Lionheart is a ThunderClan warrior and has an apprentice, Graypaw. While on a patrol with Bluestar, they witness Graypaw fight a young ginger kittypet. Impressed with what they've seen, they offer him to join ThunderClan. The next day, he and Whitestorm are surprised to see Rusty accept their offer, and they lead him to their camp. He briefly explains to Rusty about the warrior code and Clan life. When Longtail challenges Rusty's placement in ThunderClan, Lionheart encourages him to prove his worth. After Redtail's death, Bluestar names Lionheart deputy. He and Tigerclaw train the newly renamed Firepaw by showing him the territory and teaching him, Graypaw and Ravenpaw how to stalk prey. He forms a close bond with Graypaw and Firepaw, and gently teases them when they don't pay much attention to his stories during a Gathering. Lionheart remains in camp while Bluestar, Tigerclaw, and the apprentices journey to the Moonstone. However, ShadowClan attacks the camp and Lionheart is killed. Graypaw mourns for his mentor during the vigil, and Bluestar chooses Tigerclaw as his successor. He appears in StarClan during Firestar's leadership ceremony and grants him the gift of courage.
