The more I think about RotJ, the more I think that this is actually believable, even if Jabba isn’t literally living with his parents. As far as we know, Jabba may not have any actual power in the galaxy. Maybe he’s just been set up for life by his wealthy family, who have given him his own desert hangout and enough spare money to give him the illusion of real power.
Jabba. Ultimate nepo baby 😉
Though there are a number in the Star Wars universe:
Palpatine (terrible grandfather of a nepo baby)
Vader (terrible father of nepo babies)
Padmé (regal nepo baby)
Luke Skywalker (nepo baby)
Princess Leia (nepo baby squared)
Boba Fett (clone nepo baby)
Rey (nepo grand-daughter)
Kylo Ren (angry nepo baby)
Grogu (secret Yoda+Yaddle nepo baby)
Bo Katan (Mando nepo baby)
Threepio (manufactured nepo baby, built by terrible father of nepo babies)
