The Beast is a character who has been cursed. He is a prince who has been cursed because an enchantress realized how selfish and that there is no love in his heart. The only way to break the curse is love another and to be loved in return- because who would love a beast? The entire castle ends up being cursed. That is basically the prologue of Beauty and the Beast.
Beast does at first imprison Belle’s father, but Belle takes his place. The Beast over time has fallen into despair because he felt like the curse could never be broken. Even Belle saw that there is no love in his heart. But she is now imprisoned in his castle and has been given on rule- “not to enter the West Wing”. Little did the Beast know the impact Belle would have on his life. Over and over again, the staff, who are now things like teacups and clocks and candles, have told him that maybe Belle is the one to break the curse, but he doesn’t believe them on bit.
Things start to change for the Beast when Belle enters the West Wing. This is when Beast loses his temper and that causes Belle to leave the castle. Beast realizes a big mistake he made, and decides to after her. Beast actually decides to save Belle in this moment and actually saves her from wolves from this moment so now his transformation is beginning. Beast and Belle have this constant argument in the castle ending with Belle telling the Beast that he “should learn to control his temper”. But at least he saved Belle and that did took an act of courage and that did show that he did care a bit about Belle. If he did not, he would not have gone after her.
In “Something There”, both Belle and Beast start to fall in love with love. Beast finally has some kind of love in his heart. The love he has in his heart is for Belle. Belle is showing the Beast how to love in many ways. In that one scene, through the enchanted mirror when Belle is seeing her father being mistreated by her townspeople, Beast lets Belle go. So at least he has fallen in love with. So he went from a selfish and unloving prince to a courageous prince and his transformation happened because of Belle. He at least let Belle go even if it might mean staying a Beast forever. Gaston does make the townspeople believe the Beast is dangerous and it is in that moment that Belle realizes just how much she cares about the Beast and hurries back to warn him. Beast fights off Gaston to protect Belle and soon enough the spell is broken.
I love characters with drastic transformations, but not for the characters who are villains or antagonists. Beast proves that Beauty comes from within in. Beast was ashamed of his appearance and that no one would love him. Belle taught him love. After falling in love with her, he had the courage to let her go and the courage to protect her when she came back.
