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, announced by the royal herald. It is revealed that Hubert was the 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. He and Stefan quarrel over the future of their children and Hubert grabs a fish by mistake trying to strike Stefan 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 Hubert, Stefan, or the others realize that the peasant girl is actually Aurora, who has been in a hiding place 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 asleep 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 within the woods. As a result, the fairies return to the cottage to find that Phillip has been imprisoned by Maleficent, who tries 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 as he was unaware that Aurora is indeed "a peasant" in disguise.
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, along with Stefan, Leah, Phillip, the fairies, and Lord Duke, attending a royal banquet organized by Aurora.
King John, along with his wife, Queen Ingrith, appears in the sequel. He is portrayed by Robert Lindsay. Unlike Ingrith, he seeks to establish peace between Ulstead and the Moors. Following his son's engagement, John and Ingrith hold a banquet, to celebrate the young couples upcoming nuptials. During the dinner, tensions rise while Maleficent and Ingrith discuss the fatalities on their respective sides, each claiming the other is responsible. When Maleficent loses her temper, Ingrith enacts her secret plan to overthrow the king, by cursing him with a spindle and blaming Maleficent. Now under a sleeping curse, Phillip urges his mother to kiss John, falsely believing in their relationship, but it doesn't work, as Ingrith secretly despises her husband for desiring peace. The King's cursed state sets off the motions, resulting in a war between Ulstead and magical beings of the Moors, as well as the Dark Fey.
Afterward, Prince Phillip ends the war between Ulstead and all the fairies and Ingrith is turned into a goat for her tyranny, Maleficent destroys the spindle and breaks the curse, awakening the king. He is later seen attending the wedding between Aurora and Phillip at the end, telling Phillip how proud he is of him for succeeding in achieving peace between Ulstead and the Moors.
- While not making any viewable appearances in the Disney theme parks, Aurora has mentioned that he attends the EPCOT Food and Wine Festival, eating at all the restaurants.
- There was originally a scene that could have taken place in the beginning where King Hubert and King Stefan argue about the future of their children and compare portraits of their young children, a song called "It Happens I have a Picture" (heard in The Legacy Collection: Sleeping Beauty), sung by Bill Thompson and Hans Conried. While Conried was possibly switched into voicing the herald as Taylor Holmes took over the voice role for Stefan, Bill Thompson was finalized as Hubert in the final film.
