Ivypool is a loyal ThunderClan she-cat who would always at least try and prove her loyalty. She didn't remain loyal to the Dark Forest even though she didn't listen to the Three when they told her that she shouldn't trust Tigerstar at first. Ivypool would even kill a medicine cat to look evil amongst the Dark Forest warriors just for the sake of all the Clans even if it was bad.
Some fans may find Ivypool a little annoying since she was so jealous of Dovewing. But Ivypool just wanted attention like Dovewing. Ivypool wanted to be with her sister, but Ivypool would just be shoved to the side since Dovewing was "special". Of course, Dovewing was special, I'm not implying that she wasn't, but cats and fans should pay attention to Ivypool as well. She risked her life in the Dark Forest to spy for the Three. Ivypool should get more credit for her actions like Dovewing or at least more.
Ivypool's jealousy eventually turned into rage. Her sister got to go to Firestar's den and she got to go on special missions without her. How would you feel if your sibling or close friend got special treatment and you were always left behind?
Ivypool, overall, is an extremely loyal she-cat and would do anything for her Clan. She'd even die saving her sister, Dovewing.
