Cinderpelt

Cinderpelt is a dark gray she-cat with blue eyes and an awkwardly twisted leg.

Into the Wild
Cinderkit, Brackenkit, Thornkit, and Brightkit are born to Frostfur, although their names are not mentioned. Frostfur is seen suckling them.

After overthrowing Brokenstar, with ShadowClan elders' help, Firepaw lifts up Cinderkit, though unnamed, and takes her home to her mother with her siblings.

Fire and Ice
Cinderkit and her brother, Brackenkit, are made apprentices. Cinderpaw's mentor is Fireheart, and Brackenpaw's is Graystripe. Cinderpaw is shown as being excited, energetic, and chatty.

Bluestar is ill with greencough and Tigerclaw wants her to come to the Thunderpath. Firestar wants to go in her place but he has to collect herbs, so Cinderpaw volunteers. Firestar tells her not to go but Cinderpaw, to the dismay of Fireheart, doesn't listen to her mentor and comes instead and gets hit by a monster on the Thunderpath, crushing her leg, and her chances of becoming a warrior.

Yellowfang treats her and eventually takes Cinderpaw on as a medicine cat apprentice. Cinderpaw is slowly getting better at walking with her limp.
