A Jem'Hadar soldier in the episode To the Death who is paired with Jadzia Dax during the joint mission to Vandros IV and tells her about the brief lives of his kind.
Virak'kara is a Jem'Hadar serving under First Omet'iklan in the fourth-season episode To the Death. When Benjamin Sisko's crew and Weyoun's troops reluctantly join forces to stop renegade Jem'Hadar from restoring an Iconian gateway, each Starfleet officer is matched with a Jem'Hadar, and Virak'kara is assigned to Jadzia Dax.
Their conversations on the Defiant provide some of the series' first details of Jem'Hadar life. He tells her that they do not eat, sleep or take pleasure, that there are no Jem'Hadar women, and that the drug they depend on gives them all they need.
Asked his age, he says he is eight. Few live to fifteen, he explains, and one who reaches twenty is named an Honoured Elder; none has ever reached thirty. Dax, who carries three centuries of memory, is left with little to say.
