"I have my own camp now, and my own cats. My future lies with them, not you. [...] You will always be my father. But you have to let us all be the cats we want to be. I can't come and live with you. I must find my own path."
— Thunder to Clear Sky about leading his own camp in A Forest Divided, pages 315-316

Thunderstar, also known as Thunder, is a ginger tom with amber eyes[1] and big[7] white paws.[1]

Thunderstar was the first leader of ThunderClan in the forest territories. He was born to Storm and Skystar alongside two siblings, though only he survived after a Twoleg den collapsed overtop of his mother and siblings. He was given the name Thunder and was disowned by Clear Sky, thus Gray Wing adopted him as his own and brought him to live on the moor. Hawk Swoop adopted him, and Lightning Tail and Acorn Fur became his adopted siblings. Yearning to live in the forest, Thunder joined his father's camp; however, after growing frustrated with Clear Sky, he left to the moor with Frost after the white tom was exiled. Though he rejoined his father after Tall Shadow's group split, Thunder left to make his own group and grew close to Star Flower. He was very hurt after her betrayal. After having his group renamed ThunderClan, he gained nine lives and became Thunderstar. He named Lightning Tail as his first deputy and became mates with Violet Dawn, having four kits, Lightning Stripe, Sleek Fur, Feather Ear, and Shell Claw, and fostered Blue Whisker. After his death, he was succeeded as leader by Owl Eyes and ascended to StarClan, guiding his Clanmates for moons to come. He also appeared at Pinestar’s leadership ceremony and gave him a life for making difficult choices.

Dawn of the Clans

"You wanted me to be cruel, like you! But I'll never be cruel!"
―Thunder to Clear Sky The First Battle, page 232
Thunder is born unnamed to Storm, a rogue, and Clear Sky, along with two other unnamed kits. When the Twoleg den that Storm gave birth in collapses, it kills her and Thunder's two siblings. He is discovered soon after by Gray Wing and Turtle Tail and is named Thunder in remembrance of his mother, Storm, and also the tragedy that unfolded when the Twoleg den collapsed. Gray Wing attempts to take Thunder to Clear Sky's camp, but Clear Sky rejects his son, not wanting to harm another cat he cared about. Gray Wing decides to become Thunder's adopted father and takes him back to the moor camp. Hawk Swoop offers to be his adopted mother, since she is already nursing Acorn Fur and Lightning Tail. Despite being raised on the moor, Thunder's heart longs for the forest. When Clear Sky arrives at Gray Wing's camp and asks Thunder if he wants to join his real father's camp, Thunder is a bit hesitant at first, but after questioning Clear Sky, he leaves Gray Wing's camp to be with his father.
As Thunder stays with Clear Sky for a while, he learns that he doesn't particularly enjoy being in his father's group. Clear Sky is extremely critical of Thunder, and the two cats frequently butt heads when it comes to making decisions. Clear Sky makes the decision to banish Frost because the rogue has a severe injury, and he tells Thunder to leave him at the edge of the forest for the maggots. Thunder refuses and leaves Clear Sky's group, horrified at his father's cruelty, and takes Frost with him to Gray Wing's camp. Angry, Thunder claims that he doesn't have a father anymore.
Back at Gray Wing's camp, Thunder is initially concerned by the cats battle training, realizing they were prepare to go to war with his father. Realizing he has no choice, Thunder participates in the training. When Turtle Tail's kits are missing, Thunder and Lightning Tail try to find them in the Twolegplace, believing their father, Tom, stole them. However, they instead find Turtle Tail's body and discover she was killed by a monster on the Thunderpath. Thunder brings the grave news to Gray Wing who mourns for his mate.
Thunder joins the meeting with the other leaders at Fourtrees which soon unravels into a deadly battle. Thunder is horrified by his father's alledged enjoyment of killing and screeches for the fight to stop. Fortunately, the spirit cats of their fallen friends appear and demand the cats to unite or die. Gray Wing steps down as leader of the group and passes the role to Thunder. Gray Wing believes that he was suppressing Thunder's natural leadership abilities and wants his adopted son to shine.
The spirit cats pass on another message - to grow and spread like the Blazing Star. Thunder is confused by this message, though he quickly runs into Star Flower, who claims to understand the meaning. Thunder quickly falls for her, and as they grow close, Star Flower informs him about the herb the message is referring to, which will also cure a deadly sickness that was ravaging the cats. Thunder explains Star Flower's information to the other cats, but they are unable to retrieve the herb because of One Eye, a rogue who has been wrecking havoc to Clear Sky's group. During the final conflict with One Eye, Star Flower betrays their plan to her father, breaking Thunder's heart.
He returns to his father's group in the forest with several other of his cats, hoping that his father might help him lead. However, he is repulsed when Star Flower and Clear Sky develop feelings for each other. When his father continues to ignore his advice, Thunder decides he had enough and creates his own group in the forest. They settle in a sandy ravine, and he appoints his oldest friend, Lightning Tail, as his deputy.
After Star Flower gives birth to Clear Sky's kits, Thunder visits them. At first, he is envious of his father's visible adoration for his new kits, but he is ultimately pleased the kits would grow up with loving parents. He and Lightning Tail rescue Slash's prisoners, and Thunder is immediately awestruck by Violet. He welcomes her and other loners and rogues into his group. When Slash steals Black Ear, one of Gray Wing's kits, Thunder joins in the rescue efforts. He reunites the kit with his father and stays by Gray Wing's side as he dies. Gray Wing renames the groups into Clans, and Silver Stripe names Thunder's group ThunderClan after its leader.
