Her personality was greatly inspired by actress Barbara Stanwyck, specifically her roles in 1940s comedies such as The Lady Eve and Ball of Fire. The Disney iteration loosely took from this by casting Megara as Hercules' love interest, the Lois Lane to Hercules' Superman. Megara is a character that originates from Greek mythology, the wife of Heracles. According to a brief exchange, however, Hades held some amount of sympathy for Meg's plight and was open to subtracting years from her sentence based on her performances in the field. Having become jaded and cynical as a result of her past, Meg upheld her end of the bargain by assisting Hades in his quest to take over the cosmos. Since then, she's had trouble trusting others and finding the courage to love again.

Her boyfriend was revived, as agreed, but he heartlessly left Meg for another woman shortly thereafter. To save him, she sold her soul and offered servitude to Hades, God of the Underworld. She deeply cherished the relationship she shared with her boyfriend, who one day lost his life.

In her youth, Meg was romantic and open to giving love.
