So apparently I'm not alone in my love for Obito, you guys seem to want more of this and I'm happy to supply. Lets get to this.
Obito sat meditating in the small hut provided to him by the people of the settlement, it wasn't much but it was something. It was early morning and he'd just woken up only an hour before, though from the silence coming from outside he supposed he was the only one awake. This was something he was use to, he never slept much, only a few hours a night at best.
As he sat he focused his chakra on the area around him and reached out with it, it was an experiment that he'd wanted to try for a while. He felt around and at first nothing, then after a while he found what he was looking for, nature energy. After seeing just how drastically Naruto had increased in power after learning how to harness it, as well as seeing the first Hokage use it first hand, he wanted to see if he could use it as well. He began pulling the energy into himself slowly until he felt the warmth of it, he soon began rapidly pulling more in completely unaware of the effect it was having on his body, slowly he was turning to stone.
Just as the stone was enveloping his foot however the flap to his hut opened pulling him out of his meditation. "Mr. Uchiha, the elder would like to see you in the chiefs tent." A woman spoke not noticing the shocked look on his face as he looked down and saw his foot slowly returning to normal from its stone state.
"Thank you, I'll be there soon." He quickly replied as the woman left. Looking closer at the effected area he frowned. "This could prove trickier then I thought." After a moment of stretching his legs and feeling for any negatived side effects of the energy he absorbed he stood and walked out of the hut, he was mildly surprised to find the it was nearly noon. "I guess I was meditating for far longer than I intended." He mumbled noting how he let time pass by so quickly.
Obito made his way towards the tent where he had dinner with the men the night before and entered to find the elder standing by several men all holding wooden weapons and wearing what looked like leather armor. "Whats going on?" Obito asked the elder who used a red liquid from a bowl in his hand to make a cross on one of the mens forehead.
"I am blessing the men for battle." The Elder answered as he continued.
Obito was slightly surprised. "I will be fighting the beast alone, this is unnecessary. I mean no insult, but you people would only get in my way." He crossed his arms, he looked over to the youngest of the men in the tent. "You there, how old are you?"
The boy who didn't even look like he was eighteen yet stepped forward. "Fifteen winters, but I'm strong. I can hold my spear as well as anyone."
The elder turned to Obito. "These men all volunteered to lead you to the dark gods lair and assist you in your battle. You will not be able to get through the dark gods minions alone, these men are willing to give their lives for this cause if it will help their families. Tora lost his father in the latest attack by the beasts and is now the head of his family, it is his choice to fight."
Obito frowned. "How many of you are trained in combat? Have any of you ever fought in a battle like this before?" He asked waiting for someone to speak, after several seconds of silence he had his answer. "I understand your desire to help and protect your families, but you will only die if you follow me into battle. None of you will be around to provide and protect your families once this is all over. Don't throw your lives away, I can do this alone."
Obito could see the faces of the men shift as they thought of leaving their families alone if they were to die. "The dark god took my fathers life, I will not stand by as a stranger fights this battle for us. I am a man and I will fight by your side!" Tora shouted clearly angry.
Shaking his head and sighing Obito looked the boy in the eyes. "Very well, I will allow you to come along on one condition."
"What is it?"
Obito gestured for him to follow as he walked out of the tent, the men all followed as he walked to the center of the settlement. Once there Obito dragged his foot along the ground creating a small circle about two and a half feet wide, just large enough for him to stand within it. "If you can force to set even a single toe out of this circle, I'll take you with me. This goes for anyone else who wish to join me in battle."
Tora raised his wooden spear and charged Obito, just as the tip of the spear was about to hit him however he swatted it aside and grabbed Tora's arm pulling him towards him. He smacked the boy on the side of his face with the back of his right hand hard enough to send him to the ground and slide several feet. "Come on kid, get up. That wasn't even a tap."
Tora wobbled slightly as he lifted himself to his feet and grabbed his spear off the ground. Again the boy charged but was again met with Obito's backhand across his face. Tora's face was beginning to swell and bruise after the seventh time, his nose was bleeding terribly and tears were streaming down his face. Tora forced himself to his feet again and began wobbling towards Obito with his fists clench, his spear long since taken and tossed away by Obito. After stumbling towards Obito slowly he lifted his fist and threw a punch that connected with Obito's nose, however the shinobi didn't budge a millimeter. Grabbing Tora's wrist Obito pulled the boy closer again.
"Boy, I understand your pain and your desire for revenge, but you simply aren't strong enough to do anything. Give up." Obito whispered to the boy.
Tora spat a glob of blood onto the ground. "Never." Obito sighed.
Obito tossed the boy several feet away and closed his eyes, when he reopened them they were both glowing slightly and held his Mangekyou Sharingan. "Stand up!" He barked at the boy who was struggling to his feet. As Tora stood back up Obito pulsed his chakra and began giving off a light blue aura, slowly a light blue skeleton began forming around him causing many of the people who were watching to scream and run while others stood in a terrified awe as the Susanoo began to form.
The Susanoo stopped forming when the skull was complete. "This is but a fraction of what I can feel from the Dark God, are you truly foolish enough to continue this fight?!" Obito's voice boomed, Tora stood in awe for several more moments before falling to his knees and weeping. Obito watched this and soon dismissed his Susanoo. "Do not throw your life away boy, your far to young to die today." He spoke in a slightly softer tone. Obito walked over towards the elder who remained where there crowd once was.
"Thank you for your hospitality and your offer for assistance. I will return once the beast is dead." With those words Obito disappeared with the body flicker and began heading towards the source of the evil.
Hours later
Obito stood at the edge of a massive crater nearly two miles wide looking down towards the center. At first glance it looked like a giant lake of black water with a large black island at the center, but upon closer inspection he could see the it was in fact several hundred thousand black beasts surrounding a single massive abomination that appeared to be leaking black liquid. When the liquid hit the ground another beast would crawl out of the puddles.
"The old man said that these things were attracted to negative emotions, time to get their attention." Activating both his rinnegan and sharingan, Obito sent a massive wave of killing intent across the entire area. Almost in unison, thousands of pairs of glowing red eyes turned to look towards him. Obito took a step forward into the crater, as he slowly began walking towards the horde of monsters a symphony of growls and roar erupted from the horde.
Obito slowly began picking up the pace as the monster also began their charge, by the time Obito was sprinting the beasts were also barreling towards him in a tsunami of black fur and white masks. "Shadow Clone Jutsu!" Obito flipped through several hand signs and called forth around thirty clones before making a chakra rod extend out of his palm.
The moment the two groups collided the clones began slaughtering the beasts left and right, chunks of the beasts were flying through the air and roars of agony shook the ground. The battle lasted hours as Obito cut his way through hundreds of the black beasts, however after the sun had long since fallen and stars filled the sky he stood before his target.
He panted lightly as his remaining clones continued killing the smaller monsters. The dark god was huge, easily the size of one of the bijuu back in his world, thick black scales covered it's hide and Obito could see several spines across it's back. It's body expanded and contracted slowly as it breathed in a way that let Obito know that it was in fact asleep. "Arrogant beast." He mumbled before stepping forward and placing his hand against it's side. "Time to wake up, ALMIGHTY PUSH!"
His chakra pulsed and an unstoppable force comparable to the one that Nagato used to destroy Konoha expanded from all around him obliterating the smaller beasts and sending the dark god flying away and slamming into the edge of the crater where it began uprooting trees as into continued to slide across the ground. Obito fell to his knees panting heavily from the massive chakra drain of the attack, even though he could feel how massive his chakra reserves had become and remained from his brief time as the ten tails host, he still wasn't quite use to using such powerful jutsu. "I'm gonna have to work on that as well."
Regaining his composure he stood and began walking towards where the beast had stopped. He could here roars of rage coming from the the beast as it got to its feet and raised it's head, all seven. The beast spread it's wings wide and threw it's heads back and let out a ground shaking roar. "Good, your awake. Lets begin then."
Obito summoned forth his Susanoo again into it's perfect state and stood before the beast matching it's size. Tilting his hands Obito created a pair of energy blades in the hands of the Susanoo, the beast flapped it's wings creating a gust of wind powerful enough to tear up the remaining trees around it and lifted it's self into the air. Obito called forth a pair of wings of his own and followed it into the sky. (A/N I just wanna take a moment to say that I can't even begin to understand how the sharingan went from being able to copy jutsu in season 1 to being able to create a flying gundam thing as well as nearly anything else you could possibly think of by the end of the series. It's beyond overpowered at this point, now it's just fucking ridiculous, oh well back to using it though.)
Elsewhere
The elder of the settlement stood at the edge of the crater watching in silent awe as the being they considered to be all powerful and absolute evil fought against their unknown savior in the sky above. The men around him all fell to their knees in a similar state of speechlessness.
"Is this what the power of a god looks like?" He heard from next to him, Tora stood beside him staring up with bandages covering his face.
The elder remained silent as he watched the battle, winds blew his long hair back with every shock wave caused by their clashes. "Everyone listen up!" He shouted getting the attention of the men. "I want everyone of you to watch carefully and remember every detail you can about what we are seeing. Win or lose, this is a battle that must be remembered and relayed to our children, and their children. What happens here today needs to be remembered forever because it's consequences will surely reach the very ends of time as well!"
The men all silently accepted the order without ever taking their eyes off the spectacle above them. "OBITO UCHIHA! FIGHT, SURVIVE! OUR HOPES ARE ALL WITH YOU NOW, END THIS NIGHTMARES REIGN!"
With Obito
The beast fired a blast of energy from it's heads which Obito blocked blocked with his Susanoo's blades before countering with a wave of energy of his own. The beast dived under the attack and charged towards Obito slamming itself into the Susanoo cracking the armor slightly.
Obtio brought the blade in his right hand down upon one of the beasts head cleaving it off and causing it to fall to the earth bellow. The beast roared in agony and rage as it's blasted another wave of black energy into the Susanoo's face creating a hole in it's armor. "Miserable lizard!" Obito shouted as he jumped out of his spot within the Susanoo sporting several burns across his body from the attack.
Flipping through several hand seals Obito shouted. "Wooden Dragon Coil!" A massive wooden shot up from the ground far below the beast and him. The wooden construct sunk it's teeth into the Dark gods hide and proceeded to wrap itself around the beast and restraining it's wings causing it to fall towards the earth. Obito jumped off of the beast and landed a safe distance away as the massive creature slammed into the ground with incredible force.
Obito panted as he looked towards the battered beast who was picking itself up. Obito wiped the blood from his eye that had begun leaking from his use of the Susanoo. "You really are almost as strong as the juubi, which means I doubt I can kill you. I can also tell just by looking at you with these eyes that your a being of corrupted nature energy, so even if I did kill you it wouldn't be permanent." Obito closed his eyes and took a deep breath. "I'm gonna have to take a page out of the sages book with this, and a little of my own mixed in." Obito began flipping through several hand seals. "Great Wooden Prison!" Dozens of long pieces of wood shot out of the ground around the beast and wrapped around it's struggling body.
When the beast was sufficiently ensnared Obito called forth his Susanoo again. "This is where your terror ends." Raising his blades he quickly brought them down in a flurry of swipes cutting the beast into six pieces, one for each head. The wood bindings pulled the writhing pieces apart and away from each other. "PLANETARY DEVASTATION!"
Rocks from beneath the ground began slowly rising up and encasing each of the six portions of the body and creating a large round ball, after several seconds six giant round stone orbs floated several meters off the ground. Obito flipped through more hand signs. "Multi Wooden Binding Sphere!" Wood shot up from the ground and surrounded each of the six orbs in a thick outer casing of wood. "Shadow Clone Jutsu. I've never actually used this technique, but I watched Minato-sensei used it with my sharingan. Be honored to be sealed by his jutsu."
Six Obito's appeared and each ran to one of the orbs where they bit their thumbs and placed their bleeding hands upon the wooden orbs and in unison shout. "Eight Trigrams Seal!" Black symbols spread across the surface of the wood encasings.
"And for the last touch." Obito spoke through heavy breaths. The Susanoo began rapidly rising into the shy with the orbs following, he continued rising higher and higher until he was far above the clouds. He looked up to the shattered moon as he continued rising for several minutes before stopping. Looking down he could see the curvature of the earth easily, he could see the oceans over a hundred miles away.
The six orbs surrounded him in a circle, focusing as much chakra as he could without dispelling his Susanoo he held his hands out. "Almighty Push." Each of the six orbs shot away at extreme speeds in different directions. Obito watched as each fell to a different corner of the planet, some thousands of miles from each other. "May you remain scattered for eternity, monster."
Obito began his decent towards the earth below, after several minutes Obito's vision began to cloud slightly. As he was nearing the cloud layer he could feel his Susanoo fading as well as his consciousness. He was exhausted, beyond exhausted. He was well past the point of forcing himself to keep going through sheer will. Upon reaching the clouds his Susanoo completely faded and everything went black.
I feel that is a good spot to stop. I'll admit I had a very hard time writing this battle, I also know some of you are like 'Obito doesn't have the chakra to pull all that off.' and my reply to that is this. Sasuke was able to use planetary devastation to capture ALL NINE of the tailed beasts AND fight Naruto with his Susanoo AFTER fighting Madara and Kaguya during the war. Compared to that, this is nothing. I hope you all liked it, tell me what you think in the reviews.
