Billystorm/Main article

Billystorm is a ginger-and-white tom with leaf-green eyes and a broad face.

Billystorm, also a kittypet named Billy, is first seen as a daylight-warrior of SkyClan: a warrior who participates in the Clan during the day, but returns to his Twolegs at night. Leafstar's addition of the daylight-warriors is a subject of oppose, particularly with the other regular warriors. Nonetheless, Leafstar grants him an apprentice, Snookpaw, another daylight-warrior. Regardless of his Clanmates' begrudges, Billystorm is a loyal and dutiful warrior of SkyClan, and even participates on a short journey to help Stick and his cats in a far away Twolegplace. He opens Leafstar's eyes to kittypets, and the two grow close, despite Echosong's initial concerns about Leafstar's duties as Clan leader if she chooses to have kits.

He eventually becomes mates with Leafstar, and is shown as a doting and loving father to their kits: Firekit, Stormkit, and Harrykit. He becomes frantic when his mate and kits are taken by an elderly Twoleg, and assists with the rescue. After the gorge floods, Billystorm considers taking his kits to stay with his Twoleg. When Leafstar discovers this, she banishes him temporarily from SkyClan. After Sol kidnaps his kits, Billystorm decides to remain in SkyClan permanently, choosing to put his new family first.

His kits grow up to be warriors, and Billystorm continues to console and advise Leafstar. He mentors another apprentice, Pebblepaw, and is chosen to lead a patrol to find ThunderClan. Billystorm is killed by badgers, and the group decides to bury him where he'd fallen and to abort the mission. Her mate's death effects Leafstar hard, and his death remained a difficult subject for sometime.

Mistakes

 * He has been mistakenly described with amber eyes several times.
 * In The Ultimate Guide, it is mistakenly said that Billystorm decided to stay in the gorge and become a full SkyClan warrior after rescuing his kits from the elderly Twoleg's den. In the manga, After the Flood, he decides to stay after SkyClan finds that Sol was hiding the kits, which happened a while after rescuing the kits from the Twoleg.
