The Jem'Hadar second-in-command of a unit stranded on Bopak III in 2372, who distrusts his leader's hope of curing their addiction to ketracel-white and finally leads the men against him.
Arak'Taral appears in the fourth-season Deep Space Nine episode Hippocratic Oath. His commander, Goran'Agar, once survived on this planet without the white and believes something there freed him from it. He has brought his men back and captured Bashir and O'Brien to find the cure.
Arak'Taral obeys, but regards the idea as weakness and the prisoners as enemies who should be killed. He watches them closely and is quick to report O'Brien's attempts to escape.
As the supply of white runs out and no cure appears, the unit's discipline breaks and Arak'Taral turns against his leader. Goran'Agar lets the two officers go and remains behind to deal with his own men, Arak'Taral among them.
