This is an odd set with the probot as the chase. I wonder if one of them will be from outside the DS. I'd like to go easy and suggest an alternate dignitary, but I'm going to go big on these:
Vintage Death Squad Commander in the Vader box
Dutch Vander (Gold Leader) in TIE Pilot box
Pretty sure there was a Hasbro wave that included TIE Pilot, Antilles, and Dutch...seems like they've partly copied earlier Hasbro waves for some of these releases. I would love to see what they can do with the old DS Commander - that would instantly be one of my all time favorite Kubes.
