Sora had been travelling the timelines for what seemed like an eternity. He had changed a lot; he had smoothed down his hair slightly and allowed it to grow out to his shoulders. He had changed his coat slightly, it now resembled a black assassin's coat; it however still had the blue flame motif on the sleeves and coattails. He slipped away from his duties one day and visited the avatar's world. He saw much has changed; at least 30 years had passed. He was in the southern water tribe and, well, "tribe" was sort of an insult to the icy metropolis. It was a city similar to the northern tribe but was slightly larger with the actually villages in the surrounding area. He was walking down the street with his hood up and was suddenly was blasted by a ball of air. He slammed into the nearby wall his hood somehow remained up. A similar *shing* noise graced his ears and when he looked up he was looking down the blade of a warrior's Keyblade. He looked past the blade and saw airbender tattoos and an Abe Lincoln style beard. It was Aang, now age 43.
'Shit…' Sora thought, 'probably should've been a little more subtle than a black hooded trenchcoat.'
"We routed your invasion when we defeated Ozai and the rest of your allies. Why have you returned?" Aang demanded as someone joined him at his side. Sora looked at the new person; it was a 47 year old Katara, at least 7 months pregnant. Sora smiled, 'So you two did find happiness after all…' he thought quickly about all the ways he's disguised his identity in the past, he needed something new.
"Invasion? What the heartless invaded this world too?" Sora said with a fake British accent.
"No not heartless, some new enemy, they resembled black dragons," Aang said. Sora's eyes narrowed in anger and was about to asked questions when heartless suddenly appeared.
"Lookout!" Sora shouted as he weaved around Aang's Keyblade and blasted the heartless with a dark firaga.
"Talk later!" Sora said as more heartless spawned around them. Suddenly a hooded figure appeared among them.
"Friend of yours?" Katara asked.
"No, and he's soon to be dead," Sora said. The stranger lowered his hood, revealing a young Xehanort.
"Katara. Leave," Sora ordered. Aang and Katara looked at him.
"How do know her name?" Aang demanded. Sora lowered his hood and batted his hair spiking the top up. He then drew the Kingdom Hearts 2 version of Ultima.
"Anymore questions?" Sora said smiling over his shoulder, "Aang take her from here she's in no condition to fight." Suddenly he heard the sound of a blade cutting flesh and a half dozen heartless disintegrated. Katara stood a few feet in front of him with the Brightcrest Keyblade drawn.
"Anymore questions?" Katara said angrily, yet she was smiling. Sora chuckled as he leapt at the horde with Katara and Aang close behind.
After the Horde was destroyed the three friends pointed their weapons at Young Xehanort.
"Leave this place and never return," Sora said.
Xehanort smiled, "Sure, but unless you leave soon your presence will force the Infinite to send more to exterminate you," he said vanishing. Sora dismissed his weapon as did Aang and Katara. Sora started to turn around.
"Well let's continue our little cha…" Sora was cut off by a hard slap to the face. This sent Sora sprawling to the cold ground. Katara stood over him, tears streaming down her face. She turned around and ran off crying.
"Sorry 'bout that," Aang said helping Sora up.
"No worries. I deserved tha…" Sora started before getting punched in the face. He got sent sprawling again.
"Goddamnit!" Sora snapped.
"You deserve a lot more than that you bastard," Aang said, "You stole Katara's heart and shattered it just as quickly. She didn't fully recover until after the Earth Kingdom fell during the war. Watching me die for the first time snapped her out of that slump you put her in. I should beat you into a bloody pulp for what you did. But for Katara's sake I won't," Aang said infuriated.
"Thanks?" Sora said.
"Leave, and don't come back until you're ready to apologize to her. And no you're not doing it now because I know that she won't forgive you right now," Aang said and he turned and ran after his wife. Sora's head hung low, a waterfall of tears escaped his eyes as he clenched his eyes and teeth shut. He had forgotten how bad love could hurt; he'd been gone so long he thought he had moved on from Katara. But seeing how his mere presence upset her on such a level brought more pain out of him than he had ever felt in his entire life. He dragged himself up from the snow and brushed. He cleaned the tears from his face, lifted his hood, and opened a time tunnel. He walked slowly through it. He had a new drive, kill the being that had causing him and Katara so much pain. Kill the one who had tricked him into giving up everything he loved. Sora had a new drive, the death of Murozond. He would murder the Lord of Time.
"Lord Murozond, that boy you recruited…Sora? He's gone rogue, he's already slaughtered an entire flock of whelps in one of our nests," a woman reported. Murozond smiled evilly.
"Our goal is almost within sight. The king is almost in checkmate. Soon the damage will be repaired, the Infinite will be no more, the last of the Keyblade wielders will be destroyed and all will be well," Murozond said.
"How will we get rid of Sora?" the woman asked.
"Lure him to this world," Murozond ordered. The woman looked at the image Murozond showed and cocked a brow.
"Why this world my lord?" she asked.
"This world has advanced technology and knows of other worlds; this world, however believes it has found none with life. If Sora gets arrested in the world he'll be locked up just long enough for my plans to move forward."
