I would give the VHTF crown to the trio of Bastila, Ponda Baba and the Echo Base Rebel Trooper. Thankfully Bastila got reissued down the line and that helped a lot of people.
I think Tarkin would be a good choice for a reissue, too. Well, just because. A Sandtrooper reissue makes sense as well, given what we've seen of the Imperial troops on Jedha.
