No I doubt it. Because he is a fair leader.
Whitetail and Onestar did not become mates in the Warriors series. Whitetail is a warrior of ThunderClan and Onestar eventually became the leader of WindClan, but they did not develop a romantic relationship in the books.
Yes, Hollyleaf hates Breezepelt because his and her father are both Crowfeather, but Breezepelt and Crowfeather are in WindClan.
She is actually the half-sister of Breezepelt. Breezepelt's mother is Nightcloud, and his father is Crowfeather. Hollyleaf's father is also Crowfeather, and her mother is Leafpool.
Onestar
Breezepelt's grandmother on his Father's side is Ashfoot. His grandmother on his mother's side is unknown.
Breezepelt dies during a battle when he is caught in the collapse of a tunnel. His injuries are severe, and despite receiving medical attention, he succumbs to his wounds.
He hasn't died yet, but he has to eventually!So read omen of the stars
status unknown
Onestar
Crowfeather has 3 sons. He dosent hate breezepelt he just will never love him or be proud of him (crowfeather only had breezepelt to prove his loyalty to windclan) but he will always defend breezepelt in battle, he dosent hate breezepelt but breezepelt hates him. Breezepelt has always tried to make Crowfeather proud of him but has failed resulting in breezepelt hating his father. He is also very unsure of his fathers loyalty to windclan after he found out that crowfeather has kits in thunderclan. As for his other two sons (Lionblaze and jayfeather) he dose not quite hate them but he will never agnolage them.
No, the reason why is because he loved Leafpool and he didn't love Nightcloud and Breezepelt was his and Nightcloud's kit.
They had many arguments, but Breezepelt and Crowfeather never had a battle. Not yet anyway.
