Role in the Series
She makes her debut appearance in "Sidekick Clio", where she is first seen at Hildegard's going away party. When Miss Elodie announced they were putting on a play called Hello Polly, she instantly auditioned for the play. She showed she has an excellent singing voice and got the part of Polly's sister. She also loved all the magical stage effects Cedric put on and quickly became an admirer of his.
Her first major role is in "The Princess Ballet" where her personality is greatly expanded upon: Like Sofia, she is one of Royal Prep's more academically motivated and achievement-oriented Princesses to the point where people believe she can do anything. She was Royal Prep's most valuable player in a Dazzleball tournament, is Captain of Royal Prep's Gymnastics team, and is the only student in Alchemy Class who was able to turn chocolate into gold. Like Sofia, she's also revealed to be a perfectionist who feels she must get everything right to the point where she doesn't like making mistakes and can take things too seriously and forget the importance of things such as having fun and her reason for being so is the same as Sofia's: A desire to meet the expectations of others and not wanting to disappoint the people she cares about. This is due to her mother, Queen Tessa, being a star student at Royal Prep that is held in high esteem by all who remember her success. Sofia, who completely understands how she feels, gets her to mellow out and gets her to have fun in time to ensure she dances wonderfully.
Her second major role is in "Dads and Daughters Day", Kari first appears at Royal Prep in Miss Elodie's class. After Miss Elodie announces that Dads and Daughters Day is at the end of the week, Kari explains to Sofia what it's all about. She next appears at the Enchanted Animal Park with her father King Oberlyn. Kari and Oberlyn have a fun time. During the canoe part, she gets her father to perform a canoe spin with her. During the Father-Daughter Sing-Along, Kari reveals that her father took her out for midnight tea when she was three years old to help her get over a fear of the dark she had at the time. Disaster strikes when King Henrik takes a Pelicant egg for Hildegard to take back as a souvenir despite Miss Elodie's warnings. This causes the Pelicants to get angry and attack the group chasing them into a hollow tree. When Amber tells Hildegard that it's her fault for demanding the egg, Kari agrees with Amber and reminds Henrik that it's also his fault they're in this mess. They get saved by Sofia and King Roland who returns the egg to the Pelicants.
