Saber is the son of El Jefe and foster son of Sly and Carmelita. He has his father's appearance with green eyes.
As a child, Saber was raised by his father after his mother was executed for attempting to betray the tiger. Saber was raised to be a fighter and a killer since he was 3. When Saber was 8, he snuck out of his father's palace with three young bodyguards, Morocco, Grulla, and Jabali. He turned his father to INTERPOL forces, avenging his mother. Saber and his friends were placed into an orphanage where they were adopted by the Cooper Gang.
Unlike his father, Saber is a highly motivated boy but he has a low self-esteem. He just wants to prove to everyone he isn't what his father wants him to be. He fights using katanas that generate fire and lightning on their own, as one of Ray and Gamma's inventions. He is shown to have a romantic interest for Sydney.
Trivia:
Saber's name comes from Saber toothed tiger (despite not being one).
He is the first child of a villain to be introduced from the Sly Cooper universe.
