The first of the Sharingan's powers is being able to see the flow of chakra. The Sharingan can tell if a person is under a genjutsu because the person's chakra flow would be irregular.

The Sharingan's second-most prominent ability grants the user an incredible clarity of perception, allowing them to easily recognize genjutsu and different forms of chakra, though not to the same extent as the Byakugan. This also allows the user to pick up on subtle details, enabling them to read lip movements or mimic something like pencil movements. As the Sharingan evolves, gaining more tomoe seals, this ability extends to being able to track fast-moving objects before finally giving some amount of predictive capabilities to the user. However, even though the user may be able to see an attack or know it is coming, their body may not have time to react.

The Sharingan's third and most well-known ability is that it grants the user the ability to memorize any technique that he or she witnesses, apart from other kekkei genkai techniques. The user can memorize ninjutsu, genjutsu, and taijutsu with near perfect accuracy, allowing the user to use the techniques as their own, or even modify them to create their own new techniques. In order to reproduce a copied jutsu, however, one must have the necessary skill or ability to perform them. In addition to physical skill and kekkei genkai techniques, the Sharingan cannot reproduce jutsu dependent on other factors, such as summons that the user has not signed a contract with.

The Sharingan's final commonly-used ability is capable of inducing a unique brand of hypnosis that involves suggesting actions and thoughts to the opponent through genjutsu cast by simple eye contact. More advanced Sharingan users can take the hypnosis ability even further to the point where a powerful summons or even Bijuu’s may be controlled. When this was used against summons and the Bijuu’s their eyes took on the tomoe pattern of the users' Sharingan while under hypnotic influence.

The hypnotic ability coupled with the other aspects of the Sharingan, can make the user appear as if they can "see the future". First, the user must perfectly mimic every move their opponent makes and possibly their thoughts and words through careful observation. Then, they suggest an action to the opponent such as hand seals for a jutsu that the opponent and Sharingan user already know and copy that. With these things done, the user can complete the action even before the opponent does, possibly using the Sharingan's genjutsu to confuse or delay them. As with other genjutsu, genjutsu cast by the Sharingan are capable of putting an opponent to sleep, inducing paralysis, replaying memories to someone else, or creating various illusions to deceive someone. The potency of the Sharingan's illusion is dependent on the user's knowledge and skill with implementing genjutsu.

Although the Sharingan consumes the user's chakra while active, the chakra levels that the user must exert is so insignificant that they can keep it active constantly. However, when a Sharingan is transplanted to a non-Uchiha, the chakra drain is significant, leading them to cover it up when not in use, to stop the drain.

The Mangekyō Sharingan gives the user access to several powerful techniques, including the powerful fire jutsu Amaterasu and the almost unbreakable genjutsu Tsukuyomi. The Mangekyō Sharingan erodes the eyesight of its users, eventually causing blindness, which can be prevented by obtaining another pair of Mangekyō Sharingan from a sibling. The new Sharingan is dubbed the Eternal Mangekyō Sharingan

The Uchiha clan descended from the elder of the two sons of the Sage of the Six Paths. The elder brother inherited the Sage's "eyes", powerful chakra and spiritual abilities. When it came time for the Sage to choose a successor, he questioned the two on what course of action they would follow to bring order to the world. The elder believed that might was the way to bring peace, while the younger believed love was the way. The Sage favoured the ideal of the younger brother, and therefore designated the younger as his successor, causing the elder to be filled with jealousy and hatefulness. From the younger son descended the Senju clan who would be the eternal rivals of the Uchiha.

Before the founding of the ninja villages, the Uchiha were one of the many mercenary clans for hire. Because of their Sharingan, the Uchiha clan came to be known as one of the two strongest clans, the other being the Senju clan. As time passed the Uchiha grew stronger, conquering whatever clans they came upon, such that, whenever the Uchiha clan was hired for a job, the opposing side would hire the Senju, and vice versa.

The Senju clan, grew tired of the endless fighting, and approached the Uchiha clan with a peace treaty. The leader at that time feared that an alliance would lead the Uchiha to ruin, but his clan disagreed, and he was forced to accept. The two clans came together to form Kusamugakure, with the leader of the Senju Clan, being selected as kage. They turned their backs on those who opposed the overall decision, and they defected. Now the Uchiha clan slowly regained their influence in peacetime but what happens next will depend on the generations to come

Kazu was born on Nov 14, he had both parents who was raising him well, until one day he found his father by the porch, wanting to speak with him he was really a kind hearted kid who always stayed positive no matter how tough it got, as he reached to his father before speaking to him, his father has went away for 3 years on a mission. As the years pass training vigorously with his gradnfather to harnest his first water element soon his father has returned, with a bright smile Kazu hugged him happy for him returning home safely.

Kazu was now a member of the Jungle village, infact he was a genin and coming squad. His life was pretty much excellent until he got Transfered from the Kazu gathered his essential and was accompanied by two other jounin on this road, the travel was supposed to be easy, but something wasn't right......they was unexpectedly attacked by the akatsuki members , Kazu was ready to fight but with just his 3 techniques just wasnt enough, as the Jounins were slain Kazu pulled his hood up covering his face he planted his feet to the ground making dust tracks disappearing from them to escape. Kaz lost them soon enough, then he continue to the Hurricane where he stands in front of the gate ready to go in.

For his great day to start off he became a great ninja in the past even though he wanted to be being welcomed into the village, even before he could get there he met a woman named Yuki who he fell in loved with. The spark just clicked between them he doesn't know how but he was truly happy. Meeting up with the Hurricane Kage he took on a few missions and whatnot and was gonna be trained. Being so psyched it ended it as a failure and ended him up in a hospital. Waking up soon he was different very different it was cheated out of the training almost dying to the point. Taking on a new dark attitude he was ready and training to take on that blasted Kage again almost wanting to kill him.After a while he was trained by a man named Kamui taking Kazu to mount Myria to train him like never before facing a darker version of himself. It was a bust and he learned nothing since it was a complete waste of time.

Still dark and in mourning over his loss his mind was so troubled, heading to the Selena Forest he crossed paths with a certain redhead by the name of Kallen Shey, who kissed him not before long he met up with her partner Mika. They were suspicious looking and as it turns out they were part of a group called Yugure. He was determined to find out who they were without even thinking he was sought out by the two women and was brought back to their only to meet up with the leader. He never really knew his name but he was a tough S.O.B. After a few days he went back and forth to see how Yuki was doing as she was missing him dearly worrying about his safety, Kazu gave her the benefit of the doubt to marry her when he gets back. Though a certain event happened when he met a certain woman he didn't know who she was till they walked past each other and stared into each other's eyes with feeling of bloodlust and the intent to kill. His Sharingan meeting with the woman's Mangekyou being both Uchiha they stood down then exchanged names and a little words to each other and walked away both defecting the Yugure going their separate ways.

After two years he was fine and dandy almost to say he was getting back to his old self. He was doing great seeing he had a chance to join the village he sought out to return to. Thought he was rudely interrupted by the Kage by him screaming at him. He was here to make amends but as soon he heard Yuki was with the kage he just shook his head seeing it coming from a mile away. Meeting up with Yuki with a rotten ass attitude because he left. He apologized till he heard the two talking behind his back. Those words right there rectified his whole personality he was ready to shut him up once and for all. After a quick but extreme match he was ready to kill, but he was given a choice join or be killed. He joined back to the Shippu village and he really wanted to kill and beat those two down but he knows that won't solve anything. He was still in his dark place of his heart, feeling it surging through his heart made him wanna fight more and more. After that he grew relentless.

Now that a few years have past he walked out the village gates of Shippu once more making his way out. He was ready to leave but first something was telling him to get to the Moon village something was telling him to go there, as if someone is waiting for him. Rushing through the night he was heading his way off the coastline and heading to Tsuki village he had to get there, to see what is making him want to go there so bad. Being the troublemaker he was before it wasn't long till his eyes throbbed and the lust to make someone do his bidding, though it seemed that his missin-nin status was already notice in such a small amount of time. Quickly making work of the ANBU MOON SQUAD, he escaped with his life with ease. His life was completely unremarkable to all ninja in such a young age. He flew under the radar for for a total of 2 years, taking the easy way and doing the bare minimum to continue moving forward without causing a scene. While others around him moved through the villages he came into, he was suspicious. He remained being a Sp. Jounin

It wasn’t until he was under constant barrage of insults that he started trying to be more than he was. eavesdropping on few conversations about his disgrace to his clan and the dis-respectfulness towards him. He became the epicenter of all the foul play by the constant bickering. He began taking as many high risk motives as possible even as far as creating a team as for himself, quickly being taken note of with potential strength and high risk tactics. Over the next few months or so his abilities has grown along with his sharingan, as a S Ranked Missing Nin in the bingo book he was soon known as highly armed and dangerous which he was considering he doesn't know much jutsu. Training in the outskirts of the Mirage country and onto a next. He was introduced into a place where was able to trained, only the strongest willed combatants were allowed. And even if you were, and you failed you would have accepted your fate and died. Mount Ether which was the biggest forest he been to. Almost much as the forest of death, except the gravity was much heavier and air was so thin that single breath lead him to almost choking. No so used to it he had fallen to it, driving him to his knees as strangers ambushed them the toughest of the tough, never seen them fight like so aggressively and relentlessly to them he was just a plain old rookie, a fish out of the water. Even his sharingan was no matched soon, he had to do this clinging to his very life.

On the verge of death every day, no medical supplies, nothing but his sword, jutsu and his cloak. Injuring himself months passing by as he meditates and see how he could survive like this. Never pushing himself pass his limits like this, lifting some of his old feelings of his dark could looming over his head. He was able to come one with himself, with his cloak ripped and tying over his several wounds as looking as if he was a in a kimono. He became the savage of Mount Ether, taking on every oppenent that came his way. When the chance to kill them was in his grasp, he would be truly be a savage if he did. But that wouldn't bring his life back, he has even killed one of his own comrades in Shippu and for what...cause he was angry at his Kage and his stolen fiance cause he has no self control of the senseless killing. "They deserved to die" was the last words he had, and he told himself he wouldn't succumb to being the true descendant of Madara. Escaping the situation before he did something he regret, the actually first time of him walking away for something he always did. Looking at his bruised, bloodied hands he soon realized his hands were tainted with the lives he took. Straightening himself out, training on his own for days on in getting stronger each day. It was time to push himself through more and more stress. Training learning new techniques along with a new nature element to his arsenal. Even at his teenager age like status he was getting stronger even those would not believe back in Shippu or the land of Mirage. Guessing dealing with his bare feet on the ground moving in such a fast pace, his speed was high along with his dexterity. Acheviving perfect balance in his sword fighting and phyiscal attributes. Fighting just to breathe to survive. Before he knew it he was discovering more main parts he discovered a village nearby nothing big as any normal village he gone to. Seeing this was a town filled with dangerous assassins and such he was ready for anything. Gathering supplies looking like a new person and refresh he grown accustomed to the area, soon he come to realized he would have to return to his own country. Needless to say tthat this place has changed him also taught him to kill if necessary, while still having that blood thristy side part of his soul. Healing himself and getting himself cleaned with a new set of gear. A ragged cloak, he began to run back and continue his training on the island learning new things of what his body could do.

He was now alone again, he wandered from plain to plain never staying in one place for to long and never being stupid enough to leave a trail to his location. After a few months of traveling Kazu ducked into a cave to get out of raiding commotion and while exploring it found a small box. When he opened it he found a scroll, He could tell it was old so he opened it carefully but what was inside was so amazing he almost dropped it. It was step by step instructions for Secret Dragon Attacks with all Nature Affinities.
It took him 3 days straight to learn the techs with the natures he had., But when he had he could tell this move was one of the most powerful jutsu he had ever had. While he was traveling he had been training in the forest like crazy, training like a beast to the point of him sweating, gasping for hair getting his scared body to the point of its highest peak. Mastering his new element of Earth he was in the clear. But at what cost the forest was changing burning around by the local militia nukenin raids along the corners of Mount Ether. He stayed hidden till the forest was bruned to the ground, under the rubble and ashes he jumps out of it. Smokey and filled with charred debris. He looked around seeing it was time to get some water, get out of there. Heading to the ocean he looked around seeing if he was able walk back to his country of Mirage. Making it he was in the clear to get back, though he stopped on his way the Village of Ice, Hyouga the area where he met alot of worthy allies but again right on the outskirts by the glacier covered area. Perfect place to train under another set of harsh conditions. Meditating on the coldest point of the land, training his skin, strengthening the body he was able to withstand it even with the climate change. With new highly attained abilities he was able to set aside his old self and reborn to a new mindset with better goals he was setting, maybe he could get his life together maybe get his comrades back on his side. And maybe just being something else besides a Uchiha full of hatred and rage due to traumatic events. Standing on his own two, he was training with his kusanagi sword displaying his swordsmanship the best he could. Displaying his skills along the waves of ice, the frostbitten razor wind and even quaking Ice beneath him. It wasn't long till he had to stop and travel again. Seeing nin from all villages from his era surround him in the crossroads he was angry then it was time for that part of his soul to come out. All that pent anger swelling up inside him made him nuts, taking no prisoners he drew his sword then slashed through them, with his highly advanced skills. Non-stopping strategic rushing with nothing but brute force and such speed. Along with his jutsu he was unstoppable, even such as seeing a water jutsu performed by them and he instantly copied it and washed them out to the frozen sea, leaving them. As bodies in his wake of where ever he went he was too powerful though his body wasn't used to using so much chakra. Passing out in the wasteland panting as he was trying to fix himself and trying his best not to be vulnerable in this weak state. Staggering he made himself into a cave hugging his kusanagi, his fathers sword in his arms next to his knees. Falling into a light slumber as if anyone dare to oppose him. In his sleep he grew tired, flashing back to his parents and the death of the blind Uchiha elder, then flashes of his past life 2 years ago, fighting Kages, with comrades and even past relationships. The nightmares grew stronger and stronger making him awake in a cold sweat that aches his head to a point where he had to get up and get some fresh air. Driving his thoughts in a pile of aggrivated mush. Enduring it the best way he could by relaxing himself and standing or taking a nice stroll by himself on the wasteland. Continuing his journey to find more opponents to fight and search for, he stumbles on another task force but this time by the Hyouga followed by the Tsuki...seems like he was the one for popularity of appearances. Confident on how it wasn't gonna turn out like last time, he read them closely with his crimson doujutsu and took them all down, more skilled than he was before like last time. It was time to end this constant ambushes, holding a conference and hypnotizing few contract ninjas, using their animals to send notes to the Kage to hold a conference. No fighting, bickering, just a discussion on getting the monkeys off his back.As the conference of the Kages was held in Shippu, some how it all started in the harbor where the last one had occured. Chatting down for hours to explain himself somehow, some way in the most upmost confusion to him the whole way. Kages was trying to kidnap and detain him for questioning about his ties to the evil Yugure organization and his ties to the bijuu. Seeing that his eyes was narrow by this accusations of his presence. He wasn't with the Yugure and yet to see any bijuu, only he knew was the leader and more harmful plans from them. Agreeing to accepting their terms, he soon turned himself in as he thrown into Hel's Playground in the storm village. As the Kages predicted the Yugure next and final attack he was trapped, There was no way to help them and it was his predictions that was very helpful to the Kages. Though pain through his head was throbbing as if his blood was awakened by the Bijuu, what was the connection to it and his bloodline and why? The question loomed in his head and through his heart. Refusing to give in and by his amazing abilities, he bursted out of jail. Heading to the top of the prison then heading north, he made it out and now the hard part began. Heading to battle and stopped by villages higher ups from continuing his path to battle to assist anyone who needed it. Trying to make his way he was overwhelmed by the combined forces of the villages and ninja. Without stopping he felt like it was a trap and he was ready to help them no matter what the cost. The Tailed beasts was running while he was constantly wasting energy and time to get through. Standing down as seeing they didn't need his help, maybe it was time to stand down and let the real ninjas do their job since he haven't felt he became one but more of a troublemaker. Enraged by being a stepping stone of insults he turned his back and walked away. Dashing in the opposite direction in the nearby village, he needed to get back in the battlefield. Heading to the Shippu sneaking in cause he wasn't allowed and his life depended on it. Every defense in the village was strong enough to surpassed him, doing this quietly and heading to the Shippu's kage office he found a cloak ANBU, who saw him. Baiting him in he immediately capture him in a quick hypnotism trick of his sharingan. Knocking him out from behind, dragging him into the office then switch attires. Now in the best of the best classic ANBU gear, he puts on the mask and cloak making way to the battlefield. Slipping through the battlefield with ease it was not doubt or choice in his right mind that he was trying to make things right but the tiny voice in his head was telling to step aside and let them handle it, hearing that statment ringing through his ears along with the explosions he came to realize; Can he really let them handle it, step to the side and wait for the outcome of what or whether the Kages or Bijuu run wild victorious? No he couldn't in a stalement between the destructive forces he jumped high then used one of his Secret Hidden Techniques. Pushing back he revealed himself in his acquired anbu gear he stole or so called:"borrowed" as he says. Now that the Kage was here alongside with them he was able to keep up. The battle was intense and so unpredictable not even his Sharingan couldn't keep up. Too many things happening at one time, he was way out of his league but he was willing to rise up and do what he can. Gathering the Kage together as he puts his hands together with his cloak in a squating position. Telling them he can try to seal them back into the bodies, though it would take a heck of alot of handsigns and alot of chakra. Gathering from the battle he was able to seal half their power into each one of the Kage, passing out from shear exhaustion he was on the verge of death from his charka level reaching absolute zero. His ears ringing and everything going so dim he could barely see anything through the eyes in the blurry state that they were in. Still weak, he heard the battle still going on seemes as if he was moved out of the crossfire, mad at himself. The Kage had some power to it but to what extent it drove him mad within his thoughts cause he couldn't pull his weight, his very own trying his very best. Giving the amount of time the kage left before their extra little boost of their sort of 'bijuu' energies. The seal won't hold forever on them, pulling himself together trying his best to rise over his extreme fatigue. He was out of it and his body ached with such agony that even channeling a spark of chakra had his body churn. A unexpected turn was coming taking form a Bijuu chakra blast so called the Tailed beast bomb took place flying over in the middle of the battlefield, far from it he noticed the force was coming and it was strong. As if a nuke was set off, he was pushed high in the air with ease due to his weak body without any endure, he was completely unconscience flying across the sea and landing in the water with a splash, injuring him even futher. Hanging on debris from his high flying traveling, he was out for hours on end. Soon he washed on the Onozuka River shore, rising slowly back to stand still weakened he looked around then saw the damage, village was destroyed, bodies, buildings and even the innocent was reduced to rubble and scorned. Panting for his breath to be captured he stood up straight stumbling to his old house, its been so long since he returned to his old home where he resided since he was a pure genin, he was so built on rage and hate that it was plain ridiculous now that he thinks about it. Him being so angry and for what he couldn't beat the crap out of his own Kage. Rivaling with his own superior, groaning he rested seeing the bijuu tore through here like a bat out of hell. Soon he made his way to the destroyed shop to replenish his energy. Savaging some food pills and chakra pills he was ready to face them off. Heading out the hurricane vilage it was only a matter of time before a loud boom was erupted again. He was scared no doubt in his mind, he couldn't he knew what was going to happen but he couldn't fathom on whether he would lie or not. The sounds of the battlefield blaring in the opposite direction, it wasn't in Shippu anymore. It was as if it was by Hyouga and the Storm villages. With his anbu gear damaged and his body still throbbing in pain a bit, he rushed forward as quickly as possible. Traveling for a hours running and dashing to the area, it took him a while before he arrived as he did he couldn't believe it, the battle seemed to calm down in a way where it was. Battle was over it was done, but at what cost though. Seemingly it seems the bijuu had escaped and everything was just destroyed even the 5 Kages, they didn't make it. Everyone dead as a door nail, he didn't want this to happen. And soon he was back to square one. Back to nothing and for what to prove that he tries his best to do the best of his ability to help others. He failed completely, blaming himself made him drop to his knees and punch the ground out of anger. Cursing himself he made his way away again, no home to go to. It took hours of him burying the bodies in the warzone. Thousands of swords impaling the ground as a gravestone of those who sacrificed their lives for the sake of their villages. A heroic deed in vain.Back on his quest to find his purpose, after a couple of days he was soon finding himself back in the shippu village. Survivors of the destruction rebuilded the village good as new along with his help as a mysterious stranger.

Few days past by he was in the graveyard on where his clan members and parents were buried, soon he was founded out. Someone did and it wasn't good for him, last thing he needed to act so savagely in battle in the graveyard of his home village. But all of that settle down when he saw her; Komakai...the Uchiha he met during his days as the member of the Yugure organization. He doesn't know what it meant but for some reason she was so happy, telling me how much she was glad to see him alive which was odd due to the demeanor she used to have. No scowl, silent of the words, or even the bloodthirsty feeling when he got close. As they sure a soft embrace, she took lead and gave him such a unexpected loving kiss. From out of nowhere she want and gave him the choice and the look of affection offering something no man could ever turn down. "Come back to the village, please be with me and stay by my side." Those words ringed off in his ears letting his heart skip a beat by those words alone. Discovering the new feelings opening up inside his heart he didn't know what caused it, was their meeting of their crismon eyes planned this as love at first sight or was this destined to be? Questions flooded his mind by was all washed away by her more assertive approach jump on top of him with that bloodthirsty trademark smirk of her along with a kiss. As that event went by he was in the village after a few adventures with his now new lover Koma, he discovered that he had a adopted daughter now that he had no clue about. Smiling and seeing his life growing to be more normal and violent free, then soon after a long year mission he came back and both Komakai and thier daughter was gone. Leaving without a word made him worried wondering if anything happened while he was gone. Hurt deeply to his core, he needed to do something to take the pain away. Thinking about it, he wasn't needed anymore since her disappearance. Going on a journey to talk to one of the allied village, Hyouga traveling there to see if they knew what to do with Komakai as the Kage and she was nowhere to be found. As soon he arrived at the gate, a arrow struck his arm cutting it, injured to a point where he fell down. More arrows came by then he rolled out the way, wondering what the hell his going on. Running away dashing holding his arm, he headed to the outskirts where the glaciers were. Heading to the different direction of the village to get in trying his best. Seeing a giagantic wall, seems like it was the thickest strudy wall he had ever seen sliding down the icy road. Banging on it demanding to gain entry to the village to talk of the kage. Peak on his behalf of Koma since she was closest person he had in a while but of in his life things never go the way he wanted, it always gone down south like a bat outta hell. Though this is not what he expected to happen being attacked by the Ice village, by arrows for pete sake. Trying to think and swiftly react at the same time, it was getting difficult to evade these attacks. Certainly having the numbers overwhelming by people; too many to one. He had to get out of here, putting his hands together along with his sharingan. Before anything could happen, Ice spikes and frost overcame the entire area, before he knew it his feet was encased, with quick thinking with blazing speed of his signature clan jutsu, he ups the ante by making the most powerful it ever been. With one fireball jutsu, so big he poured all his chakra into the white blazing flame. Never seen his technique evolve so quickly he truly believes Fire is in his favor. Everything dripping and melt, giving off a cool breeze. Another squad of Hyouga ninjas came for him, running back holding his injured arm running to shippu. He had to go he was thin ice in the Hyouga zone. Last thing he needed was to get iced by the strict staff of the hyouga. Traveling though the underground caverns feeling so weak and stiff. Suffering from blood loss, he still try to make his way to the hurricane village. Heading through the silent forest, and since Koma was missing the ninja had no jurisdiction or barrier on coming onto the land of the Shippu. Angry that he brought danger upon his missing lover's village, he was in charge but he was not well known and alot of people didn't know who he was. Hiding upon the tress within the Sleeping Forest to lay low and heal his injuries, or treat them at least. Especially his arm, groaning and limp from the throbbing pain driving him nuts. His vision getting blurry and somewhat, he takes his coat off then tosses it in the wind. Giving away his position he grabbed a kunai in between his teeth, piercing the skin on his thumb, then did a total of 10 handseals performing the ultimate sealing technique, one time use only as a trump card. Ending it in a dog handseal, japanese markings swirled and swimmed down on his skin and even his face, wrapping a paper bomb in the kunai slamming it to the ground. He placed his hands on his mid section as the earth moved and covered him completely in a steel tight coffin. The Self Sealing technique that seals one self for a seem of a eternity, like being in earth moving cryosleep. Buried deep in the ground in his earth sealed coffin, right under the blast radius. After 50 years his coffin was getting old and the blast soft sanded area was covered in grass as he was never found or captured. But finally a fist shoot up from the ground, as a sign making his return; it... has begun.
