Woah. Hold it right there. This isn't your typical crossover. No sir. If you want to understand in the slightest what is going on, please read Mystical Raven's Lilo and Stitch stories before reading this one, because it heavily uses characters and concepts from her stories. With her permission, of course.

…

Have you read her stories?

Well, if you're reading this, I'll presume you have, so go ahead. But first, and I can't believe I still have to say this:

Two figures were glancing at a computer screen in the middle of a large chamber. The chamber was full of strange tanks, with purple-red cubes floating within. Another figure whistled a merry tune as it cleaned said tanks with a rag, decidedly ignoring it's comrades behind it.

"What about this one, boss?"

"Hm… Not enough civilization. We need SOMETHING to conquer."

"Okay, what about this one?"

"Too steampunky."

"This one?"

"Why is that ninja wearing orange!?"

"…Uh, next o–"

"AGH!" The second voice screamed, slamming it's hands on the desk. "None of these are interesting!"

"Well, boss," The first voice replied exasperatedly. "We are randomly looking into parallel universes. What, exactly, were you expecting?"

"Oh, I don't know, something with enough technology to take advantage of, but also with some kind of unique power I can exploit!" The second voice growled. "The empire is strong, but there's always the chance that there will be something MUCH stronger out there!"

"Doctor," Another, deeper voice said. All three figures turned around. There was another figure, this one glowing a deep red, floating before them.

"Hm? What is it?" The Doctor asked.

"You may wish to look into this." The figure held out it's arms, exposing a magenta gemstone embedded in it's chest. The gem began to give an eerie red light as the monitor began to flicker, before changing to another screen.

"Hm…" A grin split the Doctor's face as he began to stroke his cartoonishly long, thick mustache. "Yes… This looks interesting…"

"Do you wish to try with this one?"

"Yes… Infinite, gather the Chaos Emeralds. Orbot, get the stone from it's containment."

"Understood/Yes, Doctor."

"Hehehehe… OHOHOHOHOHO!" The Doctor laughed maniacally. "Get ready, alternate universe! Prepare to witness the brilliant scientific mind of Dr. Eggman!"

"Stella?" Angel turned around, having noticed that Stella's head had shot up, as if she had noticed something. "Is there something wrong?"

"…Nothing," Stella shook her head. "I just thought I'd heard something."

"Oh," Angel shrugged. She then turned back to the mirror, adjusting the floral-looking bow tying back her anttenae. "Do you think he'll like this?"

"Of course!" The black, white-striped experiment smiled. "I think it looks really good on you!"

"Thanks," Angel smiled, before looking slightly disturbed.

"Angie?"

"I don't know… I've just got this… Really bad feeling for some reason."

"Oh, silly," Stella smiled. "I'm sure your date with Stitch will go just fine."

"It's not that…" Angel started. "It's just…"

"It's just…?"

"Nevermind," Angel shook her head. "Well, I'm off!" With that, she went for the door. Stella waved her off, trying to ignore the vague sense of dread that was building up in the back of her mind as well.

Cut

Stitch didn't like waiting. Well, normally, at least. He was a rather impatient fellow, see, something he seemed to get from his mother. This was somewhat ironic, given that when most people see the color blue, which his fur was, they'd usually think of someone who was melancholic or laid-back.

He did have exceptions, though. Like waiting for Angel to come. That was something he could wait for. If he was waiting, then that meant she had something planned. He usually liked that.

He could also wait if it meant having to meet Odin. Yeah, he really didn't want to do that. Not after hearing the, uh, horror stories involving him. Doubly so for coming out of Fang and Slang's mouths. Grinning mouths, at that. He shuddered at the thought.

He could also wait for baths, though given his (justifiable) aquaphobia, that was understandable.

"My liege… My lieges…" Stitch groaned. He definitely couldn't wait for… He didn't really know how to describe it, but 'shadowy grotesque abomination' was close enough. He couldn't wait for that… Thing to leave him alone. It seemed harmless, if completely freaky, but it seemed to follow him everywhere. Apparently, Roy and Zack had the same problem with it. Based on the (lack of) reactions of the people around them, he presumed that most people couldn't see it.

But that was a problem for another time. For now, he was waiting for a certain someone to-

"Stitchie~!"

'Oh, speak of the devil. Or, rather, speak of an Angel, and she shall appear.'

"Hey, Angel," Stitch smiled, decidedly ignoring the eldritch abomination behind him. "You ready?"

"Yeah, I- Stitch, is something wrong?

"…" Stitch face-palmed. Of course she'd notice it. How couldn't she?

"…Stitch?"

"No," He sighed. "I was just thinking about something."

"Darkness… Coming…" That was hard to ignore. Angel evidently heard it too, and they both turned to the source.

"Excuse me?" Angel asked.

"Blind to the world…" It said, seeming to ignore her.

"O-okie-taka…" Stitch backed up a bit. Before turning to Angel. "I think we should go."

Angel nodded in agreement, trying to supress her, once again, rising bad feeling.

"The Ruby… Hides the truth…" Both of them decidedly ignored it, before taking off on their own, oblivious to the magenta-ish, glowing gemstone that had appeared directly in front of the creature.

And then it began to make a strange pulsing noise.

Both of them swivelled around to face the strange gemstone.

"…"

"…"

"…"

"…Hey, Angel?"

"Yeah?"

"What the blitznak is that?"

"I have…" Angel blinked. "No idea…"

And then, seven different colored, diamond-cut gemstones suddenly flashed into existence, orbiting the magenta ruby (Stitch was certain that it was a ruby), before it suddenly began to shake. Emitting a strange, distorted garbling noise, a wave of energy suddenly erupted from the ruby, sending the other gems flying to parts unknown and discoloring everything around it.

"H-Hey!" Stitch shouted, suddenly being pulled from the ground.

"W-W-What's happening?!" Angel yelped, being pulled up from the ground as well. And then, everything began to distort around them. The world flashed white, before fading completely from view.

After a moment, however, the white faded to black. For a moment, neither wanted to open their eyes. However, the distinct sound of a nearby explosion jolted their eyes open.

"What the-!?"

Stitch couldn't get out the words. Angel herself went silent in shock. Around them, the ruined remains of apartments and townhouses, a far cry from the beautiful scenery of Kauai. A fireball came in from out of no where and slammed into one of the buildings, causing them both to jolt.

"Were we teleported…?" Angel pondered, almost speaking in a whisper.

"…I don't know," Stitch admitted. He then pointed to the left. "Look, that's Mrs. Hasagaia… Mrs. Hasasagawa… Mrs. Hasaguana… Hasabara… Uh… That looks like her fruit stand."

"That does," Angel admitted. "But wait, then… I… Uh… What's going on here!?"

"Well," Stitch let a small smile tug at the corners of his lips. "I guess we'd better find out!"

The duo quickly went running down the only path that was (Mostly) debris-free. They came up to a terrace, where they saw what looked like massive – as in, skyscraper-sized – vaguely egg-shaped robots tearing through the city.

"What are those!?" Angel gasped.

Stitch growled. "Dead when I get my claws on them!"

They kept following the pathway, which lead to what appeared to be a spring. Deciding to just keep going, they leapt onto the spring and were sent rocketing up, and onto what appeared to be a small apartment building. From there, they were able to see the sunset casting it's rays onto the ocean.

"So, we're still on the island," Stitch noted. "You can recognize the shape of it, at least."

"Okay, but that still doesn't explain the city," Angel responded, as the two took off across the rooftops. They went down a slope, rocketed up, and then went down another slope. Continuing forward, they stopped for a moment when they saw what looked like golden rings floating in mid-air.

"What are-?"

"I don't know," Angel admitted. "But they seem harmless." With that, Stitched grabbed them and they moved forward.

It was then that they came across odd, white robots that-

"Are those shaped like EGGS!?" Stitch howled with laughter, before effortlessly catching a plasma shot from the one in front and throwing it back in its face, destroying it instantly. The other two were dispatched just as quickly, seeing as large branches grew from a pair of small trees that had been growing to the side, and flung them elsewhere.

Next their path branched; one lead back down to ground level, and another lead them to another spring. They decided on the spring path, and picked up another ten rings.

After leaping up onto another building, their next obstacle was a strange loop-de-loop that was situated at the end of a slope. Stitch smiled, and curled into a ball before rocketing down the slope, through the loop, and into…

"Wait a minute, Stitchie!" Angel called. "I can't do that!"

Stitch slowly came rolling back. "You can at least run through it…"

"Uh, hehe…" Angel blushed a little, before doing just that, grabbing some more rings in the process.

She came to regret that, seeing as there were more robots right at the end of the slope. And she was moving too fast to stop herself from crashing into them.

Thankfully, Stitch had resumed his 'Spin Attack', as Angel had coined it, and shot past her, easily cleaving right through the metallic soldiers like a hot knife through butter.

"That looks useful," she noted, just as Stitch uncurled and retracted his quills.

"It is."

"Think you can teach me?" Angel smiled a bit.

"Maybe," Stitch shrugged. The two then took off again, coming across another spring, which, when they jumped on it, lead to another spring. Jumping on this one sent them flying over several buildings, and onto a brick road.

Running further down, they came across a lone robot, which, as expected, was easily destroyed by a charging tackle, courtesy of Stitch.

The road sloped downward before, to both of their complete confusion, twisting into a corkscrew. While it wasn't hard to run through, they had to wonder what the city planner was smoking to come up with that.

Anyway, the corkscrew dropped them off onto another slope, which lead to, you guessed it, another loop with robots at the end, prompting a spin attack from Stitch. At the end of the line of scrap metal was another spring, which sent them flying towards what looked like the town square.

A pair of robots were advancing on a lone figure. The figure held out its hand. Immediately, all of them froze in place. But before anything could happen, Stitch and Angel came down on them, instantly trashing them.

"Oh, thank you," The figure sighed. Stitch turned around, and smiled.

"Aurora?" He asked. "Glad to see you're here…"

"Stitch?" Aurora turned around, and sighed a breath of relief. "And Angel. Okay… That's good. It's good to see that you guys are okay."

"Likewise," Angel smiled, before adopting a more serious expression and gesturing to the ruined city around them. "Do you know what happened here?"

"No," Aurora shook her head. "I just remember hearing a strange noise, and everything going white."

"A strange noise?" Stitch perked up. "You mean a distorted garbling noise?"

"Yes, you heard it too?"

"Heard it? We saw the source!" Stitch exclaimed. "…I think."

"Really? What was it?"

"It was-"

"Of MY design!" All three of them sharply turned their heads. There, floating above them in a vaguely egg-shaped white hovercraft, was an equally egg-shaped man in a red coat, with the most absurd mustache any of them had ever seen before.

The three were silent for a moment, letting this new information sink in.

"…Your design?" Angel raised her eyebrow.

"MY design!" The egg-shaped man grinned.

"You?" Stitch asked.

"ME!" The egg-shaped man now seemed a little irritated.

"Good," Stitch grinned darkly. "Now I know who to go after!"

"Don't get cocky, extradimensional blue runt," The egg-man sneered. "You and your two friends are nothing compared to the might of my ultimate weapon!"

"Yeah, yeah," Stitch growled. "Whatever." With that, Stitch charged the fat fool, aiming at the smug grin plastered on the man's face.

And he would've hit dead-center, too, if it weren't for a sudden black-gold blur smacking into him at impossible speed.

"What the-!?"

There was a strange creature, flickering with red static, standing before them. Whatever it was, it had black fur, with crimson accents on it's arms, legs, and what appeared to be 6, bent quills on it's head. It also seemed to be wearing white gloves with golden bands holding the cuffs, with a similar setup being used for a pair of white/black/red SOAPs.

("'SOAPs'?" Aurora asked Stitch later. Stitch quickly explained that they were shoes that had a plate secured to the sole to allow the wearer to grind down rails. "They were a fad about ten years ago, here on earth," he had added.)

The figure glowered at them with cold, red eyes, and crossed it's arms.

Besides it, another, burly figure, with a red torso, black legs, and a tuft of blue hair, wearing spiked arm bands landed. He too, was flickering with red static.

Next was a small, flickering robot, of a similar build to the first one. This robot was primarily painted cobalt blue, with silver limbs, what looked like red shoes, and had sharp claws. Also, it's sclera were black, with red glowing orbs acting as irises.

And then, to the far side, came a strange, flickering watery-looking creature with green glowing eyes. All three of them duly noted that it's brain seemed to be exposed.

A strange, yet familiar pulsing noise caught their attention, however. It was here that a completely darkened figure, save for a deep crimson glow and purple-ish, flickering aura, floated down in front of them. They couldn't seem much of him/her/it, but they could see what looked like a mask that covered the right eye, and had a red visor that slightly obscured the experiment's view of the left eye. Said left eye was golden, by the way.

Besides that, the figure had what looked like a bushy tail, large ears, and seemed to be wearing clawed gloves, and pointed hi-top sneakers. The three experiments turned to face each other.

"Anyone else getting a bad feeling about this guy?" Stitch whispered.

"Good," Angel sighed. "Then it's not just me."

"What do you think we should do?" Aurora asked.

"Well, given that we're looking at someone who is obviously very evil," Stitch grunted. "I say we should fight him."

"We're out-numbered, 5 to 3," Angel gulped.

"True, but we've faced worse before," Stitch reminded her. "You remember the, uh, LeRoy clones?"

There was a pause.

"…True, but that wasn't going well for us, either," Angel added. She was scanning the area around them, and noticed a large hammer lying among the debris, just to the left. Quickly, she pulled it from the rubble and held it up in a defensive stance.

"We have less extreme numbers here, though," Stitch reasoned. "There's only three of us, there's only five of them. That little 'war' was about 500 vs 50,000, and we held our ground."

"Still…" Aurora turned back to the black figure. She noticed a red, glowing gemstone embedded in his/her/it's chest. "I'm getting a bad feeling about this one…"

"It's a bad idea, given that we don't know what these guys can do," Stitch agreed, before adopting a more serious expression. "But I don't think we have much of a choice here," He concluded, before lunging directly at the black figure.

He was met by empty space.

"Huh!?" Stitch turned around. The figure was standing just to the left of where it had been.

"Wha-!?" Angel blinked, trying to figure out what had just happened.

"I've never seen that kind of speed before…!" Aurora noted, stunned.

Stitch growled, and turned around to swing at the masked one.

Naturally, he ended up hitting nothing but thin air. Now pissed off, Stitch started lunging, swinging, and swiping at the figure every time it showed up. And each and every time, he hit nothing but thin air.

"Are you finished yet?" The figured asked in a deep, echoing voice. Okay, definitely a "he".

"Not even close!" Stitch snarled, before winding up for another punch.

Mistake. Big mistake. Really big mistake.

With a speed that neither Stitch, Angel, or Aurora coud even dream to fathom, let alone match, the masked one suddenly threw a sweeping kick towards Stitch's face. Stitch was unable to defend himself against it, and was subsequently flung into a concrete wall with such force that it came crumbling down on top of him.

"…Ow."

The masked one then turned to Angel and Aurora, before lifting into the air to evade the ground caving in under his feet, courtesy of Angel. He then held out a gloved hand, and fired red beams of energy at them. The two of them quickly leaped back to evade the attack, only for Angel to find herself having to adjust her path to evade a watery claw aimed right at her head.

"What are-!?" She got out, before blocking another strike with her hammer. She then swung at it, catching it right in it's brain, sending it flying back and into a wall. The thing then slumped, seemingly unconcious.

The burly red one went towards the pile of rubble Stitch was buried under, but before the other two could react, he was sent flying off into the distance by a sudden uppercut.

"Heh, loser," Stitch grinned, pulling himself out of the rubble.

"That's two," Angel said. "Three to go."

The three experiments quickly regrouped, before turning to face their remaining opponents. With the red one and the water monster both out of commission, the only ones remaining were the black-and-red creature, the blue robot, and the masked one.

"Impressive," The masked one spoke, if a tad condescendingly. "You've taken out those two. Now, do you think you can defeat the rest of us?"

"We're gonna try!" Angel said, her voice resolute. Stitch grinned at his girlfriend's words.

"So be it." The masked one snapped his fingers. The robot and the black one lunged towards them with incomprehensible speed.

Or, at least, they WOULD have, if the world around them hadn't slowed to a sudden crawl.

"Nice one!" Stitch cheered, lunging forward along with Angel at their three opponents.

That was when they both suddenly found themselves being roundhouse kicked into opposing walls by the black and red creature.

"No way!" Aurora gasped as the black one, seemingly immune to her magic, swivelled to face her.

"But," Angel gasped, pulling herself out of the debris. "Time was supposed to be stopped!"

The blue robot went to help it's compatriot against Aurora, only for Stitch and Angel to leap out at it and swing at it. The robot rolled to the left, evading both, and swiped at them with it's razor-sharp claws. Angel flipped backwards and Stitch quickly ducked under it. Small tufts of blue and pink fur were torn off by the robot's claws.

The blue robot then reared back, before a crackling aura of electricity erupted from it's body. And then, with truly absurd speed, launched at Aurora, who only had time to assume a defensive position.

Perhaps, with too much speed. The robot went flying right past her, narrowly missing her head, and ended up crashing into a wall at high velocity.

There was a pause. The experiments looked into the debris, fully anticipating that it would erupt from within and attack them. But it didn't happen.

"Did it REALLY just destroy itself?" Angel facepalmed.

"Guess it couldn't handle it's own acceleration," Stitch noted, turning back to their opponents. "And then there were two."

"And judging by what we've seen so far," Aurora noted. "They're the strongest. I mean, somehow, I think one of them canceled out my magic!"

"Yeah," Stitch groaned. "This is gonna suck, isn't it?"

"Probably."

"What's the holdup!?" The fat scientist shouted. "Get them!"

"Understood," The masked one motioned forward. Instantly, the black one lunged forward and, to their mild surprise, curled into a spinning black ball and sped towards them.

"Two can play at that game!" Stitch shouted, extending his own quills and repeating the movement. The two spike balls collided with a great amount of force, cratering the ground beneath them.

The two suddenly shot away from each other and began circling at great speed, before clashing once again, only this time, Stitch was sent careening into another wall, leaving him embedded in a crater. His eyes began to droop, and his vision began to fade.

"Stitchie!" Angel shouted. Seeing the situation had began to turn against them, Aurora's body began to emit a brilliant light. The scientist looked at his monitor for a moment, before pointing at her.

"That one is giving off a tremendous amount of energy," He noted, sounding vaguely impressed. "You may wish to take her out now, before she becomes an issue."

"Tch," The masked one grunted, just as he came down on Angel and Aurora, and, in the blink of an eye, sent both of them flying with a roundhouse kick.

Stitch's eyes shot open in an instant. He grinded his teeth together, and his eyes began to flicker a bright yellow. "YOU'LL PAY FOR THAT!"

The masked one turned his head. "Hm?"

The scientist, however, was glacing between Stitch, and his monitor. His jaw was hanging open, and his eyes were probably bulging, though his shades made it hard to see.

"W-W-What!? What's this reading!?" He shouted, panicking.

"Hmph," The black and red creature scoffed, before holding out his hand. Arrows of energy shot at Stitch, who had just pulled himself out of the wall and was lumbering towards them. Without changing his expression, Stitch walked through the volley of shots, only pausing to backhand one that nearly hit him.

"Impressive," The masked one noted, adjusting his mask. The black and red one shot forward, only for Stitch to duck under him and shoot at the masked one who, caught completely off-guard, ended up catching Stitch's fist in his stomach.

"WHAT!?" The scientist gaped, looking ready to flee. For a moment, the masked one did nothing. Then, he shot his hand forward, Stitch was sent flying back with great force, leaving him sprawled on the floor, right between the other two. He struggled to pick himself up, before his arms gave out and he collapsed.

"Ugh..." He groaned. Just as his vision began to fade, he saw a pair of pointed black hi-tops land in front of him.

And that's a wrap! I REALLY hope you've read Mystical Raven's stories, otherwise that probably made no sense to you at all. I hope you have enjoyed, R&R, and I will see you all next time. Until then, take care. See ya.
