Here are three cannon facts about Count Duku. Number one, during Duku's time as a Jedi initiate, he began to expect Jedi Master Link Ostana might secretly be a Sith. One day, Duku confronts Ostana, resulting in a heated duel between the two Jedi that Master Yoda had to break up. Following this event, Duku began to spend more time with Master Kostana as he started to look at her as a mentor figure and took a great deal of interest in her work studying the dark side and her theories concerning the Sith. Number two, in 86bby, Duku completed his initiative trials in hope to be selected as the apprentice to Master Kostana due to her missions in hunting down dark side relics. Although Duku fought and defeated Sifo DS in a duel with one hand behind his back and blindfolded during the Padawan tournament, Kostana selected Sifo DS as her apprentice. Duku's disappointment subsided, however, when he learned that Yoda chose to take him on as his apprentice. Number three, in 82bby, Duku was briefly captured by a cult to be used as part of a dark side ritual. It was during his brief captivity that he experienced a series of visions of his future and he used force lightning for the first time in order to kill his captors.
