THE DARK TIMES
On Skako Minor, Clone Force 99 helped Anakin Skywalker and Clone Captain Rex get behind enemy lines to rescue the clone called Echo, who was previously thought lost in the escape from the Citadel. But despite the successful mission, Crosshair was vocal about his dislike of regular clones, which he called "regs."
After an Imperial mission to eliminate an insurgency of Separatist droids on Onderon -- only to find organic beings just trying to survive -- the other members of the Bad Batch defected from the new Empire alongside a child called Omega. However, Crosshair remained behind to serve the Emperor and Admiral Tarkin, his inhibitor chip augmented to make him more compliant to following the orders of the new regime.
Crosshair soon became the leader of a new unit of conscripted soldiers as part of the Empire's pilot program to reduce the need for clones. Known as the Elite Squad, the small sampling of highly skilled, enlisted recruits traded their names for numbers and were tasked with neutralizing anti-Imperial insurgents throughout the galaxy. During a mission to Onderon, Crosshair killed one of the soldiers after the trooper questioned his orders to eliminate the civilians they found there.
Later, Crosshair caught up with his old squad on Bracca after scrappers there reported a power surge aboard a Jedi cruiser. The former Bad Batcher trapped his old friends and targeted Omega during a standoff inside the wreckage. Stalking his prey, Crosshair ordered the activation of the engines, nearly incinerating Clone Force 99 in the process. But the Batch escaped with a well-placed explosive while Crosshair and his soldiers were blown back by the energy wave.
