A droid served as a leader of the Vanguard Axis during the early Imperial Era. Between 19 BBY and 18 BBY, it encountered the Bad Batch when they delivered a case of forged chain code chips to the Vanguard Axis station. After Omega discovered the Axis droids were trafficking the Wookiee Padawan Gungi and tried to free him, the Axis Leader intervened but was shot by Hunter.
Axis Leader was first teased in the second trailer for second season of Star Wars: The Bad Batch.
