Prelude . After the Battle of Rendili , where the renegade Jedi Quinlan Vos turned himself in , he was taken to Coruscant for judgment before the Jedi Council . Anakin Skywalker , who had participated in the battle , delivered a testimony regarding Vos ' actions during the battle . Having done this , Skywalker was excused . Immediately afterwards , Skywalker journeyed to the Senate Office Building to meet with his secret wife Padmé Amidala . He was instead greeted by one of her handmaiden s who told him that Senator Amidala was tied up with Senate business , while giving him a holodisc from her . As Skywalker traveled to the Coruscant Underlevels to listen to the hologram , he was unaware that he was being tailed by Dark Jedi Asajj Ventress . Ventress revealed herself , catching Skywalker on his speeder in a decrepit building , listening to the hologram . She took it from him with the Force , and listened to it with disgust before destroying it . Ventress told Skywalker that she was on Coruscant hunting down Quinlan Vos and Obi - Wan Kenobi , before she decided to settle for him . She then proceeded to threaten Senator Amidala ' s life ; Skywalker , who thus became enraged , viciously attacked . The duel . Easily fending off Skywalker ' s strikes , Ventress commented on how pitiful his attack was . Overleaping a slash at her legs , she asked herself why she was wasting time with Skywalker when she could be looking for Senator Amidala . With that , Ventress retreated further into the building , with an enraged Anakin Skywalker in hot pursuit . Ambushing the Jedi , Ventress managed to slash Skywalker across the face , leaving him with a scar on his jaw . As they leapt apart , Ventress quickly pressed the attack . As they fought , Ventress managed to again slash Skywalker across the face , leaving him with his distinctive vertical scar next to his eye . Skywalker returned the favor , slashing her across the left cheek . Scarcely noticing the injury , Ventress taunted that she could have decapitated Skywalker with that stroke , and stated that in their last contest , Skywalker got lucky . She went so far as to say that she would teach Skywalker a last lesson regarding the superiority of the Dark Side before she killed him . Unfortunately for her , she pushed Skywalker too far , causing him to snap completely . Unleashing a flurry of destructive blows , Skywalker drove Ventress to the edge of the building , before blasting her off the edge and telekinetically entangling her in a number of live electrical wires . He then tortured her by holding her in the wires with the Force as she was electrocuted , before he finally dropped her . The wires snapped , unable to take Ventress ' weight , and she became further entangled as she fell into a pit below . Skywalker stared at the pit for a few seconds , before turning his back on his defeated enemy , and leaving . Aftermath . By submitting to his rage during that fight , Anakin Skywalker had pushed himself closer to the dark side of the Force and his own eventual fall . Despite her extreme injuries , Asajj Ventress survived .
