Gaston is strong and handsome, and is all too aware of this. He is hailed as a local hero, desired by many of the young women of his village (he is even described as “cute, dreamy and handsome”) but he is really boorish, uncultured and egotistical. However, despite these negative qualities, he is far from stupid or brainless as Belle claims.
In this version, Gaston is a perfect example of a sociopath. He acts civil and polite to Belle and never doubts her intelligence, and offered to help Maurice rescue Belle. However, all of these good deeds he does are done purely for his own benefit, and he sees Belle as nothing more than a prize to be won. Also he sees people as nothing more than tools in his plans and discards them when they have run out of use. Examples being, when Maurice refuses to give Gaston his blessing to marry Belle (which was Gaston's motivation in helping Maurice), Gaston leaves him to be eaten by wolves. And finally using LeFou as a human shield in the climax and leaving him to die once he served his purpose.
Gaston is the absolute anti-thesis of Beast. Although Gaston is physically handsome, he is very psychopathic, atrocious, shallow, completely self-centered, not very bright, and thrives on attention. However, when his ego is bruised he becomes a very dangerous foe for Beast, Belle and Maurice.
However, in this film, Gaston will be portrayed as a former soldier prior to his career as a hunter due to a portrait of him standing over fallen soldiers in the tavern.
Gaston is a war hero on top of having good looks and hunting/fighting skills, which goes further in explaining why someone so obnoxious is so beloved and trusted by the townsfolk.
Gaston undergoes this with regards to his villainy, possibly to avoid his animated counterpart gets. In this version Gaston has been harassing Belle for quite some time when the action proper begins, to the point that she avoids him whenever she can, and the villagers' admiration of him is partially out of obligation to his war heroics. He snatches an alms cup from a beggar just to check his reflection in it before his first on-screen conversation with Belle, and in his second conversation tells her that she's doomed to become a beggar herself if she doesn't get married. Later, before he tries to have Maurice institutionalized, he tries to kill Maurice by tying him to a tree in the cold woods and letting him die of exposure at best, the wolves at worst.
Gaston later convinces the villagers that the Beast is a man-eating monster. He locks up Belle alongside her father when he realizes she loves the Beast and subsequently rallies the villagers to join him in storming the castle. Gaston abandons LeFou during the battle. He shoots the Beast with his gun after finding him heartbroken. When Belle arrives at the castle, Gaston gloats, but soon the Beast subdues him after a harsh fight but eventually spares his life and orders him to leave. The Beast leaps across to join Belle, only to be fatally shot from behind by Gaston, mortally wounding him. Before Gaston can celebrate, the footbridge on which he is standing crumbles and falls to his death.
It is also implied that this incarnation of Gaston, he is far more psychotic than the original.
Gaston is a rude, impatient, destructive, vain, egomaniacal, manipulative, narcissistic, and psychopathic hunter who will go to any length to get what he wants, even if it involves bribing or blackmailing others. He is very conservative, narrow-minded, and misogynistic to the extent that he disapproves of women reading because he regards ideas as dangerous to them, and believes that women's only purpose in life is to serve men.
Gaston is a well-loved man. That makes him extremely dangerous -- he has the entire town on his side. Gaston has excellent hunting skill, which makes him popular (especially the butchers). Gaston combines two common Disney villain characteristics -- foppishness and hunting.
Because Gaston is very handsome and muscular, he is also well-respected in the village as he was able to rouse a mob to help him kill Beast. This shows that he is also vengeful, since he suspected that Belle (whom he wanted to marry) had feelings for Beast.
Despite Belle calling him "brainless", he is not stupid, as he can come up with clever plans to get what he wants. In spite of his intelligence, Gaston can be quite impulsive as shown when he tried to grope Belle.
Gaston is slender, extremely muscular, hairy-chested, black ponytailed hair, blue eyes, red polo shirt with gold collar, gold gloves, brown belt, black pants, heavy-action boots.
