what happened was yellowfang gave birth to 3 kits, one was born dead, and the she-cat was fine at first but soon had trouble breathing and died, yellowfang thought that was her punishment for falling in love when she was a medicine cat but her real punishment was not that the she-cats died, but the tom survived.
He blamed Yellowfang for killing some kits even though he did, he tried to steal kits, and he led the dark forest against the Clans.
Yellowfang had three kits: Brokenstar, Hopekit, and Wishkit.
Stoneclaw, Mosspaw, Volepaw, Mosskit, two unnamed she-kits that are Brokenstar's sisters, and Lizardstripe die.
Raggedstar Mosspaw Volepaw Lizardstripe Two unnamed she-kits (Brokenstar's sisters)
Brokentail framed her for killing Dawncloud's kits, so she was exiled. She then became a rouge, until she was found by ThunderClan
They didnt say
He has 4. Leafpool:3 kits Feathertail: 0 kits Nightcloud:1 no leafpool had no kits she didnt want to break the warrior code.she ran away with him but didnt have any kits with him!!! You're not far in the books are you?....~Brightsong
Brokenstar exiled Yellowfang from ShadowClan because she opposed his cruel methods of leading the Clan, which included training kits too early and driving out the elderly and weak cats. Yellowfang's strong sense of justice and refusal to support Brokenstar's actions led to her exile.
ShadowClan never found out, so she wasn't punished by them. However, the fact that she gave birth to Brokenstar/Brokentail was punishment enough.
The kits that ShadowClan stole from ThunderClan in "Into the Wild" are Mistykit and Stonekit. They were taken by Clawface and given to Brokenstar in exchange for ShadowClan's loyalty.
Yellowfang fed Brokentail deathberries to exact revenge for his role in killing her kits and spreading lies about her. It was a drastic measure to punish him for his crimes and bring justice to her offspring.
Brokenstar was the former leader of Shadowclan, he is best known for killing his own father, Raggedstar, for driving Windclan from the forest, and for going against the warrior code by making kits younger than 6 moons into apprentices. He is also indirectly responsible for the death of Spottedleaf, in that Clawface was sent into Thunderclan camp to steal kits, and he killed Spottedleaf in the process. It should also be noted that Brokenstar was the son of Yellowfang, who eventually killed Brokenstar to put an end to all the trouble he caused. ________________________________________________________________ Brokenstar is most famous for driving out WindClan, only to be brought back by Firestar and Graystripe on their first warrior mission. Brokenstar allied with Tigerstar and a band of rouges while he was imprisoned in the ThunderClan camp. He finally died when his mother, Yellowfang, killed him with deathberries. In The Fourth Apprentice, it is suspected that he is an ally of Tigerstar and Hawkfrost because Breezepelt is fighting alongside a "brown tom with a twisted tail." It hasn't been confirmed as of the day I'm typing this, but is is most likely him because Jayfeather doesn't know who he is and he is one of the only brown and evil tom.
