9. Gavin Darklighter
A prominent character in the Star Wars Expanded Universe, Gavin Darklighter could make for an unexpected and interesting lead in this spinoff. His history is long and varied (giving Lucasfilm lots to pick and choose from), he’s one of only a handful of men to have served as a pilot in Rogue Squadron, then Rogue Leader.
He has ties to the original trilogy too, as his older brother is Biggs, Luke’s friend from Tatooine who died during the attack on the first Death Star. That would give Rogue One the opportunity to throw in the kind of mentions and Easter Eggs which make fans happy, but Gavin is far enough removed from the main characters for Edwards to not have to end up worrying about catering to hardcore Star Wars followers.
