SPOILERS!!! Yes, I know about Mapleshade and Darktail, but I haven't reached their point in the books, so they're not here. Tigerstar- He killed Redtail to become deputy, then tried to kill Bluestar to become leader. After failing and being exiled, he somehow became ShadowClan's leader, inviting BloodClan to the forest (and getting himself killed). Later, in Omen of the Stars, he starts training Clan cats for the great battle with his fellow Dark Forest members. Hawkfrost- Tigerstar's son, and no less hungry for power. He conspired with Mudclaw to start a rebellion against Onestar, and tried to make Brambleclaw kill Firestar. Sol- It's a bit hard not to hate him when he's literally like "Stop believing in StarClan." It is unknown whether he wants to intentionally destroy the clans, but he definitely has a reason to come striding into the ThunderClan camp to announce 'a great darkness', and later tries to make ShadowClan stop believing in their warrior ancestors. It is later revealed that the majority of his knowledge comes from Midnight the badger. Brokenstar- The fox-heart who leads kits to their deaths by making them apprentices before they are 6 moons old. He also tries to invade ThunderClan after he and some of his clanmates are exiled from their own Clan. His mother, Yellowfang, feeds him deathberries soon after to stop him conspiring with Tigerclaw. Darkstripe- Tigerstar's loyal follower and puppet; he tries to kill Firestar, Stonefur, and Sorrelkit, each for a different reason. He plots with Tigerstar in the Dark Forest. Ashfur- He just went too far trying to make Squirrelflight love him. When she mates with Brambleclaw instead, he traps her 'kits' in a forest fire. Squirrelflight reveals that Jayfeather, Lionblaze, and Hollyleaf aren't hers in order to save them (Which basically makes them hate her). He is later murdered by Hollyleaf. Scourge- The leader of BloodClan, formerly known as Tiny, he gains power in his group of rogues. He is the killer of Tigerstar, ripping him open so viciously that he loses all nine lives at once. ---------------------------Others------------------------------ Stoneteller- Keeping Stormfur prisoner because of the belief that he would save the tribe isn't necessarily a bad thing, but it sure made Stormfur miserable enough. Mudclaw- He started a rebellion against Onestar because of his belief that he was the rightful leader of WindClan. He also started a battle, after which he was killed by the falling tree that formed the bridge to the island. Ivypool- As Ivypaw, she trains in the Dark Forest with Hawkfrost and 'The Clanmates'. She is jealous of her sister for getting all the attention, so she trains to become a better warrior in the Dark Forest, not knowing that they mean to destroy the Clans. Breezepelt- He and Brokenstar try to kill Jayfeather together, failing. Overall, Breezepelt is bitter toward his equally unfriendly parents, but he trains in the Dark Forest. And I think he knows that they want the Clans gone.
