Stephen Stanton reprises his role as Tarkin, now holding the rank of Grand Moff. He was last heard in the role in Star Wars: The Clone Wars, when Tarkin was an admiral.

This is our first time seeing Tarkin in action on the field as an Imperial. He wears armor similar to General Veers from The Empire Strikes Back.

This episode marks the first on-screen appearance of Alton Kastle. Kastle wears a gray-blue Imperial uniform, and wears an Imperial media badge rather a military rank badge.
