The arrogant hunter who wants to marry Belle is Gaston.
Gaston is the principal human antagonist of Disney's 1991 animated film. He is introduced as a celebrated hunter and village hero whose confidence has curdled into vanity, entitlement, and contempt for anyone who challenges him. He assumes Belle should accept his proposal because of his looks and social standing, but she rejects him.
The character was created specifically for Disney's animated adaptation rather than being a central figure in the earliest versions of the French fairy tale. Screenwriter Linda Woolverton shaped him as a “blockheaded suitor,” giving Belle a human antagonist who contrasts with the Beast's capacity to change.
Gaston is often confused with LeFou because the two appear together in Gaston's musical number. LeFou is his admiring, comic sidekick, not the suitor pursuing Belle. Maurice is Belle's inventor father, and Lumiere is one of the enchanted castle servants. Gaston's obsession eventually leads him to organize the villagers' attack on the Beast's castle.
