9. Jango Fett
As is common knowledge among Star Wars fans, the bounty hunter Jango Fett was the template the Republic Clone Army was developed from. And at his request, he has given a clone for himself to raise as a son, Boba Fett.
Jango was killed during the Battle of Geonosis by Mace Windu, so he has been dead for several decades to this point, but that doesn’t necessarily mean the character will not appear.
The actor who portrayed Jango, Temuera Morrison, is set to star as Boba Fett in the upcoming show, just as he did during Boba’s appearances in The Mandalorian.
With Morrison set to star in the show as Boba, there remains a possibility he could also reprise the role of Jango in a flashback with Boba as a child.
While this is merely speculation, one of the showrunners for the show is Dave Filoni, who famously produced the Star Wars: The Clone Wars animated series, which featured a young Boba Fett prominently in several episodes.
With his strong connection to this era of Star Wars, Filoni may do a flashback with a young Boba in this era, creating a great opportunity for Jango to have one more scene with his son.
