Disclamer: Don't own Naruto or Avatar: The last Airbender.
AN: Sorry about the long wait, there's a short explanation after the chapter for those interested. I hope that the chapter is worth the wait.
"I think I got it" Sokka stated as they flew through the sky on Appa "I finally think I've figured out that chakra thing."
Naruto immediately activated his byakugan and looked at Sokka and said "show me"
Sokka put his hands in the molding position.
"Yep you've got it." Naruto confirmed. "Now we can start teaching you. I'll show you the basic for the clone technique for now. Next time we land I'll collect some leaves to teach you an control exercise as well"
"Why haven't you given Katara any of those control exercises" Sokka asked suspiciously.
"First of because she has better natural control then you" Naruto said bluntly "But mostly because she will focus on the skills that supplement her water bending, while you will focus on those that help with close combat. Since she doesn't benefit as much from running across vertical surfaces as you do it seemed better to focus on things to confuse the opponents."
"But I still need to learn that clone thing?" Sokka asked.
"Yeah, being able to confuse the opponent can still be helpful in close combat after all." Naruto stated "She'll also learn the control exercises, but I'm just not teaching you in the same order."
"Oh, okay then" Sokka relented.
Meanwhile Katara is looking down at the landscape below, resting from he training with the substitution technique (Aang had his glider in his hand to dive after her if she substituted herself over the side of Appa by accident).
"Those clouds look so soft, don't they?" She said after the other two had stopped their discussion "Like you could just jump down and you'd land in a big, soft cottony heap."
"Maybe you should give it a try" Sokka said sarcastically.
"You're hilarious." Karata responded, rolling her eyes.
Aang, despite knowing that he couldn't land on the cloads, yelled "I'll try it! Yehhhh!" before jumping of Appa and dives towards a cloud. Sokka and Katara look over the side of Appa as he plunges through a cloud. A moment later Aang landed next to them with his glider, wet from head till toe.
"Turns out clouds are made of water!" He states.
"You look like you've been run through by a bunch of Katara's clones" Sokka states, earning a glare from his sister.
Meanwhile Aang just uses airbending to dry himself.
Before their argument could go any further Katara looked at where they where heading and exclaimed "Hey, what is that?"
Sokka and Aang turned towards the front to see the floor of part of the valley ahead of was black instead of the green of the surrounding area.
"It's like a scar." Sokka stated.
Shortly after that they arrive in the damaged area. Burnt tree stumps dot the barren landscape. The three dismount Appa and start walking around.
"Listen, it's so quiet." Sokka said somberly "There's no life anywhere." He then kneels to inspect some footprints on the ground.
"Aang, are you ok?" Katara said as she saw that he was looking around sadly.
Meanwhile Sokka finishes his inspection "Fire Nation!" He states "Those evil savages make me sick! They have no respect for..."
"Shh!" Katara shushes him.
"What?" Sokka whispers to her "I'm not allowed to be angry?"
Katara pointed ahead at Aang who was clearly upset. A moment later he sank to his knees in the dust, sighed and began to run his hands through the burnt earth.
"This is such a waste" he said sadly "How could I let this happen?"
"Aang, you didn't let this happen." Katara tried to console him as she walked closer to him "It has nothing to do with you."
"Yes it does." Aang stated "I might not have wielded the fire, but I also wasn't here to wield the water as an Avatar should have been. But, I don't know how to fulfill my task".
"That's why we're going to the North Pole to find you a teacher." Katara stated.
"Yeh, a waterbending teacher," Aang stated, "But that doesn't teach me how to be the Avatar. Monk Gyatso said that Avatar Roku would help me."
"The Avatar before you?" Sokka asked "He died over a hundred years ago, how are you supposed to talk to him?"
"I don't know." Aang admitted sadly. A moment later Momo crawls into his lap and he starts petting it.
While Aang had become a little stunted towards the destruction of nature due to his ninja carrier, the destruction of a forest made him think of Yamato and how he could make a new one grow in seconds. This in turn made him think of hiss other friend and how he wasn't likely to see them again.
"Hey Aang, are you ready to be cheered up?" Katara asked from behind him
"No." Aang said, then suddenly rolled to the side when he felt something approach and saw an acorn fly past him.
"Hey, how was that suppose to cheer me up?" Aang asked as he stood up.
"Well if it had hit it might have cheered me up" Sokka stated, only to receive an acorn to his head from Katara which drew a smirk from Aang, though it quickly fell. "Ow! Yeah, I probably deserved that." was all Sokka said in response as he rubbed his head.
"These acorns are everywhere, Aang." Katara said as she smiled at him and knelt beside him. Meanwhile, behind Aang, Momo was digging furiously in the scorched earth, and a moment later emerged with his arms full of acorns. "That means the forest will grow back. Every one of these will be a tall oak tree someday," She handed him the acorn "and all the birds and animals that lived here will come back."
"Thanks, Katara." Aang said with a smile, despite her misunderstanding the reason he was sad.
Just then Aang feels someone approaching and jump to his feet, startling Katara and they all turn to see and old man approaching them, or more specifically Aang.
"Hey, who are you?" Sokka asked the man.
The man ignores him as he continues towards Aang "When I saw the flying bison, I thought it was impossible, but those markings!" The mans said as he came to a halt in front of Aang "are you the Avatar child?"
After a quick assessment of the man Aang decides to trust him and nods his head.
"My village desperately needs your help." The old man then said.
Aang quickly exchanges a glance with Katara before saying: "Lead the way".
A little while later Katara, Sokka and Aang were entering the old mans village. Aang immediately noticed some badly damaged buildings on their left, one of which was down to only a wooden skeleton left. The continue walking towards one of the larger buildings, still following the old man.
As soon as they enter the building the old man addressed the people there: "This young person is the Avatar."
Immediately another man walked up to them and said: "So the rumors of your return are true." He then bowed as he continued "It is the greatest honor of a lifetime to be in your presence."
"Nice to meet you too." Aang said before looking around the room "So is there something I can help you with?"
"I'm not sure" The man says as he looks around with a pained expression.
The old man quickly steps up to the man. "Our village is in crisis, he's our only hope." He then turns to Aang "For the last few days at sunset a spirit monster comes and attacks our village. He is Hei-Bai, the black and white spirit."
"Why is it attacking you?" Sokka asked, slightly suspicious.
The chief moved towards the threshold of the doorway that the group just entered, looking at the setting sun while he said: "We do not know, but each of the last three nights he has abducted one of our own. We are especially fearful because the winter solstice draws near."
"What happens then?" Katara asked.
"As the solstice approaches, the natural world and the spirit world grow closer and closer until the line between them is blurred completely." The old man answered.
"Hei-Bai is already causing devastation and destruction." The other man elaborated. "Once the solstice is here there is no telling what will happen."
"So, what do you want me to do exactly?" Aang asked slowly.
"Who better to resolve a crisis between our world and the spirit world than the Avatar himself?" The old man asked as he approached Aang "You are the great bridge between man and spirits."
"Yep, I'll find a way to deal with it" Aang said confidently.
"Hey, 'great bridge guy', can I talk to you over here for a second?" Katara asked Aang.
Katara walked over to a nearby window with Aang and Sokka Following. Since the window is away from most of the people Katara see's it as being a good place for a private conversation. Had Aang been asked he would have pointed out that people could hide just outside the window, but wasn't really that concerned about it at that point.
"Aang, are you sure you know how to do this?" Katara asked.
"Well I don't know how to do it, but I'll just improvise." Aang responded.
Katara didn't look to sure. "So, you can help these people?" She asked, trying to get a straight answer.
"I have to try, don't I?" Aang responded "Maybe whatever I have to do will just ... come to me."
Just then Momo jumped onto Aang's shoulder and chittered. Aang was slightly surprised, but then smiled.
"I think you can do it, Aang." Katara stated while smiling at him.
"Yehhh," Sokka said with a smile similar to his sister "we're all gonna get eaten by a spirit monster."
Later in the afternoon, as the sun is setting, Aang moves out of the meetinghouse and moves towards the entrance to the village. He grips his staff tightly as an extra security.
"Hello? Spirit, can you hear me?" Aang said as he neared the gate "This is the Avatar speaking. I'm here to get you to tell me what's got you attacking these people, and if necessary stop you myself."
Meanwhile, back at the meeting house all the villagers, along with Katara and Sokka, are watching him, though Sokka isn't to happy about staying behind.
"This isn't right." He stated "We can't sit here and cower while Aang waits for some monster to show up."
The old man who lead them to the village steps up behind the two.
"If anyone can save us, he can." He stated confidently.
"He still shouldn't have to face this alone." Sokka said, staring out the window as the sun sets.
"The sun has set. Where are you, Hei-Bai?" Aang yelled "Well, spirit, uh, I hereby ask you to please leave this village in peace!"
He then twirled his staff like a marching baton before planting it in the ground like a flag, all the while having an resolute expression on his face. As he stood there he started gathering nature energy find out whether the spirit was coming or not. As he did that he noticed that it was easier then usual, and the moment he entered sage mode he understood why. Hei-bai, who was just entering the village, was expelling a large amount of nature energy from it's body, though oddly enough it felt like the spirit was actually weakened. It was like being covered in toad oil, you didn't need to concentrate that much to pull the nature energy to you, you only needed to ensure that you didn't hold on to too much.
Hei-Bai was as big as a house, with six legs and black and white orca-like markings all over his body. He is vaguely mammalian and has razor sharp teeth. It's arrival had also brought with it something that could only be described as spirit whispers.
"I'm pretty sure that you must be the Hei-Bai spirit." He stated, locking eyes with it while giving a shallow bow. "My name is" He began before jumping to the side as the spirit opened his mouth. He had feared that it was a destructive attack, but was relived to mind that it was just a natural energy inforced roar, which wouldn't do any damage, except maybe to his eardrums.
The spirit rears itslef itself up on its hind-most legs and bellows, releasing another jet of blue energy from its mouth. It gets back on all six legs and then charges into further into the village only to receive a nature enhanced kick from Aang.
"Hey, don't just ignore me" Aang said. "I was about to tell you that my nam..."
The creature suddenly moved past him at high speed, leaving a ghostly image in it's wake, and ran up to one house and destroying it. Before it could run to another Aang was in it way again.
"My name is Aang" He stated, "I'm the Avatar and I would like to help!" He was then forced to hit it away once again as it went for one of the other buildings.
Meanwhile Sokka is getting ready to join the fight, not liking how this was looking right now.
"The Avatar's methods are unusual." The village leader said as the spirit was hit once more "Though they do seem to minimize the damage to the buildings.
"But he only seems to be delaying it." Sokka stated. "Maybe we should go help him?"
"No, only the Avatar stands a chance against the Hei-Bai." The old man stated. "He is fighting it on equal terms, after all.!
"Aang will figure out the right thing to do, Sokka." Katara added.
"Please, would you stop trying to destroy everything things and listen?" Aang yelled, only to have to kick the spirit again to prevent it from destroying a building. 'I don't know what is worse; him ignoring me despite me attacking him or his obsession with destroying this village.'
At that point the Hei-bai decides that since Aang is intent on getting in it's way it will deal with him first. Aang immediately saw that the Hei-bai was aiming to swat him away, and jumped back to avoid it. However he forgot to take one thing into account; Hei-bai used nature energy. He became aware of this when one of the after images of it's arm suddenly extended and hit him, causing him to fly into a nearby building. Luckily he still had sage mode active, which absorbed a bit of the damage.
"That's it!" Sokka said as he saw this "He needs help!" Completely ignoring the fact that Aang was a better fighter then he was. He then ran towards the door.
"Sokka wait!" Katara yelled as she ran after him, realizing that he wouldn't be of much help.
Sokka quickly reached the door, opened it and ran outside. Katara on the other hand was stopped when the village leader grabbed her arm.
"It's not safe!" He stated as he pulled her back in side.
Soon Sokka arived where the spirit was towering over Aang.
"Hei-Bai!" Sokka yelled as he came to a stop and pulled out his boomerang "Over here!"
He threw the boomerang at the creature which hit the creature's butt, and bounced off with a spring-like sound before falling to the ground. Sokka then ran up to Aang.
"Sokka, go back!" Aang yelled as his face returned to normal, indicating that he left sage mode.
"We'll fight him together, Aang." Sokka stated, ignoring Aang.
"Not that I don't appre..." Aang began, but was cut of when the creature came up behind them and grabbed Sokka before they disappear in an instant.
Aang opened his staff into glider mode and took off after them, flying through the opening in the trees using the opening that mark the path into the village. Behind him he just managed to hear Katara panicking scream;
"Sokka!"
Aang just continued gliding at breakneck speed through the forest in pursuit of Hei-Bai, who is still carrying Sokka in it's grip while Sokka makes scared noises. Aang managed to pull even with it and then began to pass it.
"Aang, over here!" Sokka yelled when he saw him.
This distracted Aang so that he almost hit a branch and was forced to slow down to avoid it.
Aang speed up again and tried to catch up once again. Soon Hei Bai and Aang enter the wasteland that Katara, Sokka and Aang had landed in earlier. Without the trees Aang is able to speed up some more. As he nears the spirit Sokka sees him coming.
"Help!" He yells needlessly.
"Hang on, Sokka!" Aang yells back as he descends towards him.
Aang glided in closer, stretching his hand to Sokka, who was able to grab it. Just as Aang began to pull Sokka free, however, both Sokka and the monster vanish while Aang body fell out of the sky.
A short time later he woke up and yelled out; "Sokka!" He then looked around before stating "I failed."
After a moment he got up, deciding that he needed to tell Katara what had happened, and ran towards the village. As he neared the village he saw Katara sitting at the gate (with Sokka's boomerang in one hand) as the old man comes up to her.
"I'm sure they'll be back." The guy said.
'He's either ignoring me, or he needs to get his eyes checked.' Aang thought.
"I know." Katara replied.
'Okay, she hasn't seen me either' Aang thought as he arrived beside them, none of them acknowledged his presence
"You should get some rest." The old man said as he draped a blanket over her shoulders.
"Hey, don't you see me, I'm right here" Aang stated in an annoyed voice.
Meanwhile Katara pulled her arms closer around her, putting the boomerang close to her heart.
"Everything's gonna be okay." Katara said more to herself then to the old guy.
"Okay, so no-one can see me now?" Aang asked. He then noticed something weird he hadn't noticed before "This is my old body, I'm Naruto instead of Aang." Though he was still wearing similar clothing to Aang, though larger to fit his frame.
"Your brother is in good hands." The old man stated, cutting into Naruto/Aang train of thought "I would be shocked if the Avatar returned without him."
"Well, to a certain degree he is wrong about that" Naruto thought sadly. He looks up to see the sun rising.
"The sun is rising." The old man stated "Perhaps he will return soon."
"There is only one explanation for the fact that I can't be seen and am in my old body" Naruto/Aang said to himself "I'm in the spirit world."
The old man left a moment later leaving Katara (and Naruto/Aang) alone. Soon thereafter Katara stood up and leaned against one of the gate posts.
"I'll figure this out, Katara, that's a promise." Naruto/Aang stated "Like they said, I'm the bridge between the worlds, right? I just need to figure out what I have to do and once I do that, I'll have no problem."
Naruto/Aang then heard a noise and looked to his right,and sees Appa moved along the outside of the wall towards Katara and him.
"Appa! Hey buddy, I'm right here." Naruto/Aang said, hoping that his animal guide could feel or see him. Appa grunted and put his nose up to Katara. "But, I guess you can't see me either." He added when Appa showed no sign of acknowledging his presence.
Appa grunted at Katara once again, this time louder and made her look up at him.
"It's ok, Appa. I'm sure they're on their way back." Katara said to him while petting his noise "I bet they even found you a bunch of moon peaches for a treat."
Katara then walked back into the village, with Appa following along. Aang watched as them go before turning back to the forest path.
"What am I supposed to do?" Naruto/Aang asked himself thoughtfully, before yelling. "Avatar Roku, how can I talk to you?"
When no response was given, Naruto/Aang started to gather nature energy again to see if he could use sage mode to find Sokka or Hei-Bai. He quickly found that holding on to it without a body was quite hard to manage and didn't allow him to enter sage mode. What he didn't know was that it made his spirit visible in the real world, so had anyone been looking they would have seen a ghostlike Naruto (not that any of them would know who it was) standing at the gate. Naruto stopped gathering the chakra and looked along the path only to see something approaching fast.
"Sokka?" He asked hopefully, though he realized that is wasn't very likely. A moment later he manages to see what looks like a ghost dragon heading towards him."That's definitely not Sokka!"
He opened his glider and took flight back into the village, but he hit the ground again a few feet away. He got up and tried to airbend the glider off the ground, but nothing happened. Aang looked down at his hands in annoyance.
"So I can't airbend or use sage mode in the spirit world!" He concluded looking back at the dragon who approached his position quickly. "And I wouldn't be able to run from it for long without them."
A moment later the dragon landed in front of him and looked down upon him.
"You don't know where Sokka is, do you?" Naruto/Aang asked, trying to figure out how to fight if the dragon attacked.
In response, the dragon bend its head down and touched Naruto's/Aang's head with one of its whiskers which caused his eyes glow with a blue fire , before he received a vision of Avatar Ruko ride on the dragon who was right in front of him. After the dragon is sure that Naruto/Aang got the message it removed its whisker.
"You're Avatar Roku's animal guide! Like Appa is to me." Naruto/Aang stated in realization "I need to save my friend and I don't know how. Is there some way for me to talk to Roku?"
The dragon just bend its neck and Aang jumps on.
"I'll be back Katara." Naruto/Aang said while looking back at the village. He then turned back to the dragon "Take me to Roku!"
After flying through the sky for some time they soon approach a volcanic island. It had a beautiful Fire Temple on it, which they entered before the dragon flew straight towards the ceiling.
"Hey, what are you doing!" Naruto/Aang yelled just before they hit the ceiling while putting an arm protectively in front of him.
However instead of crashing into the ceiling they passed through harmlessly and arrive in a secret room that only holds one statue. The dragon landed and Naruto/Aang dismounted and walked toward the statue.
"I don't understand." Naruto/Aang said as he identified the statue. "This is just a statue of Roku."
Naruto/Aang looked back at the dragon, which touched him on the temple once again. This time the vision was of a huge, flaming comet rocketing through the sky. The vision ended as the dragon broke contact.
"Is that what Roku wants to talk to me about? A comet?" Naruto/Aang asked for clarification, while glancing back at the statue "When can I talk to him?"
The dragon lowered its head in response and revealed that the sun shone through a tiny window high up in the ceiling. The shaft of light, previously blocked by the dragon, now hit the wall near Roku's right shoulder. The dragon touched Naruto/Aang again and a vision of time passing at the Fire Temple began. He was shown the temple from the outside as clouds flew by at incredible speed overhead and the sun ran its daily course in a matter of seconds. Three days past in this fashion before the vision returned to the floor of the statue's chamber focusing on two Asian written characters that are on the floor. The vision than focuses on the beam of light that enters the little window. Days past in rapid succession there as well making it clear that each day the spot where the shaft of sunlight hit the back wall gets closer to hitting the statue's face. After that the dragon breaks the connection again.
"It's a calendar, and the light will reach Roku on the solstice!" Naruto/Aang realized before turning to the dragon "So, that's when I'll be able to speak to Roku?" This got him a grunt of confirmation from the dragon "But I can't wait that long. I need to save Sokka now." He then jumps onto the dragon again and they take of again, leaving the island behind them.
Naruto/Aang and the dragon fly through the wasteland at the edge of the forest and Naruto/Aang realized that they are heading straight for a bear statue with Aangs body sitting on top of it. Naruto/Aang braced himself for impact, but he just fluently rejoined his own body as the dragon disappeared into the statue. Aang wakes up, now back in the material world. He jumped down off the statue and turned to stare in wonder at it. After looking at the bear statue, Aang opened his glider and flew back toward the village. As he returned he saw Katara looking downcast while standing on the porch of the meetinghouse. She looked away briefly but as she turned back he knew that she's seen him as a smile spread on her face and the moment he landed she rushed to hug him. Meanwhile Momo flew to him in order to perch on his shoulders.
"You're back!" Katara exclamed happily "Where's Sokka?" She added, hoping that Aang would tell her that Sokka was on his way.
"I'm not sure." Aang said, "But I may have figured out how to communicate with Hei-Bai, though I won't know until it turns up."
"Really, how?" Katara asked.
"I'll tell you later, okay?" Aang asked.
"Okay, after Sokka returns then" She agreed.
Once the sun had set Aang started gathering nature energy to make it easier to find Hei-bai. He was standing at the gate to the village to intercept it once it entered but he wasn't happy to find that it was already in the village. He quickly ran towards the building, but as he reached it the Hei-bai broke through the roof of it. It roars in triumph, releasing blue energy from its mouth. Aang made an air shell to repel the debris from the building.
"Aang, what are you doing?" Katara yelled from inside the meeting house "Run!"
Upon hearing Katara's voice Hei-bai roared and ran toward the meeting house, but Aang ran after it and jumped over its back and used air-bending to turn around in the air and touched his hand to its forehead. Trying to use the ability to mentally communicate with spirits that Ruko's dragon had used on him. His hand glowed light blue, and Aang saw a panda bear overlapping the monster. Aang jumped back to the porch of meeting house.
"You're the spirit of this forest." Aang realized "Now I understand. You're upset and angry because your home was burned down. When I saw the forest had burned I was sad and upset." While part of that sadness hadn't been related to the forest himself, some of it had been, therefore he didn't feel that it was a lie "But my friend gave me hope that the forest would grow back."
When he finished, he showed Hei-Bai the acorn that Katara gave him. The spirit smiled and Aang placed the acorn on the porch. Hei-bai picked up the acorn and transformed into its natural form, a panda, and then turned and walked away to the village gate. As the panda exited the gate a thicket of bamboo grew to man height in seconds behind it. A moment later, Sokka and a few villagers exited the thicket looking confused.
"Sokka!" Katara yelled as she ran up to hug him. The villagers followed behind her to hug their own loved ones.
"What happened?" Sokka asked in a confused tone of voice.
"You were trapped in the Spirit world for 24 hours." Katara stated "How are you feeling?" She added worriedly.
Sokka gained a pained expression "Like I seriously need to use the bathroom!" He answered while holding his crotch and moved towards the nearest place to empty his bladder.
After Sokka had finished doing his business the three of them meet in front of the village leader, surrounded by different villagers.
"Thank you, Avatar." The leader said to them formally with a happy expression "If there only were a way to repay you for what you've done."
"You could give us some supplies and some money." Sokka stated while smiling as well.
Katara wasn't happy about his choice of words and elbowed him in the side and said "Sokka" with an angry expression.
"What?" Sokka said "We need stuff." he added.
The chief bowed to them "It would be an honor to help you prepare for your journey." He stated before leaving.
Once he left Katara turned to Aang.
"I'm so proud of you, Aang." Katara said proudly while smiling at him. "You figured out what to do all on your own."
"Actually, I did have a little help." Aang said nervously "And there's something else."
"What is it?" Sokka asked.
"I need to talk to Roku and I think I've found a way to contact his spirit." Aang stated.
"That's great!" Katara said with a smile.
"Creepy, but great." Sokka added.
"There's a temple on a crescent shaped island, and if I go there on the solstice I'll be able to speak with him." Aang explained
"But, the solstice is tomorrow." Katara responded
"Yeh, and there's one more problem." Aang stated "The island is in the Fire Nation."
This got shocked and scared expressions from the two others.
A/N:
Chapter delay: I already knew at the end of the last chapter that this chapter wouldn't come as soon as the previous ones, but I had planned to upload it around Christmas or new-year, however my hard-drive broke down completely, meaning that I lost all my chapter notes because I hadn't made a safety of it. After I got a new one I was lacking in time to write, and was mostly using my other computer (where I write another story that I might upload soon).
Shinobi Naruto/Aang: It was commented that Naruto's ninja skills aren't used that often (the way I understood the review), and my answer to that is that because he spend a lot of time living Aangs life his previous abilities are rusty and his instincts are more towards using airbending. He will of cause return to using his ninja skills more often, but he is still trying to keep them a secret until he gets into a situation where he really needs them. That being said the fact is that Naruto has always been more of a taijutsu fighter, both his shadow clones and rasengan mostly support his close range fighting as well, so it isn't like he will suddenly start sprouting ninjutsu left and right.
Mai: One person asked me to add her to the harem, but that will not happen. I might not be a big Zuko fan, but those two should stay together in my opinion. In order to fit her into Aangs harem I would need to change her too much, and I like the character the way she is.
Azula: She seems to be quite popular, since more then one person has tried to get me to add her to the harem. Due to some argumentation I have changed her fate slightly, but she still isn't planned to be a part of Aangs harem for multiple reasons: She doesn't fit mentally with Naruto/Aang, and making her fit would make her OOC, something I would rather like to avoid. She also doesn't fit with the other girls in Naruto's harem, especially Katara and Suki. The other reasons for not adding her are some I will keep to myself until later in the story, because they are connected with future events.
Rasengans (thanks to Jiopaba for his input.):
These still aren't completely done yet, especially the earth rasengan seems lacking. I also still need suggestions for how the different ones should look.
Fire rasengan: Rasenenjo: When hurled leaves a huge swirling vortex of flames behind it, destroying the air along its path and sucking everything inwards in its trail before the entire path erupts into a huge explosion of flame and the point of impact is basically disintegrated like a direct hit from a Rasenshuriken, just with incredible heat that instantly sublimates everything it hits into a gas. Weakness': If it isn't hurled strongly enough its direction becomes unstable and it can start flying in random directions. It can also be rather fragile so it can explode before reaching it's target.
Water rasengan: Rasenmaki: When used it absorbs any water nearby, including from the user, once it hit something it crushes whatever is utterly, and then explodes like the Nidaime or Kisame just fired off their strongest water technique, releasing all the water it collected, including the water chakra used to create it. This would be the sort of thing which alters the entire terrain, adding like five feet of standing water until it drains away. It could wash away a whole army in a single blow. If used underwater or hurled into water, it'd hit, drill straight into the ocean or pond or lake or whatever, and then all the water in a huge area around it would start swirling and collapsing inward, creating a huge whirlpool almost instantly. Instant fleet-killer. Drag in a dozen ships in an area half a mile across and grind them into scrap. Weakness': If held to long it absorbs the liquid in the users body, making them useless, if not killing them outright. Changing the terrain might not be helpful for ones allies, making it a double edged sword, and the same is true for the whirlpool version
Earth rasengan: Rasenterra? Rasendo? Raseniwa?: Unlike the static form that most other rasengans have, this one is unstable and constantly vibrating at an incredible pace. Anything it touches has to follow it vibrations or it will grind them to dust. This means that if used on a person it turns their bones to dust and if used on the ground it creates an earthquake. It could potentially damage the person using it and if used on the ground it could potentially damage the tectonic plates, messing up the very makeup of a planet.
