She gets constantly frustrated by her henchmen, Ollie Stroy and Blou Print, and has a strong dislike (even fear) of the Marsupilami. Her base is located in Polombia in a giant bunker-like fortress. She had at least six husbands. Also she is the aunt of Pam and Julius Devort.
Felicia has blond white hair and wears a black suit with purple boots.
Felicia´s office is in the highest part of her fortress. It has got large panoramic windows. In some episodes a model of Devort City is seen in the center of the room. Her office is equipped with a large purple armchair where Felicia sits, and a smaller stool. She has got a large pink desk with control buttons and a tall light purple lamp. In the background, a large painting presumably of Devort City, hangs behind the desk.
