A Pack Leader is the alpha male of a pack of mutant coyotes capable of human speech, that serves the Gaiaphage. This role changes characters several times during the books.
Original Pack LeaderEdit
The original Pack Leader, appearing first in Gone, is a messenger of the Gaiaphage who hunts down Lana. He attempts to force her to teach the coyotes how to kill humans. Pack Leader leads the attack on Hermit Jim's Shack and burns it down, calling the mutated coyotes to the attention of Sam, Astrid, Quinn, and Edlilio. The coyote next brings Drake to the Gaiaphage along with Lana, so she can give him his whip hand. Drake joins the Gaiaphage and the coyotes, led by Pack Leader, assist in the attack on Perdido Beach.
In Hunger, the original Pack Leader is killed by Lana as she attempts to destroy the Gaiaphage, and another pack leader takes over his responsibilities, introducing himself to Dekka later on in the novel.
Second Pack LeaderEdit
During Plague, the second Pack Leader is discovered by Sam, who also discovered the Pack Leader to be infected with the same parasitic bugs that Hunter and Roscoe were infected with. He asks Sam to kill him so that he won't have to die a very painful death being eaten alive from the inside. Sam promises to do what he says under the condition that he show him and Dekka the place where the flying snakes/"Greenies" (responsible by the infection by these bugs) live. Pack Leader fulfills his promise and is then killed by Sam, along with the bugs that were inside him.
Third Pack LeaderEdit
At the beginning of Fear, Drake is seen talking to the third Pack Leader, who complains about his pack being very hungry, and not being allowed to kill humans due to orders from the Gaiaphage. He then adds mischievously that the Gaiaphage didn't say anything about eating already dead humans. Drake and the pack then go looking for people wandering alone and come across Howard. Drake kills Howard by suffocating him, and he is then eaten by the starving coyotes. Later in the book, the pack attacks Sanjit and a group of children that were crossing the desert along with him. Despite Sanjit putting up a fight, the coyotes manage to kill and eat most of the children, with only some managing to escape. In Light, Brianna gets the job to kill all of the coyotes.
