Leia is the only original hero to still be alive in the canon, although Billy Dee Williams’ Lando Calrissian will finally return when Episode IX arrives.
This includes Oscar Isaac’s Poe Dameron, who seems the heir apparent as leader of The Resistance.
Episode IX will be the conclusion of the current Star Wars trilogy, and will also wrap up the narrative fans have been following since 1977’s A New Hope.
In addition to wrapping up Leia’s long tenure in the franchise, the new characters will also get their endings.
