Ryuuki

Ryuuki is a mysterious tailed beast who appeared out of no where. He seems to have an unending hatred for the world. Especially for Otohime and her tailed beast, but no one yet knows why. He has become famous very quickly because of his ability to take on a human form, despite being a tailed beast.

Appearance
Ryuuki is described as a male with a very intimidating physique. Despite how old he is, Ryuuki looks no older than 20 years old. The combination of his height and muscular body, makes him a person who few would dare to oppose. His constant scowl on his face doesn't help with this and just makes even more intimidating. Even some of the bravest of men find themselves shaking uncontrollably in fear.

The tailed beast DNA that was used to resurrect him doesn't seem to have affected his Uchiha traits at all. Like most members of the Uchiha Clan, Ryuuki has hair as black as the night sky. Ryuuki's hair used to reach passed his waist, but he recently cut it so that it barely reaches his shoulders. Much like Tajima, his bangs hang over the right side of his face so that it covers the side side of his face completely.

Background
Hundreds of years ago, Ryuuki was born as a member of the Uchiha Clan. He wouldn't live long because a member of the Senju Clan would kill him before his fifth birthday. Distraught, his parents left the Uchiha Clan to find a way to resurrect their son. Eventually, a mysterious man who would later become the leader of a group of missing-nin approached them. He told them that he had the power to bring their son back to life and he would do it for free.

The man kept his word, but not in the way the imagined. He resurrected Ryuuki by merging the DNA of several tailed beast's with his, allowing him to resurrect him as a tailed beast. A draconic tailed beast. Without remorse, the man took control of Ryuuki's mind and forced him to kill his own parents before sealing his abilities away to return him to his human form. The man raised Ryuuki as his own and soon Ryuuki forgot about his real parents and thought of this man as his true father.

When Ryuuki turned fifteen his adoptive father abandoned him, forcing Ryuuki to fend for himself. He was forced to learn how to control his abilities in order to fend for himself. He mercilessly killed many shinobi during this time, earning him the alias "Chaos Dragon" and "Dragon of the Apocalypse." All these fights allowed him to fully control his powers at a very fast rate and undo the seal without transforming. After undoing the seal, Ryuuki left his own country and went on a quest to find his father.

He never did and he eventually disappear without a trace. Many myths were created about him during his absence. Most of these myths say that his return would mark the end of the world. This of course caused fear to spread among the few who remembered him. Out of fear, a handful of people began to revere him as a god in the hopes that he wouldn't return.

Hundreds of years later, Ryuuki's search lead him to a hideout of missing-nin. This hideout was being destroyed by an angry dragon. Ryuuki saw many similarities between himself and the dragon in terms of power, which lead him to believe his father might be here. Not wanting to be noticed, Ryuuki waited until the dragon disappeared before searching through the remains of the hideout. In little less than an hour, he found his adoptive father dead on the ground. At that moment he swore he would not rest until the entire shinobi world and that dragon were dead at his feet. This anger of his awakened his sharingan that had remained dormant all this time.

Chaos Release
Chaos Release is a very destructive Kekkei Tōta that is unique to Ryuuki. It combines Fire, Water, and Yin Release to allow him to create and control highly destructive blue or red energy.
