Sector One was a location on the planet Anaxes, utilized by the Separatist Alliance's droid army during the Clone Wars' Battle of Anaxes in 19 BBY. During the battle, a Galactic Republic Low Altitude Assault Transport/infantry gunship traveled near Sector One, carrying Clone Force 99, Clone Commander Cody, Clone Captain Rex, Advanced Recon Commando Jesse, and Kix.
However, the troopers were spotted by a Separatist battle droid scout that alerted an OOM command battle droid and a droid battalion stationed in Sector One about the incoming Republic vessel. Separatist forces subsequently shot down the gunship in a nearby canyon using DSD1 dwarf spider droids. In the canyon, the clone troopers were briefly engaged by the droid battalion, resulting in the ship's destruction. Afterward, the clone troopers pressed forward on their mission to infiltrate a Separatist Cyber Center despite being shot down.
Sector One was introduced in "The Bad Batch," the first episode of the Star Wars: The Clone Wars television series' seventh and final season, which aired on Disney+ on February 21, 2020. The episode originally aired as an unfinished story reel on April 17, 2015, at Celebration Anaheim, and later on StarWars.com on April 29 as part of The Clone Wars Legacy multimedia project.
