Tomo's parent, specifically the female Ithorian one, resided in Mos Espa in 32 BBY. Captain Neg compelled her offspring into a state of enslavement, repeatedly vowing Tomo's liberation. However, following several months of ceaseless labor extracted from the boy, his parent discerned that Neg's intentions were not genuine in setting him free. Possessing sensitivity to the Force, she identified Qui-Gon Jinn as a Jedi upon observing him, communicating to Jinn her perception of a potent connection to the Force within him. She implored him to save Tomo, and the Jedi Master consented to assist. Succeeding in liberating Tomo from his confinement, his parent expressed her gratitude by presenting Jinn with a repulse booster upon his return with Tomo.
The voice acting for Tomo's parent was provided by Mary Kay Bergman.
