Manex, a Human male, held the title of Supreme Governor of New Apsolon in the final period of the Galactic Republic; he was also the sibling of Roan.
Manex, possessing substantial wealth, openly displayed his affluence. His preferred hue was green, leading him to adorn his residence lavishly with green elements. Despite initial suspicions of involvement in the death of the previous Supreme Governor, Ewane, he was later exonerated. Manex supported Qui-Gon Jinn and Obi-Wan Kenobi during their assignment on New Apsolon, supplying critical data and providing care for Tahl following her rescue. Subsequent to his brother's passing, he assumed the role of Acting Supreme Governor of New Apsolon. The Jedi brought to justice those responsible for Roan's demise: Ewane's twin daughters, Alani and Eritha, in addition to the Absolute Balog. Following these events, Manex parted ways with the Jedi, intending to participate in the approaching election to retain his designation as Supreme Governor.
