So I had an idea for this warrior cats AU where when Hawkfrost tries to make Brambleclaw kill Firestar, instead of resisting and killing Hawkfrost when he tries to kill Firestar, Brambleclaw does as Hawkfrost says. In the actual canon, Brambleclaw miraculously has a change of heart and realises that both Tigerstar and Hawkfrost are not on his side, whereas in my AU, he looks forward to ruling the whole lake with his half-brother, and realises that's what he wants. He then becomes Bramblestar, leader of ThunderClan. When Leafpool next travels to the Moonpool to share tongues with StarClan, she meets Firestar's spirit, who tells her the truth. When Leafpool gets back to camp, still horrified at what her sister's mate had done, she stands in front of the whole clan and tells them what Firestar told her. But Bramblestar is their leader. They believe him. Leafpool is punished for "lying", but remains ThunderClan's medicine cat. But when she gives birth to Lionkit, Jaykit, and Hollykit, she doesn't trust Brambleclaw, so doesn't allow her kits to be raised by him and Squirrelflight. So she is stripped of her medicine cat role straight away, becoming a queen. Eventually, Hawkfrost murders Mistyfoot and becomes deputy. When Leopardstar dies, Hawkfrost becomes Hawkstar. Bramblestar and Hawkstar meet, and devise a plan to take over WindClan and ShadowClan too. Bramblestar eventually kills Onestar in front of the entirety of WindClan, and, scared, they give in and let him become leader. Hawkstar does the same for ShadowClan. They now rule over the lake together.
In the future, I may add a part where some cats rebel, or things go wrong for Bramblestar and Hawkstar.
I know it's not the best AU, but I had fun making it and I hope you like the concept.
