Author's note: this is a story idea I had for a where Voltron Legendary Defender and Avater the last Airbender have a crossover, I I got this idea from Voltron Frozen Defender.

Also just a heads up, this is a alternate universe, and in the alternate universe Shiro is not gay. And there will be changes that I added, like Lance love interest.

So let's start this story.

Disclaimer: I do not own anything Avatar the last Airbender or Voltron Legendary Defender, they are owned by their respective creators.


Chapter 1: Accidentally In another dimension.


Two lights were seen clashing, one blue, one purple, if seen closer you can see that it's two giant robot like beings fighting.

The first giant robot was comprised of the five lions. Red and Green were the arms, Yellow and Blue the legs and Black was the head and body. On it's chest stood a glowing neon blue arrow shaped symbol. While having what look like red wings on it's back and a light blue sword in it's right hand.

This is none other then Voltron, the Defender of the universe, first formed 10,000 years ago to protect the galaxy from evil. A mighty warrior standing at over 100 meters tall and assembled fromfive robot Lions. The lions are linked with the souls of their chosen Pilots.

These pilots are called Paladins. Paladins are given a special device known as a Bayardsthat allows them to unlock special abilities through their Lion for Voltron to wield. The Lions and Paladins are usually color-coded to match each other. When formed as Voltron, the Paladins pilot the giant robot in unison.

And their Paladins are, Takashi Shirogane, Keith, Pidge, Lance and Hunk.

The second giant robot looked like it had dark red armor on it, purple glowing lights on it, and eight blade looking wings on it's back as they glowed a light purple color.

It is a Mechsuit Armor.

This Mechsuit Armor was developed by Haggar sometime following Team Voltron's escape from Galra Central Command ship.

And it's piloted by the emperor and leader of the Galra Empire, Zarkon, as it looked exactly like him in some way.

The two robot's clashed within the Emptiness of space, as voltron shot Lazers like blasters out of his hands at zarkon as zarkon all the Blaster fire.

As zarkon charges towards Voltron as it summoned me dark purple like sword using the stolen black lion bayard as he blocks the Lazer and kept charging towards voltron.

As zarkon was now close to voltron, he slashed his sword towards voltron, while Voltron did the same with his sword, as both swords collided into each other, it created a Shockwave as both giant machines try to push each other back.

"This is my time to reclaim the Black Lion. Nothing can stop me." Said Zarkon as his eyes glowed purple as he attempted to gain control of the black lion.

Meanwhile, Shiro could feel zarkon trying to take control. "He's trying to control my lion. I can feel him in my mind." He says as he was struggling to keep control. "Fight it, Shiro!" Said Keith.

Zarkon took this as an opportunity to force voltron back before he stopped, then voltron charges towards using his jet boosters to fly straight at zarkon as voltron then cocked back his arm, ready to stab it into Mechsuit Armor that zarkon is using as the Paladins yelled a battle cry as Voltron thrust due to his sword straight towards zarkon, only for zarkon to use the arm of the Mechsuit Armor to Direct voltron's sword away by having it stab into it.

Zarkon then took this opportunity to Lunge the right arm of the Mechsuit Armor at voltron as an purple bladed whip pushed Voltron back as the bladed whip wrapped around voltron's neck sending a electrical surge through Voltron the electrocuting him as the sounds of the five Paladins screaming could be heard within voltron.

This lod to voltron disassembling back into the five lions. As the five Lions floated in the gravityless space offline, Zarkon called back his bladed whip as he look down on the Paladins.

"You should have fled like your predecessors. Now, the time of the Voltron Paladins, is finished." Zarkon says and Triumph.

The red, blue, green and yellow lions came back online, they looked directly towards the black lion, as it hasn't yet came back online. "Shiro?" Keith said to get his friends attention but no response. "SHIRO!" Shouted Keith only for no response, as shiro was unconscious within the black lion.

"Something's wrong with Shiro." Keith said. "Guys, we can't let Zarkon get the Black Lion." He says to Pidge Lance and Hunk as the red blue yellow and green lions get into battle ready stands as they stand ready to protect the black lion from zarkon.

Seeing this, Zarkon only got his bladed whip ready as he then charges towards the four lions ready to take back the black lion.

"Keep zarkon away from the Black Lion!" Said Pidge.

At hering a familiar voice, Shiro started to wake up.

"Come on! We can't give up!" Said Keith.

At hering keith's voice he started to try to wake up.

"I'm running out of strength man." Said Hunk

After waking up fully, he looked to see what was going on.

"Look out!" Said Lance as he then got hit by zarkon, then Pidge tried to hit zarkon with a Lazer blast from the Canon on the green lines back, but it failed on zarkon used his blade like wings to stop the laser dead in its tracks.

Shiro saw this and felt like there was nothing he could do. However the place where the Bayard goes into opens up as Shiro then knows what he must do.

Zarkon then attacked the red lion with it's bladed whip, as zarkon blocks a charging attack from the yellow lion.

Shiro then started to charge at zarkon with the black lion while he was as he was fighting off the other lions. Seeing Shiro coming at him he prepared himself for whatever he had planned.

As Shiro was charging towards Zarkon, he started to remember all the times he's connected with the black lion as he started to truly connect with his lion. At that moment both Shiro and the Black Lions eyes glowed at the same time, and in that moment the black lions red wings of sort glowed a light blue color as they then transform into bigger versions of its wings with blue like blades on it as the black lion roared.

Zarkon couldn't react in time, in a blue flash of light the black lion flew right past Zarkon, and in that very instant, within the room that connects a Paladin's mind with their lion Shiro took the Black Lions Bayard from zarkon as it disappeared in a flash of purple out of zarkon's hands as zarkon was shocked at what just happened. After that, the wings on the black lion returned back to normal.

"Whoa... What did you do?" Asked Lance as he was confused on what just happened.

"I got Zarkon's bayard." Says Shiro sounding surprised. "You mean you've got your Bayard." Said Keith with a smirk as the black lions bayard transformed back to how it used to be. Shiro then got a serious face on.

"We've only got a few minutes left before power returns to Zarkon's ship. FORM VOLTRON!" Shiro declared.

The black lion let out an almighty roar as it and the other lions began disassembling and reassembling as component parts for something forming feet and legs followed by arms and a body five were becoming one, retracting and combing into Voltron once again.

The Paladins of Voltron stared down Zarkon within his Mechsuit Armor as they were ready to finish this once and for all.

"Hello, paladins!" Said a all to familiar voice over the comms, it was Coran. "Yeah!" Shouted all five of them in unison. "You're alive!" Said Hunk with tears of joy.

"Is everyone okay?" Asked Shiro through the comms. "Yeah, I'm fine! Don't worry, guys!" Said Slav through the comms which made Lance sign. "Oh, great. Slav made it." He says in sarcasm.

With that, voltron charge towards zarkon as both giant robots clash blades as they both created a Shockwave from their clash.

They kept clashing their respected blades, not giving their opponents a opening.

As this was happening, zarkon's fleet and drones along with his ship was slowly regaining its power.

"The power on Zarkon's ship is returning! We need to get out of here! I'm going to get Allura!" Said Coran.

Voltron and Zarkon charge at each other as their blades clash as as two rings of blue and purple formed after their clash. As both giant robots flew back a distance Voltron and Zarkon at high speed change at each other once again.

Voltron prepared to Lunge it's sword at zarkon's Mechsuit Armor. "This is are last chance! Let's finish this!" Said Shiro to the other Paladins as he, Lance, Hunk, Pidge and Keith all reels back there controllers as all five Paladins shot one arm forward as they charge directly towards Zarkon with a loud battle cry.

As both Voltron and Zarkon we're almost in close proximity of one another, a white flash of Lights appeared, once it died down it revealed voltron's blue sword stabbing directly into the side of zarkon's Mechsuit Armor.

Seeing this, zarkon refuse to lose to the Paladins of Voltron, he lunged the arms of his Mechsuit Armor as he grabbed the head of voltron and send a purple shock of electricity through Voltron as he attempted to regain control of the black lion once more.

Seeing the place where they put the Bayards at, he grabbed his bayard and immediately cocked back his arm it was all the force you can muster slammed his bayard into it and rotated to the right having his bayard face sideways, as the inside of his controls of the black lion glowed purple, as the sort of Voltron then engulfed into fire.

Keith then stab the sword deeper into zarkon's Mechsuit Armor as it started to Short Circuit. And with a loud roar from the five Paladins, move the sword that was stabbed into the Mechsuit Armor upward cutting the upper part of the body and have which caused a bright purple light to form from where they stabbed it at.

"AAAAAAAAAHHH!" Screamed zarkon as he was being engulfed within the surge of power. However as zarkon's Mechsuit Armor is about to explode alarms started to go off within voltron.

"Uh, guys, what's going on?" Asked Hunk in a scared tone.

"The alarms are going off but why?" Questioned Lance.

"It's from Zarkon's Mechsuit!" Answered Keith.

"It's about to blow up in a very big way!" Says Pidge in a panic tone.

"We need to get out of here, NOW!" Yelled Shiro as he grabbed the controllers of Voltron and quickly started to get Voltron out of the way of the explosion. And in that moment, the Mechsuit Armor exploded. "I don't think we will make it." Said Hunk.

"No, no, no, no, NO!" Said Lance in a panicked tone as the explosion started to get closer and closer to them. "What should we do?" Asked Keith sounding worried himself.

"Brace for impact!" Said Shiro. Everyone braced themselves for the impact, hoping they'd survive it.

It then exploded creating a bright light that engulfed Voltron.

Everyone's vision from the castle of lions went white for a few seconds, but once it died down, they they saw that Voltron was gone.

"What!" Said Allura sounding shocked and confused.

"What just happened?" Asked Coran as he tried to look at the monitors.

"They were caught in the explosion, however there is no Voltron or lions, they are, just, gone." Allura says with widened eyes.

"Gone? You mean, like...dead?" Coran asked as his eyes widened in horror. "There not, I can still feel my connection to the five lions." She tells him.

"But where are they then? If they're not dead, then where could they have gone?" Asked Coran, still very worried for the Paladins.

(Elsewhere in another Dimension).

High in the skies, Appa the Sky Bison, and the fateful companion of the Avatar soared above the landscape. At the reins was none other than Avatar Aang; sitting behind him in the large saddle we're his friends Katara, Toph, and Sokka.

"How long have we been flying on this thing? Can we please set down? I hate not being able to see." Toph complained.

"It's a lot faster this way than just walking Toph." Sokka told her.

"Hey, I'm still new to your little group, remember? I'm not quite used to flying." Toph replied.

"You'll get used to it eventually Toph." Katara said, trying to reassure her.

"So, guys. Anyone got an idea of where to go to next?" Aang asked.

However, before anyone can answer; they noticed something in the sky. they saw five fire balls of sorts in colours of violet, red, green, blue, and yellow.

They all looked up, surprised by the sight of the fireballs. "What in the world are those?" Sokka asked, pointing at the fireballs.

High above, the fireballs are actually the Voltron Lions crashing down from the sky. Inside the powerless Black Lion, Shiro who is trying to guide his lion into a controlled crash, and inside the other four lions Kieth, Lance, Hunk and Pidge are doing the best they can guide their lions into a controlled crash.

"Come on come on!" Kieth growls trying to pull his lion out of the crash. "Yellow come on work for me!" Hunk tried. "Come on Blue anytime now!" Lance panicked. Pidge looked outside and saw they were drawing ever closer to the ground. "Theres no time!" She cried. "EVERYONE BRACE YOURSELVES!" Shiro shouted.

As they braced themselves for the crash and the ground drawing ever closer Lance could only say one thing. "Oh Quiznak!"

The Lions crashed to the ground knocking down trees and leaving a trail of drag marks behind them sliding on the ground, building up a mound of dirt and rocks in front of them eventually bringing them to a halt. Steam poured from the lions as they cooled down.

Aang was forced to stop his bison in the air, causing it to hover as they look to where the fireballs crashed. "What the heck was that?!" Sokka exclaimed.

"What? What was what?" Toph questioned. "Five colorful fireballs just fell out of the sky, that's what." Katara answered. "Any idea what that was Aang?"

Aang shrugged his shoulders, just as confused as everyone else. "No idea, I've never seen anything like that before."

"What does this mean?" Questioned Sokka.

"No idea." The Avatar answered as he looked at where the five colorful fireballs crashed at. "But I'm gonna find out." He pulled on the reins and Appa began his descent towards the forest below.

(With the Paladins).

Everyone slowly started to come to their senses and started to get out of their respective lions. "Is everyone alright?" Asked Shiro, checking on the other Paladins.

Everyone slowly came to and looked around, taking in their surroundings. They were all in a forest, surrounded by trees and undergrowth. They looked to be in the middle of nowhere.

"I'm fine." Keith said, rubbing his head. "A little banged up, but otherwise okay."

Hunk slowly got out of his lion, he looked a bit shaken up but he was okay, and then he puked. "Same here." Said Lance, he looked a little bruised, but he was alright. Pidge came out of her lion, she looked pretty scratched up, but she was alive.

"I think I might have a few broken bones..." She said as she held her right arm.

Shiro rushed over to Pidge, concerned for her injuries. "Are you sure? Can you move your arm?" He asked, gently taking her arm and examining it.

Pidge winced in pain as Shiro touched her arm, but she nodded. "Y-yeah, I think so." She said, trying to move her arm, but she stopped when she felt a sharp pain in her shoulder. "Ow!"

Shiro quickly stopped her from moving her arm further, not wanting to cause her any more pain. "Don't move it too much. We need to get you back to the castle of lions." He said.

Pidge nodded, trying to hold back tears from the pain. "O-okay..." She said quietly, leaning against her lion for support.

Keith, Lance, and Hunk approached Pidge and Shiro, looking concerned for their teammate.

"Allura, we need you and Coran to hurry and get the castle of lions down here, Pidge is hurt." He says but no response, only static.

The other paladins looked at each other, worried. "What's going on? Why aren't they responding?" Lance asked.

"I don't know." Said Shiro, looking worried. He tried to contact them again but still no response. "It's like the comms are jammed or something."

"This isn't good. We're stuck out here and Pidge is hurt. What are we gonna do?" Hunk asked, starting to panic.

"Calm down Hunk, panicking isn't going to help us right now." Said Keith, trying to calm Hunk down. "We need to figure out where we are first and then try to contact the castle of lions again."

"Uh, guys, I don't remember there being a planet here when we we're fighting Zarkon and his Fleet?" Said Lance.

The other Paladins looked around, taking in their surroundings once more. The trees were unfamiliar, and the landscape was completely different from any planet they'd been on before. "You're right, this isn't any planet we've been to." Said Shiro, looking around as well.

Keith looked around, trying to figure out where they were. "You're right, this is completely different." He said, looking around them.

The forest they were in seemed completely familiar, with trees and plants that they have seen before. The sky was a bright blue, with fluffy white clouds floating overhead.

Hunk looked up at the sky, feeling a sense of unease. "This doesn't look like any planet we've been to, but it also doesn't look like anything dangerous." He said.

"Yeah, it kinda looks like earth." Says Keith.

Lance raised an eyebrow at Keith's statement. "You're right, it does look like earth." He said, looking around at the trees and the terrain.

"But how did we get here? We were fighting Zarkon, and then...BOOM! We crashed. And now we're stuck here with no idea where we are or how to get back?" Asked Hunk.

Shiro sighed, rubbing his temples in frustration. "I don't know, Hunk. But we need to stay calm and figure out a way to get out of here." He said, trying to remain level-headed. "First, we need to find shelter and try to get Pidge some medical attention."

"Did you guys hear that? I think I heard voices?" The Paladins turned to the sound of that voice towards the sound of leaves rustling in the woods near them.

The paladins looked towards the sound of the rustling leaves, tensing up and preparing for a fight. "Stay alert, it could be Zarkon's forces." Keith said, readying his bayard.

The Paladins then looked to see four kids walk out into the clearing only for three of them to stop with wide eyes as they saw the armored people standing before them. There was a brief moment of awkward silence between the two groups, which one of the kids seemed to pick up.

"Uh, guys? What are we looking at?" Toph asked. "Oh nothing." Katara began. "Just a bunch of guys in weird armor."

"Oh." Said Toph.

Sokka then saw Keith and quickly pulled out his boomerang and pointed it to the Paladins. "It's the Fire Nation!" He says, much to the confusion of the paladins.

The Paladins all looked at Sokka with confusion and bewilderment. "Fire Nation? What are you talking about?" Asked Lance, raising an eyebrow at Sokka's accusation.

Sokka didn't lower his boomerang, still eyeing the paladins suspiciously. "Don't play dumb with me! You're all Fire Nation soldiers."

Shiro held up his hands in a calming gesture. "We're not this Fire Nation your talking about, and we're not soldiers." He said, trying to defuse the situation.

Sokka narrowed his eyes at Shiro, not believing him for a second. "Who are you guys?!" Sokka demanded. "Whoa, Sokka hold on. We don't know anything about them." Katara tried. "I don't care! You don't see random people in odd armor, and plus look at that one." Sokka said pointing a Keith. "He's wearing red armor, that just screams Fire Nation."

Keith eye twisted at Sokka's comment. "I'm not from this stupid Fire Nation!" He says sounding irritated.

"Seriously, just because we are out of the ordinary that you don't see every day, doesn't mean we're evil or something?" Lance questioned. "And this coming from a wimpy guy with a pony tail."

Sokka looked offended at Lance's comment. "I am not wimpy! I'm a warrior!" He said, puffing out his chest in an attempt to look tougher. "And just so you know, this is a warrior'swolf tail! Very manly!" Sokka exclaimed with a high pitch voice.

Lance chuckled at Sokka's attempt to look tough, but then quickly covered it up with a cough. "Right, sure. Very manly." He said, trying to hold back a laugh. "Just about as manly as that girly voice of yours." He cracked, earning a glare from Sokka.

"Shut up! My voice is not girly!" He yelled, trying to defend himself.

"I like this guy already." Toph whispered to herself. Before anyone else could say anything, Pidge groaned again in pain as Shiro continued to try and support her and hold her arm. "Lance, we don't have time for this we need to get Pidge some medical attention."

Aang noticed the green armored one was holding her arm. "One of them is hurt!"

Shiro then stood up. "Listen, we don't mean you kids any harm. Our friend is hurt and she needs medical attention." He Said. "Like seriously, you guys know a doctor or something we can take her to?" Hunk asked.

Aang and Katara looked to each other with worry. "Maybe I can help." Katara said as she walked forward but Sokka held his arm out in front. "No, it's a trick! It's gotta be." He said.

"Sokka!" Katara scolded.

"What?! We just find five armored guys, and one of them just happens to be hurt? I'm not buying it, plus for all we know, that one is a Fire Nation soldier." Sokka says pointing at Keith again.

Keith was starting to get annoyed by Sokka's accusations. "For the last time, I am not a Fire Nation soldier!" He yelled. "And if you don't let her help my friend I'll kick your ass."

"Keith calm down." Said Shiro.

"Is that a threat?!" Sokka questioned. Keith took a step forward, his hand on the hilt of his bayard. "You're damn right it is."

Shiro was about to step in and stop them before they hurt each other, but Aang quickly stepped between the two before anything could start. "Sokka, no! We gotta help them."

Sokka looked at Aang, still wary of the paladins. "Why?! That one in red just threatened me! And what if they're lying? What if they're Fire Nation spies?"

"You threatenedhimfirst." Toph corrected. "And for the record, they're telling the truth."

"How do you know that?" He asked.

"When people, lie there's a physical reaction, I can sense that. And their not lying." Toph explained. "Sokka, let me help him. He's hurt, what kind of people would we be if we don't help?" Katara told him.

Sokka looked at Pidge, then at the paladins, and finally back at Katara he then sighed as he was forced to concede. "Fine."

Shiro then lowered the injured Pidge onto the ground and set her back onto a large rock to prop her up. Katara kneeled down and looked to Pidge arm which she can see is broken. "Can you help her?" Asked Shiro.

Katara looked at the broken arm and nodded. "Yes, I can heal her. I just need a second."

She opened the cap on her satchel and began to pull some water out, much to the surprise of Shiro, Keith, Pidge, Lance and Hunk as Katara then bent the water around her hands in the form of a blob and placed it over Pidge broken arm, which began to glow a little bit.

The Paladins watched in amazement as the water glowed around Pidge's arm, the pain in her arm slowly fading away.

After a few moments, the water stopped glowing and Katara removed her hands from Pidge's arm, which was now completely healed.

"Wow cool." Pidge said inspecting her arm. "Thanks." She says as she was getting up.

Katara smiled, glad that she was able to help. "No problem. Just try to be more careful next time."

Then the other Paladins approach Pidge. "How's your arm Pidge?" Asked Shiro.

Pidge flexed her arm a bit, testing it out. "It feels great. No pain at all. That was some amazing ues of quintessence."

"Uh, what is Quintessence?" Asked Aang.

Pidge looked at Aang with a raised eyebrow. "Quintessence? You don't know what quintessence is?"

"You know, quintessence, this blue stuff that every living thing have." Said Lance to the four.

Aang looked confused, as did the other three. "We've never heard of quintessence before." Said Katara.

"Yeah what are you talking about?" Sokka said as he looks behind the Paladins and just now saw the five giant metal lions in different colors as he went wide eyed.

"AAAAAAHH!" Giant monsters!" He says pointing at the five voltron lines. Aang and Katara minus Toph since she's blind also turned to look at the giant metal lions, their eyes widening in shock and surprise.

"Whoa, what are those things?" Aang asked, looking up at the lions with a mixture of curiosity and awe.

"Seriously, you guys have never heard or even seen the five Lions of Voltron?" Asked Lance.

The four of them shook their heads, still in shock at the sight of the giant lions. "No, we haven't. What are they? And what's Voltron?" Aang asked, his curiosity growing even more.

"Also, who even are you guys?" Toph asked the five Paladins.

The paladins looked at each other before Shiro stepped forward. "We were going to ask the same thing to you four."

Little did any of them know, that this meeting between the Paladins of Voltron and the Avatar and his friends, will change the course of both universes forever.

To Be Continued.
