Leafpool

Leafpool was the medicine cat of ThunderClan from the end of New Prophecy and all through Power of Three and Omen of the Stars. She is one of the main protagonists of New Prophecy and is an important character in Power of Three and a supporting character in Omen of the Stars.

Leafpool was born as Leafkit alongside her sister Squirrelkit to Firestar and Sandstorm of ThunderClan. She showed an instant love of healing and was apprenticed to the medicine cat, Cinderpelt, once she reached six moons. When Squirrelpaw goes on the journey to find the Clans' new home, Leafpaw keeps in touch with her through their mental connection, helping her find herbs for her traveling companions.

Leafpaw makes the Great Journey with ThunderClan and finds the Moonpool, the lake territories' equivalent of the Moonstone, with the help of Spottedleaf. She earns her medicine cat name, Leafpool, because of this.

Leafpool falls in love with a WindClan warrior named Crowfeather, who went on the journey to the sun-drown place with Squirrelpaw (now Squirrelflight), and has his kits in secret- Jaykit, Hollykit, and Lionkit. Knowing she cannot keep her kits because she broke the medicine cat and warrior codes, she begs Squirrelflight to pretend the kits are hers. Her sister reluctantly agrees and raises the kits as her own.

After Hollypaw gives up her medicine cat apprenticeship to become a warrior, Leafpool mentors Jaypaw, maintaining a protectiveness over her secret kits that is confusing to them, them not knowing who their parents really are. Leafpool continues to mentor Jaypaw until he receives his medicine cat name, Jayfeather, after his father (though he does not know this). Jayfeather eventually figures out their true parentage after Squirrelflight is forced by Ashfur to reveal that the three siblings are not their kits, and when Hollyleaf uncovers the truth at a Gathering, Leafpool is forced to become a warrior by Firestar.

Leafpool spends time as a warrior in ThunderClan, though she is not good at hunting or fighting at first and sticks close to Squirrelflight. Before the Great Battle, she wishes to help prepare herbs with Jayfeather, and becomes a medicine cat again after the general agreement of the Clan.

After the battle is over, Leafpool assists in mentoring Bramblestar and Squirrelflight's son, Alderpaw, alongside Jayfeather. When ShadowClan's medicine cat, Littlecloud, dies, she travels to ShadowClan to train a kit, Puddlekit, to be a medicine cat, despite there being no proof that he should or wants to be one. She later becomes SkyClan's temporary medicine cat until Frecklewish is found and returned to SkyClan.

While trying to protect the kits of Moonlight, a member of a traveling cat group attempting to live on the border of Clan territory, Leafpool dies in a rockslide. She and Squirrelflight, who both went to StarClan, are given the choice of living or dying, and Leafpool chooses dying, because she is happy in StarClan. Squirrelflight chooses living because she feels that Bramblestar needs her.
