Thistleclaw was a ThunderClan warrior who had served under Pinestar's, Sunstar's, and Bluestar's leaderships in the forest territories. He was born as Thistlekit to Poppydawn and Windflight alongside his littermates, Rosekit and Sweetkit, and even as a kit, he was known for being aggressive amongst his peers. He was apprenticed as Thistlepaw to Adderfang, and after becoming a warrior, Thistleclaw became Snowfur's mate, much to Bluefur's disgust. He and Snowfur had one son named Whitekit, and he began training in the Dark Forest, hoping to become deputy and then leader of ThunderClan. Snowfur was later killed by a monster, devastating Thistleclaw, with him blaming it on Bluefur.
He initiated a relationship with Spottedpaw, hoping that she would choose him as a mate when she became a warrior, but she rejected him after discovering him training in the Dark Forest. Thistleclaw mentored Tigerpaw and nurtured the young tom's ambitions and hunger for power. Bluefur knew that Thistleclaw would lead ThunderClan into war and endless bloodshed, so she did everything in her power to prevent him from becoming deputy, including giving up her own kits to be raised in RiverClan. Ultimately, Thistleclaw was killed by a RiverClan patrol, and descended to the Dark Forest, where he attacked and severely wounded Antpelt where Antpelt later died from his injuries. He also trained several cats to prepare for the Great Battle, during which he retreated after Brokenstar's death. Seasons later, he worked with Ashfur but was forced to surrender after the latter was defeated by the Lights in the Mist and fled.
