Lionheart/Main article

Lionheart is a pale golden tabby tom with green eyes, and thick fur around his neck, like a lion's mane.

Lionheart was a deputy of ThunderClan in the forest territories. He was born to Speckletail and Smallear as Lionkit, along with his sister, Goldenkit. He became an apprentice, given the new name Lionpaw, and Swiftbreeze as his mentor.

During his apprenticeship he witnessed Pinestar visiting the Twolegplace, but told nothing to his Clanmates when Pinestar asked him. However, when Pinestar decided to leave ThunderClan and become a kittypet, Lionpaw convinced him to tell the Clan about it himself, and Pinestar said that he would have named him Lionheart. Sunstar gives him this name, Lionheart, when he becomes a warrior. He became mates with Frostfur and had four kits: Brightkit, Cinderkit, Brackenkit, and Thornkit. When Rusty joined ThunderClan, Lionheart was one of his temporary mentors, along with Tigerclaw. After Redtail died, Bluestar makes Lionheart deputy; however, he died, due to his wounds after ShadowClan attacked ThunderClan's camp.
