Dovepaw
The third cat for the prophecy is Dovepaw, daughter of Whitewing and Birchfall.
Lionblaze, Jayfeather, and Dovepaw are all part of the prophecy
Dovepaw is a she-cat.
Ivypaw hates Dovepaw because Firestar listens to her and Dovepaw is singled out like a super warrior.
No, Dovepaw does not die in Night Whispers.
Dovepaw will become a warrior in the 4th book, Sign of the Moon.
The third apprentice is the third cat with powers more powerful then StarClan, and that is Dovekit/Dovepaw. People believed the third cat was Hollykit/Hollypaw/Hollyleaf, but she had no powers, while Lionkit/Lionpaw/Lionblaze could fight in battles, and not get a single scratch on him, Jaykit/Jaypaw/Jayfeather could walk in the dreams of other cats, and read their emotions, and Dovekit/Dovepaw could hear and see what was happinging far away.
Dovepaw's warrior name is Dovewing. Ivypaw's warrior name is Ivypool.
Dovepaw is the chosen one not ivypaw. ( I thought ivypaw was one of the thrre)
Dovepaw and Ivypaws mother is whitewing and the father is Birchfall. Hope you find this answer helpful!!!
In the Fourth Apprentice, Dovepaw helps the Clans by finding the beavers and breaking their dams.
