Where Vader is During The Bad Batch in Canon

In The Bad Batch, we follow the mutated Clone Troopers through their voyage into Order 66 and the galaxy's transition from the Republic to the Galactic Empire. The show primarily focuses on Hunter, Tech, Echo, Wrecker, Omega, and Crosshair...but what about Vader during this time period? Where is he in the timeline? What is he doing, in canon, of course? Here is my answer to the best of my ability. Hope you enjoy this one, and may the force be with you!! Learn more about your ad choices. Visit megaphone.fm/adchoices
