"Why would I spy for an impostor? You have to trust me. I only tried to help Bramblestar before I knew what he was. But now that I know he's not Bramblestar, I want to protect my Clan. I'll do anything you ask."
— Bristlefrost to the cats at the secret meeting in The Silent Thaw, page 238

Bristlefrost is a thick-furred[5] pale gray she-cat[1] with blue eyes.[blog 1]

Bristlefrost is a ThunderClan warrior under Bramblestar's leadership in the lake territories. She is born as Bristlekit to Fernsong and Ivypool, with her sister and brother Thriftear and Flipclaw, and is later apprenticed to Rosepetal as Bristlepaw. As an apprentice, she is shown to be rather smart and is allowed to complete her warrior training earlier than normal, though she fails. She later saves Rootpaw from drowning, leaving him indebted to Bristlepaw. She tries her assessment again and succeeds, becoming Bristlefrost, but quickly becomes depressed as Stemleaf, her crush, rejects her. Crestfallen, Bristlefrost mopes until Rosepetal convinces her otherwise, where Bristlefrost decides to become the best warrior she can be instead.

After Bramblestar's revival, he is adamant on punishing the codebreakers. He easily manages to manipulate Bristlefrost into working with him to catch any cat breaking the the warrior code, which helps him twist it to his own benefits. However, Bristlefrost soon learns her leader is an impostor and agrees to help those wanting to oust the the spirit out of Bramblestar’s body.

A Vision of Shadows

"Ivypool says you came to visit us before. But I don't remember you. We'd only just opened our eyes. You look like Ivypool except you don't have white splotches."
—Bristlekit to Dovewing The Raging Storm, page chapter 3
She and her littermates, Flipkit, and Thriftkit are born to Ivypool and Fernsong. She meets her aunt Dovewing and Dovewing's kits soon after her birth. When she and her littermates get old enough, Ivypool spends less time in the nursery and Fernsong moves in to help care for his kits, which is unusual for a tom.

The Broken Code

"I told you. I'm worried about Bramblestar. He's been acting weird. But you say it's not Bramblestar. And that makes sense. Bramblestar was always kind. He always wanted the best for his Clan, but I think this Bramblestar wants to hurt ThunderClan. He doesn't care who suffers."
—Bristlefrost to the others concerned about Bramblestar The Silent Thaw, page 234
Now apprenticed to Rosepetal, Bristlepaw attempts to complete her warrior training early but fails due to a lack of prey. She also saves Rootpaw when he nearly drowns. After successfully redoing her warrior assessment, Bristlepaw is named Bristlefrost, and confesses to Stemleaf about her feelings for him. Stemleaf politely rejects her instead, which heavily depresses Bristlefrost as she wanted to complete her training early so she could be his mate. She remains this way until Rosepetal convinces her to live her life as she is young. She helps her Clan try and break the ice on the Moonpool, in an attempt to reestablish the Clan’s connection to StarClan.
She becomes obsessed with trying to please Bramblestar, and he lets her do the daily patrols instead of Squirrelflight. Realizing how dedicated Bristlefrost is to the code, the impostor manipulates her into being his eyes and ears in the Clan, resulting in Bristlefrost informing her leader of when Lionblaze and Spotfur crossed the WindClan border, and when Sparkpelt had not caught as much prey as she usually does, resulting in the three getting punished. Bristlefrost later realizes that her leader is an impostor, and begins working against him with several other cats from the Clans to try and restore the true Bramblestar as leader.

Bristlefrost's warrior ceremony
Bramblestar: Then I, Bramblestar, leader of ThunderClan, call upon my warrior ancestors to look down on this apprentice. She...has trained hard to understand the ways of your noble code, and I commend her to you as a warrior in her turn. Bristlepaw, do you promise to uphold the warrior code and defend your Clan, even at the cost of your life?
Bristlepaw: I do.
Bramblestar: Then by the powers of StarClan I give you your warrior name. Bristlepaw, from this moment on you will be known as Bristlefrost. I know that StarClan will honour your skill and determination, and we welcome you as a full warrior of ThunderClan.
Everyone: Bristlefrost! Bristlefrost!

Bristlepaw: "We should send them home already."
Alderheart: "Sunrise needs more time to heal properly."
Bristlepaw: "The others aren't wounded. They should have left days ago."
—Bristlepaw to Alderheart about the Sisters in camp Squirrelflight's Hope, page chapter 10

Bristlefrost: "I really-really-like you. I've always felt that we might be mates one someday. And now that I'm a warrior, maybe this is the time for us to start thinking of each other in a new way?"
Stemleaf: "I'm sorry. I had no idea you felt like this, Bristlefrost. I like you a lot, but I always thought of you as a friend-a really good friend, almost like another littermate. I've never felt...that way about you."
Bristlefrost: "But now that you know how I you think that in time, Stemleaf, you might feel the same way?"
Stemleaf: "I don't think so. Actually I...I like another cat. I'm so sorry, Bristlefrost."
—Bristlefrost admitting her feelings to Stemleaf Lost Stars, page 141

Rootpaw: "But you're one of the greatest cats I've ever met. You saved my life when my own Clanmates were too scared even to try. If it weren't for you, I'd be at the bottom of the lake right now, frozen solid like the medicine cats say the Moonpool is. And you came to check on me every day while I was recovering."
Bristlefrost: "Any cat would have done that. But what have I done since?"
Rootpaw: "No warrior can do much while this leaf-bare lasts. And once it's over, you'll be one of the warriors who gets your Clan back on its paws. I'm sure of it."
—Rootpaw to Bristlefrost Lost Stars, pages 184-185

"Oh, come on. You all heard the leaders. We have to do whatever we can to reach StarClan!"
—Bristlefrost to the other Clans Lost Stars, pages 190-191

Bristlefrost: "We never thanked StarClan for the prey! We must thank StarClan"
Dewnose: "I thanked StarClan. Just not out loud."
Thriftear: "Me too, I said it to myself."
Bristlefrost: "Perhaps we should all say it out loud now, so we know we’ve done it"
Thriftear: "We’re not kits."
Bristlefrost: "It’s important. You heard Bramblestar at the Gathering. We have to stop breaking the code if we want StarClan to talk to us again."
Rosepetal: "Do you really think StarClan would stop talking to us because of something so small?"
Bristlefrost: "It’s not small if every cat does it. I think we should all thank StarClan out loud from now on, after every catch. That way we can be sure we’ve done it, and we can remind any cat who forgets."
Lionblaze: "We can’t start yowling after every catch. We’ll scare off our next prey while thanking StarClan for our last."
Bristlefrost: "Warriors have been giving thanks to StarClan for their prey since the warrior code was invented. It must be important."
Dewnose: "She has a point. There’s a reason it’s part of the code."
Bristlefrost: "Exactly."
Lionblaze: "Okay. We’ll thank StarClan out loud from now on."
Rosepetal: "I’ll mention it to Bramblestar so he can remind the other warriors."

Bristlefrost: "How will StarClan come back if we keep breaking the code?"
Spotfur: "Do you really think they'll come back if no cat talks to me for a quarter moon?"
Bristlefrost: "Not just that. It's lots of things. I never realized how much we break the code without thinking. Every cat has to obey orders."
Stemleaf: "And you're going to make sure that we do?"
Bristlefrost: "I'm just trying to stop you from getting into trouble like Spotfur. You don't want Bramblestar to stop your Clanmates from talking to you too."
Stemleaf: "You don't get it, do you? There's more at stake here than whether we're allowed to talk to each other. Stomething is very wrong. I always thought you were a good cat. Soon we're going to have to make choices. I just hope you'll be ready to make the right ones."
—Bristlefrost arguing with the others The Silent Thaw, page 118

"I'm glad you see it that way. In fact, you seem to understand me more than any cat in the Clan. I appreciate your loyalty. You deserve more responsibility. I wish I could have made you deputy; it's a shame you're far too young. But I trust you, and I hope you realize that I rely on you to keep me informed about the Clan. You're so observant and you take your warrior duties very seriously. Now that Squirrelflight has left, I value you as a confidante more than ever."
—Bramblestar's impostor to Bristlefrost The Silent Thaw, page 317
