Major is not given a distinguished personality other than that he is a loyal friend of Cinderella. While he is not treated properly by Lady Tremaine or her daughters, Anastasia and Drizella, Cinderella offers enough love for him. It indicates that he dreams of becoming royalty like Cinderella. Evidence of this appears during her Fairy Godmother's visit where he was excited about becoming the horse for the carriage (although he was happy with becoming a coachman instead) and when he led the palace horses with pride for Cinderella's honeymoon.
Later, Major sleeps in the barn with Bruno. They wake up to watch Cinderella run out into the garden wearing a torn dress that was destroyed by Anastasia and Drizella due to the beads and sash they threw earlier. They follow her, looking sad for her as she is crying about not going to the ball. Soon, a fog with sparkling stars heads for her, which turns out to be the entrance and appearance of her Fairy Godmother. Major expects he will pull the carriage, but instead, he is turned into a coachman by the Fairy Godmother in order to take Cinderella to the ball, much to his joy and excitement. At the stroke of midnight, when the spell is broken, he is turned back into his true form. With Cinderella, Bruno, and the mice, he runs behind the bushes, away from the palace guards who go past the pumpkin and smash it. Major is shown to be happy that Cinderella had fun at the ball, dancing with Prince Charming.
At the film's climax, Major notices the birds trying to wake up Bruno. This sight as well as their continuous chirping, make him realize that Cinderella is in trouble. He helps them wake up Bruno by whinnying as loud as possible to allow him to scare Lucifer (who has trapped Gus and the key—which is stolen from Lady Tremaine—under a teacup to prevent Cinderella's exit) away from the door to Cinderella's room. Major is last seen pulling her and Prince Charming's carriage as the lead horse, along with their other horses, to take the newlyweds on their honeymoon.
Major briefly appears in Cinderella II: Dreams Come True. In the first segment "Aim to Please", he is one of the horses pulling Cinderella and Prince Charming's carriage. In the second segment "Tall Tail" as the horse, she used to travel out of the castle.
