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. But he is able to prove it right when Willia 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.
