Snow White and the Seven Dwarfs

After her mother's early passing, her father, the King, remarries what is later known as Disney's first villain.

Obsessed with being the most beautiful, the Queen becomes envious of Snow White, who surpasses her in looks.
In her final effort to eliminate her competition, she disguises herself as an old woman and offers Snow White a poisoned apple.

From the outside, the Queen appears to be calm, and sophisticated, but in reality, this facade hides an extremely sadistic, hateful, cold and sinister person.

She is portrayed as ruthless, jealous, and obsessive, and wants nothing more than to be the fairest in the land.
She also has an extreme vanity that makes her utterly intolerant of rivals.
