Kyo Uchiha

Kyo Uchiha was born in Konohagakure into the Uchiha clan. He was raised as any other Uchiha was, becoming a prodigy like others before him. Kyo's father was the head of the Uchiha, but had an affair with a woman that had only traveled to stay in Konoha for a short time. she became pregnant with Kyo's father's child. Nine months later, Kyo was taken from his mother by his father. He killed her and kept Kyo and raisedh im on his own. He was not of pure Uchiha blood, but advanced faster than other Uchiha did. His father named him after his grandfather, Kyotoumaru Uchiha, the Second Hokage. Kyo's mother was named Rina Yuketsu, a beautiful black-haired women who held the extremely rare Yuketsu Bloodline. This was passed down to Kyo along with the Sharingan. At first, the Yuketsu bloodline did not activate. Kyo became a Genin and had activated his Sharingan, but had not yet awakened his Yuketsu. As a child, he studied under Himura Hyuuga, and partially under Holland Kurushimi. During his yougner years, he was known to be a very intelligent child, but was most notably known for his Sharingan, as most Uchiha were. After becoming a Chuunin, Kyo had already awakened his Third Stage Sharingan. It was at this point that he awakned his Yuketsu, allowing him to learn all types of Nature Transformation. He mastered each element and became best friends with a member of the Senju clan. This friendship was doomed to fail, as Kyo quickly became a Jonin and then Captain of the ANBU Black Ops. His best friend, the Senju, was in his squad with him at all times. Eventually Kyo grew cold, and his goals twisted into a hateful dream. He resented being nothing mroe than a tool of war and being used by the higher-ups of the village. Before defecting from the village, Kyo had one final battle with Holland Kurushimi before killing his family and his best friend from the Senju Clan. It was at that point that Kyo gaiend the ability to use Mokuton, and became a half-blooded Senju. He awakened his Mangekyou Sharingan when he killed his best friend, which led to partial blindness later in life.

Not much is known about what happened to Kyo from his time of defection and his rise to power in Amegakure. It is believed that he killed another Uchiha to gain the Eternal Mangekyou Sharingan. Eventually he took power and formed the Akatuski. He had met Shinji Kurushimi not too long after defectign from the village. Their common hatred of Hollond Kurushimi brought them together. Their mutual anger towards Konoha was what fueled the fire that was the Akatuski.
