He and Brambleclaw were with Firestar, who was stuck in a fox trap, and Hawkfrost told Brambleclaw to tighten the trap and kill Firestar, but Brambleclaw killed Hawkfrost instead, fulfilling the prophecy "Before there is peace, blood will spill blood, and the lake will run red."
He claims of not knowing that his warriors participated in Mudclaws rebellion.
Sorry there is no Hawkhead is the warriors series, there is Hawkfrost (Brambleclaw's half-brother and Mothwing's of Riverclan brother.)
He fell in love with leafpool, and helped fight the badgers.
He helped find Crowfeather and Leafpool and then he helped fight off badgers
She fell in love with Crowfeather, for one-that seems to be the most popular part of the book about her.
She was in Shadow Clan. She did have a kittypet problem and her brother Brambleclaw helped her fight them off.
Hawkfrost did not have a confirmed mate in the Warriors book series. He was shown to be manipulative and ambitious, focusing more on his own desires and ambitions rather than forming romantic relationships.
Hawkfrost knew that his father was Tigerstar because Sasha told him and Mothpaw(wing) that Tigerstar was their father. And then Tigerstar probably just started to visit Hawkfrost and that is how he turned out to be so evil.
No, she only plays a part in when she goes to the forest to find Mothwing and Hawkfrost. If you are talking about all books, there is a Manga series about Tigerstar and Sasha.
Midnight: Brambleclaw, Moonrise: Feathertail, Dawn: Squirrelflight, Starlight: Leafpool(Maybe Mothwing), Twilight: Crowfeather, Sunset: Hawkfrost it was also debated whether the cat on Twilight could be Cinderpelt but it can't since Crowfeather is dark gray and cinderpelt is not dark gray. She's just gray
He got his throat slit by his brother. Hawkfrost attacked Brambleclaw and he is pierced in the neck by the stick from the fox trap. Brambleclaw, his Half-brother, never meant to kill him.
He is first mentioned as Berrykit in "Twilight" in the second series.
