Top 5
In season three, Kanan wears a different outfit as well as a mask to cover his blindness. If we get this one, I hope Hasbro can figure out how to give Kanan a removable mask!
In season three, Ezra is older, has a new lightsaber, blaster, outfit and hairstyle. It's probably too much to hope that he would come with a holocron or two, but it would be nice!
AP-5 joind the Rebels in season two after leaving the Empire. It would be nice to have him to go along with Chopper.
Hera's outfit changed the least in season three, but it would be nice to have a figure that looks better than her previous one, especially if the other heroes get updated.
Zeb also has a different outfit in season three, and is also in great need of a better looking figure than his previous one.
