"From now on, let us face new threats as StarClan intended—five Clans united."
— Alderheart after all five Clans make peace in The Raging Storm, page 322

Alderheart is a sturdy[18] dark ginger tom[1] with a white-tipped tail,[19] and amber eyes.[1]

Alderheart is a ThunderClan medicine cat who has served under Bramblestar's, briefly Tigerstar's, the impostor's, Squirrelflight's, Lionblaze's, and Graystripe's leaderships in the lake territories. He was born as Alderkit to Squirrelflight and Bramblestar, alongside his littermates, Sparkkit, Juniperkit, and Dandelionkit. He was originally apprenticed to Molewhisker; however, he later became a medicine cat apprentice with Jayfeather as his mentor. StarClan sent him on a quest to find SkyClan, but he and his companions were unsuccessful, instead meeting Darktail and his rogues. On the journey back, Alderpaw and Needlepaw found two abandoned kits, Twigkit and Violetkit, and took them to join the Clans.

Alderpaw helped raise Twigkit, even taking her to visit Violetkit, who was claimed by ShadowClan. After completing his training, Alderheart served his Clan with compassion and empathy, and he was overjoyed to see that Needletail made it to StarClan. He strongly believed that SkyClan should have a place beside the other Clans at the lake and later became ThunderClan's sole medicine cat after Jayfeather was exiled by the impostor. After being forced to train Flipclaw as his apprentice, Alderheart was exiled by the imposter for standing up to him, and he stayed in ShadowClan briefly as a refugee. He provided assistance to the rebel group in confronting the impostor, and was welcomed back to ThunderClan after the impostor's exposure, and subsequent capture, during a battle with the rebels and members of all five Clans. After the death of Willowshine, Alderheart went to RiverClan to act as their temporary medicine cat.

A Vision of Shadows

"We need you in ThunderClan, Alderheart. You're a good medicine cat. You work hard to keep your Clan healthy, and you have a real connection to StarClan. And you're young: you’ll take care of the next generation of ThunderClan cats, just as you looked after Twigpaw. If ThunderClan had to lose you, it would be like a wound that wouldn't heal."
―Jayfeather to Alderheart River of Fire, pages 238-239
Alderkit and Sparkkit are the only surviving kits of Squirrelflight and Bramblestar's litter. Under the pressure of being the son of the leader and deputy, Alderkit is nervous and anxious, but determined. He is given the name Alderpaw and is apprenticed to Molewhisker, but unlike his sister, who shows a natural talent for hunting, Alderpaw struggles through his training. Bramblestar encourages his son to become a medicine cat apprentice after Leafpool and Jayfeather receive a vision, and at the Moonpool, Alderpaw is chosen by Firestar to go on a quest to find SkyClan. He, Sparkpaw, Molewhisker, Cherryfall, Sandstorm, and Needlepaw of ShadowClan go on the journey. At the gorge where SkyClan lived, the group finds Darktail and his rogues instead, who claim to be SkyClan. After learning the truth, they return home unsuccessful.
On the way back, he and Needlepaw find two abandoned kits. They name them Twigkit and Violetkit, and after some disagreement, the kits are taken to ThunderClan. At a Gathering, ShadowClan and ThunderClan fight over the kits, with ShadowClan claiming Violetkit. Alderpaw acts as a fatherly figure toward Twigkit and communicates with Needlepaw so the sisters may meet in secret. When yellowcough weakens ShadowClan, WindClan refuses to share lungwort that was only found on their territory, and Alderpaw speaks against their immorality. Jayfeather is impressed by his apprentice and names him a full medicine cat as Alderheart.
When Darktail and his Kin take over ShadowClan, Alderheart worries for Needletail and Violetpaw, mourning when he hears of Needletail's death. Though Twigpaw brings SkyClan back to the lake, Alderheart's relief doesn't last long, and he grows frustrated with Sparkpelt when she and several other cats oppose SkyClan settling at the lake. Alderheart desperately misses Twigpaw when she chooses to live with her family in SkyClan, but welcomes her when she returns. He falls for a kittypet named Velvet when she seeks shelter in ThunderClan from a fire. However, he assures Jayfeather that he is loyal to ThunderClan despite his feelings for Velvet and says good-bye to the kittypet at the Twolegplace.
Alderheart saves Puddleshine's life when he is caught in barbed wire by using deathberry skins. When Tigerstar discovers Alderheart's unusual methods, Tigerstar makes Alderheart become ShadowClan's temporary medicine cat as Puddleshine recovers. In ShadowClan, Alderheart becomes close to Shadowkit, one of Tigerstar's kits, and notes the kit's future as a medicine cat. Alderheart continues to advocate for SkyClan's place at the lake and is relieved when all five Clans make peace at last.

The Broken Code

Alderheart: "In all the times I have shared dreams with StarClan, our warrior ancestors have never asked any cat to serve a leader without question. Sometimes it's right to question! How much more devastation would Darktail have caused if none of his followers had questioned him?"
Bramblestar's impostor: "The code says you will obey your leader! But since you've made it clear you can't do that, you can leave too! ThunderClan has no use for a faithless medicine cat!"
Alderheart: "What about a faithless leader?"
Bramblestar's impostor: "Get out!"
—Alderheart standing up to the impostor Veil of Shadows, page 188
Like the other medicine cats, Alderheart is worried when StarClan cannot be contacted when the Moonpool freezes over. Bramblestar falls mysteriously ill, and Shadowpaw informs them of a cure for him. Both medicine cats try it, but it initially doesn't work, and Bramblestar dies. Alderheart grieves for his father, but when he revives, he is overjoyed. Rootpaw summons Bramblestar's ghost for the medicine cats and reveals the truth about the impostor. The false Bramblestar exiles Jayfeather for being a codebreaker, leaving Alderheart as the sole medicine cat of ThunderClan. The impostor also often yells and berates the dark ginger tom, later forcing Alderheart to reluctantly train Flipclaw as a medicine cat apprentice, much to both cats' dismays. Alderheart is exiled after he stands up to the impostor, leaving Flipclaw as the sole medicine cat with very little training. After the impostor is defeated, Alderheart and Jayfeather return to ThunderClan under the acting leadership of Squirrelflight. After his mother is kidnapped by Ashfur, Alderheart believes that she wouldn't have gone willingly, and is later sent to act as RiverClan's temporary medicine cat by Graystripe.

Alderheart is a kind, loving, loyal and nervous tom.[20] As an apprentice, Alderheart tends to become anxious when he is put in difficult situations and often doubts his own abilities when he compares himself to other cats.[21] He is deeply compassionate and naive, and he shares a strong connection with StarClan.[source?]


Squirrelflight and Bramblestar

"Alderkit knew how much his mother adored him and his sister. He was only a kit, but he understood that Squirrelflight was old to have her first litter, and he remembered their shared grief for his lost littermates: Juniperkit, who had barely taken a breath before he died, and Dandelionkit, who had never been strong, and who had slowly weakened until she also died two moons later. Sparkkit and I have to be the best cats we can be for Squirrelflight and Bramblestar.'"
―Alderkit thinking about his mother The Apprentice's Quest, page 16
Alderheart feels lucky to be the son of Bramblestar and Squirrelflight.[22] Bramblestar is affectionate and comforts his son, valuing them as cats.[23][24] Squirrelflight also adores her kits, and is very protective of them due to the fact that two of their littermates, Dandelionkit and Juniperkit, died soon after birth.[22] She is very proud of both Alderheart and Sparkpelt, and the great Clan members that they have become.[24] Alderheart is sometimes frustrated at Bramblestar when his father does not act on prophecies as quickly as he hopes.[25]


Alderheart: "You didn't care how I felt about SkyClan. Or that I've been worried about the prophecy or that it might be embarrassing to need saving from a kittypet! You're always so sure of yourself—you act like everything you do is okay, and sometimes it's not okay!"
Sparkpelt: "I know you wanted SkyClan to stay. But that doesn't mean I had to agree. I can have my own opinion. And of course I care that you're worried. But you're right. I guess I've been too caught up with Larksong to take the time to talk to you about stuff that's important. And I'm sorry I saved you from that fat kittypet... I'm not sorry exactly. I wasn't going to let you get your fur ripped off. But I trained as a warrior and you trained as a medicine cat. But if I was bleeding to death right now, you'd save me, wouldn't you? Because that's what you do. You save cats. I hunt and fight."
Alderheart: "I'm sorry. I know I'm being oversensitive. And you are allowed to have your own opinions. Even if they're wrong."
Sparkpelt: "I'm glad you're sensitive. It makes you a great brother."
—Sparkpelt and Alderheart Darkest Night, pages 197-199
Alderheart wishes he had the confidence of his sister. She is much more eager and outgoing than him, and he is sometimes overwhelmed by her energetic attitude.[22] Alderheart thinks she is funny, smart, and an amazing warrior.[26] Sparkpelt thinks that Alderheart's sensitiveness makes him a great brother.[27]


Twigkit: "They said I was just an ordinary cat. But if I'm just an ordinary cat, the Clan won't want me anymore. So I had to prove I was special."
Alderpaw: "Of course you're special! StarClan led Needlepaw and me to you. And the Clan will always want you. You're one of us now, and nothing will ever change that."
—Twigkit and Alderpaw when he finds her by the lake Thunder and Shadow, page chapter 6

"Alderpaw felt good [...] to know he had this cat’s respect. He knew he shouldn’t like Needlepaw as much as he did. She’s from another Clan, and she breaks rules all the time, and she’s rude about senior warriors . . . but she’s fun, and different, and she’s really good at hunting and fighting. And she always says exactly what she thinks.'"
―Alderpaw about Needlepaw The Apprentice's Quest, page 104
Despite their clashing natures, Alderheart liked to spend time with Needletail. He enjoyed how she always spoke her mind, and how she was different, like him. Even though he knew that she broke the rules all the time and was from another Clan, he couldn’t resist seeing her.[28]


Alderheart: "I'm going to miss having you around camp."
Velvet: "I'll miss you, too. But I know there's no way we could be together. We lead such different lives. I can't stay here, and I know you have responsibilities and can't leave your Clan."
Alderheart: "Thanks for understanding, Velvet. I'll never forget you."
Velvet: "Good-bye, Alderheart."
