10. Nala Se
As a clone of Jango Fett, Boba Fett, like all the other clones that made up the Grand Army of the Republic, was engineered by Kaminoan scientists, the most important of which was Nala Se. The Bad Batch revealed that the Empire destroyed Kamino shortly after the Clone Wars, as the need for clones was no longer necessary.
Nala Se was spared from the fate of her fellow Kaminoans and was taken in by the Empire, though we can only speculate the role she plays in the Empire’s plans from the end of the Clone Wars on. The Book of Boba Fett could possibly feature flashbacks of Boba Fett’s time on Kamino, and that time could include appearances by Nala Se, or the show could even reveal a little of what happened to Nala Se after the Clone Wars.
Was she involved in further cloning experiments for the Empire? Perhaps the cloning of Palpatine himself or the engineering of Snoke? Has she had any interactions with Grogu? How would Boba Fett feel about seeing her again? Perhaps The Book of Boba Fett will shed some light on some of these questions.
