A/N - Alright...I'll do my best here. I've never written a battle scene before, so...yeah. Wish me luck.
Ozai flung back with the force of the fire. He grunted in pain as he rose again. He jumped into the air and kicked flames at me, and I leaped out of the way, firing back a spew of fire. We battled back and forth for sometime. We heard grunts and cries from Azula and Iroh's battle. I worried constantly about how Sokka and Katara were doing outside, but mostly I focused on dodging and shooting flames. It was an extremely intense battle, and I was, surprisingly, winning it! After a time, an ear-splitting screech could be heard, and all battling in the Dining Hall stopped, as we watched Azula fall into a large fire that had started on the carpet. She writhed under the extreme heat, screaming at the top of her lungs, but she was too weak to get herself out of the flames. After a few moments, the screaming stopped, she stopped moving.
"Azula!" Ozai cried, and he dragged her out of the fire. She lay there, still not moving. The Fire Lord stood staring at his dead daughter, then turned back to Iroh furiously. "Look what you have done to my precious little girl!" he yelled. Then, he his hands into fists, pointing out his index and middle fingers. He waved his hands in front of him, and they started to spark. I watched in awe as the sparks jumped from hand to hand, causing mini-lightening. Suddenly, he shot a huge bolt of lightening from his fingers at my uncle. I stood rigid, in extreme shock. I hadn't even known it was possible to shoot lightening! What surprised me even more, was that Iroh caught the bolt in his two fingers, and drew his hand down his arm, down to his stomach, then up out his other arm, back out! The lightening struck the corner of the ceiling, which crumbled to the floor.
As shocked as I was, I realized my chance, and shot one last blow of fire at my father, straight at his chest. He stumbled backwards with the force of it, and I shot him again. He now fell to the floor, and I fired one last spew of flames, again at his heart. "H-H-How-w-...?" he gasped, and his chin fell to his chest. He was dead; I had done it. The Fire Lord was dead.
I took a moment to catch my breath, and I fell to my knees with pure exhaustion. But suddenly, there was a flash of white light, and I was a translucent blue Aang standing before me.
"A-Aang?" I asked incredulously. He nodded soberly. "I'm so sorry, Aang! I-" He held up his hand to stop my apology.
"It is alright, Zuko. You have done it." he said.
I looked at my dead father briefly. "Yes. I have killed him and therefore ended the war." I said.
"You have done more than that." he said, "You have saved the Avatar's spirit."
"What?" I exclaimed.
He smiled. "Since you have done something so against your original thoughts, and for the good of the entire world, the Spirits have decided to fix your mistakes."
"How?" I asked curiously.
"Your first-born child-" he began, but I cut him off.
"Who says I'm going to be father?" I asked defensively.
Aang chuckled. "Zuko, I've known for sometime that you're in love with Katara."
"Y-You d-do?" I stuttered.
He scoffed playfully, "You think I didn't notice you glaring at me whenever we got romantic? I did. You're in love with her, and it's okay. She doesn't really have any chances marrying me, now, does she?" He laughed, but a bit sadly.
"I'm sorry, Aang. I promise I'll take good care of her." I said, and he nodded.
"Anyway, you're first-born child will be the Avatar. And, any other children you have will be Airbenders, to help them repopulate." he said. My eyes opened wide, but I smiled.
"Thank you, Aang. And thank the rest of the Spirits while you're at it." I said, and he nodded.
"Farewell, Zuko. You've done well. Oh, and, good-bye General Iroh." he added.
"Good-bye, Aang. I hope to see you again someday." he replied, and Aang nodded, and disappeared. I stared back at Iroh.
"Uncle, how were you able to see him? Spirits always only visit one person and can only be seen by that person!" I cried.
He chuckled. "Oh, I've always been able to see the spirits. It's an old story that I'll tell to you someday." he said, and I sighed tiredly. I suddenly remembered Sokka and Katara, mostly because they burst through the door with about 20 guards behind them. I took a battle stance, but Sokka put his hand up to stop me.
"Don't worry, Zuko, they're on our side. They were the ones Ozai was talking about when we first came. The ones who didn't support the war. We were just coming to see if you needed any help." he said.
"Uh, no we're good." I said a little uncertainly.
"Oh my gosh, are they dead?" Katara cried, looking at Ozai and Azula. She looked a little sick at the thought.
I walked over and put my arm around her protectively. "Yes. And we'll be fine now." I said.
"Yes, we will." Sokka said, smiling at me. I knew that this sentence had an under-meaning. Sokka was telling me that he was accepting the fact that I was going to date Katara. Speaking of which, she now looked up at me with frightening, hopeful, child-like eyes. I leaned down and kissed her cheek, and she turned her face to kiss me fully, and I wrapped my arms around her waist. "Alright, just because I'm okay with it, doesn't mean I'm okay with you doing it right in front of me!" Sokka cried disgustedly. Katara pulled away and rolled her eyes at Sokka, and smiled at me. I smiled back, and chuckled at Sokka's disgust. I began kissing Katara again, as if in rebellion. "Aw, man!" Sokka complained. Iroh laughed heartily. I knew everything would be perfect from here on.
