ThunderClan is one of the four clans in the fictional world of Warriors, a series of novels by Erin Hunter. Known for their strength and bravery, ThunderClan cats are typically characterized by their loyalty and fierce protection of their territory, which is primarily located in a forest setting. The clan is led by a leader who is supported by a deputy and a medicine cat. ThunderClan cats are skilled hunters and are adept at climbing trees, which gives them an advantage in their woodland home. They often face challenges from rival clans, such as ShadowClan and RiverClan.
