More likely than not, any other appearances would be in a novel, a comic book or maybe even in a flashback episode of The Book Of Boba Fett.
And if that’s true, then it’s possible Matthew Wood will portray the character again soon, though nothing from the actor has signaled that’s the case.
Though the character’s return may have been a lesser celebrated aspect of the episode, Bib Fortuna’s presence served The Mandalorian’s ongoing objective of bridging the gap between the original and sequel trilogies.
Many previously assumed Fortuna died in the destruction of Jabba’s ship in Return of the Jedi so, while his cameo was brief in the series, the door is open for other Star Wars authors to use him in subsequent stories set before that moment.
