Every character is unique and has his own strong and weak points... Few people are my tops for some part of their personality... Edward, cuz he wants his love to be happy rather he to be happy (and he is totally gorgeous!)... Bella cuz she rarely thinks of herself and is always worried about the others around her... Alice... well cuz she is Alice :)... But my absolute fave is Jacob cuz he stands on his own, impulsive, when he loves someone is ready to do everything for her, even hurt himself, and... well... he is the best :)!!!
It's hard to pick one character that is called someone's "favorite" I believe in each of the different books each character is brought forward making it impossible for one to hate one character. When reading Twilight my "favorite character" was of course Edward, reading New Moon I was really angry at him for hurting Bella so much but I didn't hate him, I, however, started liking Jacob. In Eclipse I was as confused as Bella was with Edward and Jacob. I realized I liked them both. However, I hated Rosalie, yet in Eclipse after hearing her story and understanding why she didn't want Bella to become a vampire I started to appreciate her more, and actually warm up to her character. You also got a look in Jasper's story and each character was developed greatly. In Breaking Dawn, I believe that Renesmee captured the heart of all the readers. So all in all, it is difficult to choose, in every book, there is always a better development and understanding of every character.
It is really hard for me to pick , when it comes to Twilight characters, because they are definetely all so vivid, and pretty much like real life people(well. except the little part that some of them are vampires, and others wolfs). But if I have to choose I would say Jasper Hale!!! I really adore Alice(and I somehow am like her), but if all fans could look it at that angle- he is extremely strong and I`m mostly referring to his mental power. He is what we girls like to call "The dangerous type"-with all hi scars, it`s actually pretty attractive for almost every woman. Besides he has impeccable manners and is so caring and loving towards Alice.And I have great solidarity for him , because an year ago I was making my first steps into vegetarianism, and know how hard it can be to restrain yourself.He`s great(and thank god for every male fan who shares that opinion!)
