A Qomar official rescued by Voyager in 2376 who scorns the ship's primitive technology until he hears the Doctor sing and helps to bring music to his mathematically minded people.
Abarca appears in the sixth-season Voyager episode Virtuoso, played by Ray Xifo. He is among the Qomar taken aboard after their vessel is damaged, and he makes no effort to hide his contempt for Voyager's crew, their medicine and their holographic physician.
His attitude changes when the Doctor hums absent-mindedly in sickbay. The Qomar have no music of their own, and Abarca, fascinated by the mathematics he hears in it, arranges for the Doctor to perform and for Voyager to be welcomed at the otherwise closed Qomar homeworld.
Alongside the scientist Tincoo and the prelate Koru he becomes part of the audience that turns the Doctor into a celebrity, a craze that ends as quickly as it began once the Qomar build a singer of their own.
