King Hubert seems to be a fairly jolly character; however, no one knows the whereabouts of his queen. He has one son by her, however, Prince Phillip, and is shown to be good friends with Aurora's father King Stefan. At one point, he becomes angry due to a perceived slight against his son, leading to the beginnings of a fight between himself and Stefan, using fish as the primary weapons instead of swords. However, he comes to see the ridiculousness and hilarity of the scene and quickly makes up with his friend.
King Hubert first appears at Aurora's christening along with his young son, Phillip. He is revealed to be a long time friend of Stefan, as well as the king of a neighboring kingdom. He and Stefan decide to betroth their children, Aurora and Phillip, in the hopes that they will marry and unite their two kingdoms.
16 years later, he is seen at Stefan's castle, awaiting Aurora's return eating in the dining room and he and Stefan quarrel over their children and grabs a fish by mistake trying to strike him with and they burst out laughing when Hubert finally realizes what he is holding. He becomes discomforted when Phillip reveals that he has fallen in love with a peasant girl, and intends to marry her. However, neither know that the peasant girl is actually Aurora, who has been in hiding because of the threat of Maleficent's curse.
Hubert attempts to tell Stefan of his son's plan, but falls into an enchanted sleep courtesy of Flora, Fauna, and Merryweather, who have decided to make everyone sleep until Aurora awakens. However, Hubert's words as he falls asleep help Flora to realize that Phillip was the young man that Aurora had met earlier and fallen in love with in the woods. As a result, the fairies return to the cottage to find that Phillip has been imprisoned by Maleficent, to prevent him from breaking the curse.
Once the curse is broken, Hubert awakens and attempts to tell Stefan of Phillip's intentions. However, he does not finish as Phillip descends down the staircase arm in arm with Aurora. He is confused by the scene but appears to be happy regardless.
Hubert is one of the characters from Sleeping Beauty that return in Disney Princess Enchanted Tales: Follow Your Dreams. He attends a Royal Conference along with Phillip, Stefan and Queen Leah, in which Hubert is due to give a speech. However, Hubert realizes he has forgotten his speech at Stefan's castle only when he is already at the Royal Conference. Hubert tries to find it everywhere until the fairies arrive and deliver him his speech. Hubert is next seen at the end of the film, attending a meal organized by Aurora.
King Hubert does not appear in the film Maleficent, but he is mentioned by his son Phillip under the name King John. King Henry's design also somehow seems inspired by Hubert's.
While not making any viewable appearances in the Disney Parks and Resorts, Aurora has mentioned that he attends the EPCOT Food and Wine Festival, eating at all the restaurants.
- His appearance is quite similar to The King from Disney's 1950 feature film Cinderella, because both of the two are half bald, obese and have a mustache.
