Kuron has no past, having started his life as a man. All that he has is his future ahead of him. Kuron is the most impressive and strongest of Trev's creations, though.
Having been created to be a weapon for Otogakure's use, and with such immense power, Kuron flourished once he joined Oto's ranks. He easily helped them take over several small villages, having led a small army for some time as well to help with this, but not needing them until occupation of the needed villages was secured. He led the Sound Five with pride, and was nothing but a weapon for his people. Though, by chance of random fate, he met a man by the name of Junsui Neku and it was this man that would forever change Kuron's life. The man showed him that while he may have been created to be a weapon, it didn't mean he couldn't live some type of life at the same time. Showing Kuron the more Human things in life, Neku opened the man's eyes to the world. Of course, his undying loyalty to Oto never once wavered as he did this. Eventually, it was Neku that became his sworn brother and also helped the man master his Sennika abilities, marking Kuron as the only person to ever master Sennika completely without the help of a seal or restraints. The two were a powerful duo, heading Oto's army and forces to create a deadly and destructive force. Under Kamui's reign, the two were secretly Otogakure's Secret Weapon. And continued to be such until both men disappeared.
Missing in Action
Kuron was a clone made of Hazama's DNA by Trev and because of that, he closely resembled the man, including his green hair. Because of this, once Hazama was revived and found out about it, he felt something needed to be done. Having stolen the body of a Uchiha, which Hazama later unlocked Rinnegan within, he used his powers to subdue and kidnap Kuron. His plan was to torture and then kill the boy but his plans changed once he found out Kuron's strength and power, as well as his accomplishments. Instead of killing Kuron, he would keep the man imprisoned within Mugen, and keep him in case Hazama needed to change Host Bodies. That was over a year ago, maybe two.
Kuron is finally free of Hazama's clutches... But how?
When Kuron travels around his own village, he doesn't wear anything fancy. His clothing consist of a white shirt, black pants(with matching sandals), his arms wrapped in bandages to cover up his purple skin, and a fedora on his head that he got from an unknown source's wardrobe.
Kuron bears light armor over his whole body, resembling samurai armor. The armor over his body is a soft black while he bears a long blue overcoat that allows most of his armor to be hidden.
Underneath his armor, Kuron has a lean yet fit body. His muscles definition is cut and formed. His eyes glow a golden topaz while his hair flows a deep navy green. His skin is untainted by scars or blemishes. As for his face, he is a more handsome man compared to others, his face closely resembling(if not the exact same) as the Godaime Otokage.
