Prince Hugo is a prince and flying horse racer in Sofia the First. He is voiced by Colin Ford in season 1 and Grayson Hunter Goss in season 2. He dislikes that Sofia, as a princess, is competing in the flying derby and he antagonizes and teases her every chance he gets. He bullies James as well. He appears in "Just One of the Princes" and has a cameo appearance as Princess Cleo's partner in "The Shy Princess".
In The Flying Crown, it is also revealed that his personality stems from having to live up to his family's legacy and feeling frustrated at failing to do so. James and Sofia were going to ride for Royal Prep in the flying derby championships against the Junior Knights, but James fell and sprained his wrist, so Sir Gillium and Sofia asked Hugo to join her to ride in the championships. Sofia was nice enough to give Hugo a chance and put the tryout race incident behind her, but Hugo refused to work with her because his pride wouldn't let him be anything but number one. Later, Hugo's flying horse Electra told Sofia that everybody in Hugo's family has been cheered for at the flying derby races but not him. This made Sofia realize that Hugo was feeling left out because of that. During the race, Sofia and Hugo didn't show up when they were called to come to the starting line. James got the crowd to sing the Royal Prep cheer for Sofia and Hugo, who listened to the lyrics carefully and finally understood the meaning of teamwork. Hugo agreed to ride with Sofia in the race, and they smiled at each other, showing that they were becoming friends. Sofia and Hugo's opponents, Vaughan and Vance saw this and were jealous of Hugo because he managed to win over a girl. When they had to do the flying slingshot to win, Hugo finally agreed to sling Sofia since he's stronger and she can't sling him too well. When Sofia and Hugo held onto each other's hands. he swung Sofia and her horse around him and slung them to the finish line before the Junior Knights, and they won the Flying Crown. When his brother said they won because he takes after him, Hugo reminded him that it was mostly because of Sofia, who taught him the meaning of teamwork and turned his heart into gold.
In "Lord of the Rink", Hugo revealed that he had a passion for ice-dancing. He saw Sofia having trouble with her ice-dancing, and he showed that he was a very talented ice-dancer. Flora offered to let him join the ice-dance class, but Hugo refused at first because there were no boys in the class. However, Sofia told him that she was the only girl on the flying derby team, and he agreed to join the class. But Hugo kept it a secret from his friends because they thought ice-dancing was a female sport and did his best to get out of hockey practice. Hugo also kept his passion a secret from his father, King Garrick, who doubted that the men in their family ice-danced. It is implied that Garrick barely spent time with Hugo, and he decided to give his son extra attention by becoming the new assistant hockey coach. Because hockey practice and dance class happened at the same time, Hugo tried to be in two places at once, and it worked until his friends caught him in the act. Later, Hugo revealed to his father that he loved ice-dancing and left practice to perform in an ice-dancing recital with Sofia. When Garrick, Sir Henley, and the other boys saw how talented Hugo was, Garrick was very proud of him, and the other boys asked him to teach them how to ice-dance.
