Two spin-offs from The Mandalorian were announced at Disney’s 2020 Investor Day event, while a third was kept a secret until the season 2 finale’s stinger teased a project called The Book of Boba Fett for release in December 2021. After some initial confusion that The Mandalorian would shift its focus to Boba in the third season, Jon Favreau confirmed that The Book of Boba Fett is its own series and will follow the iconic bounty hunter’s adventures in a post-Empire world.
Temuera Morrison and Ming-Na Wen have been confirmed to be reprising their roles from The Mandalorian as Boba Fett and Fennec Shand, respectively, but a bunch of other beloved Star Wars characters could appear in the new series.
The Mandalorian
Right off the bat, the Mandalorian might make an appearance in The Book of Boba Fett. The new show will run concurrently with Mando’s adventures — as will Ahsoka and Rangers of the New Republic — and the two hit it off instantly when they fended off Stormtroopers together.
Just as Boba helped Mando rescue Grogu from Moff Gideon, Mando could give Boba a hand with whatever missions lie ahead in his spin-off.
Bossk
Bounty hunter Bossk only appeared briefly in the original trilogy, but like most of the other bounty hunters, his awesome action figures made him a fan-favorite character anyway.
In the Star Wars canon, Bossk was Boba’s mentor when he was starting out, so there’s a precedent for him to show up in a Boba-centric spin-off.
Cobb Vanth
When Mando went to a shady Tatooine bar in search of fellow Mandalorians in the season 2 premiere “Chapter 9: The Marshal,” a man entered wearing Boba Fett’s armor. Initially, fans thought it might be Fett himself, but he was revealed to be Cobb Vanth.
Fett might not want to team up with the guy who stole his armor and used it to become a notorious gunslinger, but Timothy Olyphant gave a memorable turn as the character, so it would be fun if he appeared in some capacity.
Captain Rex
In addition to playing Boba in the new series, Temuera Morrison could also play some of Jango’s other surviving clones, including an aging, bearded Captain Rex.
An extra in the Battle of Endor who vaguely looks like Rex was retroactively confirmed to be him. The Book of Boba Fett could expand on how this came to be, and what he got up to after the Rebels’ victory over the Empire.
The Sarlacc Pit
The Sarlacc Pit isn’t exactly a character, but it is a sentient being in the Star Wars universe, so it kind of counts. When Boba Fett is last seen in Return of the Jedi, he accidentally flies into the mouth of the Sarlacc and gets gobbled up, seemingly killing him.
Other than the scarring on his face, The Mandalorian made no attempt to explain how Boba survived being eaten by the Sarlacc. Flashback sequences in The Book of Boba Fett can fill in the blanks.
Cara Dune
Since Cara Dune was appointed a marshal for the New Republic in The Mandalorian’s second season, a lot of Star Wars fans are expecting her to play a major role in the upcoming spin-off, Rangers of the New Republic.
It’s already been confirmed that The Mandalorian and its spin-offs will all tie into one another with shared MCU-style story threads, so Cara could be seen alongside Boba and Fennec in The Book of Boba Fett.
Grand Admiral Thrawn
When Ahsoka Tano defeated Magistrate Elsbeth in a lightsaber-on-beskar duel, she forced her to reveal the location of Grand Admiral Thrawn. This teased Thrawn as The Mandalorian TV universe’s big bad.
Since Boba Fett has turned his back on the Empire, he might take on the Imperial Remnants in The Book of Boba Fett, which could include a run-in with Thrawn himself.
Dengar
It won’t really feel like a Boba Fett show if there aren’t appearances by a bunch of other bounty hunters. Boba was introduced alongside some fellow professionals in The Empire Strikes Back and he’ll be forever tied to those characters.
Dengar could be primed for an appearance on The Book of Boba Fett. He’s a Corellian bounty hunter who’s been in the business since the beginnings of the Clone Wars, so there’s a lot of backstory to explore.
Mace Windu
Samuel L. Jackson suggested that Mace Windu could’ve survived the fall from the window on Coruscant in Revenge of the Sith and George Lucas agreed with him, so he’s canonically alive. In an early draft of Revenge of the Sith, a teenage Boba Fett was seen as a bounty hunter just starting out, working with the Separatists. He would’ve been sent to kill Windu to avenge the decapitation of his father.
Lucas ended up cutting all of this from the script, but Boba still deserves his revenge. The Book of Boba Fett could see him journeying to Windu’s hideout to assassinate him and finding him old, grizzled, and badly scarred from the Emperor’s Force lightning.
Han Solo
Han Solo is one of Boba’s many nemeses. He’s the one who bumped Boba’s jetpack and sent him careening into the Sarlacc Pit. Boba is a nemesis of Han’s, too, since he’s the one who froze him in carbonite and hung him on Jabba’s wall. At the time of The Book of Boba Fett, Han is a key figure in the early days of the New Republic.
A standoff between the two gunslingers would be awesome. The character could either be played by a de-aged Harrison Ford (although his lack of interest in the franchise might prevent this) or Alden Ehrenreich, reprising his role from Solo: A Star Wars Story.
