Tigerclaw

Tigerkit is born to Pinestar and Leopardfoot along with Nightkit and Mistkit. Leopardfoot says that he started out as the weakest of the litter and is now the strongest. Snowfur and Bluefur are worried that Tigerkit is a bad influence on Snowfur's kit, Whitekit.

Later on, Goosefeather tells Bluefur that Tigerkit was meant to die along with his siblings.

Thistleclaw is made Tigerpaw's mentor when he is six moons old. Tigerpaw, Thistleclaw, and Bluefur find akittypet on ThunderClan territory, Tiny. Bluefur notices he's only a kit and is no threat, but Thistleclaw insists that an intruder is an intruder, and then asks Tigerpaw what he thinks. Tigerpaw in return answers, "I think we need to teach the kit a lesson," and Tigerpaw begins attacking the kit. Seeing Tigerpaw would kill the kit if he wasn't stopped, Bluefur made him stop, saying the kit had learned its lesson.

After he becomes a warrior, Tigerclaw quickly establishes himself as a senior warrior, and placed his nest in the middle alongside Thistleclaw's, while new warriors are supposed to settled themselves on the outside of the den. He is also eager for a fight with RiverClan to win Sunningrocks back. He also seemed to carry a dislike for Bluefur, most likely gaining it from Thistleclaw.

Near the end of the book, Bluestar states that she will give him Ravenkit as an apprentice because the young cat needed the encouragement.

In the prologue, Tigerclaw takes place in the battle against a RiverClan patrol, led by Oakheart, for control over Sunningrocks. He is seen pinning Oakheart to the ground and telling the RiverClan cats to leave ThunderClan territory. When Mousefur desperately calls out for help, Tigerclaw saves her and knocks over the RiverClan warrior that had pinned her down. He argues with Redtail, the deputy, when he tells Tigerclaw that they should retreat. Tigerclaw hesitates as he followed Redtail and the patrol back to the forest.

He accompanies Bluestar, Firepaw, Graypaw, and Ravenpaw to the Moonstone. When rats attack, he believes that Barley sent them into a trap to kill Bluestar. He spreads malicious rumors about Ravenpaw, claiming that Ravenpaw was a traitor. This was an attempt to keep the Clan from trusting Ravenpaw so that Ravenpaw would not tell the Clan that Tigerclaw killed Redtail.

After the battle with ShadowClan, Lionheart, who became deputy after Redtail died, dies. Bluestar makes Tigerclaw the deputy. Tigerclaw seems to be happy when Firepaw and Graypaw say that Ravenpaw was killed in the forest, which is not true. However, he tells the Clan that he believed that Ravenpaw could have made a fine warrior.
