Riki is the prince of Arendelle. He turned into a beast. I'll tell you why. One day, a goddess of beauty and charity visited his castle while they were having a party as she knocked she was diguesed as a old woman "Please.. Have this rose." She said as Riki scoffed taking the rose "This ugly thing?" Riki looked digusted as he threw the rose of the floor stepping on it making her angry as she turned into her normal self "You shall perish!" That's it he turned into a beast.
