A moustachioed Starfleet admiral, voiced by Fred Tatasciore, who deals with Captain Freeman and the Cerritos on several occasions and demotes Mariner for mocking his pronunciation.
Admiral Vassery is a human flag officer who appears in Star Trek: Lower Decks, voiced by Fred Tatasciore. He is bald, with a heavy grey moustache, and has a habit of pronouncing ordinary words strangely.
He appears in Moist Vessel, in which Captain Freeman has promoted her daughter in the hope of boring her into a transfer. When Mariner cannot resist pointing out the way he says the word sensors, he takes offence and she is promptly returned to the rank of ensign.
He returns in later seasons as one of the admirals who pass orders to the Cerritos, and in Parth Ferengi's Heart Place he joins Freeman in the talks with Grand Nagus Rom over Ferenginar's admission to the Federation.
