All Four
Julie had no idea what just happened, but the next second there was a ripping noise and the other three were standing there again. As were all of their friends, the ripping noise stopped and everyone watched the world around them slow down and stop moving. "Where are we" Katara asked. "Yeah what happened" Bart asked. "Our destinies" Aang answered.
The four avatars went marching off to where the ripping noise came from and they all stood around waiting. "If this place is the joint place of space and time, then that means our enemies are nor our real enemies" Julie said. "What" Jake said looking at Julie. The next second Sozin came walking out of a hole in the ground "hahahahahahahahahaha" Sozin said "the avatar I presume". Aang went into the ready stance, but Julie, Jake and Korra could not move. "Hey I can't move" Jake complained. "What" Aang said as Sozin came at him. "Hey I get it" Julie said "You are actually fighting the comet Aang". "What" Korra said looking at Julie as though she were insane. "The comet, Sozins Comet, you are fighting it use my fire power to fight it" Julie said.
"How" Aang asked. "IDK" Julie said. "IDK?" Aang said confused. "I don't know" Julie said. "No what does IDK mean" Aang asked. "I don't know" Julie said. "Then why did you use it" Aang said annoyed. "No IDK means I don't know" Julie said. "Oh" Aang said. Aang ran away from the comet. "Don't run away fight it" Jake said. Aang grabbed Jakes arm and the next second was inter connected with every avatars earth bending. "I think I get it the person you touch is the bending you get" Aang said using earth bending "but I do not need earth bending right now". Aang grabbed Julies hand and used her bending. Aang beats the comet and it is Korras turn. "What is that" Korra asked as a weird shadow appears. "It is Jupiter" Jake said. "No it is the earth" Julie said as Aang agreed.
Korra grabbed Aangs hand and used his air bending, but it wasn't doing it properly. "You need to stay calm and feel it" Aang said. Korra tried again and ended up doing it. "It didn't work" Korra said annoyed, so she tried again using Jake. "I am getting nowere" Korra said as his bending didn't work. "Try a mixture of moves" Julie suggested. Korra grabbed Julie and Jake. "That did it" Korra said as Jake was released. "Ok me next" Jake rushed around the room and managed to find the correct combination against the moon. Now Julie was up against Jupiter. Julie beat Jupiter and the four avatars were thrown back into their own time. Time is now restored and what they knew was that they would forget their adventure until they became a full-fledged avatar.
Air
Aang remembered his adventure with his future lives, but his friends did not remember seeing them. "Are you sure we saw them" Sokka said. "Yes" Aang said as he felt even more ready to fight Ozai.
Water
Korra wondered how she got to the middle of Republic City and why she was even there. With a shrug Korra went back her home. Unaware that she had just saved the world.
Earth
Jake glanced at his friends who had no idea why they were all in the middle of the woods. Jake had no idea why they were there, but he was going to find out. Eventually.
Fire
Julie remembered what happened and was grateful that the others had helped her return home. Her family has no idea how Julie won, but the signed paper says otherwise.
All Four
One Thousand years later:
The older version of Aang waited for Older Korra, Jake and Julie to arrive. "About time you guys" Aang said. "Give us a break being dead for a few hundred years can do that to a person" Korra said. "Yeah and besides I am not used to doing so much work anymore" Jake complained. "I had to wait for these slow pokes" Julie remarked. "So how are they doing" Korra asked about the four new avatars. "Well, soon we will have to give them the message" Aang said. "Hmm" Julie said watching the fire bender "A true hothead, just like Jake". Jake gave Julie a sour look. "Well this will be the last time we are useful" Korra said. "Come on gang time to change the world again" Aang said.
"Where are they" the fire bender said angrily. "Are we too late" the water bender said worried. "Nah don't be worried" the air bender said. "So where are they them Mr. Smarty Pants" the earth bender said. "Welcome" Aang said "We are the four avatars before you who had this amazing phenomenon happen to us". "Yes, we were just as confused as you, maybe even more than you" Korra said.
"But here is the reason why you are here" Jake said "Every one thousand years there is rare alignment that will boost an avatar". "The bad news is that if there is only one avatar then that avatar will end up being stripped of their bending" Julie said "and then they have to wait a few years to train the next avatar". "But how can they train them if their powers are gone" the water bender asked afraid. "Train them mentally" Aang said "in the next few minutes you four will be thrown into your own time and then your times will combine, as ours did". "During this time the four of you, will have full access to everyones bending skills" Korra added. "But I can't air bend" hot head said. "Or fire bend or air bend" the water bender said. "You will" Julie said. "Now go" Jake said. "Beat your enemies and save the world together" Aang, Korra, Jake and Julie said at the same time.
The four new avatars left and the old four were left behind. "Well that was time out of my death I will never get again" Jake said. "Oh shut up" Julie said as they waited for the other four avatars to turn up and continue their legacy.
