I'm going to organize this the same way rhythmicmagic did. I decided to combine the heroes with the heroines but my descriptions will be a bit shorter.
Favorite Animal Heroine: Bianca
She reminds me a bit of Aurora as she puts duty over everything. Adding to that, she's also feminine, elegant and graceful. Her caring nature and compassion make her so lovely. Also, Bianca and Bernard are one of my favorite Disney couples.
Favorite Animal Hero: Bagheera
I've always loved Bagheera, he's so humble, mature, smart and caring. He's constantly worried about Mowgli, I think that's really sweet. He wants the best for him and takes good care of him.
Favorite Heroine Friend: Lottie
Lottie is spoiled, self-centered and so funny! Her personality shines through. She is a great friend, she always tries to help Tiana out and doesn't expect to get anything in return. I also adore her wardrobe.
Favorite Hero Friend: Thomas
He's one of those characters I can actually feel bad for. Poor Thomas, he was very inexperienced at the things he had to do and he was just a total mess. And how he becomes more confident towards the end of the movie makes me happy.
Favorite Young Heroine: Alice
Alice is a really fun and interesting character. I love how she wants to live in a world of her own. She finds most pleasure in the fantasy world she created. I also love her polite, well-spoken, know-it-all attitude.
Favorite Young Hero: Taran
I haven't watched The Black Cauldron in a very long time so I might be wrong on some things. But out of all young heroes, Taran is still my favorite because I love his desire to prove his worth and how he has to search for it throughout the whole movie. He is heroic, adventurous and is just a great kid.
Favorite Non-Princess Heroine: Nani
Nani struggles, works hard and tries her best to take care of Lilo, their relationship is just the best. They drive each other insane but they really do love each other. I can relate to her in the sense that I have such an annoying little brother, he's almost 17 now but he still acts like Lilo. When Nani had just lost her job, she didn't blame Lilo a single bit and just tried hard looking for a new one. So yeah, Nani is an inspiration.
Favorite Non-Prince Hero: Kuzco
I'm not going to point out all the bad in Kuzco because the positives definitely outweigh the negatives. Plus, the way he learned the true meaning of friendship is actually believable to me. To add to that, he just has that pizzazz to him and he's one of the most hilarious Disney characters ever! I ship him with Chel if you were wondering, they're one of my favorite crossover couples.
Favorite Pixar Heroine: Violet Parr
I usually love characters who grow out of their insecurities because I can see myself in them as cheesy as it sounds and I still find them interesting. Violet didn't feel like she fit in with the rest of the crowd and she really wanted to. But she becomes more proud of who she really is towards the end of the movie.
Favorite Pixar Hero: Mike Wazowski
Mike became my favorite when I finished watching Monsters University. Not that his character was much different from Monsters Inc., I could just feel for his character more. He worked and studied really hard but still failed countless times. How he doesn't let all the negativity bring him down and always tries to improve is incredibly admirable.
