Onestar/Main article

Onestar is a mottled, light brown tabby tom with amber eyes.

Onestar was a leader of WindClan in the lake territories. Onekit was born to Wrenflight and Stagleap, along with Ashfoot and Morningflower. He became an apprentice named Onepaw, later receiving his warrior name, Onewhisker. He befriended Fireheart after the ThunderClan warrior helped bring them back to their territory after Brokenstar drove them out. He fought alongside LionClan in the Battle against BloodClan.

Onewhisker traveled with the rest of the Clans on The Great Journey, and when they reached the lake, the dying Tallstar made Onewhisker as his deputy, believing he had made a mistake appointing Mudclaw. Mudclaw was furious and led a rebellion against him, however, Mudclaw and his followers lose and Onewhisker received his nine lives and the new name Onestar. He made an effort to prove that WindClan didn't need ThunderClan's help throughout his leadership. After the battle against the Dark Forest, Onestar allowed Breezepelt to remain in WindClan, despite betraying his Clan.

Onestar quickly cut WindClan off from the other Clans when Darktail came to the lake territories, beginning his reign, and eventually revealed he fathered Darktail with a kittypet named Smoke. During the final battle against The Kin, Onestar and Darktail drown each other in the lake.
