Mônica Sousa was born in
Bauru, daughter of designer and entrepreneur Mauricio de Sousa and Marilene Spada. She is the second daughter of the couple, who were also parents of Mariângela, Magali and Mauricio Spada, who died in 2016. In 1963, when she was two and a half years old, her father created the character for
Folha de S. Paulo, inspired by some traits of personality and the daughter's appearance: slightly toothy, short, fat and quarrelsome, besides carrying a stuffed rabbit, but of yellow color. The idea of creating a female character came after a journalist colleague of Mauricio said that the creator was
misogynist, because he created only male characters. Monica would discover herself to be the inspiration of the character at the age of 7 or 8, after a schoolmate told her that she was the character of the comic strips of Folha, which made her curious, and had her doubt confirmed by her father, but her acceptance was quick. ==Career==
