet it announced, rather woozily:

"I am Darkwing Duck!"

He was indeed a duck. Standing a little taller than Mickey, he had white feathers and wore a long cape, wide brimmed hat and a purple mask above his beak.

"Now hold on!" Kim shouted. The situation was getting too strange for her. Everybody in the room froze.

"Your Majesty," she said, turning to Mickey, "what is going on here? What's with this… this menagerie?! And why are Ron and I here?"

"We'd better sit down," said Mickey, "this could take a while."

Eventually, after everyone had taken an armchair and been served hot tea (in a china cup, of course), Mickey began to explain:

"OK, you've probably worked out that we're not from your world."

"No kidding," said Kim.

"Well, there are lots of different worlds out there. Every star in the sky is a distant and different world. Gummi-ships, like the Excalibur, allow people to travel between them. Now, every star has a heart, just like a person. The Heartless, the creatures that attacked you in that warehouse, want to find and devour each and every heart in the universe."

"And that's bad, right?" said Ron.

"Oh yeah," Mickey said, "If the Heartless take the heart of a person, that person becomes a Heartless like them. If they take the heart of a world, that world vanishes, along with everyone in it. The Heartless were created by a madman named Xehanort, who wanted to rule all the worlds."

This was starting to sound very familiar to Kim and Ron: defeating megalomaniacs with ambitions of world conquest was their bread and butter.

"So, you want us to stop this Xehanort?" said Kim.

"No, he's not a problem anymore" said Mickey, "Three friends, named Sora, Riku and Kairi, fought with me against Xehanort using powerful weapons called Keyblades."

Mickey held up the golden key he carried for them to see.

"About six months ago we defeated Xehanort for the last time and my friends returned home to their own world. Not long after that, however, things started to go wrong. Y'see, every world is supposed to be separated by an invisible wall which stops people crossing over to other worlds. It's what preserves the World Order."

"And the barriers have gone?" said Kim.

"Yes," said Mickey, "Villains have started moving between different worlds and they're causing all sorts of trouble.

"About a month back, I sent a letter to Sora and his friends to ask them to come and help me find out what's happening to the barriers. There was no reply. So, two weeks ago, I sent my court magician and the captain of my guard to deliver the message in person. They were nowhere to be found."

"And you want them found," Kim concluded.

"Yes," said Mickey, "but more than that. I'm sure that the two are connected: the barriers breaking down and my friends disappearing. Whoever or whatever did this has gotta be real powerful; I don't think I can deal with it on my own."

"Missing persons? No problem!" said Kim brightly, putting her cup down and standing up "When do I start?"

"You mean: when do we start?" said Mickey.

"We?"

"I'm forming a League," said Mickey, "A team of extraordinary people to find Sora and his friends. And I'd like you to join."

"A team… Wait a second," said Kim, with mounting horror, "you mean team up with these guys?"

"My apologies if we don't meet your high standards," said Basil icily.

"I for one am much happier working solo," said Darkwing grumpily.

"Please, guys, don't fight," said Mickey sadly, his ears drooping like wilted flowers.

"I need you all," he continued, "Hercules, for your strength; Basil, for your mind; Darkwing, for your stealth and Kim, for your skill. I need you all. We all need each other if we're gonna do this."

Basil and Darkwing did not look any more cheerful but they kept silent.

"So, Kim, what do you say?" said Mickey.

Kim's immediate reaction was one of horror: she doubted that there was a competent hero between the four of them. The mission would be a shambles. However, she reflected, Mickey had successfully fought off the Heartless, where she and Ron had failed. He at least had some skill. Hercules looked like he could handle himself in a fight, too.

Could she really turn down Mickey's request? She had never refused to help someone before. After all, she advertised on her website that she could do anything. Could she live with the shame if she turned them down?

Kim sighed:

"OK. I'm in."

Mickey gave her the widest smile she had ever seen on anything that was not a crocodile.

"Ron's coming too, right?" Kim asked hurriedly. She wanted at least one other normal person on this mission with her. Semi-normal, she corrected herself.

"Oh no!" said Ron, shaking his head firmly, "I don't think this is for me."

"What?!" Kim rounded on him angrily, "Ron, what're you saying? You can't break up Team Possible!"

"You're more than welcome to come," said Mickey.

"KP, look around you," said Ron, "You're not gonna need a sidekick on this one: you're gonna have Hercules himself watching your back! Besides, Rufus doesn't like space travel."

"But Ron…" Kim began.

"Kim, this is a team for extraordinary people," said Ron softly, putting his arms around her, "I'm just a regular guy."

"No you're not."

"Yes I am. Come on, think about it: you're gonna visit other worlds! It'll be fun!"

"Not without you," said Kim sulkily.

"You can tell me all about it when you get back," said Ron. He leant forward to kiss her. There were some embarrassed coughs from the others and shuffling of feet but Kim didn't care.

"See ya later," said Ron, stepping back and breaking the embrace. He crossed the cabin and, giving her one last wave, climbed up the ladder and out of sight.

Kim went and sat in the bathroom for a few minutes, where no-one would see her cry. When she returned, she found Mickey pouring over a strange map of interconnected dots. The others were sitting in their armchairs, talking quietly.

"So," said Kim, approaching the table and trying to look more confident than she really felt, "what's the sitch?"

"Pardon?" said Mickey

"What's the plan?" Kim explained, "Where do we start?"

"First, we gotta recruit the last member of our League," said Mickey.

"And who's that?"

"Well, he was born John, Lord Greystoke but I believe he answers to a different name these days: Tarzan of the Apes."

Author's note: On the suggestion of lesharostormraven, I have decided to add a little note to each chapter to tell people where I took some of the more obscure characters from.
