Kael Diaz - Wayne/Batboy

Kael Diaz/Wayne in this universe is a new member of the original Teen Titans. He is Batman's adopted son, and his brother is Robin, who is in charge of the Teen Titans.
He adopts the personalities of Batman and Red Hood, more lethal than his brother, and attacks from the shadows like his father.
Upon learning of files concerning Jason's death years before he was revived and became Red Hood, he now goes in search of his brother's killer and encounters the Joker's son, thus beginning a rivalry.
But deep down he has a good heart.
