Mrs. Megamounds was born Maxine Milkymams, a woman inheriting her family's strange genetic anomaly which causes their breasts to grow comically large and constantly produce milk. Maxine used her unique mutation to catch the eye of billionaire mineral magnate Morty Megamounds, and they were married shortly before his untimely passing at the tender young age of one-hundred and three. Unfortunately, a secret will bequeathed his fortune to Morty's family, and Maxine was left penniless, forced to take a job as the manager of the MnF Metropolis Mall. Because of her previous life of luxury as the wife of a billionaire, Mrs. Megamounds is a stuck-up, entitled bitch who needs to continuously be put in her place by being reminded of the fact that she's only good for one thing - milking and fucking!
