X77

X77 is a synthetic human created from the DNA of Naruto Uzumaki, Sasuke Uchiha, and Hashirama Senju. He was created to be the ultimate Shinobi and possesses the Sharingan, Mangekyo Sharingan, Eternal Mangekyo Sharingan, Rinnegan, and Wood Release. He was given nonstandard shinobi training.

Background
After Naruto and Sasuke's final battle, Sakura and Kakashi come to bring them back to the leaf. When they get there they immediately bring them to the hospital, where they start work on synthetic arms for both of them. Sasuke later declines, but they still took the DNA sample from him. They got Naruto's DNA later when they were making his arm. The Root later visited the medical corps and demanded that work begins on a synthetic human at once. They agreed.

They took the three strongest Shinobi to ever live: Naruto Uzumaki, Sasuke Uchiha, and Hashirama Senju. Combining all three of their DNA into fetuses was largely a failure, however over the span of three years they got it right. The seventy-seventh synthetic human was finally a success. The visual prowess of the Uchiha, combined with the Physical prowess of the Senju would make a Shinobi that rivaled the Sage of the Six Paths. Now they needed to make sure he would obey.



X77 started training at the root. He was trained in all ninja arts: Taijutsu, Genjutsu, and Ninjutsu. He awakened his Sharingan through an assassination attempt, which came from rogue ninja. At age 5, X77 became a genin, although he was not assigned to a squad.

X77 continued training, however, he had a new teacher. His new teacher was the retired Hokage, Kakashi Hatake. He would be training him in how to use the Sharingan. He also taught him the Chidori and the Rasengan, which X77 manifested as the Rasenchidori. Kakashi taught him many useful techniques, however, after one year of training with him the root wiped Kakashi's mind and gave X77 the chunin exam, separate from the other Shinobi.



X77, a chunin was now allowed to go on missions. He was assigned mainly A and B rank missions. He would always go solo. Coming back from one such mission, X77 had experienced something never before. He had lost a fight. Reporting this to his manager, his manager brought him to the medical corps where they told him about two Sharingan abilities called the Izanagi and the Izanami. They then proceeded to implant several Sharingan into X77's arm. After every mission, if these new eyes were used they would be replenished.

X77 continued to repeat the same life style, until one day, when he was twelve years old, he was told to compete in the Jonin exams.
