So basically everything from ATLA never happened, Zuko never became good and Zuko's history with his father is a bit different. I've always changed the ages to fit a bit better.

Katara – 17

Zuko- 18

Sokka – 18

Aang- 16

Katara walked through the metal ship, dimly lit by torches on the walls. It was so dark and foreign. Katara was used to light, open places, usually consisting of snow and low temperatures. The guards holding her arm had a tight grip, almost enough to bruise. Good. They should be wary around her. She went easily when they threatened Sokka and Suki but now that it was just her, she wouldn't give in to any of them.

Especially not Fire Lord Zuko.

She couldn't believe that the Fire Lord had come to Kyoshi Island. He wasn't known to leave the palace, ever. Zuko had been the Fire Lord for two years and was known by many things. He was evil, more ruthless then his Father ever was. In fact Zuko had been the one to kill his father. Zuko had challenged his father to an Agni Kai and when the final blow was delivered, Ozai fell and never got back up. Soon enough Zuko's sister Azula disappeared and there were endless rumours on what had happened to her. Some say she had been killed in her sleep and the body had been burned; others said that she was still alive but locked away in a deep dungeon. The only known member of Zuko's family that was alive was Iroh. He was the infamous Dragon of the West and the only person that Zuko ever answered to. Katara had witnessed that first hand.

The thought of being near Fire Lord Zuko did scare her. She hated to admit it but it was the truth. He was the youngest Fire Lord in history but even so no one ever challenged him or even considered trying to de throne-him. Zuko was known for being so cruel and if he really was more ruthless then his father her been then she would have to watch how she spoke and acted around him. When he had stood behind her on the beach of Kyoshi Island, his had been the only steady heartbeat. It terrified her that he had been that calm. No one should ever be that calm in the middle of a battle. Clearly he thought that he had been in control. And now that Katara thought back on it, he had been. The Firebenders outnumbered the rebels and Zuko had control of all of the Firebenders. At a single word from him, they had all stopped!

The Firebenders pulled her into a room, shoving her forwards. It was large and well-lit with the Fire Nation insignia up on the wall. The insignia scared her. That was the signal of the people that her people fought against. Anyone that wore that symbol was an enemy.

Katara turned around quickly, not wanting her back to any of the soldiers. She was on high alert, her own heartbeat loud in her ears. Standing at the door were the two guards that had taken her through the ship. They may have been watching her but she wasn't sure. The masks were scary and she couldn't tell what they were looking at. But she could hear their heartbeats. It was a perk of being a Bloodbender. Their heartbeats were currently fast and she could tell why. They moved aside and in walked the person that she had been dreading. Zuko.

"You may leave now" he said and his voice reminded her of the sword that had been held to her throat. The two guards walked away and Zuko shut the door.

His heart was calm once again.

"Was he lying? The chief. About the Avatar?" he asked.

"No he wasn't. He has more honour then to lie to you" Katara replied, looking down at the floor.

"Are you trying to insinuate something?" asked Zuko calmly.

"Of course not, Fire Lord Zuko" she hissed. So much for watching how she spoke and acted around him. He was so much younger then she had thought, and up close he seemed even younger.

He took a step forward.

"My Uncle seems to think that it is a good idea to keep you here. I, on the other hand, think that you should be exterminated. Like the rest of your kind" Zuko said bitterly.

"Then why haven't you killed me? If I should just be exterminated like some bug then why didn't you just kill me on the beach?" Katara said resentfully finally looking up at him. She noticed a large scar on his face, but focused only on his eyes. They were golden and looking right at her.

"Did you not hear me? I am listening to my Uncle. I don't know how your people treat their elders, but I respect mine."

She couldn't help but stand up a bit straighter. Katara could take any insults to herself from him, but she wouldn't accept any insults made about her people. The Fire Nation made them out to be barbarians because they differed in their ways of life but it wasn't true. The Water Tribes were just as refined and cultured.

"My people treat their elders with the respect and dignity that they deserve. And clearly you do not treat all of your elders with respect" Katara uttered and instantly regretted it.

"What do you mean by that Waterbender?"

She'd already started the insult. Might as well finish it. He was going to end up killing her eventually anyway.

"Didn't you murder your own father? Not very respectful-"

He stormed over to her and his hand was around her throat, pushing her into the wall. She was off of the ground, being held up by the neck.

"If I murdered my own father Waterbender, then what makes you think I'll have any problem with snapping your neck right now?" he spat.

"She is an important person nephew. Let her down" a voice from behind Zuko said.

Katara hadn't even heard the door open. The hand disappeared from around her neck and her feet landed back on the ground. Katara coughed slightly before trying to straighten up. She would not seem weak in front of any of them. Zuko glanced at her, giving a once over and then turned around.

"What do you mean?" Zuko asked. Katara pressed herself against the wall, listening in. She knew exactly what General Iroh meant, and was surprised that Zuko didn't. Did he not have soldiers that gave him the information on the leaders of the Water Tribe and Earth Kingdom? She had been the Chiefs daughter and now she was the Chiefs sister. That would have come up at some point.

"Nephew do you not listen in the meetings? You are the Fire Lord" said Iroh. If the situation had been any different, Katara could have laughed. Zuko was one of the most powerful men in the world and here he was, with his uncle telling him off.

"Cut the lecture Uncle. Who is she?"

Katara would have to make her name clear. She was not going to be referred to as she and Waterbender all of the time. Why not now? Katara pushed herself off of the wall and side stepped around Zuko bravely.

"My name is Katara, not Waterbender and I am the sister of Sokka" she seethed and stepped forward towards Zuko. "Do you remember him? The one that you threatened to have killed?"

Now it was Zuko's turn to look shocked. If that was possible. His expression hardened.

"Your brother is the Chief?" Zuko looked at her briefly and then over to his Uncle. And then smirked. "Good choice Uncle. I'm glad that we didn't kill her. She will be very useful" Zuko said. The smirk on his face scared her. He reached forward and grabbed Katara's arm.

"You're coming with me, Katara."

She was pulled out of the room, shoving past Iroh. Zuko's grip was tighter then the guards had been. Clearly the Fire Lord had no regards for handling anyone with care. They sped along the hallways and Katara tried to keep track of how many lefts and rights they had taken and what doors they were passing but everything looked the same. Escape would be difficult. They finally stopped at a door, and Zuko slammed it open. He still held her as they walked inside. When he left her go, her arm tingled. His grip had been extremely warm and she was surprised he hadn't burned her. Zuko turned around and locked the door, making sure to shove the key safely in his pocket.

For the first time Katara noticed that he wasn't in the layers of armour that he had been in before. He was in loose red trousers and a loose red shirt with a deeper red and orange vest over the top.

She was in the middle of the room now, looking at him with a look of hate. He embodied everything that they fought against. He was the reason that so many of her people had been killed. Including her father.

Katara glanced around the room quickly. There was a large bed pressed against the wall, with two tables either side. A wardrobe was near the window and in the corner was a table with two chairs. It was large and luxurious; clearly Zuko's room. He wouldn't slum it like his staff had to. Pretentious ass. She looked back to the Fire Lord. He was looking at her already.

"I thought you'd have taken me to a dungeon" Katara noted.

"Are you asking?" Zuko questioned. Katara said nothing.

"Besides I'm not letting you out of my sight from now on. Not now that I know how valuable you are" said Zuko, taking a step towards her.

"What do you think you are going to be able to do here? I won't tell you anything" hissed Katara, taking a step backwards. She wouldn't allow him to be anywhere near her.

"I wasn't expecting you to tell me anything. I understand about loyalty" he took another step forward, as she took one back. Katara knew how this would end up, and didn't want to be cornered. Zuko continued onwards. "But I can just imagine the things that I could request from your brother." He now stood directly in front of her, looking downwards. Katara formed a plan in her head. There were plants in the room. She would absorb the water from them and attack Zuko and take the key. It was a slim chance but anything was better than being stuck in a room with him. Zuko had stopped talking and was looking at her with an odd look. Almost like he knew what she was thinking. But of course that wasn't possible.

In a split second she kicked her foot up, thankful for the years of training and it hit Zuko's stomach. He stepped backwards, momentarily shocked and Katara seized the advantage. She reached her hands out and pulled all of the water out of the two plants in each corner of the room and created a whip, directing it right into Zuko's chest. It really did help that he wasn't wearing any armour. He fell to the floor and Katara quickly used the rest of her water to freeze his hands to the ground. Katara then rushed forward and grabbed the key. She ran to the door and quickly and put the key in. it wasn't budging and she pushed with her strength before finally hearing a click.

As she pulled it open, it was slammed shut again.

Zuko had unfrozen his hands a lot faster than she had anticipated. Katara could almost cry. That was the only source of water in the room and now it was gone. She would have to think of another plan. She tugged on the door, but Zuko's hand was above her shoulder, holding the door shut. No matter how much she fought, Katara lacked physical strength. Zuko was directly behind her and for the first time, his heartbeat was slightly fast. She hope her whip had hurt. Zuko roughly grabbed her shoulder and turned her around, shoving her backwards harshly. She collided with the hard metal wall. He took the closing step between them.

"Don't ever do that again Katara, otherwise next time it won't end well for you" he hissed. He was breathing heavily and Katara could feel it with every breath.

"Just kill me now Zuko. I'm not going to surrender to you, so kill me. I won't be of any use to you" she replied.

"I can get your brother to do just about anything for me to ensure your well-being. I won't be killing you Katara" he grabbed her shoulders and turned them both around. He shoved her backwards and took steps forwards once again. His hands were on her shoulders once again and she fell backwards. Onto the large bed.

She sat back up quickly but Zuko was on top of her in an instance. He straddled her waist.

"Get the hell off of me!" she yelled. Katara reached out, swinging her fist towards his face. He grabbed her wrist and shoved it down next to her head.

"I said I won't kill you Katara, but I didn't say that I wouldn't find other ways to make you…behave" he looked down at her heaving chest. It had been the wrong day to wear her dress.

Katara couldn't believe the predicament that she was in. She was pinned underneath the Fire Lord, the evil ruler. Many times she had vowed to kill him if she had ever met him and now here she was, feeling powerless.

Zuko leaned down.

"You will be here for a while, and I can make your stay either very painful or pleasurable. I've never had a Waterbender in my bed before."

This time Katara got her hand up fast enough to smack him across the face.

"I opt for the third option. Never having to see you" she hissed out.

"As I've already stated, you aren't going to be leaving my sight. So get used to spending some time with me. And I really advise not laying another hand on me. Chiefs sister or not, you don't have to be returned to him in one piece" Zuko uttered.

"As if I would lower myself to being in your bed" she spat out at him. Zuko tightened his grip on her wrists, heating them up.

"You'll be in my bed if I want you to be. Do you not remember who I am?" he asked. She knew he meant it rhetorically but Katara answered anyway.

"A murderer. A kidnapper. A dictator. Am I leaving anything out?"

The grip on her wrists was now burning but Katara wouldn't say anything. She had been in battles and experienced worse pain. And she would not let this monster see that he was hurting her.

"I am the Fire Lord. The ruler of this world. Your ruler. I am your better and you will show me some respect. You may have been treated like some princess in your Tribe but around here you will not be treated like such" he was leaning right over her now and Katara tried to push herself into the bed away from him.

"You are not better than me; you are the vilest person that I have ever met and you will never have my respect. You are not my ruler. I respect the people that deserve it like my brother. And the Avatar."

"Speaking of the Avatar. Do you know where he is?" he asked.

"No" she replied.

"Your brother may not have been lying before but you are lying now. Where is he? There was a reason that he wasn't on Kyoshi Island. My sources are never wrong, so he had only left recently. And you know where too." The pain on her wrists was now excruciating, and she couldn't tell if he was doing it on purpose or because he was mad. Or both. Katara cried out, and he smirked.

"I was wondering how long it would take" he said cruelly.

"I won't tell you anything about Aang. I will not let you hurt him!"

"Do you think that I won't find him anyway? I've been getting closer and closer to him every day and it's only a matter of time. So save yourself the pain and tell me what I want to hear." The heat was gone from her wrists but his grip was still there. Her wrists were throbbing.

"He's evaded you for this long, what makes you think that he won't keep outsmarting you?" she tried to shove her wrists up but it didn't work. Instead his smirk grew. "And why are you so bothered by him? As you've stated many times, you are the Fire Lord. You have what you want. You don't need to hurt him" Katara protested.

"I'm not planning on hurting him Katara. I am planning on killing him" Zuko said and finally he got up off of her. She immediately stood up quickly. He watched her, like a hunter with its prey.

"The Avatar is the biggest enemy of the Fire Nation. Even worse than you Water Tribe peasants. He gives you all a pathetic hope that you can win. Once I crush him, I crush you all" Zuko said.

"We will not lose hope even if Aang is taken from us. You are cruel, and the people that follow you are cruel. We will never stop fighting you" retorted Katara and she meant it. Zuko stepped forwards. "Your brother is the leader of both Water Tribes, and from what I've heard, he is also the leader of the rebel movement. Now can you imagine that he will still send his warriors into battle after I threaten the life of his precious sister" Zuko took a lock of Katara's brown hair and twirled it around his finger. "And I can make him many promises until I kill you. I can hurt you. I can have my way with you and when I'm done with you, my men can have their way with you. Do you think your brother would let that happen? He would let me do all of that to you?"

"You're a monster" she hissed.

"Sweetheart, I thought that you already knew that?" he said as he chuckled. She reached forward, pushing him and punching him, aiming for his stomach and then his face. The things he was saying were pure evil and she couldn't let Sokka surrender because of her. She would not be the reason that the rebellion lost hope. She did land a few good hits in before Zuko finally grabbed her arms, and then backhanded her. She fell to the floor from the sheer force. Then he was in front of her, with a hand on her chin, pulling her back up.

"What will get it through your head? I am in charge here. Do not lay a hand on me" he said, staring her down. Her chin in his hand forced her to look up at him. There were tears in her eyes but she'd be damned before she let a single one fall.

"My brother will not follow any of your requests. And neither will I" she forced out.

"Then life on this boat will be very hard for you" was all he said before releasing her chin. She fell backwards but caught herself. Zuko turned away towards the door and stopped just before he opened it.

"How did you do that Bending? With the plants?" he asked, looking over his shoulder at Katara. She was rubbing her chin but stopped and looked at him.

"As if I'd tell you" she snapped.

"Fine. Another thing that I'll know to keep away from you. When I come back, I hope that you'll be more compliant. This rebellious act is wearing on my nerves" he finished and walked out of the door. Katara heard the click of the lock, and knew there was no point in trying to open it.

She was wearing on his nerves? It was obviously the other way round. Zuko was pompous and expected everyone to just follow what he said. He had another thing coming from her. She wouldn't follow his orders. Zuko could kill her. As long as her brother kept fighting and the Rebellion was kept alive that was all that mattered. But even so, she wouldn't go down without a fight.
