A Hirogen alpha hunter who seizes Tuvok and Seven of Nine near an ancient relay station and prepares to take them as trophies.
Idrin is the alpha of a Hirogen hunting vessel. He appears in the fourth-season Voyager episode Hunters.
Voyager is downloading a batch of letters from Starfleet through a network of relay stations that the Hirogen claim as their own. Tuvok and Seven of Nine, sent by shuttle to one of the stations, are stunned and brought aboard Idrin's ship, where the remains of earlier prey hang on display.
Idrin regards the pair as unusual quarry and intends to kill them for their skeletons, the larger one first. Before he can do so, Janeway destabilises the singularity that powers the station. The Hirogen ships are dragged in and the prisoners are beamed away.
