The main character, Karaoğlan, is a young Uygur Turkic adventurer who worked as a scout in Genghis Khan's army.
His mother was killed in a tribal blood feud and his father (which he will reunite with years later) Baybora had to run while Karaoğlan was just a baby.
Because it originally started as a daily newspaper comic strip, stories were focused for a mature audience with serious issues of war, politics, history and eroticism.
Kebir comic books got successful and began distribution to French-speaking regions of Europe and Canada, as well as north African countries like Algeria, Tunisia, Morocco etc.
This success brought new editions of Kebir comics in English and Arabic (in Iraq under the title "Desert Eagle" at the end of the 1970s).
On June 24, 2010, in a TV interview Yalaz mentioned his new Karaoğlan movie project which is early stages of development.
The new movie was released in 2013, starring Volkan Keskin as Karaoğlan, Hakan Karahan as Baybora, Müge Boz as Bayırgülü, and Hasan Yalnızoğlu as Camoka.
