A battle droid commander was a member of the Separatist Droid Army during the Clone Wars. In 21 BBY, the battle droid served under the command of Confederate General Grievous during the Battle of Dorin. When Grievous ordered the commander to escalate the attack, as an act of revenge against the native Kel Dors of Dorin for staying loyal to the Galactic Republic, the Commander sent commando droids to hunt down the survivors of the battle. However, the counter-attack of the Republic fleet, led by Jedi Knight Anakin Skywalker, forced the Separatists to retreat from the planet.
During the Clone Wars, a battle droid commander served in the Droid Army of the Confederacy of Independent Systems. In 21 BBY, the Commander participated in the battle of Dorin, an attack launched by Confederate General Grievous. The battle droid was deployed on the surface of the planet Dorin, where the droid's troops started to overwhelm the resisting forces of the native Kel Dors. The Commander then led the attack on the civilian population of Dorin, causing devastating damage and killing many Kel Dors. The droid was soon contacted by Grievous, who was overseeing the battle from his command ship over the planet, and ordered the droid to press the attack to punish the inhabitans of the planet for staying loyal to the Galactic Republic. In response, the Commander sent several BX-series droid commandos to search and kill any survivors. However, Grievous soon learned that a Republic task force was sent to aid the Kel Dors, and he recalled his troops from the surface. Although the General had his droid starfighters prepared to repel the Republic's attack, the Republic task force was ultimately successful in destroying many of Grievous' ships and routing the rest of the fleet, as well as Grievous himself, out from Dorin.
A field commander during the battle of Dorin, the battle droid followed the orders of General Grievous in a dutiful manner, laying waste to the Dorin civilian population. When Grievous made it clear he wanted all of the Kel Dors death, the Commander agreed, and showed no remorse for sending commando droids to hunt down the people who had survived from the battle.
This battle droid commander only appeared in a script presented at the 2009 Star Wars Fan Days III convention, which served as a prelude to "Landing at Point Rain," the fifth episode of the second season of the Star Wars: The Clone Wars television series. In the script, the droid received a minor, once-speaking role. Since the script does not provide any characteristic information about the Commander, no assumptions can be made of the droid's explicit model or its gender programming.
