Prince Carlos of Flutterfield is a character in Barbie: Mariposa and her Butterfly Fairy Friends and Barbie: Mariposa & the Fairy Princess. He is voiced by Alessandro Juliani and he is Queen Marabella's book-loving son.
Prince Carlos is exactly like Mariposa as they both don't enjoy parties, but instead, love reading and dreaming about going to different places beyond the safe borders of Flutterfield. At first when he bumps into Mariposa, he gives her the book that she dropped and they both realize that they have the same book. He read it nine times and Mariposa had read it ten times. Prince Carlos was not allowed out in public, so Mariposa didn't know he was the prince. He told her his name was Andreas, the name of the character in the book they read.
He revealed his true identity when he asked her to save his mother. Later, the guards keep him in prison to protect him and do not believe in him when Prince Carlos tells them that the Queen Marabella has been poisoned by Ilios, as Ilios is not thought to exist.
Carlos is able to prove it right when Willa set him free from the prison and followed Henna to her secret hideout. The prince appeared again by helping defend the first line with throwing some glowing thistleburst. After Mariposa successfully healed the Queen, Prince Carlos attended the crown ceremony of Mariposa and her friends.
Prince Carlos appears with his mother and Lord Gastrous when Mariposa explains her knowledge about Shimmervale. After Mariposa finish explaining the kingdom of Shimmervale, he said to his mother "See mother I told you she is the perfect choice". But Lord Gastrous interupts and claimed Mariposa haven't tell everything like butterfly and crystal fairies are enemies and how rude and mean those fairies are.
However, Mariposa proves that those fairytales are not true because they are not facts rather than myths and stated the true information of the Crystal fairies are in the history book of Butterfly and Crystal Fairies. This make Queen Marabella decide her mind and appointed Mariposa as Royal Ambassador to Shimmervale which shocked and startled Mariposa leaving the palace and decline Queen's offer.
Prince Carlos finds Mariposa in her usual spots after asking Willa. He asks why Mariposa doesn't accept the offer and Mariposa said she is not the Ambassador Material. He denies it and says Mariposa is the smartest fairy he knows and read every books on Shimmervale.
Mariposa still look downs on herself and afraid to make mistakes or make things worst to the Crystal fairies. Still he believes in Mariposa, He said she won't and that all Butterfly Fairies believe in her and gives her a tip that to make a friend is to be a friend. And he suddenly remembers something and take out a glowing crystal ball with Flutter Flower and tell Mariposa if she is in doubt, take it out and it remind her of Flutterfield.
While Mariposa in Shimmervale, he helped Willa with her library duties from Mariposa. He is first seen holding boxes of shipping books. When Willa accidently bumps into Carlos, he fell, to the floor. Willa greets good morning to Carlos which Carlos corrects her "its afternoon already" and Willa realize how late she is, she abruptly said she overslept and drop by in Flutters Bakery to buy pastries and offer Prince Carlos breakfast which he said its lunch time and Willa replies "no breakfast for you then".
Next, he is seen painting a tapestry of her mother and proudly said that two years of art school was not wasted and his mother is wrong. When Willa bring the tour people, one of them accidentally spills some smoothies into the tapestry.
After finish arranging the library books he asked Willa about reading to the elderly. Willa in return asked him the same thing. And both of them realize it is not done yet and quickly rush to the elderly but end up crashing together.
He appeared again with Willa, Mariposa, Princess Catania and Talayla. Mariposa and Catania show them how to flip their wings and all of them laugh together. Catania and Talayla leaves Mariposa and Prince Carlos alone while Willa is being chased by the tour people for refund.
Prince Carlos compliments on how amazed he is on Mariposa's good. Mariposa thanks him and said she couldn't do it without the Flutter Flower. Then a music appeared and asked Mariposa dance with him which Mariposa agreed.
- "Willa told me to find you here." (Mariposa: "Hello Carlos.") "Why won't you go to Shimmervale?" (Mariposa: "I don't think I'm ambassador material.")
- "You won't. We all believe in you. Just be yourself. And remember: The best way to make a friend is to be a friend."
- "Oh, I almost forgot. My mother asked me to give this to you." (Mariposa: "It's beautiful.") "It's a Flutter flower. It's made of the most precious magic in Flutterfield. Whenever you have doubts, just take it out and it will remind you of us."
- "You'll be welcomed at the outskirts of Shimmervale."
- "Goodbye and good luck."
- "Ah, but you're the smartest fairy I know. You read every book on Shimmervale."
Moral: "The most beautiful thing you can be is yourself." | "The best way to make a friend is to be a friend."
