Prince James

Prince James is a major character in Sofia the First: Once Upon a Princess. He is a prince and the twin brother of Princess Amber and the older stepbrother of Sofia the First.

Personality
Unlike his sister Amber, James is not at all vain and is very helpful towards Sofia. He is rather easygoing for a prince, sometimes displaying behavior not normally seen in royalty, such as cheering during the flight to school, talking with his mouth full, etc.

He has a normal brother-sister bond with Amber, teasing her that "she wasn't gonna be the fairest in the land" anymore once Sofia came along but out of good-natured humor, though he recognizes Amber's faults enough to tell her that he likes Sofia better than her (although he was just cross with her).

James also has a bad habit of disobeying rules and trying to cover up his messes so as not to get punished, though when he ruined a stained-glass window and Sofia took the blame for him, he felt guilty and told his parents the truth, showing he has a sense of honesty.

At the Tri-Kingdom Picnic, James partners with Sofia and shows two unbecoming sides of himself: He is very competitive, wanting to win the trophy at the games, and is shown to be a bad sport, not taking losing well and bragging about winning so obnoxiously the other princes and princesses, including Sofia, don't want to play anymore. It is only when Sofia shows him what a good sport their father is, playing to have fun, not so much as to win, does James realize how bad his behavior was. He apologizes to the others and they continue the games, and even takes losing well, personally giving the trophy to the winners, Princess Maya and Prince Kalid, and displaying no hard feelings, as well as a promise to be a good sport from now on.
