Sacrifice

I still don't own ATLA

I'm really sorry but I'm going to have to end Rogue Airbender early (sort of) I'm splitting it up into two Stories "Rogue Airbender" and Part Two "Rogue Avatar" so I can take a break and focus more on my other stories for awhile.

For now enjoy this last chapter.

Ryu looked around him, he was in the same exact spot he'd been in the first time he was in the Spirit World. It occurred to him he had no idea what direction to go in to find Ari.

"Great, maybe I should have thought this through a bit more." He said to himself and started walking, before long Dark Spirits appeared around him. Ryu drew his swords and took a fighting stance, waiting for them to attack. The first spirit attacked him from behind. Ryu twisted and stabbed it through the chest.

"Great, now I'm killing Spirits." He thought "If I get out of this Aang is going to kill me." Ryu finished off the rest of the Dark Spirits and quickly moved on eager to get away from the Spirits.

After walking for awhile Ryu stopped he wasn't as in tune with the universe as Aang, but he could tell when something wasn't right. Ryu turned on the spot, looking around. He didn't see anything unusual.

Ryu took maybe three steps before he was attacked from behind again. Instinctively he tried to airbend and was surprised when the Spirit was thrown off him.

Ryu stared at his hand for a second then fired an air blast at the Spirit again. Another appeared and Ryu launched a fire ball at it. It didn't seem to have as much of an effect as the airbending and much less than the swords.

More Spirits appeared out of the ground Ryu drew his swords again, using them to direct air currents, forcing the Spirits back. When he saw an opening Ryu ran for it firing air blasts as he ran.

A spirit caught up with him and grabbed him around the neck. Ryu tried to fight it off but it was too powerful. An instant later the world vanished.

Sometime later Ryu woke up and groaned. Looking around wherever he was, it wasn't a place he recognized. It looked more hellish than even Koh's lair. There was a large beam of light shooting into the sky. When he saw that his mind clicked.

"The Spirit Portal." He thought. Nearby he saw a figure lying on the ground. "Ari!" he said scrambling to his feet and rushing over. Just before he reached her an energy blast threw him back.

Ryu rolled over and saw Vaatu floating nearby. No. How had he escaped?

"How did you escape?" Ryu demanded.

"Your young friend was kind enough to let me out." Vaatu said.

"It doesn't matter, I'm gonna put you right back where you belong." Ryu said.

"I don't think so." Vaatu said. Ryu's eye and Tattoo's glowed, he yelled and shot a massive stream of fire at Vaatu. Turns out, he'd been holding back this whole time.

The stream of fire surprised Vaatu, knocking him back. Ryu quickly followed it up with another one. Ryu was relentless hitting the Dark Spirit over and over with a mixture of Air and Fire. Vaatu fired back with an energy beam hitting Ryu in the chest.

Ryu slammed into a rock and fell to the ground and Dark Spirits appeared around him Ryu sent them back with a fire disc, throwing Air Spikes at those that remained. Then he took off with firebending, flinging himself towards Vaatu. He crashed into him knocking him to the ground.

Ryu formed an air dagger about to stab Vaatu, when flashes appeared his eyes. They went by too fast for him to make out until he saw a battlefield.

He saw a massive battle going on, it was raining, all three nations were fighting each other. Near the center, he saw two figures wearing battle armor: one with Symbols from the Four Nations, the other only Fire and Air. Thunder crashed as the two figures collided.

"Air and Fire will collide."

Ryu caught a glimpse of Zuko fighting Sokka, Toph fighting Katara.

"Friend verses friend."

The figure wearing Fire Nation armor swung a sword at the Air Nomad. He spun around revealing it was Aang! Ryu gasped when he saw Aang's bloodied face.

The Fire Nation Warrior turned around slightly, allowing Ryu to catch a glimpse of a scar on his face.

That was him! Ryu recognized the scar as his own.

"Brother verses brother."

Ryu caught a lightning strike and redirected at Aang.

"Lightening will strike."

Aang tried to redirect it but it was too strong, he fell to his knees.

"An Avatar will fall and darkness will rise."

The Ryu stood over Aang, spinning the sword in his hand and plunged it into Aang's chest.

"No!"Ryu shouted, collapsing to his knees, hands on the sides of his head. "What did you do to me?" he said tears forming in his eyes.

"I simply showed you your destiny." Vaatu said. "Join me and we can prevent it."

"My friends will be safe?" Ryu asked.

"Of course." Vaatu said. Ryu stood there for awhile thinking.

"Okay." He finally said. Vaatu laughed and rushed at Ryu entering his body.

His tattoos and eyes glowed red briefly then dimmed. Vaatu couldn't get a full hold on Ryu but neither could he escape.

"What have you done!" he demanded trying to break free.

"Where ever there is darkness, light will rise up against it." Ryu said.

"No!" Vaatu yelled, realizing what was about to happen. Ryu slammed his fists together but instead of creating the usual vortex around Ryu it caused a massive explosion that destroyed a good part of the landscape and the spirit portal along with it.

Epilogue

Aang tossed and turned in his bed at his home in Ba Sing Se, Something was wrong, he couldn't sleep and it had nothing to do with his battle with the Fire Lord a few months ago. He got up and went down stairs to get a glass of water. He heard a knock on the door. "Who on earth?" he wondered. "It's the middle of the night." But he answered the door anyway being the Avatar people always wanted his help.

He got the shock of his life. "Ryu!" he exclaimed. "Avatar Aang." Ryu said bowing.
