What will the protagonist be struggling with in the ST? Anakin Skywalker struggled with separation from his loved ones, death of his loved ones, and wanting to gain more power so he can fulfill his supposed destiny as a galactic savior. Luke Skywalker struggled with finding a connection to his father, living up to what he thought his father was, finding his true family and friends among the stars, trying to become a knight to better help his cause and live up to the expectations of others, and finally cope with the truth and redeem his father. What kind of heroic journey is left for the ST to focus on? The thing that most comes to my mind is the protagonist who rejects using their special gifts for a moral duty (or at all), who wants to separate themselves from their family, who wants to leave behind others' expectations, who wants to escape from it all and live in isolated peace. Like Simba in The Lion King after Mufasa's death, or Peter Parker before Uncle Ben's murder, or even a little bit like Han Solo in ANH. But once they do eventually reintegrate, I think the protagonist shouldn't just assimilate into the old order that they had left behind... the protagonist should transform it into something very new.
