A prince by birth, he was cursed by a mysterious Enchantress as punishment for his selfish and cruel nature. Only by loving another and earning their love in return can the Beast free himself and those affected by the spell in the castle before time runs out.
Brooding, conflicted, intelligent and, initially, self-centered. He fits the bill, more so than his animated counterpart. His song, "Evermore", details how he follows the archetype.
Beast is incredibly kind of witty and has a very dry, English, sense of humor. The storyline also expands on his backstory; a flashback confirmed that his kind-hearted mother died when he was a child, leaving him to be raised by his crueler father, giving him his cruel nature as a result.
The years passed and as soon as Belle showed up in his life something has changed within him. He started to realize and feel some things he never felt before. Belle teached him to be kind, sweet, sympathetic and finding himself.
Beast learnt one of the greatest gifts of life, to love and be loved in return.
Beast is not completely brutish despite what his shape suggests. As shown in the battle with Gaston, Beast did not attack Gaston outright, instead, he relied on bold risks, patience and cunning to avoid Gaston's attacks and gain the upper hand. As a side effect of the curse, he was somewhat primal and had a habit of animalistic behavior, from serious social regressions like growling and roaring when angry to arbitrary, slightly humorous traits like forgetting his table manners. These traits also liken him to that of an untamed animal towards strangers.
The film's commentary also implied during the wolf attack scene that he was suicidal, or at least did not value his life too strongly, due to the hopelessness of ever breaking the curse. This was further supported in where Beast, after saving Belle and Chip after they were trapped in a very serious snowstorm, thanked Belle for saving his life, as her presence caused him to realize his own life was not "meaningless" after all.
