Fett's first full appearance in the series occurred in the episode "", in which it is explained that he saved Fennec's life after she was mortally wounded, leaving her in his debt, and that he is looking to retrieve his armor from the Mandalorian. Fett and Fennec follow him in "Slave I" to the planet Tython, where the former explains that his armor belonged to his late father Jango, a Mandalorian foundling, and is, thus, Fett's birthright. In exchange for the armor's return, Fett and Fennec ensure the safety of Grogu, an alien infant the Mandalorian has adopted. When Moff Gideon's Imperial forces attack the group, Fett dons his old armor and helps to fend off the stormtroopers deployed to capture Grogu, but the group ultimately failed to prevent him from being taken by Gideon's Dark Troopers. After revealing to Djarin his status as a true Mandalorian, Fett insists that he and Fennec shall remain indebted to the Mandalorian until the child is safe, and aid his efforts to rescue Grogu in both "" and "", which show Fett as having cleaned and repainted his armor.
