Jayfeather is a gray tabby tom with blind blue eyes. Jayfeather is a ThunderClan medicine cat that has served under Firestar's, Bramblestar's, the impostor's, Squirrelflight's, Lionblaze's, and Graystripe's leaderships in the lake territories. He was born as Jaykit, and is one of the children of Brambleclaw and Squirrelflight, alongside his siblings Hollykit and Lionkit. He was apprenticed to Brightheart to train as a warrior, becoming Jaypaw. After discovering an extraordinary ability to connect with other cats' feelings and walk in their dreams, he was urged by Spottedleaf to train as a medicine cat. At first, he refused, but he eventually agreed to train under Leafpool. While walking in the dreams of Firestar, Jaypaw heard about the Kin of Your Kin prophecy, realizing he and his littermates were destined to be powerful. He earned his medicine cat name, Jayfeather. When a fire erupted in ThunderClan's camp, it was forced out by Ashfur that Squirrelflight and Brambleclaw were not his true parents. The truth was eventually revealed that Leafpool and Crowfeather were their parents, causing a strain on the family. Shortly after Hollyleaf vanished, he and Lionblaze realized that she was not one of the Three and the prophecy was predicting the Dark Forest's rising. Fulfilling the prophecy, he, Lionblaze, and the third cat, Dovewing, helped the Clans fight off the Dark Forest in the Great Battle. After the battle, Jayfeather, Lionblaze and Dovewing lost their powers, and Jayfeather gained an apprentice, Alderheart, whom he grew very close to. After Bramblestar's revival, he was adamant about punishing the codebreakers. Jayfeather was one of them and was forced to swear an oath of loyalty. He was later exiled by the impostor and joined as a refugee in ShadowClan. He returned to being a medicine cat of ThunderClan after the impostor was taken down.
