"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[8] pale gray she-cat[1] with blue eyes.[blog 1]

Bristlefrost is a ThunderClan warrior who has served under Bramblestar's, the impostor's, and Squirrelflight's leaderships in the lake territories. She was born as Bristlekit to Fernsong and Ivypool, with her littermates Thriftkit and Flipkit, and was later apprenticed to Rosepetal as Bristlepaw. She saved Rootpaw from drowning, and he developed a crush on her. She earned her warrior name of Bristlefrost, but quickly became depressed as Stemleaf, her crush, rejected her. After Bramblestar's revival, he easily manipulated Bristlefrost into working with him to catch any cat breaking the the warrior code. However, Bristlefrost soon learned her leader was an impostor and agreed to become a double agent for the rebels. The impostor named her deputy, but when Squirrelflight was named leader following the impostor's defeat, Bristlefrost happily stepped down.

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 saves Rootpaw when he nearly drowns in the lake. 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. After Bramblestar's revival, Bristlefrost becomes obsessed 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 her Clanmates being punished. Bristlefrost later realizes that her leader is an impostor, and begins working against him with the rebels to try and restore the true Bramblestar as leader.
When the rebels wish to murder the impostor, Squirrelflight fears for Bramblestar's spirit and makes Bristlefrost promise to protect him. Following a failed assassination attempt on the impostor's life, he exiles Berrynose and names Bristlefrost his deputy instead, despite her never receiving an apprentice. After a devastating battle between the Clans, Squirrelflight instead chooses Lionblaze as deputy.

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!

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

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. Something 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

"No! We just told you the real Bramblestar is still around! How can you suggest killing his body? What would happen to the real Bramblestar then?"

Rootspring: "I'm sorry for doubting you. But I didn't know what to think. If I didn't like you so much, I wouldn't have felt so angry when it looked like you had turned on me and the others."
Bristlefrost: "You like me? Even after...?"
Rootspring: "I can't help it."
Bristlefrost: "You know why that could never happen, right? This whole terrible situation the Clans are in is because of codebreaking—and that includes cats from different Clans getting together. That's always been against the warrior code."
Rootspring: "Yes, I know. That's why I would never had said anything...Does that mean like me, too?"
Bristlefrost: "Yes...yes, I do have feelings for you. But what can we do about it? Nothing. There's no way it can go anywhere."
—Rootspring and Bristlefrost admitting their feelings for each other Veil of Shadows, pages 250-251

"Oh, don't be sorry, Squirrelflight! I never deserved to be deputy, and I'm sure StarClan would never have approved, no matter what the false Bramblestar said. I'm just not ready. I'm so glad to step back for a cat who's truly worthy."
