In the final year of the Clone Wars, specifically 19 BBY, a conflict between the Galactic Republic and the Separatist Alliance, Clone Force 99, the Republic's distinguished clone commando squad, brought an end to an insurrection on Yalbec Prime. The clone commandos Tech, Crosshair, and Wrecker, led by their command, Clone Sergeant Hunter, killed the Yalbec queen after Wrecker detached its stinger. Subsequently, numerous Yalbec males also perished as they attempted to mate with the clone troopers, who employed specialized blades to eliminate them. However, while Clone Force 99 was engaged in their operation on Yalbec Prime, they received a communication from Clone Marshal Commander Cody. Cody instructed them to proceed to the planet Anaxes to provide assistance in the Republic's engagements against the Separatist Alliance. Acknowledging Cody's orders, the clone commandos journeyed to Anaxes, where they explained that their arrival had been delayed due to the complications they encountered during the insurrection.
The Yalbec Prime insurrection was initially referenced in "The Bad Batch," the premiere episode of the seventh season of the Star Wars: The Clone Wars animated series, which was broadcast on Disney+ on February 21, 2020. The episode was initially presented as an unfinished story reel at Celebration Anaheim on April 17, 2015, and later made available on StarWars.com on April 29 as a component of The Clone Wars Legacy multimedia initiative.
