Actually, I think Hawkfrost actually did have feelings for Ivypool. I mean, he always watched her and he was her mentor in the DF (Dark Forest) Look for hints in the Omen of the Stars series, cause I swear Hawkfrost loves Ivypool.
Yes, she does. She dies saving Ivypool from Hawkfrost and two other Dark Forest warriors. While Ivypool is busy fighting off the two Dark Forest warriors, Hawkfrost kills Hollyleaf.
Only after 'The Last Hope', when she jumps in front of Hawkfrost to save Ivypool.
Hawkfrost doesn't kill Hollyleaf. Hollyleaf dies in a cave-in caused by a crumbling tunnel while saving Ivypool from an attack. Hawkfrost was killed by Brambleclaw during a battle at the end of the "Power of Three" series.
No, Ivypool from the Warriors series is not inherently evil. She struggles with jealousy and insecurity but ultimately chooses the path of loyalty to her clan and redemption.
Hawkfrost trained Ivypool in the Dark Forest, manipulating her to turn against her own Clan, ThunderClan. He took advantage of her desire to prove herself and gain recognition, ultimately causing her to betray her Clanmates.
No she does not but bumblestripe use to have a crush on her but now he loves dovewing.
No there never was a romantic relationship between Hawkfrost and Leafpool.
Spoiler :) She was because she thought it would help her become a better warrior but ever since Dovewing Jayfeather and Lionblaze talked to her and told her that they're bad and made Ivypool a spy she only does it because of spy missions.
Ivypool's parents are Whitewing and Birchfall. Whitewing is her mother and Birchfall is her father.
No. He is dead. She is alive. He was (and still is) a tyrant trying to take over the forest, and she is just following him.
No because eventually Brambleclaw kills Hawkfrost.
Yes, Hawkfrost did fight Brambleclaw before Brambleclaw killed him. Though, Hawkfrost was blinded by the greed for power and did not have the loyalty of a true clan warrior, and didn't have the strength to win.
