As the Separatist - aligned king comes under increasing pressure to deal with the growing rebellion , the rebels choose a new leader . " " Plot summary . The Onderon rebels , under the supervision of the Jedi Anakin Skywalker , Obi - Wan Kenobi , Ahsoka Tano , and clone trooper Rex , have begun striking at the Separatist droid forces in Iziz , wrecking them in droves while taking painstaking care not to endanger innocent civilians , and inching their way closer to the Unifar Temple with each step . Seeing this as a direct threat on his life and position , Sanjay Rash , the usurper King of Onderon , has his predecessor Ramsis Dendup brought from the palace dungeons , self - indulgently accusing him of having caused this uprising . Dendup argues that this was triggered by Rash ' s submission to the Separatists , and that only he - as the acting king - has the power to end this , by first ending the droid occupation . Meanwhile , the Jedi and rebels gather in a safehouse to discuss their strategies for the near future . While the rebels and Anakin are confident , Obi - Wan cautions them by noting that the attacks have left the populace fearful of them , and Lux and Steela agree that the rebels must win their people ' s trust first . Following this , Anakin , Obi - Wan , and Rex decide to return to Coruscant and report to the Jedi High Council , while Ahsoka stays behind as an advisor and supervisor so that the rebels will learn to continue the struggle on their own feet , albeit with further material support from the Republic . In order to win the confidence of the Onderon people , Lux suggests attacking the city ' s main power station in order to prevent the droids from recharging and thus deal the occupation army a crippling blow . In order to obtain information for the attack , Saw ambushes a battle droid straggler and takes off its head , from which he downloads the defense formations at the station . After finding the defenses too heavy to risk a direct assault , the rebel leaders devise a plan to harass the droids so much that they call in heavy reinforcements , then use a hijacked tank to blow up the facility . The rebels execute an ambush on a droid patrol inside the city , giving them just enough opportunity to request backup before they destroy the last of them . The first wave consists of two Droideka s , but these are brought down by the combined efforts of Lux , Saw and Steela . The next group includes the much - wanted tank , and while Steela takes out the droid escort with precise sniper fire , Lux and Saw succeed in bringing down the tank ' s droid crew without damaging their prize . But during their attempts to get the tank back into operation , tensions begin to ensue between Lux and Steela against Saw , who is still playing on his ego . Before the group approaches the generator , Steela and Ahsoka separate from Lux and Saw to draw away the droid guards ' attention , and the tank successfully penetrates the generator ' s defense perimeter . Although hampered by a squad of commando droids , they succeed in destroying the generator , causing a major power outage in the city . Under the cover of darkness , the rebels begin to target every droid unit they find within the city , winning the citizens ' adoration and support . During their celebration in their safehouse , Ahsoka becomes once more painfully aware of the attraction that seems to arise between Lux and Steela , but Anakin , who attends the celebration along with Obi - Wan and Rex via holographic projection , both gives her moral support and reminds her to put the purpose before her personal feelings . Then the Jedi address the rebels , warning them of the retribution Count Dooku will surely let follow against them , and in order to present the Onderon people with an idol they can rally to , they propose that the rebels elect a leader from their ranks . Following a brief discussion about their plans for the immediate future , the lower rebel ranks unanimously elect Steela as their leader , much to Saw ' s resentment . But in the meantime , a distraught Rash has to give his report to Dooku , who agrees to send more and better droid reinforcements , but also a more capable general , Kalani , to deal with the uprising . . .
