Alpha Hirogen

The Alpha Hirogen is the title given to the leader of a Hirogen hunting party or pack. The Alpha is seconded by a Beta. If the Alpha Hirogen is killed or otherwise unable to command the hunting party, the Beta Hirogen replaces him as leader.

The first Alpha Hirogen that the starship USS Voyager found was at the Hirogen relay station. He kidnapped Seven of Nine and Tuvok. 

Another such Alpha came to know that the Hirogen would die out soon unless he found a way to save them. That came in using holodeck programs to have Hirogen warriors fight holograms and not real opponents.
