She joins the Prime Minister and Nala Se in their conversation with Tarkin about future cloning, more about the Bad Batch's history, and the Jedi.
When Omega hears from Tarkin that during Order 66, there were reports of the Bad Batch not killing Jedi Padawan Caleb Dume, she heard Tarkin announce he plans to set a test of loyalty for The Bad Batch, making her feel worried. Omega tried to warn the Bad Batch's leader, Hunter of Tarkin's plans for them, but he believes she is just anxious about the recent changes since the formation of the Galactic Empire. Omega then watched the Bad Batch leave before returning inside the Kaminoan facility with Nala Se. After taking a tour of the Bad Batch's sleeping quarters she was thrown in prison along with the Bad Batch after they defect and came to rescue her. She helps to break out of prison and escape from Kamino.
