Role in the series
In his debut Star Wars Rebels: Spark of Rebellion, Lyste also had a few run-ins with the local rebels, the crew of the Ghost in particular. One such incident involved the sabotage of a speeder bike as well as the theft of a few cargo crates. Despite Lyste and his men's efforts to stop the attack, the rebels were successful in their heist.
Some time later in "Fighter Flight", Lyste was in the town of Kothal where he attempted to pressure local farmer Morad Sumar into selling his farmland to the Empire. After Sumar expressed disinterest in the prospect, Lyste took his troops to the farm later that day, where he forcibly evicted Sumar, his wife and their Aqualish farm helper, destroying their home with his troop transport's cannons. The farmer, his wife and the farmhand were later freed while in transit by Ezra Bridger and Garazeb Orrelios who had seen the smoking ruins of the farm from the TIE/ln space superiority starfighter they had recently stolen.
He also met Princess Leia Organa in "A Princess on Lothal", who had arrived with three Hammerhead Corvettes to support the civilian population of Lothal with supplies. Lieutenant Lyste gave the princess the necessary land permit and escorted her to the planet. He knew that Alderaan ships had often fallen into the hands of the rebels in the past. For this reason, the lieutenant had the task of avoiding the abduction of the three Corvettes by insurgents in all circumstances. He not only escorted the three ships from patrolling body groups, but also anchored them with gravitational locks and placed AT-AT combatants aside. At the end of the night, the crew succeeded in kidnapping all three ships and transporting them to the rebel network. That Princess Leia actively supported the insurgents and deceived Lyste from the outset, the officer did not recognize.
