Quiet Assassin (Toni)

Toni Ulteria was a member of Amegakure's Ulteria Clan. Orphaned at a young age, Toni and his two brothers, named Z and Sylux, were what some would call prodigies. Toni awakened his Byakugan at age 5 after watching one of his brothers get murdered, in which he also gained Sylux's Sharingan. Later they were found by Kakashi Hatake on a vacation and brought back to Konoha where they were raised.

Background
Toni was a member of the Ulteria Clan, an unknown clan that is made up of direct relatives from both Hamura and Hagoromo Otsutsuki that turned rebel and separated themselves from the rest of the family, because of this Toni and his surviving brother Z were born with a Byakugan, while his brother Sylux was born with a Sharingan due to being directly related to the Otsutsuki. Toni was just 5 when he witnessed a group of ninja murder his brother Sylux, then the ninja take one of his and his brother Z's Byakugan which had only just awakened after seeing the murder of their brother. Beaten and with one eye, the ninja decided to spare the twor emaining brothers, in which where to young to fight back. Later that day they decided to give there brother a proper burial, though during that, Z had noticed that Sylux's eyes were different, they were red... Not knowing what the eye even was, they decided to take them for themselves to remember their fallen brother. With Toni knowing such little medical ninjutsu, he was still able to sucessfully in-plant the two sharingan into him and his brother.

After three years of being wandering orphans, Toni and his brother Z ran into Kakashi Hatake while he was returning from his hokage vacation, feeling sorry for them, he took them back to the Leaf Village. During the evaluation to see if they were fit to be entered into the Ninja Academy, Toni was able to activated his Byakugan and Sharingan at the same time, which shocked all Jonin in the room. Toni then expained how he received his red eye, still not know what it was. As Kakashi explains to him that the Sharingan was a Kekkei Genkai of the Uchiha and that once you have one im-planted you shouldn't be able to deactivate it whenever, he then speculates that Toni and Z must have come from a bloodline that has both sharingan and byakugan in it for them to be able to control both dojutsu. Kakashi allows them to join the Academy with the next generation, which happens to be the class of Boruto Uzumaki.

Personality
Toni is a quiet and gentle person that is often overprotective of his little brother Z, after witnessing the death of Sylux and gaining the Sharingan, Toni made it his made goal t become strong enough to protect his loved ones in his life, because of this he became somewhat of a rebel.

Appearance
Toni is a tall, well built, Ninja with brown sink, black eyes, and black hair. At first glance he looks like a normal ninja, but in-fact he is very deadly in combat.

Abilities
Since being orphaned at a young age after his parents decided to commit suicide, Toni doesn't know any jutsu beside Lightining Style he learned from his dad, and the medical ninjutsu he learned from his mom. Though Toni does wield a sword and because very skilled in his self taught Kenjutsu.

Byakugan
Since Toni knows no moves to take advantage of the sight of the Byakugan, he uses it to improve his swordsmanship, aiming blows for the enemy's tenketsu, he also uses the Byakugan to search for animals he could eat whenever he was starving.

Sharingan
After gaining the Sharingan, Toni learned how to deactivate it one day while trying to activate his Byakugan. He rarely used the Sharingan since he didn't know what it was, but he did know it gave him better hindsight when fighting, so he only ever activated it when he was in danger. Later after learning what a Sharingan is, Toni learned how to do genjutsu and put himself in one where he visualized killing his parents out of revenge for the pain they cause him and his brother, but then it mistakely unlocked the Mangekyo Sharingan for him and Z. After going to Kakashi about it, Kakashi informed them that overuse of the Mangekyo can make the sharingan lose it's light. So from that point forward, Toni and Z agreed to never use it so they don't lose light in the eye they gained from their fallen brother.
