In 20 BBY, the three Venator-class star destroyers of his force were attacked by a Separatist fleet commanded by General Grievous. Kenobi ordered all fighters to be launched to counter the ambush, though the fleet was planning on sending a detachment to rescue a group of Jedi Initiates aboard the Crucible. Killer went into battle in his Z-95 starfighter, alongside fellow pilot, Engle, who piloted a Y-wing starfighter. The pilots were able to shoot down some of the vulture droids, but the Republic task force was quickly overwhelmed and Killer was shot down by Grievous's boarding party escort.
