What an interesting question. I'll answer with animals. Hester is a brave, loving and loyal woman, so I would choose a lion for her. Dimmesdale is a weak, cowardly man who poses as a man of God, but cannot admit his own sin. He hides behind his vocation as a minister while letting Hester bear the brunt for their shared sin, so I would choose an animal for him that is nocturnal - like a possum or a raccoon or maybe even a mole. Chillingsworth is an evil, plotting and vengeful man. He pretends to be something he is not, and he is also consumed with revenge, so I would choose a wolf for him, or perhaps a jackal or hyena.
