Meikai Uchiha (うちは冥界, Uchiha Meikai) is an S-ranked shinobi hailing from Konohagakure prior to his defection. Meikai is infamous for the powers of his Sharingan, Rinnegan, and his status of being a member of Konohagakure's Uchiha Clan. He serves as the Commander-General of Amegakure's ANBU forces.
Meikai is a tall, fair-skinned and fit man with spiky, black hair that had a slight, blue tint to it. In his younger days, his hair was shoulder-length and he wore the standard Uchiha clan outfit: a high collared black shirt with the clan's crest on its back, which Meikai tended to leave slightly open, and blue pants with bandages around his shins. Around his waist, he had a sash that held a sack, presumably containing his ninja tools. During later years, his hair grew out more and his sash was replaced by a belt, adorned with pouches and various weapons. He also wore another sash strapped across his shoulders which he used to hold his numerous swords.
By adulthood, his hair had grown to waist-length with shoulder-length bangs framing the sides of his face, covering his right eye entirely. Although still relatively young, more prominent creases had developed under each of his eyes. In most cases, his attire took the form of the standard shinobi dress of the feudal shinobi era, consisting of bright red traditional armour — similar to that of samurai — worn over a simple black suit. This armour was constructed from numerous metal plates, formed into multiple protective guards along his body, in particular: chest, waist, shoulders and thighs. Unusually, his chest plate left his back entirely exposed, presumably so as to better display his clan's crest. This clothing was accompanied by boots and gloves, as well as his village's forehead protector which he would later abandon. During battle, he often carried an orange-coloured war fan on his back that had a mitsudomoe pattern, coloured bright red, in both of the top corners.
Just as Hazama's other Zombies, Meikai is dressed as an Otogakure ANBU. Of course, his eyes are within their Eternal Mangekyō Sharingan form. Deciding not to downgrade this man either, he still has access to his weapons, carrying his Gunbai on his back.
As a child, as well as before his fall to the Curse of Hatred, Meikai was a kind, gentle, passionate and highly competitive child who wanted to challenge everything and just about everyone in order to test his strength, and prove everyone he's the best of the best. Meikai has also been noted to be a quite apologetic and sensitive individual. Prior to his corruption of the Curse of Hatred, Meikai believed that words, empathy, and feelings was the only solution to establish peace.
As an adult, Meikai is seen most of the time as a cold hearted, bloodthirsty, power hungry and ambitious man. He will do away with just about anybody who gets in the way of what he desires. Although Meikai is generally shown like this, he does show some amount of sympathy towards people and how miserable this world is and would be better off in an endless loop. While Meikai is shown to be cold hearted and in general cruel, he has, however, been shown to be smiling at least once in awhile. Usually smiling in solitude while mourning for his late wife and lost children, who are discernibly one of the few people Meikai displays affection towards. Different from the usual scowl that is most commonly shown plastered on his face.
Upon his revival as an Edo Tensei zombie, Meikai seems to have become even more sadistic than usual. Although, he is now a bit more knowledgeable and cunning than he was while still being alive. It has also been hinted that Meikai has adopted a laid-back attitude and a love of fighting. He is as of present no longer interested in world domination nor a world filled with genocide. Instead, he is only seeking entertainment and to test the limits of his perfection. While being a minion for the said Otokage, he is still fully conscious of the morality (or lack thereof) of his actions and commits them simply because he wants to, not because he is ordered to. His stated reason for wanting to destroy humanity is simply to see the looks of terror on their faces before they die.
As the Commander-General of Amegakure and former High Council Leader of Iwagakure, just as much as being the founder and previous leader of the Manji ANBU, and former member of the S-rank criminal organisation Akatsuki prior it's dissolution, Meikai is an extraordinarily powerful shinobi and is considered by several notable individuals as a formidable fighter.
Meikai was noted to have been born with an extremely powerful chakra, even by the Uchiha standards, which the ANBU Captain, Shinjiru Uchiha claimed to be far more sinister than the Tailed Beasts' chakra.
As an Uchiha, Meikai is naturally and consistently a master of the Fire Release Nature Transformation. He is able to utilize the clan's coming-of-age technique: Fire Release: Great Fireball Technique with great expertise just as much as being able on utilizing more advanced Fire Release techniques such as Fire Release: Great Fire Annihilation and the Fire Release: Great Dragon Fire Technique. He can also create dragon-shaped fireballs for a wide barrage at an enemy.
During his stay at Iwagakure, Meikai successfully acquired some of Tessuhai Tsuyo's Senju DNA. However, after implanting the mentioned Tsuchikage's DNA into himself, Meikai noted that nothing happened.
As a member of the Uchiha clan, Meikai has displayed skilful use of a wide range of weaponry throughout his entire life from childhood to adulthood. His trademark weapon is the gunbai, which he uses as both a mace and a shield. The one he used is durable enough to block incoming attacks, as well as absorb the force of an enemy attack and then send it back. By flowing chakra through the gunbai, Meikai can produce a large barrier and sharpen the mentioned gunbai.
Meikai awakened his Sharingan at an early age. It is unknown of how he awakened them, but it has been speculated that it has something to do with his father. Meikai was able to master the Sharingan quite early in his life, and as such he also gained access to the Dōjutsu's generic abilities such as seeing chakra, predicting movements, and placing a victim under paralysing hypnotism genjutsu with just a single glance.
- Meikai is Japanese for "Hades" (湯快) and/or "Realm of the Dead."
- Meikai's favorite phrase is "Anger and Hate are Supreme..." (怒りと嫌いは至高, Ikari to kirai wa shikō...)
