Ryun Uchiha

Ryun Uchiha (うちはリュン, Uchiha Ryun) is a legendary shinobi, one of the last surviving Uchiha clan members, who became the new leader of the Uchiha clan, having succeeded the position from his ancestor, Madara Uchiha, after the clan was restored. He is also the First Yamakage (初代山影, Shodai Yamakage) and the founder of Yamagakure. He, along with Seireitou Hyūga, Echo Uchiha, and Hikaru Kurosaki are all recognized as "the four Yonkō".

Early life
Ryun Uchiha was born under unusual circumstances; the bastard child of a kidnapped Uchiha soldier and an unknown Kirigakure seductress, during the Second Shinobi World War, Ryun grew up without knowing the loving gaze of a father, or the tender care of a mother — and he was only the first of many born out of this plot. According to Ryun, he was the oldest of six brothers, though he took partiality to the youngest of the six, Tora Uchiha. Shortly after he turned six years old,, the Fourth Mizukage, took hold of Kirigakure, and was subsequently taken control of by the machinations of , turning the village into the.

His reign brought about new persecution on all of those who possessed kekkei genkai, including the newly acquired Uchiha members, which Kirigakure had previously bred to obtain the Sharingan for themselves. Ryun pleaded to his father to do something, but the man had become broken by lust and torture, and thus, Ryun gathered up his siblings and fled the village, hoping to make a better life for them elsewhere. The Land of Water, however, would prove to be an almost constant challenge for them during the years in which they would roam the countryside. A combination of near constant hunting from Kirigakure officials, as well as the harsh weather, and even more monstrous fauna, kept the Uchiha children in constant fear. As the oldest and more powerful of them, Ryun became the leader; a position he would regret in his later life.

Over the next few years, Ryun and his rogue siblings fought off starvation, sickness, and more fearsome opponents, such as the native which prowled the rivers and streams of the Land of Water. The group usually resorted to living in caves, moving every other week to avoid detection by the country's shinobi. During one such outing, in order to cross a bridge to the second island in the Land of Water, Ryun was confronted by a tough obstacle; a Kirigakure supply caravan that would no doubt see them if something wasn't done. Despite the gnawing feeling of regret, Ryun ordered the oldest brother (after him) to distract the shinobi, while he secured their brothers' safety. Doing as he was told, the older brother caused a distraction, allowing Ryun and the other five Uchiha siblings to sneak passed the caravan, but was subsequently killed in the process. Despite his deep grief, Ryun decided to kill his feelings, allowing him to make tough decisions for the group — though Tora seemed to be the only one he could not sacrifice in such a manner. In the weeks following this, with Ryun now eight years old, Kirigakure erupted in yet another civil war, with the rebelling against Yagura's rule. As Ryun's group made progress towards the edge of the Land of Water, they were inevitably caught in the conflicts, causing Ryun to have to fight on certain occasions. In one battle, Ryun stole a off a dead shinobi's body, allowing him to fight back. In conflict after conflict, Ryun fought with death knocking at his door, to protect his younger brothers from harm. Nevertheless, there were losses along the way. On two different occasions, one of Ryun's younger brothers were killed, leaving only three surviving Uchiha siblings, including Ryun and Tora. In the aftermath of one of these conflicts, while sitting near the edge of a small river, Ryun met an equally young Seireitou Hyūga, who was also resting, though he doesn't initially know what from. Though initially weary of one another, the two eventually gain the other's trust, and Ryun introduces his two remaining brothers to Seireitou. In subsequent meetings, Ryun shares his ideals and dreams with Seireitou; particularly his desire to create a village where the horrors of the Hidden Mist would never be repeated. One day, their daily meeting by the river is interrupted when fighting breaks out between the Kaguya and the Kirigakure forces. Picking up his tantō to fight, Seireitou is surprised, and mistakes Ryun for a shinobi. During the fighting, a wayward kills Sanji, leaving Ryun and Tora the only survivors of the Uchiha siblings. After the fighting, and resting among the corpses of the deceased shinobi, Ryun and Tora are approached again by Seireitou, this time, bringing an adult man with him. The man introduces himself as Shōyō Kawahiru, a shinobi of Konoha who was traveling with his students to learn more about ninjutsu. Shōyō asks Ryun his name, and Ryun, tearful that a man would care to take him in, replies, for the first time admitting his surname of "Uchiha". Shōyō then accepts both Ryun and Tora among his students.

Team Shōyō
Sometime later, Shōyō leads his group, consisting of Ryun, Tora, Seireitou, and a boy named Hikaru Kurosaki, into the relatively peaceful Land of Mountains. Shōyō had established a small schoolhouse in the foothills of Goddessdrop Mountain in order to teach orphaned children ninjutsu. Here, Ryun learned the basis of ninjutsu and to develop his skills as a shinobi. On one such day, after a long afternoon of training and lessons, Ryun and Seireitou sat on a ledge overlooking the school. There Ryun expands on his idea to create a village, saying that he'll build it around Shōyō's school and that it will be a place of acceptance for shinobi of all clans and backgrounds, even those with kekkei genkai (remembering Yagura's persecution of those shinobi). Seireitou scoffs at him, saying such a dream was ludicrous.

Shortly thereafter, Ryun celebrates his ninth birthday, which is particularly eventful for him, as it is the first birthday he actually celebrates. During the festivities, Shōyō asks him what his dreams for the future are. Much to Seireitou's embarrassment, Ryun tells the group his plans to build a village on the spot where they stand, in order to promote the idea of peace and acceptance throughout the ninja world. To Seireitou's surprise and Ryun's delight, Shōyō smiles and happily accepts the idea; calling it a noble work. After an unknown period of time, Ryun and Seireitou's friendship begins to develop into a rivalry, with both trying to outdo the other. However, the gap between the two boys is greatly widened when Seireitou awakens his clan's kekkei genkai, the Byakugan. Several years later, the broke out and Shōyō desired to take his now-teenage students to the Land of Fire to help extinguish some of the border disputes. There, the group demonstrated their unrivaled teamwork, quelling conflict after conflict for their superior skills. Unfortunately, during the aftermath of one of these conflicts, a group of Amegakure shinobi tracked them to their camp. The following day, these Amegakure shinobi ambushed them, immediately restraining Ryun, Seireitou, and Hikaru, before they could act. They then captured Shōyō, who offers no resistance in exchange for the release of his students, and execute him before their eyes. As his teacher's blood splatters across his face, the pain of losing the only man to ever love him as a father does his son, causes Ryun to snap — the pain from his childhood flooding back in a hatred so intense that Ryun later notes that it felt like an inferno consuming his chest. In these moments, the Sharingan is awakened within Ryun and quickly progresses to the Mangekyō Sharingan, having lost the one person other than his brother, Tora, to have loved him as family.

Advancing His Dreams
After Shōyō's death, the remnants of Team Shōyō retreated to the schoolhouse in the Land of Mountains. There, Ryun declared that the shinobi world must be broken and started anew, but Seireitou, who still carried Shōyō's, suggested that they return to the Land of Fire and continue their duty of quelling border disputes. Ryun grinned, telling Seireitou that he never had understood his dreams, and that, from that point on, they would be rivals of the ultimate sort; battling until his dreams were achieved. From that point on, the two former friends fought on a constant basis, as Ryun tried to build the Land of Mountains' reputation.

The first of these battles occurred along the Shrine River, Ryun and Seireitou fought with the intention of killing each other for the first time. During the fight, Ryun's Mangekyō Sharingan was first put to the test, activating its first technique; Amaterasu. The battle was grueling and long, destroying a great majority of the riverbed and ending in a stalemate — the first of many. According to Ryun, this was the battle that established him as an equal threat to Seireitou. During a subsequent battle, Ryun's experience with the Sharingan began to grow, allowing him to gain the upper hand in the battle for a short time. With each battle, each rival's skills improved, whether Seireitou's Gentle Fist, or Ryun's Sharingan.

As the years went on, Ryun gathered followers in the Land of Mountains, and even among the Uchiha clan in Konohagakure. The two groups would often battle whenever they crossed paths, and the two leaders, Ryun and Seireitou, would always have one of their titanic battles during the course of it. The endless conflict led Ryun to overuse the Mangekyō Sharingan, so, being the now cold and ruthless leader of the Mountains' faction, Ryun had one of his followers killed, and their Sharingan implanted within his eyes, which regenerated his eyesight, allowing him to forever wage war with Seireitou, without fearing the loss of his light. Slowly, Ryun began to see Seireitou as a symbol of the complacent shinobi world; fixated on his views of justice. And for that, Ryun hated him, seeing in him the same thing he saw in Yagura. Yet, his hatred for Seireitou was equaled by his respect for him, and even more by his lust to best him in combat. During another such encounter with his rival, Ryun unveiled his Eternal Mangekyō Sharingan, and his newly awakened ability to preform Susanoo. The battle was of such proportions, that it tore a rift in the valley in which they fought. During this particular battle, Seireitou pleaded with Ryun to let their battles end, so that peace could reign. Ryun retorted that he gained his shinobi skills to make the ninja world pay for the crimes and atrocities it had committed when he was a boy, and that, until it did, he would never be peaceful. In the aftermath of this battle, Ryun returns to Shōyō's old schoolhouse, forming an agreement with the other clans in the Land of Mountains, and officiating the construction of Yamagakure at the foothills of Goddessdrop Mountain. The Third Shinobi World War ended shortly thereafter, and the peacetime allowed Yamagakure enough time to get back on its feet, with Ryun being named the First Yamakage. His dream now closer than ever to completion, Ryun decided to face his old rival one last time and defeat him for good.

Immediately thereafter, Ryun leaves his fledgling village to hunt down Seireitou and end the feud between them once and for all. During this time, he somehow learned that an ancestor of his clan, Madara Uchiha, had survived his battle with the First Hokage, Hashirama Senju. Having never encountered many true members of his clan, Ryun ventured out to find his lost ancestor, until eventually finding him in the. To Ryun's surprise, Madara knew of him, introducing himself as the boy's grandfather, and welcomed Ryun warmly. Ryun did not return this hospitality, however, revealing to Madara the details of his upbringing, the recent war, and his part in it, only for Madara to coldly reply that death and war is the nature of this reality.

In his anger at the response (having remembered his master's death during the war), Ryun activated his Eternal Mangekyō Sharingan, greatly surprising the elder Uchiha, who had himself awakened the exceedingly rare dōjutsu, having, in fact, been the first to do so. After inquiring as to the nature of Ryun's Mangekyō, Madara decides to tell Ryun his, luring Ryun with the possibility of restoring his master to life in the. Ryun declines Madara's invitation to help him along with his plan, but agrees that the shinobi world has become wicked, the events of the previous war still fresh in his mind. Knowing Ryun would be vital to his plan, even if it was against his will, Madara proclaimed that world must end, and that Ryun must be the harbinger of such events. He announces that he will teach the secrets of Uchiha clan's full bloodline to Ryun, as well as the nature of the Yin-Yang Release and the secrets of unlocking the Rinnegan — the ultimate tool of change, as he called it. For several months, Ryun remained in the Graveyard, studying arduously under his grandfather — learning the lore and mythology of the shinobi world, as well as the promised techniques his grandfather had for him.

Becoming a Legend
"Meaningless, huh...?! What do you know of meaningless?! Spend most of your life ruled by . Watch your own siblings dwindle to a handful... and then tell me what has more meaning than your own strength! I have the blood of the Uchiha clan within me, you are but a joke! Yet I've watched you constantly surpass me in strength... my destiny, thrown to the wayside! You have stolen my honor... and your debts... must be paid!"

- Ryun to Seireitou after the latter calls their rivalry "meaningless"

At some point during these months of training, Ryun hears rumors of Seireitou, now an emissary of Konohagakure, making his way to for ceasefire arrangements between the two villages. Seizing the opportunity, Ryun rushed to where Seireitou was. Seireitou, however, has grown tired of their rivalry, calling it "meaningless"; an accusation that greatly enrages Ryun, causing him to claim that Seireitou has no idea what suffering he's been through to get his strength, and that his [Seireitou's] debts must be paid. After hearing this speech, Seireitou agrees to a final battle, declaring that he must end Ryun's once and for all, even if it means killing him. In the opening moves of the fight, Seireitou quickly outclasses Ryun, stating that he must end things quickly. Insulted by this, Ryun activates Sage Mode which greatly surprises Seireitou, who enters his own Sage Mode. The two shinobi's is close to even, causing massive damage to their surroundings, but expending their chakra reserves at a quickened pace. Realizing that Seireitou was once again putting him on the run, Ryun decided to use his true power and play for keeps. His rage and indignation finally complete, Ryun is shrouded in a massive, "final" Susanoo. Due to the form it takes — a large "ten-tailed fox" — Seireitou calls Ryun,.

With his newly completed Susanoo, Ryun begins to dominate the battle, forcing Seireitou to finally take the fight seriously. Seireitou notes aloud that it is ironic how much their rivalry mirrored and 's own rivalry. He then mournfully declares that Ryun's hatred will finally be silenced, much like Madara was. Ryun scoffs at this and decides to unveil his ultimate technique; the Kokuhō. Seireitou seems to recognize the name and begins mercilessly attacking Ryun to prevent the technique's activation. Finally, Ryun is able to form a Kokuhō and fire it. Though Seireitou is able to dodge the bomb itself, the shockwave hits him and critically injures him. His chakra expended and Seireitou wounded, Ryun resolves to finally finish the fight, as his Susanoo disperses. Seireitou makes a final plea to Ryun to end their fight with. Ryun agrees, as his Mangekyō Sharingan reverts to Sharingan, and attacks. As the fight dragged on, Seireitou finally admits that Ryun is a formidable foe, but his hatred makes him dangerous, and therefore he must die. Nevertheless, the two continue to fight on even terms. In a final, desperate move, Seireitou charges his remaining chakra and attempts to plunge his hand through Ryun's heart. Ryun also uses his remaining chakra, forming a small rib cage of Susanoo to protect himself. In a final act of defiance, Ryun delivers a final blow to Seireitou's neck, causing his rival to pass out. The last of his power expended, Ryun's Sharingan deactivates and, leaving his old friend to his fate, limps away from the battle.

Uniting a Land
Sometime after the battle, Ryun returned to the Land of Mountains and his fledgling village to discover that shinobi clans all over the country were at war, and a lot of animosity was being aimed at his new village. Armed with the conviction that he would unite the nation under Yamagakure, Ryun sets out to end the conflicts surrounding his village.

Appearance
While a member of the Yonkō and a veteran of many shinobi wars, Ryun himself is not a very intimidating figure. Aside from his Sharingan eyes, Ryun generally has a look of cold, detachment about him. Ryun has dark eyes and black hair that he keeps in a high ponytail, similar to how the men of the wear their hair. During the, he kept the remainder of his hair in a ponytail, similar to , though Ryun's was far longer. Following the war, however, Ryun cut his hair, allowing it to frame his face only. In his teenage years, Ryun's casual attire consisted of a dark blue kosode and matching hakama. He also wore a black obi tied around his waist. However, during after Shōyō's death, Ryun's attire changed to more clan-centered clothing; a white tunic, and white haori, branded with the Uchiha clan insignia. He also wore a white forehead protector at the time of the Third Shinobi World War.

Not a very imposing figure per say, though Madara did note an air of power around him, Ryun is significantly muscular — likely due to his near constant involvement with combat and combat training, which has increased his muscle mass over the years.

Personality
Ryun is serious, yet arrogant and bitter due to his clan's, as well as the way he was treated and forced to live as a young child on the plains of the Land of Water. His Uchiha lineage, particularly the fact that he is Madara Uchiha's immediate grandson, has bestowed on him and inflated sense of pride and superiority, immediately holding himself and his clan's powers over nearly every shinobi he encounters from the moment he meets them. He is tremendously proud of his Uchiha heritage, considering his clan to be the most powerful shinobi clan in existence, as well as the direct heirs of the 's legacy.

As a surviving straggler of the decimated Uchiha clan, Ryun is originally introduced as an individual hell bent on proving his clan's, as well as his own, great power. Before Team Shōyō was remade into the Yonkō, Ryun was depicted as being cold, arrogant, and even vengeful at times. Nevertheless, it was revealed early on that he had a deep and profound love for his six younger brothers, who also survived the clan's destruction, which has driven him to preform several heroic deeds, while at the same time furthering the hatred for his home village, and strengthening his dōjutsu. He is particular to his youngest brother, Tora, who was the last one left alive after the horrors of the Kirigakure Civil War. Although, despite this, he later is shown to have a genuine affection for Yamagakure, the village he settles down in, and begin forming other bonds outside of Konohagakure. Being born to the ruling lineage of the Uchiha clan, Ryun has, from a young age, been obsessed with achieving the full powers of the clan's bloodline, much like his grandfather. Unlike his close friend and rival, Seireitou Hyūga, Ryun is tactical when it comes to fighting — rushing straight into battle to get a feel for his opponent's abilities before beginning his real attack. However, his hatred, and occasional arrogance, often cause him to underestimate his foes, such as he did in the battle with Myoken. Among the Yonkō, he is easily the most serious, when compared to the eccentric Seireitou and Hikaru, and also one of the most intelligent. During the battle between himself and Seireitou, and Hikaru, he also demonstrated the desire to get to the point, hating the fact that both Seireitou and Hikaru enjoyed toying with each other before getting serious. Despite this, however, he has shown to take some gratitude out of mocking and tormenting his opponents. As a shinobi, Ryun is both cold-blooded and ruthless, so much so, that, in order to draw out Hikaru Kurosaki to fight, he kidnapped and held his son. As a child, however, he was oblivious and jovial, which all changed after the death of his sensei, Shōyō Kawahiru, during the Second Shinobi World War. Following his and Seireitou's battle with Hikaru, he was shown to soften up some, reducing his rivalry with Seireitou to something of camaraderie and sportsmanship. Despite this, he could still kill in cold blood during times of war, when facing an enemy who threatened his bonds with his brothers, as well as the new bonds he had formed with his teammates.

Following this, Ryun became more focused and calculating, focusing on his final, sole determination — to protect his two younger brothers at all costs. This conviction has become so strong that he will quickly sacrifice his own well-being for that of his siblings. He begins to lack empathy for those friends of his who show wavering loyalty to him, or display a threat to either of his brothers, as well as Seireitou, shown when he attempted to kill one such former comrade over threatening Tora, and actually attempting to kill Seireitou. In peace times, or when under great pressure, Ryun has shown a more relaxed side of his personality. In his free time, he enjoys smoking from a. He enjoys taking walks through his village when he is feeling extra stressed, and, while doing so, will often tuck his hands out of the middle opening in his haori, leaving the sleeves to flap wildly in the wind — a trait he shares with.

As the leader of a village, however, Ryun has shown to be stern; making harsh, even cruel decisions at times for the overall sake of the village. These decisions rarely seem to faze him, as he has learned from a young age to kill his feelings when making sacrifices for the betterment of the general population.

Nindō
Ryun seems to have inherited his from his grandfather, Madara Uchiha. According to Ryun, his ninja way is. During his battle with Sannoto Senju, Ryun elaborated, boldly stating that his nindō was shared with not only Madara, but also Hashirama Senju, and even the Sage of the Six Paths himself — though each shinobi had their own interpretation of it. For Ryun, this meant breaking the cycle of war, hatred, and murder, which he had fallen victim to during the as a young boy growing up in the Land of Water, and which he hoped to shield his brothers from. Ironically, however, following his meeting with Madara, Ryun seems to believe that war is the only way to break the world's "cycle". By inflicting the pain he felt on others, he hoped to make them understand one another, thereby stopping their meaningless conflicts. For example, during his battle with Sannoto, he claimed that if Sannoto wouldn't cease the meaningless battle (as Ryun had a clear advantage), he would beat the sense into him so that he would stop.

Rivalry with Seireitou
In light of all of this, his defining trait has always been his intense rivalry with Seireitou and his downright obsession to surpass him in power. Seireitou himself has noted that he and Ryun possess a similar rivalry to Hashirama Senju and Madara Uchiha. From a young age, Ryun has considered Seireitou to be his single greatest obstacle; even going so far as to say that he is the hurdle he must overcome to "break the cycle of the world". In this way, Seireitou exists as the ultimate personification of Ryun's nindō. Because of this, he harbors an unhealthy lust for overcoming Seireitou at every available opportunity. He also seems to have an unnatural enjoyment of fighting Seireitou, having once stated that the only death he foresees as honorable is one that comes in combat with his greatest rival.

Just the feel of Seireitou's is enough to stir Ryun's blood and cause him to prepare for battle. At one point, his desire to surpass Seireitou was so strong that he actually broke down in tears at the thought of not being able to surpass him. Ironically, this obsession had lead him to save Seireitou's life several times, in order to give him the opportunity to beat him himself. His general opinion of Seireitou being seemingly one step ahead of him bordered on contempt until after the two fought Hikaru, turning into genuine respect and friendship from that point on.

Abilities
Ryun is considered to be one of the most powerful Uchiha clan members to have ever been born ; being called the rebirth of his grandfather, the infamous Madara Uchiha. During both Part I and Part II of Enken, Ryun is called a "legendary shinobi", likely due to his role as a war veteran of the Kirigakure Civil War and the, as well as being a prominent member of the Yonkō, and the First Yamakage. During Part II, he is renowned as one of the most powerful shinobi to have ever lived, having himself trained many soon-to-be prominent shinobi as part of his nindō, such as Ryuka Uchiha. In Part I, he was shown to be able to stand up to the likes of Kamui Uchiha, who was said to be stronger than all four Yonkō.

From a young age, as an orphaned child in the countryside of the, Ryun was a skilled individual. For several years, he lead his younger brothers across the countryside, even learning to fight when the Kirigakure Civil War was raging across the land, until eventually being selected by Shōyō Kawahiru to become a student of. He proved himself more than capable of fighting against Kage-level shinobi like Seireitou Hyūga, Hikaru Kurosaki, and Echo Uchiha. He could also easily surpass the former Raikage, and prefect jinchūriki, Kai Saizu. As a Yonkō, his power was such that, during his meeting with Kurisu Taizen, the latter shinobi, also a former Raikage, referred to him as "Ryun-sama" (竜様, Lord Ryun), which was also later an honorific used by Jinsuke Uchiha when identifying him.

Ryun is also notable in Uchiha history, as the one of the few clan members capable of awakening all of the ocular capabilities of the Uchiha clan; the Sharingan and Mangekyō Sharingan, as well as the Rinnegan. Though he accepted it begrudgingly, Yoshitsune Uchiha compared Ryun to Hashirama Senju; stating that it was a compliment due to Hashirama's immense power, and Sannoto Senju claimed that Ryun was the closest person alive to the Sage of the Six Paths. Ryun's power with his various abilities lead him to being able to take on eight S-class ninja, with no harm to himself, and defeat them with little issue.

His tremendous feats may stem from being a transmigrant of, much like his grandfather, Madara.

Chakra Prowess
Ryun's chakra is well known to be both potent, and gargantuan in reserves. The only time Ryun has been known to consciously conserve his chakra is in battles with opponents with chakra levels rivaling his own, such as in his numerous battles with Seireitou Hyūga, Echo Uchiha, and in his brief skirmish with former Hokage, Josho Adashino. According to Kurisu Taizen, Ryun's chakra exceeded his own and was comparable to that of a tailed beast, making him one of the few shinobi to be compared to such — though it is unknown if this is due to his status as a jinchūriki. His chakra is enough to allow him to maintain his Mangekyō Sharingan techniques for long periods of time, and use multiple high level techniques without showing any sign of fatigue.

Taijutsu
Though certainly not his preferred mode of fighting, Ryun has shown a considerable degree of skill in taijutsu. In his battle with Kurisu Taizen, he was shown to have enough versatility to change tactics in midair, surprising his foes before landing his attack. In his earlier battles with Seireitou, he would use taijutsu almost exclusively when he wanted to conserve chakra and feel out his foes strengths and weaknesses. Ryun was at least skilled enough in the art to fend of Seireitou briefly in order to prepare chakra for a counter-attack.

He was also more than capable of fending of Josho Adashino, the Hokage at the time, with taijutsu alone early on in their battle. His speed is the primary feature of his taijutsu skills. He proved fast enough to fight on part with a Sage Mode-enhanced Seireitou, including evading his equally fast golden tendrils, created from chakra he had obtained from Kurama — the Nine-Tails. According to Ryuka Uchiha, one of Ryun's first students, Ryun's speed rivaled that of Otonami Sokudo, one of the fasted recognized shinobi in the village of Konohagakure.

Ninjutsu
Ryun is hailed as one of the most skilled users of ninjutsu in shinobi history, rivaling legends such as Madara Uchiha, Hashirama Senju, and. He has a well-rounded variety of techniques. He is capable of using five basic nature transformations and three advanced nature transformations — one of which is a kekkei genkai nature; eight in total. His mastery of ninjutsu can be attributed, in part, to his mastery of his Sharingan, though most of it is his own skill. Because of this, he has been hailed as the.

Nature Transformation
Due to his Uchiha lineage, Ryun is a specialist with Fire Release ninjutsu. Under Shōyō, he learned to preform the standard Fire Release: Great Fireball Technique. While his fellow students took to learning two or more nature types to increase their arsenals, Ryun devoted his attention to the Fire Release, mastering it to such a degree that the flames can sometimes turn white; a sign of their heat and intensity being brought to the maximum. Due to his massive chakra reserves, he can also create sizable fire techniques, which can reach the same size as his completed Susanoo.

After training under Madara, and awakening the Rinnegan, Ryun trained and mastered several natures, including earth, water, yin, yang, and yin-yang. Sometime during this training, he also had Hashirama's cells implanted into his body, no doubt to assist with the awakening of the Rinnegan; thus giving him access to Hashirama's kekkei genkai, Wood Release. With this particular nature, he steered away from the style of both Madara and, whom both recycled Hashirama's techniques, using, instead, his own devised techniques based on his mastery of yin and yang. With his unique incarnation of the kekkei genkai, Ryun can prey on a target's life energy, causing his technique to use this life energy as fuel and allowing trees to grow. For any human this is used upon, death is instant, as their very life vitality is turned into food for the trees to continue expanding. He can also cause standard trees to grow up from the ground, manipulating their branches for offensive purposes. Using a variant of the Summoning Technique, in combined with his wood nature, he can summon a large, carnivorous plant to release deadly, poisonous spores. He can also create trees which he can then use as a method of transportation.

After learning to significantly control yin, alongside mastery of his Amaterasu technique, Ryun gained the ability to use Blaze Release to manipulate the black flames. His usage is notably more versatile than, say, 's. Using his incarnation, he can further adapt the black flames to his weaponry, allowing him to increase its versatility. He can equip the black flames to his Susanoo, allowing him to equip its weapons with the undying flames, launch flaming magatama, or produce other effects. He can also collaborate with his personal protection squad, combining his black flames with their lightning-type techniques. By further manipulating yin, he can control shadows, allowing for instantaneous movement.

Shinra Banshō
Particularly, he devised an entire fighting style based on the yin-yang nature, after developing his unique technique, Shinra Banshō. Ryun based this technique off of the Ten-Tails' ability to manipulate Yin-Yang chakra in such a fashion, through its jinchūriki. He began to develop this technique shortly after Yamagakure's creation, however, the technique wouldn't form because of the immense amount of chakra required to stabilize and control it. Without the Ten-Tails' gargantuan reserves, this made Ryun shelf the technique for many years. However, after studying the Hachiman kekkei genkai, which allows the user to shape chakra into weapons, that appeared within some clans of the Land of Mountains, Ryun once more began to develop the technique.

Yukimaru Kirigakure noted that the technique is very similar to the sand which protected the in that it responds automatically, completely separate from Ryun's will. Once activated, the technique will seek out any threat, living, or in the form of techniques, and devour it; leaving nothing in its wake. This seems to be only limited to its defensive function, as Ryun can willingly manipulate the shapes of the technique for offensive purposes. These variations include a disk (or disks) of black chakra, which can easily slice through their targets, in a similar manner to wind-natured chakra, a lance which has extraordinary range and piercing properties, and multiple variations of the original, orb-like form, which can then be wrapped around the user to protect them from offensive attacks. He would later go on to invent a more powerful variant of the Shinra Banshō technique to be used as one of his signature techniques. It is considered to be one of the highest forms of Yin-Yang manipulation. To manipulate one of the black orbs, Ryun will "flatten" them, causing them to begin to radiate with intense chakra. Like its parent technique, these orbs can then be manipulated into various shapes to fit the need of the situation. Also like the previous technique, the black chakra is capable of nullifying and devouring all ninjutsu and taijutsu, making the user completely invulnerable to physical attacks. Among the variants Ryun can preform, is the ability to create up to twelve spheres of black chakra, flattening them and then immediately stretching them into several lance-like structures with high piercing capabilities. In this particular variant, the orb gets smaller as the lance is stretched, meaning there is a maximum distance each can travel, dependent on how much chakra is imbued into each sphere.

By overloading yin chakra into the cloak of yin-yang, an aura of intense life-energy is generated, branching out from the cloak itself. The effects are immediate; with the cloak sapping away any nearby life energy, increasing Ryun's own. Ryun will then strike his target with a powerful punch, which will result in an expedited death, as the life-energy is drained more quickly upon contact. The Six Paths Technique can also be imbued into the technique, creating the Six Paths of Rebirth. However, most dangerously, Ryun can combine his unique Yin-Yang Release techniques with his Wood Release, for a devastating combination. With Wood Release: All-Covering Forests and Ten Thousand Things, Ryun first creates an orb of black substance, made from Yin-Yang Release, while at the same time, growing a tremendous tree from the ground beneath it. As both grow in size, the orb seems to attract the branches of the tree inward towards it until they eventually connect, causing all of the tree's branches to follow suit, and fueling the tree's growth — causing it to grow to immense proportions. The results of this are many-fold. Using the orb of black substance as a "source", the tree and its connecting branches and roots become immune to all forms of ninjutsu, with techniques literally dissolving the instant they come into contact with the tree or part of the tree. Ryun can then manipulate the branches in a similar fashion to his Wood Release: Advent of a Wilderness of Living Trees, allowing to deal fatal blows, if not instant death, to anything the tree comes into contact with.

Bukijutsu
Ryun is considered a master in the use of ninja tools. During one of his many battles with Seireitou, he was shown to be able to employ a vast number of strategies involving ninja weapons. He is skilled enough to throw dozens of kunai at the Hyūga, causing enough of a distraction to produce an opening for his own ninjutsu. He has also shown himself to be particularly skilled in the use of shuriken, and can at least wield a sword respectably. In addition, Ryun's shurikenjutsu, in particular, was such that, in his battle with Kamui, he shocked Seireitou at his proficiency — being able to combine it effortlessly with Amaterasu without a single hand seal.

Taking after his grandfather, Ryun makes use of a large red gunbai in combat. It is his preferred weapon when engaging in combat. Like Obito's gunbai, it is highly durable, able to take brutal damage without breaking or being too heavily damaged. He can also use the fan much like one would use a sword, or a war hammer. Due to its durable nature, it can produce heavy damage if used on a human, or other living creature. Using the chain attached to the handle of the gunbai, he can swing it like, turning it into a long-ranged weapon. He can also use the Uchiha Return technique to reflect the damage caused by other ninjutsu back on their users using the fan's flat surface. He could also use it like a sword, parrying blows from other sword users, and even using it to deflect projectiles.

Senjutsu
Ryun learned to utilize senjutsu under the monks at the Temple of the Mountain in Yamagakure. With it, he is capable of entering his unique Sage Mode.

Sharingan
Ryun first awakened his Sharingan when he was seven years of age, during one of his earlier missions with Team Shōyō. Upon witnessing several innocent bystanders be slaughtered by enemy ninja, Ryun's Sharingan awakened, for the first time, with one tomoe. It wouldn't be until three years later, during the, that it would awaken a second time, this time with two tomoe, and from then on, be within his control. At first, Ryun only used the Sharingan for its more novel devices; copying techniques to build his arsenal of techniques, and tracking difficult-to-follow movements. When he was around the age of sixteen he was said to have mastered his Sharingan.

By Part I of Enken, he was able to successfully employ the more useful traits of the Sharingan, such as casting powerful genjutsu with just a glance. By the time he fought Josho, his genjutsu were strong enough to bind and manipulate the Hokage without his even being aware he was under the influence of genjutsu. In his second battle with Seireitou, he was even shown to be able to cast certain genjutsu without even making direct eye contact. Aside from just genjutsu, Seireitou confirmed, in one of their later skirmishes, that Ryun is able to suppress the powers of tailed beasts, even ones such as Kurama, with just his Sharingan — a feat previously only achieved by Madara and.

Rinnegan
Due to being a transmigrant of Indra, who also has Senju genetic material containing the chakra of —thanks to having an artificial left arm made of Hashirama's DNA—Ryun was eventually able to awaken the Rinnegan. Though it is not known how exactly he awakened the Rinnegan, it is known that he had awakened it by the time he had returned from his senjutsu training. With the Rinnegan, he gained access to all five traditional nature transformations, as well as the Yin-Yang Release. Like his grandfather, Madara, he is also shown switching between his Eternal Mangekyō Sharingan and the Rinnegan with ease, in order to use the best of both dōjutsu's techniques and abilities. Perhaps due to his mastery of the technique, he can use Susanoo even while his Rinnegan is activated.

In addition to the standard abilities the Rinnegan grants its users, Ryun also gains unique techniques, born only to his Rinnegan.

Deception & Strategy
From the very beginning, Ryun was an extremely deceptive and intelligent individual, shown by the way he implemented clones as a clever deception during his early battles with Seireitou. He is also extraordinarily talented in deceiving his opponents in order to make them think that he was less intelligent than he actually was. During his battle with Josho Adashino, he made Josho believe that he believed he had cast Tsukuyomi with only his normal Sharingan, causing Josho to underestimate Ryun's intelligence, which led to him being easily trapped in one of Ryun's basic Sharingan genjutsu. He also would frequently lie about his chakra reserves in battle, doing so once in a battle with Seireitou by claiming that he only had chakra enough for one final technique, causing Seireitou to lower his guard and expend all of his own chakra, before pulling out his true final technique, appalling Seireitou and allowing himself to win the battle — the first real victory he had ever had against his rival.

In his battle with Josho, Ryun was shown to purposely hold back his full potential, allowing him to view the true capabilities of his opponents, such as what they were good at, and where their weaknesses lie, before unleashing his true power and targeting their weaknesses. The true extent of his in-battle intuition is shown during his battle with Kurisu Taizen. With only a few moves, he was able to deduce Kurisu's chakra reserves, his nature transformations, the strengths and weaknesses of his implanted Sharingan, as well as how to methodically counter each. Even during the three-way battle between himself, Seireitou, and Hikaru Kurosaki, Ryun proved his intelligence by having Seireitou fight Hikaru whilst he set up elaborate traps and techniques, before truly entering the fray.

Learning Capabilities
Even during his younger days, Ryun was an exceptional learner, being chosen by Shōyō Kawahiru, the most respected Jōnin of his time, for this very trait. Despite his injuries during the Second Shinobi World War, which left him with an artificial limb, created with the cells of Hashirama Senju, Ryun quickly learned to reuse his arm functions, as well as the Wood Release abilities that lie dormant in the arm's DNA. His growth was so extraordinary, that he would frequently even surprise those that were around him constantly, such as in his battle with Kamui Uchiha. He quickly learned form his mistakes, and developed new fighting styles to fill in the gaps left by the previous style. This is best demonstrated throughout the numerous battles he has had with Seireitou Hyūga; with the gap of power between the two tremendously closing with each interval between fights. Perhaps the best known example of Ryun's learning capabilities is his learning to use senjutsu — Sage Techniques. With in the course of a few short months, within the period of the Second Great Shinobi World War, Ryun was able to ascertain the nature of Sage Mode and several sage techniques, enough to put him on par with Seireitou Hyūga, who had mastered the Sage Mode of the foxes long before Ryun himself. In addition to this, he was able to quickly master the training of the White Snake Sage, and learn an immense amount of information during his training with fellow teammate, Hikaru Kurosaki. He was also able to master chakra control within a single day, thanks to his training with Echo Uchiha. Some of his skill progression can be attributed to his mastery of the Sharingan and its useful tools.

Historical Knowledge
Ryun seems to possess a great deal of knowledge on the history and mythology of the ninja world. Following his awakening of the Rinnegan, Ryun seeks out information on the, the dōjutsu's first wielder, first in the of the Uchiha clan, and then at the sacred mural of the Six Paths in the Land of Fire. He also seems to know a great deal about the Ten-Tails, including the beast's true name — Datara.

Perhaps due to his connection with Seireitou Hyūga, Ryun also knows a great deal about the history of the, including who the clan's founder was, and his relation to the First Hokage, Hashirama Senju, as well as the Uchiha clan leader, Madara Uchiha. Being Madara's grandson, he also knows a significant amount of information on the legendary Uchiha, including his prowess during his prime, demonstrated best when he fought Yoshitsune Uchiha. During the battle between himself and the Big Eight, Ryun also showed knowledge on Sannotō Uchiha, a relatively unknown member of the clan, and his famed technique, Amatsu.

Creation and Conception
The idea for Ryun Uchiha came to me when I first joined the Naruto Fanon wiki. He was basically suppose to be me put into the Narutoverse, and still to this day possess traits similar to me; such as his care for his brother. While my care isn't for a blood brother, it is for my cousin, someone I view as a brother and a best friend. His fear of spiders is also inherited from me (I HATE spiders!!). After his revamping, I was going through a lot of bad stuff in real life, and used him as a medium in which to express my horrible and awful emotions and pain.

Upon doing so, my friends frequently commented to me on how much my emotions and my usage of Ryun resembled how Sasuke was developing in the manga. At first I was skeptical. I mean, yes I did read the manga, but I wasn't inspired by Sasuke, nor was I sympathetic to his goals. When I put together the whole Mataiden back story, I chose Danzō as the antagonist, just because he didn't seem to like Uchiha, and he seemed to be willing to even kill children to obtain peace; not because he was responsible for most of the Sasuke-Itachi drama. In fact, I truly hated Sasuke for the way he was acting. In contrast to each other, Ryun actually had a reason for wanting Konoha destroyed. They quite literally sacrificed his brother for peace, while Sasuke had killed his own brother and even knowing Itachi's wishes, went against them.

His nickname, Tsukiakari no Michishirube came about two ways. When I made Tsukiakari, the organization he founds, I had yet to find out their was an anime opening with a song of the same name. The next day, when I was fishing around YouTube for an opening for Part IV, I found it in the form of a Darker than Black opening; an anime I loved, but hadn't caught up on just yet. I gave him that name to be both a pun on the song, and on the organization.

Influences
The largest influence on Ryun was myself. As stated earlier, Ryun is my personal manifestation of the author in the Naruto universe. After he and Seireitou Hyūga's rivalry got more and more intense, both the author and his co-writer, User:Silver-Haired Seireitou, began to notice a similarity between Ryun and Seireitou's rivalry, and that of Goku and Vegeta's own rivalry. From then on, both authors intentionally drew on elements of their respective characters (with Goku resembling Seireitou and Vegeta resembling Ryun), such as enhanced personality aspects, and similar abilities. After the resurrection of Madara Uchiha, and a deeper explanation of his rivalry with Hashirama Senju, both authors realized that their characters represented the canon ideals of the and the, so those elements were also included.

Quotes

 * (To Seireitou) ""Meaningless, huh...?! What do you know of meaningless?! Spend most of your life ruled by another. Watch your own siblings dwindle to a handful... and then tell me what has more meaning than your own strength! I have the blood of the Uchiha clan within me, you are but a joke! Yet I've watched you constantly surpass me in strength... my destiny, thrown to the wayside! You have stolen my honor... and your debts... must be paid!"

Watashi no nindō desu.")


 * (To Suzaku) "Afraid not! There is more than one way to awaken these eyes! Yes... To each his own. My motivation was very different from my grandfather's. My motivation was to be the best! To be the greatest shinobi alive!"


 * (To a ) "Oh, is that a fact? Then why were you surprised when Hyūga activated Sage Mode? I'll tell you why, because your 'recordings' doesn't cover the battles we had during the Second War! Your bonehead creator picked a fine chapter to omit from your records. That's right, my friend — does a clone, like yourself, ever experience fear?!"


 * (To ) "You're not going anywhere! You will pay for your part in this, just like the others. But you should know... I do this not for the village, or my clan, but because you thought you could make the grandson of Uchiha Madara a slave to your whim!"


 * (To Hikaru) "There is no such thing as fair or unfair in battle. There is only victory, or, in your case, defeat!"


 * (To Hikaru and Echo) "It is painfully clear at this point that no one within this team is stronger than Sei is. Not even... myself. So, he deserves to have the fight of a true warrior, and that means... to the death."


 * (To Sannoto) "Yes, it would seem your friends were quite effective before I stomped them. Now's your chance to beat me! A vicious attack now should be sufficient."


 * (To Seireitou) "Sei... The sword in your hand; who taught us how to use it? Our bushido and way of life, who taught us these? The one who gave us a world to live in, was without a doubt, Shōyō-sensei. Yet, this world took him from us. In that case, we have no other choice, but to fight this world. We have to completely            destroy this world that took him from us. Hey Sei, how do you feel living in this world? In this world that took our teacher away from us. How could you live in it, in such a carefree manner? It pisses me off!"


 * (In response to the amount of Mangekyō Sharingan) "Did I miss something?! When was it that the legendary eye powers of the Uchiha clan were reduced to a child's plaything?!"
