Krayt

Krayt was a krayt dragon that lived on the desert planet Tatooine. According to legend, between 19 BBY and around 7 BBY, a tribe of Tusken Raiders settled near Krayt's nest. Krayt began eating one of the Tusken's animals each night and, after devouring every one of the creatures, it moved on to targeting the village's children. The Tuskens' attempts to repel Krayt failed, and in response, they raided a nearby town and captured several villagers to offer as sacrifices to the dragon.

The disappearances of the townspeople attracted the attention of the fugitive Jedi Knight Obi-Wan Kenobi, who freed the remaining captives to take their place. When Krayt arrived, Kenobi revealed his true powerful nature and began an intense hour-long duel with Krayt, which drew the attention of the entire tribe. In the end, the Jedi feigned exhaustion, and when Krayt swept down for a killing blow, Kenobi used the Force to bring the dragon under his control. The Tuskens cheered at the victory, but Kenobi warned them that he would return with Krayt to destroy them if they ever abducted others. The story of Krayt's actions later spread throughout the galaxy as a legend.
