Dexar

(search for full name?)

Captain Dexar was a male Starfleet officer active in the 24th century.

By 2381, Dexar had ascended to the position of commanding officer of the USS Aventine. However, during the Borg Invasion of 2381, the Aventine engaged a Borg cube at Acamar and Dexar and first officer Tovak were killed. Ezri Dax assumed command and successfully led the Aventine through the Battle of Acamar and was eventually assigned as the replacement commanding officer.

She later reflected back on the event, wondering if her position was just due to circumstances, but Sam Bowers insisted that it was because of her ability to lead that she was commanding the Aventine.
