Redtail was a deputy of ThunderClan under Bluestar's leadership in the forest territories. He was born as Redkit to Adderfang and Swiftbreeze, along with Spottedkit and Willowkit. Redpaw was given Sparrowpelt as his mentor, and upon completing his training, he received his warriorname, Redtail. After the death of Sunstar, he was made deputy under Bluestar. He and Bluestar shared a close friendship, providing a strong foundation for their Clan. Redtail was noted to be much more quick and clever than the majority of ThunderClan's warriors. However, he was murdered by Tigerclaw, who wished to become ThunderClan deputy himself, and he ascended to StarClan.
