|"My poor Devilkit! What happened to him? Has he been murdered?"|
|— Glasswater wakes up to find Devilkit dead in Hidden Prophecies, Prologue|
|Cause of Death|
|Cause of Death:||Killed by Lilykit|
- Devilkit is first seen when the queens of SapphireClan wake up to the sound of a very loud meow. His mother, Glasswater, looks down in shock to see blood gushing out of his neck. She cries loudly, desperately trying to wake him up with licks, but nothing happens. With tears in her eyes she asks the other queens what happened to him, and if he's been murdered. They look around to see Lilykit with blood on his paws and muzzle, who pushes Devilkit away and begins to nurse on Glasswater. Glasswater sobs, telling him he killed her kit, but forgives him, vowing to raise him as her own and teach him that he cannot kill to get what he wants.
- One of the queens expresses sympathy toward Glasswater but then says that maybe Devilkit dying was for the best, as he could have grown to be a terror among the Clans. Glasswater says that she supposes, but it is still a shame. Goldenmask agrees with her, saying that she would be very sad if one of her kits was killed. She then adds that Lilykit will have to be taught a lesson, or they could have a killer on their hands. Another queen says that she doesn't think Lilykit meant it, as rough housing has gone too far many times, and it will so in the future.
- When the banished Lilypaw, now named Darkpaw, comes to a gathering with a dragon and a group of cats to take over the clans, Vanillastar renames him Lillyblossom to get revenge for all the cats he killed, including Devilkit.
- Unidentified kit(s): Status Unknown
- Unidentified Queen: "It is too bad about your little kit, Glasswater, but maybe it was for the best. After all, he might have grown up to be a terror to all of the Clans, and we wouldn't want that, would we?"
- Glasswater: "I suppose not, but still it is a shame!"

- "I thought I exiled you? Oh well. Since I am the Clan leader, I have more authority than you, even though I am a crappy leader, and so I can get my revenge since you killed Lavendarstar and Glasswater and Devilkit and a bunch of other cats! From now on, your name is officially LILYBLOSSOM!"
