"I guess their's no use hiding it anymore" Ozai crosses his arms "yes, I killed that pathetic father of yours"

"You said he died at war!" Kira shouts

"Now now I did it for your own good" Ozai smirks and places his hand on her shoulder "look at how strong you've become without him holding you back. You followed the plan perfectly, you even married my worthless son"

Kira growled and pulled away from him "I married Zuko because I love him! ..Iroh was right.. Zuko was right, Aang is right!"

"Don't you dare turn on me!" Ozai shouts "I created you!"

"No" Aang gets out of his sphere and stands next to Kira "you're wrong, Kira is her own person, she has the right to chose her own path" Aang turns to Kira "you're not the dark avatar Kira, you never were, you're not evil"

"then.. what am I?" Kira asks

"I met an old lion turtle who taught me a lot about myself and the past" Aang smiles "he told me about you, you don't have an avatar state because you're the switch. If I die you take over, that's why you can bend all the elements"

"So...I'm not evil?" Kira questions

"No" Aang shakes his head and looks at Ozai "but he is, he's manipulated you your entire life into believing your someone you're not" Aang looks at Kira "So help me end this war and make things right"

"You got it Aang" Kira smirks

She and Aang stand next to each other proudly and take a fighting stance.

Ozai growls "You ungrateful-"

Aang and Kira send a unified air blast at Ozai sending him tumbling back.

"Ok as my switch I need you to help me into the avatar state" Aang says quickly "it's part of the reason my avatar state was always out of control"

"got it whatever you need" Kira agrees

Aang quickly explains to Kira what they need to do. Kira and Aang put their hands together and start mumbling words, Aang's eyes and tattoos start to glow.

"Get him Aang!" Kira cheers

"Help when you can" Aang tells her before taking off

"Right" Kira follows him

Ozai tries to firebend at the Avatar, but Aang merely knocks his hand away. He creates a blast of air sending Ozai flying backward. He crashes into a pillar of rock. He falls down to the ground and as the dust clears he looks up at Aang in the sky with a sphere of air around him. Aang proceeds to roar and creates fire out of his mouth, fists and feet. 

Kira creates a massive gust of air causing Ozai to cover himself as he groans in struggle. Pillars of earth disintegrate and move toward Aang as other pieces of rock rise up from the ground to surround Aang. Water also rises toward Aang as he creates a ring of fire around himself. 

The earth begins to create a ring inside the air sphere as the water continues to rise up and form another ring inside the earth sphere. Ozai watches while covering his head with his arms. Aang is now surrounded by a ring of water, a ring of earth, a sphere of air and a ring of fire.

 Aang charges at Ozai, ramming him, and blows him off his Elemental Sphere. Ozai flies away from Aang. Kira uses earthbending to shoot machine gun-like earth bullets at Ozai while Aang chases him. Kira then uses earthbending to move two pillars in front of Ozai, who recoils and flies away. 

Aang takes the chance to send a wave of water at Ozai, causing him to crash to the ground. As Ozai recovers and looks up, Aang bursts through the pillar he landed near. Ozai retreats backward and shoots a stream of fire at Aang. Aang drops to the ground narrowly missing Ozai who propels himself away with fire from his feet. 

Aang rises and begins following the fleeing Ozai again. Ozai lands on a pillar and launches a wide fire blast at Aang, who uses earthbending to move two large pillars to protect himself. Aang breaks and lets the pillars fall as Ozai flies away again. Aang unleashes multiple blasts of fire toward Ozai, who manages to dodge them. 

Ozai lands on the side of a pillar and launchers three similar fire blasts at an approaching Aang, who uses air and water to disperse them while Kira fires a strong blast of air at Ozai, disintegrating the pillar he stood on but he manages to get away. 

Aang continues to chase him as Ozai looks back, realizing Aang is catching up. Aang moves his arm in a circular motion causing water to wrap itself around Ozai's leg and up to his outstretched arm, whipping him around, before slamming him on top of a pillar. Aang flies forward and earthbends Ozai's hands and feet to the ground, trapping him. Helpless, Ozai watches fearfully as Aang hovers over him, his voice echoing with the fury of his predecessors.

"Fire Lord Ozai, you and your forefathers have devastated the balance of this world, and now you shall pay the ultimate price!" Aang, under control of his past lives, combines all four elements together for his final attack. At the last second, however, he manages to regain control; he comes out of the Avatar State, lets his attack die out, and floats to the ground, freeing Ozai in the process "No, I'm not gonna end it like this"

Kira jumps down next to him "Why not? You said it yourself he's a terrible person, he's-"

"But killing him wouldn't be right" Aang says

"Even with all the power in the world, you two are still weak!" Ozai shouts

Ozai moves to attack Aang who senses it with the seismic sense he learned from Toph. He stamps down and lifts a foot up, dragging a pillar of earth along with him, deflecting Ozai's attack and binding him inside the rock. He circles Ozai and proceeds to bind his other hand as Ozai attempts to attack again. He pulls the rocks down into the earth slightly, causing Ozai to kneel. 

Ozai attempts one final fire breath attack, but Aang uses airbending to stop and approach him and puts one hand on Ozai's forehead, and one on his chest, while he watches in horror.

"What are you doing?" Kira asks

"No time to explain, just place your hands on my back and feed me your energy" Aang instructs "our energy has to be stronger than his"

"but how-"

"Your love for Zuko and for your nation, the length you will go to protect it" Aang smiles "and the world"

Kira takes a breath and places her hands on Aang's back. The two close their eyes. Ozai's energy begins to make its way to Aang's body, consuming the blue and replacing it with red energy. It continues to cover the beams shining out his mouth and eyes. The red energy has taken over almost completely with just one eye left. The blue energy begins to disappear.

'Iroh, Zuko, Aang, everyone.. I wont let this be the end'

Kira's energy shoots into Aang and at the last second their energy blasts out of Aang's eyes, overwhelming the red energy in the process and proceeding to take over Ozai's own body. Within seconds Aang and Kirs's energy completely takes over Ozai's energy, an intense beam of blue energy erupts into the sky. The beam disappears and Ozai falls to the ground as Aang releases him. Ozai attempts to rise and attack, but falls back exhausted and unable to bend.

"What? What did you do to me?" Ozai asks

"We took away your firebending. You can't use it to hurt or threaten anyone else ever again" Aang tells him

Aang steps forward and looks toward the sea as fire spreads on the land below.

Aang smiles at Kira "help me put it out?"

Kira nods

The two begin to bend the water from the ocean below to extinguish the fires. The water rises to extinguish the fires then returns to its normal level. Aang smiles happily as Momo returns to Aang's shoulder.

"You did it" Kira says

"No, we did it" Aang corrects her "we might've started out as enemies, but you've finally found your way"

"It feels nice" Kira admits "to win this way"

"You should be proud" Aang turns to her "cause I know Zuko will be"

-

The comet is now flying away as Sokka, Toph, and Suki are leaving the airship they were on. Sokka is being carried by the other two due to his broken leg.

"You did it! You should've seen yourselves, it was amazing! You were all like" Sokka pretends to be Aang fighting Ozai while adding sound effects "and the Fire Lord was all like" he pretends to be Ozai struggling and groaning

Kira giggles "was he always like this?"

"Yeah" Aang smiles "you'll get use to it"

Suki points to the exhausted Ozai while approaching him "So did you, you know ... finish the job?"

Ozai looks up "I'm still alive"

Suki backs away from him

"I learned there was another way to defeat him and restore balance. Me and Kira took his bending away" Aang explains

"Wow! Who taught you that?" Toph asks

"A giant lion turtle" Aang replies

"On the spot" Kira replies

Aang laughs "sorry about that"

"But it worked" Kira laughs

"...you have the craziest adventures when you disappear" Toph says

Sokka approaches Ozai "Well, look at you, buster. Now that your firebending's gone I guess we should call you the Loser Lord"

"That's not wise" Kira comments

"I am the Phoenix King!" Ozai flops on the ground while semi-conscious and drooling

"Oh, sorry. Didn't mean to offend you, Phoenix King of Getting His Butt Whooped" Toph mocked

"Yeah! Or how about King of the ... Guys Who ... Don't Win?" Suki questiones

"Leave the nicknames to us, honey" Toph says

Aang and Kira look at each other and shrug before laughing as the comet leaves the sky, returning to the darkness of night time.
