Jezrak was a Jem'Hadar and the captain of Sespar's Revenge.
In 2372, Jezrak escorted Odo to a meeting with Auron and Selann. (DS9 novel: The Heart of the Warrior)
- Jezrak's name does not conform with Jem'Hadar names established in "The Jem'Hadar"; this was also the case with M'rak and Thok. Odo noted the ship that Jezrak commanded was of a different design to the Jem'Hadar vessels that Odo had previously seen.
