Bok was a combatant of the Morgukai, belonging to the Kajain'sa'Nikto species, and originating from the planet Kintan.
In the year 30 BBY, Count Dooku utilized Bok, along with his father Tsyr, and Kh'aris Fenn, as part of a scheme to instigate a coup on Ryloth. During an engagement with Jedi Knight Aayla Secura, he suffered the loss of an arm and pretended that he had died. Following this, he replaced his missing hand with a cybernetic prosthetic.
Ten years subsequent to this event, Count Dooku extended an offer to Bok, proposing that he serve as the genetic basis for a clone army composed of Morgukai warriors. The Count pledged that the Morgukai would experience a revival on Saleucami and receive training from the Anzati; Bok agreed to this proposition. Regrettably for his objectives, the Republic became aware of the army's existence and dispatched three battalions with the intention of neutralizing the escalating threat that Saleucami now represented.
During the Outer Rim Sieges, Bok recognized an opportunity to exact revenge when he encountered Aayla Secura. His cortosis gauntlet rendered her lightsaber ineffective. However, in the ensuing hand-to-hand confrontation, she swiftly overcame him with ease, despite the disparity in their sizes. Frustrated and humiliated, Bok persistently attempted to defeat the Twi'lek Jedi, only to be repeatedly subdued by her powerful strikes. Aayla commented that he had failed his father's memory. Enraged by the Jedi's insult, Bok launched an attack, but Aayla used the Force-pushed to propel Bok into a laser gate, resulting in his death.
