Grk'kkrs'arr was a Tusken Raider residing on Tatooine and a member of Sharad Hett's clan. Joining in the hunt for a krayt dragon during A'Sharad Hett's rite of passage, Grk'kkrs'arr was the first to draw blood from the dragon using his gaderffii. Jedi Knight Ki-Adi-Mundi had been fighting the beast, before the Tuskens joined the fight, and after the wound was inflicted by Grk'kkrs'arr, the dragon swallowed the Tusken.
