The top of the ancient rocky statues above was Aang and the Ozai fighting until the end. Aang could not manage to get one hit on him and knew he was running out of time.
"Your time is up little boy!" Ozai taunted as he chased Aang.
Each time Aang touched the ground and led Ozai to almost blasting him from the top, but Aang was lucky to be quick and to get away. Lightning strikes from Ozai's fingers were nearly close to striking Aang's back and almost at the same spot Azula had critically injured him. Aang was not to give up though. He had made another tornado and whirled himself inside it, spinning him all the way to the bottom of the battlefield and gasping for air. Ozai flew all the way and chased Aang without breaking a sweat nor tired from chasing. Aang looked up in complete exhaustion and started to run away from Ozai.
"Please! You don't know what you're doing!" Aang yelled while he tried to earthbended rocks at Ozai's body.
"Yes, I do. I am about to be the most powerful person in the world!" Ozai responded.
The roar in his voice matched completed with the amount of fire he released from his body, and Aang knew he could not ignore the power that was headed towards him. Aang quickly earthbended rocks around himself to try to protect himself from getting blasted. The fire shook him to the ground and the rock rolled and Ozai did not stop firing. He had much energy to spare and had plenty of time to get rid of the avatar before the comet ended.
"Come out and fight! You can't hide in there forever Avatar!" Ozai yelled as he continued to scorch the rocks with fire at Aang.
At The Fire Nation
Zuko and Katara had finished battling Azula and rushed over to where all of the air ship fleets had left. There as nothing but one more air ship with nobody inside.
"Come on Zuko, we have to meet up with Aang!" Katara yelled and grabbed his hand.
Zuko ran as fast as he could still with his injured body and came inside until he met a couple of fire nation soldiers.
"I got them." Katara said determined.
She rapidly froze all of the soldiers to the walls and ran right past them into the commander's room. She took care of the wheel and led the air ship in the air heading to where Ozai and Aang were battling.
"This is going to be a rough ride." She said with much angriness in her voice.
In the meantime, Aang knew he couldn't hide forever and time would come to where he would have to just try to fight the Phoenix King. Ozai backed away and stuck is hand out, preparing to unleash one of the most powerful blasts he had ever sent. He took another leap towards the hiding Avatar and unleashed the blast, crushing the rocks and blasting Aang to another rock statue and another sharp rock sticking out on most of the others. The rock hit Aang's scar on his back and gave him visions of all the Avatar's and allowing him to unlock the avatar state. Ozai grandly walked over to the appearing fallen Avatar, taunting him as he made his way.
"Come on out little boy, you're about to be…" Ozai said but was stopped as he saw a glowing arm and hand grabbing his hair.
Aang came from the bottom of the ground and blocked away Ozai's right arm trying to aim another hit at he Avatar. Aang let go after the block and unleashed a powerful air wave, sending Ozai to the ground and falling until he had slammed his back into another rock and fell to his knees. He looked up and watched as Aang brought all four elements surrounding him, air as a big air bubble covering his whole body. The fire, water, and rocks circled him as he rose from the ground and into the air facing Ozai's direction. Ozai was frightened and tried to fly away from his firebending. Aang caught up very quickly and the two most powerful people in the world fought while flying in mid-air. Ozai would not stop fighting though. Aang quickly earthbended two of the rocks statues and blocked Ozai from flying threw. Ozai managed to change his direction, trying to ignore Aang's single moves. Aang then drew water from the nearby sea and wiped Ozai completely from the air and fell to the ground. Aang flew from above about to seemingly smash Ozai to the ground but he did not hesitate and flew quickly away from the Avatar singly crushing him. Ozai headed for wherever he could and watched as Aang was a step behind him. He made his way on the top of another statue and kicked a flame at Aang, but he quickly blocked it by earthbending rocks in front of him. Ozai then jumped and flew away again and Aang went after him once more. After a couple of seconds after Aang blasting fireballs at Ozai, he grabbed his body with water, covering his whole body inside and swung the water around and splashed Ozai on the ground with the water on top of him. Aang then earthbended Ozai's hands and feet to the ground and flew upon him making his final stand.
Katara and Zuko finally had seen the crashed air whip Aang had destroyed and new they were getting near. They saw Suki, Toph, and Sokka waving in on the ground letting them know they were ok.
"Over there, straight ahead." Zuko said pointing at his father.
"I think Aang's winning!" Katara said with slight joy on her face.
"Fire Lord Ozai, you and your forefathers have devastated the balance of this world. And now, you shall ay the ultimate price!" Aang yelled while still in the avatar state.
Ozai watched as Aang was bending all of the elements towards his chest but then soon stopped and the water fell on top of him. He knew by now Aang had exited the Avatar state and watched as he slowly went to the ground.
"No, I'm not going to end it like this." He said refusing.
"What is he doing?" Zuko asked about to get out of the air ship.
"No…" Katara said lowly.
"Even with all the power in the world, you are still weak." Ozai said about to strike once again.
Aang did not bother to pay attention and Ozai stealthy stood up from the ground and prepared to strike Aang with lighting. He swung his arms into circular motions until he finally got the striking point. Katara ran out of the air ship and ran to the edge of the statue and watched Ozai to make his final strike.
"Aang!" Katara yelled far enough for Aang to hear.
Aang was bout to turn around until he felt a small sting on his back, the same spot to where Azula had struck him back at Ba Sing Se. His eyes suddenly turned to fear and struck with pain and turned around completely looking into Katara's blue eyes. Smoke had covered Ozai's finger tips and he smiled and knew the Avatar had fallen once and for all. Zuko and Katara watched along side with Suki, Sokka and Toph. Katara took another step off of the edge not knowing she would fall if she took another step. Sokka grabbed his sister before she fell and they both watched as Aang fell from where he stood and to the ground.
"No!!" Katara yelled with much anger and sadness filled inside her.
Ozai laughed and faced the gang with much power still inside him. He looked up and still saw the comet soaring by, knowing he still had time to end the gang.
"Now, I have nothing to worry about. I took the avatar down and now, I'm going to take you guys down!" Ozai yelled and started to fly towards the gang.
"We've got to get out of here!" Suki said.
"No. We're staying, for Aang." Sokka said saddened. "Just give him everything we have."
Katara watched as Ozai flew nearby wanting to unleash everything she had in store for him. "This still isn't over."
