During an interview with EntertainmentWeekly, writer and showrunner Jon Favreau was directly asked if Legends characters such as Thrawn (now canon via Rebels) and Mara Jade could appear on The Mandalorian.
Favreau seemingly skirting around answering that flat out but does hint that could be what they’ll end up doing.
FAVREAU: “I don’t want to talk about anything that might be fun for people to discover. We do have conversations. Part of what’s fun to see if we could merge the worlds of the original trilogy, the prequels, the sequels, The Clones Wars, and what’s been considered canon up to this point and what’s been considered part of Legends. I think this show offers an opportunity to bring in all those elements so no matter what your flavor of Star Wars ice cream you like there will be something to enjoy. But you’re asking the right questions.”
Considering this series takes place five years after Star Wars: Return of The Jedi it does allow them to tackle a lot of the Legends stuff that will unlikely be explored in the movies.
Thrawn is already part of Star Wars canon thanks to Dave Filoni putting him in Star Wars Rebels, and certainly could be a figure that potentially is part of assembling The First Order, as the series is confirmed to explore their origins after the fall of the Empire.
Saw Gerrera is a good example of a character from Clone Wars that jumped to the feature films like Rogue One: A Star Wars Story, back to animation with Star Wars Rebels, and now the upcoming video game Star Wars Jedi: Fallen Order.
So, having a live-action version of Thrawn or even others from Rebels showing up in The Mandalorian wouldn’t be terribly unheard of and is more likely given Filion’s involvement.
Mara Jade was an operative of the Empire and future wife Luke Skywalker, all that stuff from the books could be scrapped entirely, but the character certainly could be worked in this series as a force wielding antagonist. Jade starting out as a villain among the founders of The First Order (Snoke and Thrawn?) before possibly taking a more heroic route.
Considering the next wave of live-action movies will explore brand new paths and eras in the Star Wars universe, it wouldn’t such a terrible thing if the Disney+ shows are where the expanded stuff ends up like with their Cassian Andor prequel show and the Obi-Wan Kenobi series.
The second season of The Mandalorian is already gearing-up with Favreau deep into writing the scripts and aiming to direct an episode.
The Mandalorian will begin airing on Disney+ starting on November 12th.
After the stories of Jango and Boba Fett, another warrior emerges in the Star Wars universe. “The Mandalorian” is set after the fall of the Empire and before the emergence of the First Order. We follow the travails of a lone gunfighter in the outer reaches of the galaxy far from the authority of the New Republic.
