Pikestar

Pikestar is a tall, thin, muscular dark brown tabby tom.

Dawnflower's Curse
Pikestar is the leader of ThunderClan, and his apprentice is Mothpaw.

When his daughter, Dawnpaw, is out of camp speaking with Beestripe, Jaypaw and Birchfoot hurry over to them and tell them that Pikestar is gravely ill. It is revealed that he has greencough and is going to lose his ninth and final life. Dawnpaw is distraught and runs to camp where she finds him in his den with Poppyheart, the medicine cat, and Sorrelpaw, his other daughter. Dawnpaw presses her nose to his cheek and finds that it is hot. Although Pikestar is unconscious, Dawnpaw whispers to him that he can't die just yet, so soon after Reedpetal, his mate and Dawnpaw's mother, had died from greencough.

Between the end of the book and Acornpelt's Past, Pikestar dies of his illness.

Darkening Shadows
Although not seen, Pikestar is mentioned when Mothpaw tells Dawnflower that Beestripe had offered her the position of his mate if she agreed to kill Pikestar, her then mentor, so Beestripe could become leader, but that she rejected the offer and suggested he ask Dawnpaw instead.
