Nightstar

Nightstar is an old black tom with amber eyes.

Into the Wild

 * Nightstar was one of the cats who carried out the ShadowClan coup in Into the Wild to overthrow Brokenstar with the help of ThunderClan. After the coup, Nightpelt seemed to have the most authority within ShadowClan, and Whitestorm treated him as the leader.

Fire and Ice

 * In Fire and Ice, Nightstar goes to the Moonstone to receive his nine lives from StarClan. He names Cinderfur his deputy. When he first appears on the Great Rock, Fireheart is surprised that he became leader. He starts his leadership by arguing with Crookedstar at a gathering about hunting rights to the river. He also argues against bringing WindClan back from exile.

Forest of Secrets

 * He along with the rest of ShadowClan and WindClan, attack ThunderClan when they discover that Brokenstar still lives. Later, when ThunderClan territory was flooded, and they had to go through ShadowClan territory to get to the Gathering, Nightstar accused them of trespassing, and "escorted" them to the Gathering.

Rising Storm

 * When two ShadowClan cats show up in ThunderClan territory the two cats tell ThunderClan that Nightstar was very ill. The two ShadowClan cats were Littlecloud and Whitethroat, who asked Cinderpelt and Fireheart for help. At the end of the book, It is announced at a Gathering that Nightstar had lost all of his nine lives from the illness and Tigerstar had become leader of ShadowClan.

A Dangerous Path

 * In A Dangerous Path, Fireheart learns from Runningnose, ShadowClan's medicine cat, that Nightstar had not been granted nine lives by StarClan because Brokentail, their old leader, was still alive. By the time ShadowClan had learned of Brokentail's death, Nightstar was too weak to make the journey to the Moonstone to receive his lives. Because ShadowClan would have panicked if they'd known the truth, StarClan's rejection of Nightstar was kept secret and the Clan cats were convinced that the sickness had taken all of Nightstar's lives at once.

Midnight

 * In Midnight, Nightstar is the cat who chooses Tawnypelt to represent ShadowClan in the journey to speak with Midnight, showing that StarClan was not angry with him about becoming leader when Brokentail was still alive.

Starlight

 * He also was seen in Starlight, when he expressed nervousness about the ambition of Hawkfrost of RiverClan.

Sunrise

 * When Jayfeather walks in StarClan territory at Moonpool, he sees Littlecloud, who tells Jayfeather that Flamepaw, his apprentice, met Nightstar on his first venture into StarClan.
