A nervous young recruit in the Vori unit that takes in Chakotay, whose death in battle is part of the conditioning used to make Chakotay hate the Kradin.
Rafin is a soldier of the Vori. He appears in the fourth-season Voyager episode Nemesis.
After Chakotay's shuttle is shot down, he is found by a Vori patrol fighting the Kradin, an enemy they call the nemesis. Rafin is the newest of the unit, frightened of his first clash, and Chakotay tries to steady him with advice about fear.
Rafin is killed soon afterwards and his comrades fret over the proper treatment of his body. The loss draws Chakotay deeper into their cause. In the end the Doctor shows that the whole sequence was an elaborate indoctrination programme staged by the Vori to turn captured outsiders into fighters.
