The Senators.

Okay, granted, this grouping is more than one character. The presumed timeline for Season 7 is immediately prior/leading up to the events of Revenge of the Sith. By this time Chancellor Palpatine was already sowing the seeds of discontent in the Senate. The war rages on and he shows no signs of willingness to relinquish his emergency powers.

Episode III hinted at the growing opposition in the Senate, but substantive attention to the subject was left on the cutting room floor. The Clone Wars revival is a perfect opportunity to revisit that subplot. Here’s hoping we see Bail Organa, Mon Mothma, Padmé and the other senators make appearances.
