A FATE OF TWO WORLDS

Hello there, readers! This is my first fic, so please R&R. Constructive criticism is always welcome!
Most of the first few chapters is adapted (if not copied directly) from the P&F movie, so if you haven't watched it yet, SPOILERS INBOUND!

Another brand-new day of rebuilding had begun for the people of Republic City, who were still getting back on their feet a week after the events during the Harmonic Convergence, where Avatar Korra stopped the combined forces of Unalaq and Vaatu and saved the world from total destruction. Many of the city's folk have returned to some semblance of their regular lives, partly helped by the aid programs of the other four nations.

The early-morning sun proved just right for the daily meditation of the residents of Air Temple Island, where Korra and Tenzin, in particular, are taking a break.

"So what you're saying is," a confused Korra asks, "that there are other worlds aside from the Spirit World?"

"Apparently, yes. After you left the portals open after the Great Harmonic Convergence, researchers have detected the existence of multiple parallel dimensions." explained Tenzin. "Nobody has dared enter any of them yet, however."

"Well, I'm gonna be the first person, no, the first Avatar in history to investigate those portals!" an excited Korra replied. "It's a small step for me, and a giant leap for mankind!"

"Barring your use of a cliché statement, it's not safe out there!" a slightly annoyed Tenzin countered. "I'd like to remind you that my father and all of his past lives won't be able to help you anymore!" he added.

Despite his warning, Korra paid him no heed. "Well, I've made up my mind already. I'm leaving for the South Pole first thing tomorrow, and I'm bringing Mako and the rest of the gang along."

Tenzin, having lost to Korra once again, sighed. "Well, do you at least want to continue meditating?"

"You're on, Tenzin!"


Meanwhile, in a dimension far, far away, Phineas, Ferb and their counterparts make a crash-landing in the Resistance's underground base, with Buford-2 on top of them. The Firestorm Girls quickly tied them, with Isabella-2 doing some interrogations.

"Buford, aren't you supposed to be resisting us? And who are these two pairs of boys?"

"I was out there doing my own brand of resistance," Buford explained, "then I found them about to be caught by one of those Norm-bots. They don't seem to be from around here either."

Phineas then butts in and explains his side. "We're from another dimension! We need your help to get back!"

Convinced, Isabella-2 decides to have them untied and leads them to Baljeet-2, who was working in his own small laboratory.

"Ahem, that's Dr. Baljeet to you! I can hear your error-laden narration from here!"

"Hey, this job doesn't pay very much, so deal with it!" shouted back the unseen narrator. "As a matter of fact, I don't get paid for this stinking job at all!"

Scene pans out to show a beer-bellied teenager wearing a worn-out T-shirt and pajamas maniacally typing on a keyboard, with a lot of paper works on his desk.

"Sheesh, what a meanie!" said Dr. Baljeet. "So, moving on from that little distraction, what is it that I can help you with?"

"Oh, hello there, Baljeet!" says Phineas aloud.

"It's Dr. Baljeet! Do you come from a world where listening is not compulsory?"

Ferb raises his hand in objection, but Phineas signals for him to put it back down.

"We need to go back to our own dimension!" says Phineas. "Sadly, our remote here doesn't seem to be working properly." He presses a button on the remote, showing a pastel-colored forest on the other side.

"No, your remote is not dysfunctional. I shall explain to you. Imagine the universe and all of its dimensions as being circular. The energy between the dimensions flows clockwise. So let us say your dimension is here, and our dimension is over here." Baljeet explains. "Since you traveled with the flow of energy, you got here without much ado. Going the other way around, however, would take 8 million gigawatts of energy. That much would overload the local power grid."

"So, can you generate that much electricity?" asked Phineas.

"You should ask our leader about that." replied the self-proclaimed doctor.


Back at the South Pole spirit portal, Team Avatar gathered around Korra as she told them of the discovery of numerous portals leading to other dimensions.

"And that's the gist of it! So, what do you guys think? Ready for do some inter-dimensional exploring?"

"Um, Korra? I have a question." asked Bolin. "How do we know what or which portal to take? You said there were a lot of them!"

"Hmm, you're right, I never thought I'd get this far! We'll just peek at the portals, then decide! Now let's go! I can't wait! " replied Korra excitedly.

Team Avatar then went inside the spirit portal and gazed in awe as they looked at the many portals that showed what was happening inside them.

Bolin and Korra ran off and they peeked at some of the portals. Mako and Asami stayed behind and watched them.

"Look here! There's a kid playing with… a yellow mouse? That shoots out electricity?" stated Bolin.

"Here's a guy wearing a white hat with his pet dog! Wait, the dog is stretching itself, like a rubber band!" Korra announced excitedly.

Seeing that Korra and Bolin were having fun with looking at the various portals, they decide to give it a shot themselves.

A montage plays and shows Team Avatar checking out more portals. This goes on for a while until something catches Mako's eye.

"Hey guys, over here! There's a triangular-headed kid and a green-haired boy!"

Scene shows Phineas and Ferb listening to Dr. Baljeet's explanation of the various dimensions of the universe.

"First, an electric mouse, then a magical dog, now a triangle headed boy? How much weirder can these alternate dimensions get?" Bolin thought to himself.


Meanwhile, back at the Resistance's secret underground base...

"Talk to me about what?" said Candace as she walked in, albeit in a deep, hoarse voice. She then clears her throat. "And who put this parsnip topiary here! You know I'm allergic to those things!" Katie-2 and Ginger-2 then take away the parsnips in question. "You two, what are you doing here? I thought I told you to stay home!" she adds.

"We're not from here, other-dimension Candace. We're just trying to get back home." explained Phineas.

"I wasn't talking to you, cadet, I was talking to my brothers here!" snapped Candace-2 back, which embarrassed Phineas. Ferb puts his arm around and pats him in consolation.

"You're the leader of the resistance, Candace?" asked a surprised Phineas-2.

"That's none of your business! It's far too unsafe for you here!" ordered Candace-2. She then turns her attention back to Phineas and Ferb.

"You two! I've been spending my entire life trying to keep my brothers safe, and now their faces are all over the Doofen Channel! What is wrong with you?" she said with a hint of anger and annoyance in her voice.

"Like I said, we were just trying to get back home." answered Phineas.

"Well, what's stopping you?"

"Right now, quantum physics. Baljeet…"

"That's Dr. Baljeet! Sheesh!" shouted Dr. Baljeet from his chair.

"…over there says we need 8 million gigawatts of power so we can travel back." finished Phineas.

"Well, looks like we got work to do. Isabella, start redirecting power."

"Affirmative!"

"Gretchen, monitor the Doofen Channel. Make sure we're not attracting any unwanted attention."

"I'm on it."

"Buford, keep resisting."

"Nein! Sie sind nicht der Chef von mir! (Translation: "No! You're not the boss of me!")

"Buford, when did you learn to speak German? Anyway, excellent. We'll have you boys home in no time." concluded Candace-2.

Surely enough, in a few minutes' time, the portal remote was already operational.

"Ferb, look! It looks like home!" exclaimed Phineas happily.


Korra and the rest of the gang were busy watching the events inside the portal unfold.

"Wow, those two kids are actually time travelers too? Aren't they too young for that?" wondered Bolin.

"Bo, they're technically space travelers. But you're right, they do look too young to be doing that." Mako explained to him.

"Well, do we pay' em a visit or what? I can't wait to go somewhere!" asked a getting-more-impatient by-the-minute Korra.

"Fine, let's go in then. Ready, in 3, 2, 1!" Mako said as they prepared to go into the portal

"WHOAAAA!" they all screamed in unison.

Team Avatar found themselves being tossed and tumbled around time and space.

Phineas' hopes were quickly dashed, however, when a broadcast from the Doofen Channel came on.

"This just in," said the Norm-bot, "our supreme leader has just announced the capture of public enemy number one, Perry the alternate-dimension platypus!" The broadcast shows Perry's mugshot, then an X goes through it. "I guess we won't be seeing him anymore, except as a platyborg." The channel switches to a test pattern. "It's 3:30, we now conclude our broadcast day." "NOW GO TO SLEEP!" said a voice-over of Doof-2.

"We've got to save him!" Phineas worriedly shouted.

"Oh no, you don't. Facing Doofenshmirtz by yourself is practically suicide. You need to get back to your own dimension." retorted Candace-2.

"We're not going anywhere without him! Even though he used us as his cover, he's still our pet, and a part of our family! Right, Ferb?" adamantly exclaimed Phineas as he looked towards his brother. Ferb, as usual, nods in agreement.

"I may no longer be able to open this portal again!" shouted Dr. Baljeet from his chair. "It is very unstable! Any minor disruption will cause it to collapse!"


Meanwhile, back at the Flynn-Fletcher backyard…

"WHOA! Stacy, did you see that? It's the mysterious force!" exclaimed Candace happily.

"Now, now, Candace, I'm sure there's a perfectly logical explanation for this…" replied her friend.

"Forget logic! I'm going in and I'm gonna show it who's boss!" With that, Candace runs towards the open portal and jumps in, much to her Stacy's horror.


"Like that, for instance." said Dr. Baljeet.

"Hey, Candace." said Phineas as his sister landed on the ground.

"Phineas and Ferb, you guys are so… Wait, why are there four of you?" she says quizzically.

"Um, they're from this dimension." replied Phineas.

Just as Candace opens her mouth to ask another question, a portal opens up behind Phineas and Ferb, and Team Avatar gets thrown out. The portal closes immediately afterward.

"That's it, we're taking first-class seats next time!" exclaimed Bolin as he was rubbing his behind.

"Guys, we're here!" exclaimed Korra as she stood up and scanned the underground base.

"Great. More friends of yours, I suppose?" asked Candace-2.

"No, no, we were investigating the presence of numerous portals in our world, then we decided to go inside one and see what it had to offer." calmly explained Mako.

"So you just had to go and choose ours. Just my luck." muttered Candace-2 under her breath.

"Since when did I have a bossy alternate counterpart?" wondered Candace.

"Oh, I'm sorry, where are our manners? My name is Korra and I am the Avatar, master of all four elements! Guys, let's not be rude! Introduce yourselves!"

"I'm Bolin! Nice to meet you all! But seriously, what's up with that triangle headed kid?"

"Hey!" exclaimed Phineas and Candace-2 in unison.

"You do not talk to my little brother like that!"

"Pardon my brother here, he's just like that. The name's Mako. Republic City Police." he says as he showed them his badge.

"I'm Asami Sato. Pleased to meet you!"

Candace-2 was a bit hesitant to introduce herself, but her politeness eventually won over.

"The name's Candace Flynn. Nice to meet you." she said, albeit dryly.

"I'm Candace Flynn too!" shouted Candace from the back.

"Wait a second there, Korra, is it? What did you say you were?" wondered Phineas.

"I'm the Avatar! I'm the master of all four elements!" she said proudly.

"Say what again? Ava-tar? Master of all four elements? What does that mean?" said Phineas, confused again.

"Just watch!" said Korra as she proceeds to bend all four elements in the order of the Avatar cycle.

EARTH!

She raised two large pillars of earth from the ground...

"Whoa! Th-that's awesome!"

FIRE!

…then unleashed a large stream of fire from her right hand…

"Scorching hot!"

AIR!

…and a powerful air blast on the other.

"What a powerful breeze!

WATER!

"That finale was amazing!"

Korra finished her display of skill by propelling herself up into the air with a water spout before freezing it and turning it into a solid platform. Everyone in the room was amazed at her demonstration. Everyone except the two Candaces, that is.

"My head is throbbing in pain right now. I have absolutely no idea what by brothers have done this time." said Candace as she rubbed her forehead.

Candace-2 walked over to her and said, "Don't worry, I feel you, girl." She then pats Candace on the back, just like Ferb had done earlier.

"Now that that's taken care of, let's go and save Perry! Please, other-dimension Candace, will you help us? And you too, Miss Avatar?" begged Phineas.

Korra looked over to her friends. "Well, he really does need our help after all! All right, kid, we'll join you! Oh, and you can just call me Korra."

Candace-2 thought for a moment, and spoke. "Fine, I'm helping you get to Doofenshmirtz' tower. Boys, you stay here. It's far too dangerous for you."

"But, Candace, we want to help them! Do you remember when we lost our Perry?" pleaded Phineas-2.

"No, you're staying here. That is an order. Do you understand?"

"Yes, ma'am…" Phineas-2 sighed, defeated.

"All right everyone, I'll show you the way to the secret tunnels. It's going to lead us straight beneath Doof's tower."

"What kind of a crazy name is Doof? HAHAHAHA!" snorted Korra.

"This is not a joke! You may have yourself some really amazing powers, but you are no match for the evil overlord Dr. Heinz Doofenshmirtz!" snapped back Candace.

"Psh, that's nothing! Six months ago, me and my friends here stopped a revolution by Amon and his Equalists, who threatened to rid our world of bending! And just a week ago, I survived having my Avatar spirit getting separated from my body and I managed to defeat my own uncle Unalaq after he became the Dark Avatar!" Korra said boastfully.

"We can vouch for that!" Bolin shouted from behind.

"Sigh, fine. Enough of your tall stories, if you want to help these two boys, then you are going to have to follow my orders. Understood?" she said right at Korra's face. The Avatar was offended and did not take her tongue-lashing lightly.

"Who died and made you queen, huh? You're not the boss of me!"

"Yeah, that's the spirit!" shouted Buford-2.

"I know I can be bossy, but I've never imagined myself being that bossy!" Candace thought aloud again.

Ferb comes over to try and comfort her, but she refuses.

"That doesn't get you two off the hook, however! I'm still going to bust you!"
