[A/N: Well, the story would be a little same as Avatar: The Last Airbender in the beginning. But that would change in the end. If you've watched the serie, you could already guess what the first chapter is going to be about. Nino would end with someone else, you might already know who. Oh and Alya, Felix and a bunch of other characters would come in this story too.
Okay, I already wanted to make a fanfiction of ML with this AU. Because yeah, why not. And I got even more motivated when I saw a really cool fanart from lily-frog. I based this story on Avatar: The Last Airbender. I hope I will bring some of your (childhood) memories back with this~]

"Water. Earth. Fire. Air. My grandmother used to tell me stories about the old days, a time of peace, when the Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But that all changed when the Fire Nation attacked. Only the Avatar mastered all four elements. Only he could stop the ruthless Firebenders. But, when the world needed him most, he vanished. A hundred years have passed, and the Fire Nation is nearing victory in the war. Five years ago, my parents and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my sister to look after our tribe. Some people believe that the Avatar was never reborn into the Air Nomads and that the cycle is broken, but I haven't lost hope. I still believe that somehow the Avatar will return to save the world."

Two girls were just sitting in a boat, trying to catch some fishes for their village. One has bluebell eyes, and dark blue hair wearing it in two pigtails. The other one has unusual red hair for people from the water tribe. The middle part of her bangs of her hair are black, what makes it even more weird. On the other hand, she got dark blue eyes. When someone would look at those girls, no one would think that they are siblings. The red haired one is the oldest, just three years apart from her seventeen years old little sister. The red haired one looked focused on the water, holding her spear in her hand. She saw the fish and await to catch it. On the other hand, the little sister saw one fish too. She didn't have a spear like her sister does, so she took her right glove off and used waterbending to bring the fish out of water, firstly unsure and afraid that her sister might get mad at her for using waterbending. She smiled when she caught the fish in her own sort of water bubble.

"Tikki, look!"

"Shh, Mari. I'm concentrating. I won't let our dinner escape from us…"

"But Tikki, I caught one!"

"You did what?" She quickly turned around, to see her little sister using waterbending. The fish in some water bubble getting popped when Tikki accidently touched it with her spear. The fish fell in the water and Marinette looked upset at it. Tikki looked at the fish, swimming away from their boat. Tikki was also upset, but not because their dinner was swimming away. She looked at Marinette with a serious look.

"Mari, I told you this before. You can't do that, you can't use waterbending. You can't control yourself, your waterbending is… well, quite unpredictable." Marinette stood up right away, making the boat shake a bit. She looked angry at her older sister and pointed at the water. "But I caught it! I caught the fish with my waterbending!"

Tikki putted her spear down and stood up gently, so she won't shake the boat too much. She put her hands on both of Marinette's shoulders. "Mari, it would be better not to use it will someone would teach you... Unfortunately I'm not a waterbender… And mom is also gone to help the earth kingdom alongside with dad. I don't know how long it would take before they return, but because she's the only waterbender beside you in our tribe, you can't use it. Please be patient, I'm sure they would return soon and mom will teach you waterbending." She smiled gently at Marinette, hoping that she would drop the subject. But she didn't. Instead, she looked angrier and sad, like something snapped inside of her.

"You keep saying that! But this war is already taking like hundred years! What if they don't return? What if someone get hurt and I can't even use waterbending for healing purpose! What if the fire tribe would suddenly go here to attack? I can't do anything with my waterbending how it is now!" Marinette keep screaming, swinging with her arms uncontrollably. She didn't even notice that she has been using waterbending the whole time in her rage, making the iceberg behind her break. Tikki looked at it very surprised and pointed at it. "Marinette…"

"What?! You want to tell me again that I should wait? I will not! It might take forever till our parents finally get home. I want to leave this place! I… I want to see our parents, Tikki! It's been five years, FIVE YEARS! We haven't heard from them since then!"

"Marinette, stop!" Tikki screamed and hold her little sister's arm down. Marinette looked behind her when she heard the sound of breaking ice. She clutched at Tikki's coat, looking with fear in her eyes at the breaking ice, making the boat drift away and bump into another iceberg. Tikki quickly carried Marinette and jumped on an ice floe. Marinette looked at the sinking boat and then back at the place where the big iceberg was. "D-did I… do that? Omg, this is all my fault… I'm so sorry, Tikki. I made our boat sink… How should we even return home now?"

Tikki petted on Marinette's head, hoping it would calm her down. "Calm down, Mari. We aren't around people, so it was still alright for you to use your waterbending just now. But please… be more careful in the future. Don't worry about the boat, I will think of something. We will go home, it will be alright." Marinette nodded and let go of her sister, still looking at the place where the iceberg should be. Suddenly she saw that the water under their ice floe was glowing. She backed away, like her sister does and hugged her sister in terror, as the glowing light is getting out of water. She stared at it for a while, only to see some kind of round iceberg coming out of it. She let go of her sister and walked to the edge of their ice floe, piercing her eyes to the iceberg. She saw something was inside, it looked like… a guy and some sort of big animal behind him. She saw that he got some arrow like signs under his hair and hands. Suddenly his eyes opened and they were glowing, just like his arrows. She doesn't know why it was glowing, but it does seems like the guy is alive.

"Tikki, we have to save him! He's still alive!" She took Tikki's machete and run towards the iceberg, making Tikki to run after her with her spear. "Wait, Mari! We don't know if he's dangerous! Didn't you saw those glowing arrows?" She screamed after her, holding her spear firmly, ready to attack. While Tikki is still jumping on the ice floes to get to her little sister, Marinette was using the machete to break the ice. Just when Tikki stood behind her, a part of the ice broke and some strong air got out of it. It made Marinette get blown away towards Tikki. Tikki stood strongly on her feet and hold her sister with one arm, while holding the other arm in front of her face so it would block the wind. The wind calmed down and they looked up at the big iceberg breaking into half. More air came out and suddenly even some big light came out of it, glowing up towards the sky. They closed their eyes, in order not to go blind.

They weren't the only ones who saw the light. On a big dark ship stood a guy around his eighteens wearing clothes of the fire nation, looking at the light. His blond hair waving because of the suddenly strong wind. He turned around to face a guy around his late twenties, with black hair and lighter green eyes than the blond one.

"Plagg! Did you see that? You know what this means right?"

He smiled happily at the guy called Plagg. Plagg looked up from his table, where there lies cheeses. "I won't get to enjoy my cheese?" The blond guy turned around, too look at the light again, disappearing from the sky. "It means mine search. It's about to come to an end. I can finally be able to meet the Avatar after all those years of searching." He looked dreamy at the direction of where the light came from. Plagg only sighed and shrugged his shoulders. "Prince Adrien, it was just some light. Sorry to break your dreams kid, but it doesn't mean that it would be the Avatar. We've been searching for many years now and just because you saw some powerful light, doesn't mean it's the Avatar. I don't want you to get too excited over nothing, so calm down. Come, sit down. How about eating some Camembert?"

Adrien looked at his young uncle and sighed. "Plagg… I don't want to stink like cheese when I will meet the Avatar, so no thank you." He looked up and pointed at the direction of the light. "Helmsman, head a course for the light!" Plagg stared at the direction of the light with a serious look on his face. He looked at his Camembert and took a bite of it, still with a serious expression on his face.

"Sabrina, did you see that!"

The girl with honey blond hair pulled back into a ponytail and has light blue eyes looked at her sort of slave, well, she could call her that because she does everything for her. Her slave got shoulder-length orange hair and sea green eyes. Not really attractive girl is she would say so. Both of them were wearing clothes of the fire nation and of course the ship they're standing on are the same as the one of prince Adrien. However, they were still apart from each other, not knowing that they are closer to each other than they thought.

"Finally, finally a sign of the Avatar! If we catch him and bring him to Adrien's father, the Fire Lord, he will surely make me marry him!" She giggled and already imaged how the marriage would go. Sabrina just nodded and after a while of thinking, she realized something. "Chloé, you do get a choice right? I mean, mostly people would offer their oldest son for marriage. And prince Felix is the oldest even if he's just some minutes older than prince Adrien…"

Chloé glared at Sabrina, what made her apologize quickly. "You know who are talking to right! I'm the daughter of the great admiral! Of course I have a choice! The Fire Lord will listen to my requests if I catch the avatar and Adrien will be mine~" She laughed loud and ordered her helmsman to head to the light.

Tikki hold Marinette against her, to protect her from the strong wind getting out of the broken iceberg. They looked up when the wind calmed down and saw the guy with arrows coming out it. He stood at the edge of it, looking really threatening with those glowing eyes and arrows. So threatening that Tikki pointed her spear towards him. "Don't move!"

The light on his eyes and arrows slowly disappeared and turned normal again. His eyes closed and his legs are going weak, what makes him fall down. Marinette quickly let go of Tikki and run forward to catch him just in time. Tikki kneeled down on one knee and looked at the guy. He looks like someone around their age, maybe a bit older than Marinette? He has some dark skin; his clothes seems to be more thinner and it was total different color then theirs. Their clothes were blue, his was more like dark yellow and dark orange. Not to mention he got some weird arrows under his short dark brown hair and on his hands. Slowly his eyes opened and Tikki saw that he got some beautiful golden brown eyes.

The stranger looked in Marinette's eyes, being quite bewildered by her looks for a moment. Marinette smiled at happy, feeling relieved that he's still alive. The guy actually didn't really understand what was going on and why he suddenly saw a cute girl in front of him, but he didn't dislike it. "Hey… I need to ask you something." He said weakly, feeling like he didn't used his voice in years. Marinette looked questionable at him, wondering what he wants to know. "Please… Come closer," the guy asked. "What is it?" Marinette asked, getting closer to him, still wondering what he wants.

His half closed eyes turned into just totally open eyes and he smiled happily at her. He told her what he wanted to tell her in a clear, happy and also hopeful tone. "Would you go penguin sledding with me?" That took Marinette and Tikki by surprise, they looked dumbfounded at the guy they found. Marinette glanced at Tikki and then looked at the guy with an awkwardly look on her face. "Eh, sure…I-I guess?" The guy looked happy and elegantly rises to his feet in one swift motion, not noticing that he surprised the two. Unlike Marinette who looked at him in awe, Tikki stood up right away and backs away in more like a shock and feeling threatened. She pointed her spear at him, making herself stand defensive. The guy just looked around and rubbed his head, wondering what was actually going on. "What is going on here?"

Tikki looked a bit annoyed and serious at him. "That's what I want to ask. How did you even end up here and in that ice?" "I'm… not sure either… Also could you please don't point at me with that spear, young lady." Tikki wanted to say something, but got interrupted by some loud groan, coming from within the crater of the iceberg. The guy quickly turned towards the iceberg, scrambles up the ridge of the ice and happily jumps on the head of a large, furry creature that has the same arrow-shaped marking on his forehead as the guy.

"Wayzz!" He exclaimed happily to see his friend. "Are you alright?" He asked, checking on his eye and poking him a bit. "Hey, wake up buddy." The bison didn't seem to move or open his eyes at all. He got worried and jumped in front of his mouth. Wanting to move his head up, but end up lifting his upper lip up with some struggle.

Marinette and Tikki got curious what was going on so they walked around corner, only to see the strange guy lifting the lip of some weird large creature. They were totally lost at words and looked at it with wide eyes and dropped jaws. After that they also saw that that big animal suddenly moved again and used his giant tongue, it was really huge, to lift the guy up. Tikki and Marinette got closer, Tikki still holding her spear firmly for defense. "What is that thing?"

The guy looked at the two ladies and smiled, while petting his bison. "How rude, it's not a thing. This is Wayzz, my flying bison." Tikki looked at the bison and then back at the guy, looking at him as if he was joking or he was just crazy. "Right. And this is Marinette, my flying little sister." She pointed at Marinette and said it with sarcasm in her tone. Marinette shoots her an odd look and while the guy looked questionable at the red haired lady. He then looked cheerfully around and smiled at them. "So… do you guys live around here?"

Tikki got suspicious about that and pointed her spear accusingly at the very suspicious guy again, what made him look surprised at it. "Why do you want to know? We will don't know you. Mari, be careful. Did you see that crazy bolt of light? He might be signaling the Fire Navy. What if they were around here and saw that light, they would come here right away! We will be in danger because of him."

Marinette pushed her spear away and addressed to her sarcastically. "Oh yeah, I'm sure he's a spy for the Fire Navy. You can tell by that evil look in his eye." The guy stared at them for a bit, but then shoots the two an earnest grin. Marinette walked closer to him and pointed at Tikki. "Sorry about that. The extremely worried one is my big sister, Tikki. What's your name actually? You didn't tell us your name before."

"Oh, you two are sisters? Cool man. Oh, I'm N...Niha-a-a-a-achoo!" The guy sneezed, creating an air blast that sends him soaring into the air. He lands quickly on the ground, unharmed at all. "Sorry about that. I'm Nino." He sniffled a bit and smiled at them.

Tikki looked with total disbelief at the guy called Nino. She checked his clothes and those arrows again. "So you're an airbender." She sighed and rubbed at the back of her head. "Giant light beams, flying bison, airbenders… This day couldn't get even more crazier. Let's go home." She turned around, wanting to leave but only got reminded that they got stuck, being stranded in the middle of the ocean with no way home.

"Well, if you guys are stuck, Wayzz and I can give you a lift." He smiled at them, airbends himself onto Wayzz as if he's ready to go. Tikki looked at Nino and sighed, apologizing for her behavior before. "Sorry about before and thanks for the offer." She walked to the bison and climbed on top of it. She looked down at her little sister with a questionable look. "You're coming, sis?" Marinette looked up, holding her hands clenched together. Tikki sighed a bit and hold out her hand, smiling at her. "Don't be afraid, I'm here. Come on." As Marinette hesitantly hold out her hand, Tikki reached her hand out and grabbed Marinette's. She pulled her up and smiled at her. "Not so scary right?" Marinette nodded and sat next to her.

"Okay, first time flyers, hold on tight! Wayzz, yip-yip!" The big bison made a loud noise, before moving his tail up and then down. Marinette and Tikki expecting to fly, but only landed into the water. They looked around and Tikki leaned forward, looking at Nino. "Well, that was quite a flight. I thought you said that he could fly." Nino petted on the head of his fluffy bison and looked at Tikki with a confident smile. "Wayzz's just a little tired. A little rest and he'll be soaring through the sky. You'll see~"

"I'm going to bed now." Plagg said as he was yawning and stretching his arms. "Yep, men needs some rest even if they're still young." He stared at the back of Adrien, still not getting any responds. After a short pause, he abandoned his try at a veiled suggestion and delivers his request more clearly, but his tone sounded tired. "Prince Adrien, you need some sleep. Even if you're right and the Avatar is alive, will you really find him? I mean, many had tried before like your father, grandfather and great-grandfather but they all failed. Don't get too excited and just take some rest." Adrien looked away and still gazed at the water. "I'm sure I will find him, Plagg. I will go to bed soon. It's just… finally able to meet the great avatar makes me not wanting to sleep at all. I want to ask his help and also proof that I'm also here. That father would finally see me, pay attention to me like how he does with Felix. This is the only way for me to show that I'm really his son."

Nino lies lazily on his back, his arms tucked under his head. He saw that Marinette crawls to the front, while Tikki was sleeping. She leans on the front of the saddle and rests her head on her arm. "Hey," she said as she looked at the guy who was firstly only looking at the sky but now at her.

"Hey. Not sleeping yet, LB?"

She looked dumbfounded at the nickname and tilted her head on the side. "LB?" Nino chuckled and pointed at his earlobe. "Saw your ladybug-like earrings. They're cute by the way. But yeah, though it would be fun to call you by a nickname, if you're alright with it." She didn't dislike the idea and also chuckled about it. She never got a nickname besides 'Mari', she didn't mind him calling her LB.

"I'm alright with it. Besides, just wondering… You're an airbender and all right? So does that mean that you know what happened to the Avatar? He was also an airbender right?" He didn't expect that question and smiled a bit weakly at her. "Oh, no. I don't know him. I mean, I knew people that knew him, but I didn't. Sorry." Marinette slants her eyes in disappointment for a second, but then smiled again at Nino. "It's alright. Was just curious. Good night, Nino."

"Sleep tight." He smiled at her till she got back in the saddle. He uncomfortably turns around, lying on his side with a look of guilt crossing his face. He was telling a lie to someone he just met and that was not a good sign.

[A/N: If you wonder how Tikki looks like, I imagined her looking like this but then in water tribe clothes and little dark skin, like Katara. The same goes with Plagg, I also think of him with this style. But then with beige skin color. . ]I imagined Marinette and Adrien looking like this fanart from the amazing lily-frog. post/143594168474/ml-benders-au-this-is-based-on-their-super Oh and if you wonder why Nino is the avatar and not someone like Marinette. I got convinced by thelastpilot's fanfics about Nino, Nino seems like a wise person. But also someone like Aang, still quite a child. (Well, Aang was a child, but never mind that. xD) ]
