Hawkfrost is a villain in Erin Hunter's Warriors book series. He is a huge, dark brown tabby tom cat with ice-blue eyes, broad shoulders and a white underbelly.
Return of the Clans
In Return to the Clans he is first seen as a kit with the name of Hawk, later Hawkkit. When his mother Sasha goes hunting, he and his siblings Moth and Tadpole climb into an abondoned Twoleg nest (Human House). It starts to fill with water and Tadpole is able to open the window but slips and drowns in the flood. Hawk then keeps yelling for his dead brother and when he finds out that Tadpole died in the flood, he lets out a yowl of grief.
Moth, Hawk, and Sasha go to a barn which Pine (a rogue) suggests, but they are attacked by cats living there, Hawk's ear getting cut in the process. Quickly, they leave for RiverClan, and Sasha leaves her kits there, but decides Clan life is not for her. In RiverClan he and his sister receive their new names Hawkkit and Mothkit.
In Midnight at the Gathering Leopardstar announces that Hawkpaw and Mothpaw have become warriors with the names of Hawkfrost and Mothwing. His mentor was Leopardstar. When cats from other clans protest Leopardstar tells them all about Sasha and how she left them behind in RiverClan. She says they will not be disloyal just because they were rogues, unlike the past of ShadowClan. Later Firestar tells Hawkfrost that everybody will stop fussing about him and his sister soon. Hawkfrost says that he will try to defend his Clan even at the cost of his life. Hawkfrost is later seen on patrol with the RiverClan deputy Mistyfoot (Later Mistystar) watching WindClan drink from the river, also making sure that they don't steal prey. Hawkfrost says something urgently to Mistyfoot but she shakes her head in reply to whatever he said. The RiverClan patrol greets a ThunderClan patrol consisting Leafpaw and Sorreltail, and Hawkfrost greets them politley. Leafpaw thinks that Hawkfrost reminds her of someone that she knows but she can't make out who it is. Mistyfoot asks if they have seen Stormfur and Feathertail (Two RiverClan warriors) who have gone missing and she is shocked to hear that Brambleclaw and Squirrelpaw (Two ThunderClan warriors) are missing also. Hawkfrost says that they should ask the other Clans if they are missing cats also. The subject later turns to that WindClan has been drinking from the river. Hawkfrost says furiously that they should be drivin off but Mistyfoot says that Leopardstar would not allow that. Hawkfrost calms down but still seems angry. Later at the gathering Hawkfrost asks Leopardstar if he may speak. He reports that he saw WindClan warriors taking fish when they were only supposed to be drinking water. Tallstar gets mad that his clan is accused of stealing, but Leopardstar gets angry also and accuses Hawkfrost of lying. As clouds start to cover the moon, everybody calms down and Firestar asks Hawkfrost it he is sure he is not mistaking what he saw. Hawkfrost admits that he could have been seeing things, he still thinks that he is sure of what he saw.
In Sunset, he is visited in his dreams by Tigerstar,his father. He later lays a trap for Firestar, the ThunderClan leader, so his half-brother Brambleclaw could become leader. Hawkfrost's plan backfires when Brambleclaw kills him. Hawkfrost slides around his half-brother,whispering revenge.
