The six superpowered characters flew through the city. There was a seemingly endless stretch of buildings on either side of them, some of them damaged from Heartless attacks.

Blossom took the lead. Ed was behind her, being carried from his huge arms by Bubbles and Buttercup due to being the only one without the power of flight. Sora and Eddy took the rear. The spiky-haired junior hero hung onto his Keyblade for dear life, fearing falling to his death. Eddy kept his gravity-altering spell going.

Blossom half-turned her head "We're almost there, guys!" she declared.

The tall buildings gradually began to appear less and less as the group entered a suburban area filled with two-storey houses.

"Better be," Eddy murmured, straining from keeping the Gravity spell going, "I can't keep myself airborne much longer."

Up head, Buttercup inched closer to Blossom so the others would be out of earshot when she asked, "Why are we letting these noobies join in with us?"

"Oh, come on, Buttercup," her sister responded, keeping her voice low purely so her sibling wouldn't tell her to lower it. "I already told you; even if we have what it takes to defend the city against the Heartless, the 'noobies', as you call them, can and will make things much more easier for us in the long run."

"Okay, I admit their powers are pretty cool." Buttercup glanced behind her before finishing with, "But there's something weird about them."

"You always say that about everyone who isn't against us these days, Buttercup."

"Ugh!" she threw her sausage-shaped arms upwards in a huff. "I give up!" she hissed. "Let 'em tag along for awhile, before giving them the boot."

Bubbles suddenly popped into the conversation. "There it is, girls!" she pointed forward at a white, rectangular house with circular windows. "Home sweet home."

"That must be her house," Sora guessed.

"No duh, Sora," Eddy grumbled.

Everyone touched down on the house's front lawn. The area seemed suspiciously quiet, even for a residence in a suburban area. The six walked towards the home's red front door. The girls led the way.

Buttercup suddenly stopped in mid-step, and held her arms out to halt the others behind her. "We have a problem," she uttered.

Blossom--who was the only one in front of Buttercup--stopped and turned around. "What is it now, Buttercup?" she asked, expecting another attempt at making her dismiss the idea of having Sora, Ed, and Eddy join.

"Him," Buttercup pointed.

All eyes fell on Ed.

The behemoth smiled down at her from the back of the group, "Don't worry; I always wipe my feet before I go in."

Everyone mutually stared at him.

K-K-K-K-K-K

Five minutes later…

Ed suddenly blinked. His walnut-sized brain must have finally processed the fact that the door was too small for him to pass through.

"Oh….," he knowingly uttered. "It's all right; you guys can go on without me." He sat his big self down, Indian-style.

"We'll be back," Blossom turned, walked up to the door, and pushed it open without even twisting the knob or using a key. "Come in," she gestured.

K-K-K-K-K-K

"We're home, Professor!" Bubbles called out as Sora closed the door behind him.

The inside of the girls' abode was a typical family home. 'Nuff said.

"Girls?!" a male voice echoed from up the stairs. A tall figure dressed in white eagerly descended the staircase, holding something in its hand.

"I'd like to introduce you to Professor Utonium, "Blossom gestured at the man, with extreme gusto.

"A.K.K. our dad," Bubbles added.

Professor Utonium was a rectangular-headed, long-eyed man. A white lab coat with a breast-pocket with writing implements adorned his lean figure. His black trousers stretched into black boots (and it couldn't really be decided where the trousers and boots met). Underneath his lab coat, he wore a white shirt, neatly-buttoned. A black tie clung to his neck tightly, properly tucked under his coat. His hair, eyes, ears, nose, fingers, and thumbs were all strangely squared or rectangular in shape.

In his hand, the Professor carried some sort of bionic claw. But that didn't seem to be the centre of attention as of yet.

He frowned, "Girls! When will you listen to me?! It's dangerous out there, what, with all those…….Heartless running amuck all over Townsville."

Bubbles' face saddened like a five-year-old's, "But, Professor! The Mayor told us that Town Hall was under attack, and we had to go and save him."

The Professor regarded her words, "I'm surprised the Mayor is still alive, and hasn't lost his heart; by now, I'd expect ninety-five percent of Townsville's population to be gone." He suddenly noticed Sora and Eddy, "Who are you?"

"They're the ones who helped us fight off the Heartless," stated Blossom. "There's another one outside, but he was too big to fit through the door."

The Professor raised a rectangular eyebrow, "They don't look familiar."

Sora simpered. His eye mask arched downwards, "We're from a city very far away."

Eddy nodded. "We came to find Double D, and maybe, the Keyhole."

Utonium's eyes widened, "The what?!" He dropped the robotic arm.

Sora gasped.

Eddy suddenly realised what he had just said, and shockingly covered his mouth with both of his hands, "I'd expect that from Ed."

"'Keyhole'?" Buttercup remarked, looking at her sisters for an answer. Blossom and Bubbles both shrugged. "What's that?"

"There's no such thing!" the Professor exclaimed. "Certainly not here!"

Bubbles started, "But--!"

"Not another word, Bubbles!" Utonium frowned down at his on-the-verge-of-weeping daughter. He faced the girls, "From now until the Heartless disappear, you are not allowed to leave this house! Is that clear?"

Naturally, Buttercup was the first to speak, "But I didn't do anyth--!"

"No 'but's!" the Professor swayed his hands dismissively. "Now, girls, escort these gentlemen out the door, and go to your room. And do not disturb me," he bent over to pick up the machine he dropped, "I'll be busy in the lab working on my latest invention that may defeat the Heartless."

The scientist coldly turned around, walked to a door, opened, closed, and was gone.

Eddy leaned into Sora's ear, "What a geek."

"We're sorry, guys," Blossom spoke apologetically, "but the Professor can be overprotective sometimes."

"'Sometimes'???" Buttercup quipped.

"Anyway," the orange-haired girl pointed at the door, "you're gonna have to leave."

Eddy crossed his arms, "After being asked to join you to fight the Heartless???"

Blossom blushed, "…..afraid so."

"Might as well do homework, or something," Buttercup muttered. She floated up the stairs and was gone.

"See ya," Blossom waved and followed the path Buttercup took.

Bubbles remained. There was a look on her face that was somewhere between sadness and anger. Her cheerful and bubbly demeanour had practically disappeared.

"Guys, I want you to come with me somewhere," she said.

Sora blinked his masked eyes, "But…..didn't your dad say--?"

"Forget about him!" Bubbles angrily swayed her short arm. "He never lets us do anything. We'll be fine; I promise!!"

Sora heaved a sigh, "Okay. Where to?"

"Follow me," Bubbles floated past him, and stepped through the door.

Sora and Eddy followed.

K-K-K-K-K-K

"Hi, guys!" Ed greeted cheerfully. "How was it?"

Eddy raised a finger and opened his mouth to speak--

"Do we need to fly?" inquired Sora, unknowingly cutting off the mage.

Bubbles shook her head. "No need. The place I want to show you is very close by." She pointed at a random tree, and drifted to it.

The others followed.

As he got closer, Sora noticed that there was a design in the tree's bark that resembled that of a door. His hypothesis was correct when Bubbles pushed it open, revealing a staircase that descended into darkness.

"Ahh, D&D," Ed snorted

Sora and Eddy both looked at the enormous boy, knowing that he'd be too big to fit.

Ed seemed to know it as well. The frown on his face said so, "Aww, man."

"We'll be back; don't worry," Bubbles gave him a cute smile. "Let's go, guys."

Once again, Sora and Eddy silently followed, and Ed was left outside.

K-K-K-K-K-K

No sooner had they shut the door behind them and descended the spiral staircase, that Sora, Eddy, and Bubbles entered a room full of various knick-knacks. A single light bulb hanging from the ceiling provided illumination for the grotto. Several objects from other worlds were lined on levels of shelves. There was a pair of big black glasses, a metal cylinder with a switch, a long cane with a hook, a boomerang that had a bat's design, a dog's collar with the letters 'SD', and many more.

Sora noticed a specific part of the rocky wall that stuck out. It was much brighter, and had captured his eye immediately. "………"

Eddy looked the place over. He removed his wizard's hat to scratch his head. "Hmm, you've got quite a collection here, Buttercup."

"It's 'Bubbles'," Sora corrected.

Said girl hovered upwards, and gestured at the assortment of items with open arms, "Look at all the wonderful things the girls and I have collected. I think it's all from the outside world." She smiled hopefully at Sora and Eddy, "Someday, I'm going to see what's out there. I want to see other worlds." She giggled, "Hehehehe! Doesn't that sound strange?"

Sora shook his head, "Not at all, Bubbles!" He gestured at himself with a gloved hand on his chest, "I used to feel the same way."

Bubbled tilted her blonde head to the side, "'Used to'?"

"Uhh…..I mean….I still do."

"Oh, I see. Hey, why don't we try and find that Keyhole?"

"Uhh, but didn't your father say--?"

"Oh, forget about the Professor!" Bubbles snapped. "He just doesn't understand! We'll be fine, and I know just the place!"

"Will Ed be able to fit this time?" Eddy questioned sarcastically.

"Definitely."

K-K-K-K-K-K

"……………………hmmmmm………," Him humped, daintily resting his red head on his pincer.

He was in his lair….or realm, to be more precise. The world was pure white, with a single, red platform on which the demon was situated. Hundreds of T.V. screens hovered around the villain, displaying black-and-white footage of world-famous tragedies, such as World War Two. Sitting comfortably on a lavish satin sofa, Him observed one particular screen, which displayed the coloured images of Sora, Ed, Eddy, and Bubbles flying to some destination.

"So…," his voices echoed, "…it appears that Sora, Ed, and Eddy are searching for this world's Keyhole."

He shifted positions so that he was sitting up with his pincers behind his head and his booted legs crossed.

The clown grinned, "They'll never find it, and my Heartless with make quick work of them."

He stroked his goatee gingerly.

His green eyes narrowed, "But Bubbles may prove to be useful to me. Hee-hee-hee-hee-hee!!!!"

"Oh, no!!!" the Narrator screeched. "What is Him planning for our dear Bubbles?!?!?!?!"

"You'll have to wait and see," Him cooed.

K-K-K-K-K-K

Eddy gawked, "What the Hell happened here????"

They were in the forest on the outskirts of Townsville. The clearing they were in was made so by a vessel that looked like it had crashed days ago. The ship had its nose dug into the earth, and seemed broken beyond repair. There was a path behind it almost devoid of trees; the vessel had skidded for several yards, before suddenly tumbling forward over its nose and crashing.

Ed was just about as bemused, "Uhh………is it sleeping?"

Sora's eye mask had doubled in size, "Is that…….a……….?"

"Gummi ship," Bubbles--out of all people--said.

"Eddy, look!" Ed pointed at the ship's charred side.

"Holy crap!" Eddy ran over to inspect two letters. "It can't be…."

They were two D's; 'DD'.

"This is Double D's ship!" exclaimed the mage.

Bubbles blinked, "Oh, you know him???"

"That means Double D's here, Eddy!" Ed hooked a huge arm around his little friend, and squeezed him in a hug. "He was here! He was here! He was here!"

Sora looked at Bubbles, who was hovering by his side. "What happened here?" he asked, ignoring Eddy's suffocation and Ed's frolicking in the background.

"Well," Bubbles started, "a few days ago, this ship crashed here. The Heartless had long been harassing us before then. The Mayor asked the girls and I to check it out."

At this point, Ed had released his smothering grip on Eddy, and was listening intently. Eddy straightened out his neck, and opened his ears.

"When we arrived, we found this crashed ship. There was a boy, crawling out from it. He said that his name was 'Double D' and that his ship was called a 'gummi ship', but didn't want to tell us where he came from, or why he crashed, or anything else. We offered him a place to stay, but he refused, saying that he 'didn't want to trouble us'. He then pressed a button on some remote, and a smaller ship popped out from the gummi ship. He said goodbye, and was gone."

"Whoa…….," Eddy mused. "I can't believe that we just missed him."

"She said that it was a few days ago, Eddy," declared Sora. "He was here way before us."

Eddy faced Bubbles, "Anything else, you'd like to tell us?"

Bubbles nodded sweetly. "After Double D left, we asked the Professor to investigate the ship." Her face saddened, "But when he saw the ship, he got scared for some reason, and told us never to come here. We still don't know why." A tear trickled down her cheek, "He's never been this protective of us."

Sora didn't know whether to go over and hug her or not. "Uhh….," this was one thing his new powers could not help him do. "Are you alright?"

"I'm fine," she wiped her eyes. "My sisters always tell me to be strong." She sighed, "I wish I was smart like Blossom and strong like Buttercup."

"I'm sure you have something better, Bubbles."

Her eyes went all puppy-like, "You really think so?"

Eddy rolled his eyes. "For God's sake," he muttered, "…will ya cut out the mush already?"

"Let's explore Double D's ship!" Ed suddenly blurted.

"That's a great idea!" Bubbles had gone from sad to happy in a quarter of a second. "Let's do it."

K-K-K-K-K-K

Inside the gummi ship's slightly tilted cockpit…

(…where Ed couldn't go because of his size…)

"What's this?" Eddy held up an object he found down below the control room.

Simply put, the object was a flat crystal in the shape of a key.

Bubbles hovered over, and examined it up close. Her blonde head turned in the direction of the Keyblade Master, "Do you think it opens something, Sora?"

Sora politely took the object from the mage's hand, and inspected it at eyelevel. "Hmmmm……let's go back to the grotto and find out," he suggested.

K-K-K-K-K-K

In the grotto…

Sora, Eddy, and Bubbles stood in front of the section of wall that stuck out like a sore thumb.

Sora held the crystal out, and a blue glow was emitted from the mysterious sparkler. The object hovered out from the boy's gloved hand, and settled on the special section of the wall. Now, both the crystal and piece of wall were glowing in synch.

But, before the Keyhole could be revealed…

"Bubbles! What are you doing here?!"

All three's hearts skipped a beat, and they whipped around dreading the sight of one person. That person happened to be the Professor, who was frowning like a disappointed father (which he was) at his disobedient child (which Bubbles was). He was wearing the bionic claw from earlier.

Blossom and Buttercup hovered behind him. Both tried to prevent eye-contact with Bubbles.

"You've disobeyed me again!" exclaimed the angry scientist. "I told you not to leave the house!!" At that point, he had forgotten about everyone else, except for Bubbles, whose head he was burning a hole in with his rectangular eyes.

"ED!" Eddy called, eyes looking up. "We told you to stand guard!"

"Sorry, Eddy!" came Ed's voice from above, "but my mom told me to always respect my elders!"

Bubbles' big eyes shifted to her two sisters.

"Don't get us wrong, Bubbles," Blossom hovered forward, but was halted by Utonium's extended arm. "We didn't tell on you. The Professor realised that you were gone first. And when he saw Ed standing near the tree…..well….."

"We knew we were screwed," Buttercup finished for her.

"Exactly," Blossom nodded. "We're--"

"ENOUGH!!!!" the Professor shouted, causing everyone to jump.

He extended his bionic claw. The claw opened up, and a bright blue radiance grew from in between the pincers, and shot forward in the form of a laser beam. The beam struck the crystal key, shattering it to pieces.

Bubbles gasped. She looked at the Professor with tearful eyes. "How could you….?" She flew past Sora, past Eddy, past the Professor, past her sisters, up the stairs, and out the door.

Everyone was shocked.

The Professor lowered his claw, and heaved a sigh. His shoulders and eyebrow slumped. "Girls……go home."

Blossom and Buttercup hovered hesitantly.

"Now."

They gulped, and left.

Utonium then shot a paralysing frown at Sora and Eddy. The latter of the two gulped.

"Young man," Sora was addressed formally, "you're not just from 'a city very far away'; you're from another world!"

Sora and Eddy gasped.

"Aren't you?"

"H-How did you know????" Sora sweated.

"You may fool my girls, but you can't fool me; you don't know your powers from your eye mask!!" He looked at Eddy, "It's just a magical spell to help you blend in this world more; even though staying normal would have been better."

Eddy pouted with his arms crossed. "It was the first time I did it. Sheesh…"

"As the Key Bearer," continued the Professor, "you must already know that one must not meddle in the affairs of other worlds!"

"Of course I know that," Sora leaned forward and gestured, "….but--"

"You have violated this principal!!" the scientist interrupted. "The Key Bearer shatters peace, and brings ruin…"

"But Sora's not like that!" Eddy retorted.

The Professor ignored him. He seemed just about ready to leave. As he turned his back on the two, he glanced behind him and said, "I thank you for assisting the girls in defeating those Heartless, but there's no room in our city for you and your Key."

He coldly walked up the spiral staircase, and was gone.

"Don't bother with him, Sora," consoled Eddy, "he doesn't know about you, is all."

Sora didn't reply. He had brought out his giant Keyblade, and was looking at it plainly. No matter the size or shape, it was still the Keyblade he aquired on his island home.

He wondered; was the Professor right? Does the Keyblade Master really bring harmony to an end, and just create strife? By sealing the Keyholes, was Sora doing more harm than good? Had this entire quest been for nothing? Had he been going about it all wrong?

"Coming, Sora?" Eddy sauntered towards the stairs.

"…………………….yeah…be right there."

A decision was made. Sora held his Keyblade over his shoulder, and headed for the exit.

K-K-K-K-K-K

Atop a skyscraper in Townsville, Bubbles was sobbing to herself. She couldn't understand why the Professor would do such a thing as to prevent her from witnessing the Keyhole.

"Well, well, well," a scratchy voice announced, "….what have we here?"

Bubbles looked up, wiping a tear from her eye. Her eyes widened.

Three figures hovered around her. They looked like the Powerpuff Girls, in a sense. They had the same size, body shape, eyes, and lack of certain parts. However, there were a few differences; they were male, had darker colours, wore sneakers, and had different hairstyles.

"It looks like she's crying," the one in blue said. His hair was matted to both sides. "Aww," he mockingly cooed, "if only there was something we could do."

"Wait, guys!" the one in green said. He had black spiky hair, and was constantly twitching. "Maybe, he can help her!!"

"Yeah, Butch," the one in red had his arms crossed in a failed attempt at a 'bad boy' image. His orange hair was long and had many split ends. The red cap he wore was on backwards. "He could be of some help, eh?"

"Who…..who are you talking about?" inquired Bubbles.

POOF!!! Him suddenly appeared in a puff of red smoke. "Why, me of course!!" he exclaimed, his orange arms extended wide Broadway style.

The devil casually walked towards Bubbles.

"You called, my dear?"

Bubbles gasped, "Him?!" she suddenly frowned, and hovered in the air. "What are you doing here?!"

The other boys moved in for attack.

"That's alright, boys," Him stopped them simply by holding his pincer up. He gave Bubbles a clownish smile, "I just ant to help you, Bubbles."

"…….," Bubbles looked at him funny.

"It's alright," Him stated as he girlishly circled the Powerpuff Girl, "I just want to help you; that's my specialty." He pointed at the three boys, "If you remember correctly, I helped the Rowdyruff Boys by bringing them back to life."

"But they're bad guys!" Bubbles exclaimed.

Him shrugged, "So??? I'm still helping them. I got them back on my side, because I made a promise."

"And what promise was that?"

"None of your beeswax!" the boy in blue stuck out his tongue.

Butch and the one in red smacked him upside the head.

"OWIE! What was that for?"

"For being an idiot, Boomer," the red one uttered.

"Anyway…," Him went on, his voices echoing demonically, "let me guess. You want to see other worlds. Am I right, Bubbles? That shouldn't be too hard. After all, your new friends also came from another world."

Bubbles' eyes widened, "What?!"

"But……they had special help." Him leaned into the girl's face, and narrowed his green eyes. "That mysterious Key."

Bubbles gave Him a confused look.

"Now, now…cheer up, sweetie," Him stroked the girl's chin with a crimson pincer. "You have something special, too."

"……"

"Now…..listen closely."
