King Harold is one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the Shrek franchise.
Harold was born a frog who lived in a pond. One day, he met up with the Fairy Godmother, who allowed him to pursue his dream of marrying and loving Princess Lillian, by making him human. Their first date was in the night and their first kiss made him human. After the death of Lillian's father, he became the king and married Lillian.
Years later, Fiona was born, but she had a curse that made her an Ogre at night they later told The Fairy Godmother and she told them to lock the princess in the tower so she wait can have a kiss from her son Prince Charming to break the curse would come to kiss her and be free from that curse. Rumpelstiltskin was close into getting King Harold to sign a Magical Contract in order to supposedly remove Fiona's curse, however, just as the king and queen were about to sign it, he was told that Fiona was rescued.
At the beginning of the film, Harold doesn't like Shrek at all and is against the idea of Fiona marrying him, so he starts acting very antagonistic towards Shrek. He and Shrek argue at the dining table during a feast to celebrate the return of Fiona thus, destroying the feast.
He hears Shrek and Fiona having an argument, and blames Shrek for everything, even though he was being cruel to Shrek. Then, he was taken in the Fairy Godmother's carriage where she told him that he must have Shrek killed so her son Prince Charming can marry Fiona and become the king.
Later on, Harold reluctantly goes to the Poison Apple and hires Puss in Boots to assassinate Shrek, but this fails as Puss becomes quite fond of Shrek for not killing him despite the fact that he tried to kill Shrek and becomes Shrek's second sidekick.
When Fiona asks where Shrek is, Harold (unaware his plan backfired) tells Fiona that Shrek has ruined her and tells her he's thinking of what's best for her. Later that night, Fiona tells him she had been thinking about what he said and decided to "set things right" which Harold took to mean she was going to leave Shrek. Fiona reveals that in fact she is going to leave her parents and return home with Shrek. That night, after Shrek and Donkey drink a magic potion, Fiona faints (because of the potion) just as she is about to leave and changes back into a human.
Harold was happy that his daughter is human again and that she is with Prince Charming. He begins to feel extremely guilty when he sees how unhappy Fiona is. Harold was ordered by the Fairy Godmother to put a magical love potion into Fiona's tea so she can kiss Charming and love him. Harold spikes a cup of tea with the love potion and goes to give it to Fiona. After a brief conversation with her, Harold sees that Fiona is in fact genuinely in love with Shrek and he decides at the last minute not to give her the potion, knowing it will cost him greatly. The Fairy Godmother tried to cast a spell on Shrek (which most likely causes a human being to reverse with the initial form, as Shrek is a human at the time or possibly to kill him), but Harold dives in front of Shrek, saving Shrek, turning Harold back into a frog. He then apologizes to Shrek and Fiona for his past behavior and gives them his blessing.
Shrek the Third
King Harold sadly dies of sickness so Shrek becomes the new king of Far Far Away. Then the King was dying and so he called Queen Lillian, Shrek, Fiona, Donkey, and Puss to his room to talk to him. The King almost died twice, but he was told that if Shrek doesn't want to be king, then he must find his nephew Arthur Pendragon to become the next heir to the throne. King Harold then passes away and is buried in a foot locker box. He was then sent away in the pond.
Shrek Forever After
During the Ogre Triplets' party (the end-credits scenes), King Harold appears shown in a self-portrait (in the picture, he makes various expressions including a smile); proving he still remains, this time as a spirit. He makes a jealous glance when he sees Lillian dancing and flirting with an ogre.
