She then ran off, drawing Grievous after her, allowing Rex and Denal to set charges on the repulsorlift generator for the station. As the droid general was about to finish off Captain Rex, Tano recovered in time to block the attack. He then killed three clones and stunned Rex and Denal. However, General Grievous arrived and engaged them, quickly knocking Tano unconscious. The group was outnumbered yet was able to use EMP grenades to disable the battle droids. He suggested hot-wiring the door, but R3's seeming ineptitude blocked it.

Denal was first to hear them coming and warned his teammates. Tano instructed R3-S6 to disable the shield, but the droid, who was, in fact, a Separatist spy, instead stalled them until battle droids arrived. Denal and the others then reached a door that was ray-shielded. After infiltrating the station with jetpacks, Denal, Rex, Ahsoka Tano, astromech droid R3-S6, and three others clones separated from Skywalker, who ordered them to plant charges to destroy the listening post as he searched for R2. Under the command of Rex, Denal participated in a mission to neutralize a Separatists listening post and to rescue Anakin Skywalker's droid R2-D2. ' I could always hot-wire it, sir.' ―Denal to Captain Rex
