Kamen Uchiha

Kamen is the youngest of the Uchiha brothers but the 3rd strongest. He graduated from the Academy at the age of 11, became a Chunin at the age of 14, mastered his Sharingan at 17, mastered his Mangekyo Sharingan at 23 and became a Jonin at 27. Kamen is sort of mutated. His mother, Riyomi Uchiha died and his father, Matsuda Uchiha married Koino Hyuga and gave birth to Kamen Uchiha. Although he is Uchiha, he has a special kekkei genkai known as Byaringan. The Byaringan is a mixture of Byakugan and Sharingan. So, in this way, he can see the chakra points and dodge any attacks.

He can still use Mangekyo Sharingan without any Hyuga abnormalities.
