Warning: Contains SPOILERS for The Book of Boba Fett, episode 2
The Book of Boba Fett sees Temuera's Morrison's former bounty hunter set on holding his position as Daimyo of Tatooine, and the reason behind it is much greater than simple power lust. Episode 2 developed on the flashbacks focusing on the main character's past with the Tusken Raiders, following Boba's near-death experience in the Sarlacc pit. The flashbacks saw Boba accepted into the Tusken tribe as one of their own. This shows just how important the Tuskens are to Boba, and this is bound to have an effect on his current motivation in replacing Jabba the Hutt.
The Book of Boba Fett episode 2 saw Boba stop a Pyke train gang in order to make the Dune Sea more hospitable for the Tuskens. In the process, he taught the Tuskens how to ride speeder bikes, and the Tuskens taught him how to fight with a gaffi stick. After the train heist, the Chieftain offers Boba a lizard that guides him through the night. When he returns to the tribe, Boba is holding a branch he thought he only dreamt of, and the Tuskens teach him how to turn it into his own Tusken gaffi stick. Boba Fett has renounced his bounty hunter past and embraced his identity as a Tusken Raider.
When Boba Fett gets his bounty hunter suit back from Din Djarin in The Mandalorian, he describes himself as "a simple man making his way through the galaxy." He adds that he gives his allegiance to no one (to Din's apparent surprise), which means that although he is taking back his suit, he is not returning to his pre-Sarlacc past. He has bigger plans: as it turns out in The Book of Boba Fett, he wants to fill in the power void left by Jabba's death in Tatooine's criminal underworld. But all flashback details hint that Boba doesn't want Tatooine for himself, but for the Tuskens.
Boba Fett's Flashbacks Mean The Tusken Raiders Must Return In The Present
It's thanks to the Tusken Raiders that Boba survives after escaping the Great Pit of Carkoon in a very weakened state - even though the Tusken Raiders take him as a slave, drag him across the desert tied to a Bantha, and then have their children beat him with sticks. As a (former) bounty hunter, Boba Fett has an impeccable code of honor and he knows he owes his life to the Tuskens. He gradually earns their trust and enters their family (especially after he saves the Chieftain's child and returns to the Tusken tribe instead of running away in episode 1).
The events of Book of Boba Fett's episode 2 show Boba become a Tusken himself through the symbolic act of being dressed in the tribe's black robes (that explain his changed appearance in The Mandalorian season 2). The Tuskens are Boba's life after the Star Wars: Return of the Jedi timeline. Although the present timeline hasn't featured the Tusken Raiders yet, they are bound to reappear in Boba's life as he tries to eliminate the Hutt threat and secure his throne on Tatooine.
Boba Fett Is A Different Kind Of Tatooine Ruler To Jabba The Hutt
Boba Fett kills Bib Fortuna and takes over Jabba's old throne in his Mos Espa palace. However, he doesn't consider himself a replacement of the Hutt crime lord, as he tells Fennec (Ming-Na Wen), "Jabba ruled with fear. I intend to rule with respect." He refuses to torture the Gamorreans, instead employing them as his guards, and uses an empty Rancor cage to scare the Order of the Night Wind assassin into talking. Boba chooses violence as the last resort in a world that's used to violence as the norm. If he wants to bring down the criminal enterprise Jabba and the Hutt Clan built, Boba will have to climb its ranks and dissolve it from the inside.
Theory: Boba Fett Wants To Change Tatooine For The Tusken Raiders
After Boba stops the Pyke train, the Chieftain tells him about his people's history: the Tuskens have survived the drying of the Tatooine oceans by hiding and killing. Boba starts seeing the Tuskens as oppressed people, terrorized by the moisture colonists, settlers, and gangsters. These are the same people that saved his life after the Sarlacc escape, and he wants to help free them from under the thumb of Tatooine's criminal underworld. The Book of Boba Fett's train heist was the first step in claiming back the land for the Tuskens.
From here on out, Boba will have to take back the Tuskens' land one step at a time - this means climbing the ranks of the criminal enterprise Jabba left behind. He knows claiming the Dune Sea is not going to be an easy task, but his bounty hunter honor code dictates he must, after the Tuskens saved him, nursed him back to health, and welcomed him into their family. By gaining control of Tatooine's desert, Boba can bring peace and stability to a land that's known nothing but war and oppression for years. Boba wants to make the Dune Sea more hospitable for everyone, including his new Tusken family.
Will Boba Fett Succeed In His Tatooine Change?
The Book of Boba Fett episode 2 made it clear there are several enemies making a claim to the Tatooine throne, including the Ithorian mayor Mok Shaiz and the Twins, who prove that the Hutt Clan survived Jabba the Hutt's death. Boba Fett can't just kill the Hutts, as this would unleash a revenge movement Boba and Fennec couldn't handle. The Hutt brother urges Boba to "sleep lightly" as the Twins temporarily depart, but Boba spends his nights in a Bacta tank, in deep sleep and remembering his time with the Tusken Raiders. It remains to be seen how Boba and Fennec will handle the Hutt threat, as the Twins promise to be major antagonists in the series and the Hutt Clan is one of the Five Syndicates controlling the criminal underworld in the galaxy. If Boba is to succeed in his Tatooine change, he will have to make use of all the help he can get. However, considering where The Book of Boba Fett flashbacks are going, the Tusken Raiders might just prove enough for the task.
