King Harold

King Harold is Princess Fiona's late father and Shrek's father-in-law.

King Harold makes his debut in Shrek 2. When his daughter Fiona arrives at the castle with her new husband, he is surprised that they are both ogres. King Harold had secretly made a promise to the Fairy Godmother that her son Prince Charming would marry Fiona. King Harold hires Puss in Boots to assassinate Shrek. King Harold then succumbs to guilt when Fiona finds out that Shrek is not around. Harold at first refuses when the Fairy Godmother asks him to give the love potion to Fiona that will cause her to fall in love with Prince Charming, because he recoils from this invasion of her free will, but he is forced to acquiesce by some dark threat of disclosure; in the event, when Fiona states that she loved the old Shrek (rather the 'new' one that Prince Charming is pretending to be), Harold swaps the cup which contains the potion for his own. At the ball toward the end of the film, Harold protects Fiona and Shrek from a blast of magic from Fairy Godmother's wand. He is finally transformed into his original form of the Frog Prince when he is hit by the Fairy Godmother's magic wand. The wife seems not at all unhappy about this turn of events. After this, he apologizes to Shrek and accepts him into the family, his wife saying that he is more of a man for accepting Shrek and Fiona's marriage than he ever was when he was actually human.
