Felicia has a warm, caring personality, especially towards the Avatar. She is steadfastly loyal to them and readily follows them without a moment's hesitation, even fighting against her own tribesmen, her older sister Flora, and her father, Kilma. While typically sweet, she can get feisty if she feels like she is being talked down to, particularly in her supports with Subaki, Saizo, and Takumi. Felicia is very clumsy and prone to making mistakes when performing her chores, much to her own embarrassment. Despite this, she strives to become a proper maid, like her sister Flora.
