Nancy is the biological mother of Jeffy. She was a mentioned character in Mario The Babysitter! and Jeffy's Sister! and finally debuts in Jeffy's Parents! as the main antagonist. She is an alcoholic and abusive prostitute who abandoned her son with Mario because she hated him for obvious and unknown reasons.


One year later, during the events of Jeffy's Parents!, Nancy comes to Mario's house to get Jeffy back after finding out that Jeffy was to inherit millions of dollars from his father, Jacques Pierre François, who had committed suicide for the sake of his artwork. Even though she beat up Jeffy and belittles him in front of Mario and Rosalina, Mario didn't care, while Rosalina is concerned. In the car, she starts beating Jeffy senseless, until he escapes and goes back to Mario's house, begging Mario to let him stay with him and the gang. He also genuinely promises to stop annoying Mario and disobeying him (which he eventually breaks). Then, Mario calls the police on her, and she gets arrested for child abuse, prostitution, and "a bunch of other things". Mario then decides to adopt Jeffy and let him stay, as long as he behaves. But Mario probably lets him stay because he secretly loves Jeffy.

  • It is possible that her full name is either Nancy Jeffy or Nancy François.
  • While it's said that Nancy and Jacques Pierre François hated Jeffy, the note may actually mean that they care about their son and Jeffy may have been kidnapped. This probably wouldn't have happened if they hated Jeffy, however, it's revealed that Jeffy's mom didn't care, so it's possible that Jeffy's Dad was the only one who cared.
  • When Does Bad Things Guy states that Nancy is arrested for "a bunch of other things", it is assumed that Nancy is charged with: Motor Vehicle Theft, Prostitution, Child Abuse, Child Neglect, And Child Abandonment. Her prison sentence is unknown, but due to Florida's laws about M.V.T, it'll be at least 10 years or so.
  • Although she despises Jeffy for being idiotic and called him "ugly" and "stupid", it was actually her own fault that she never takes care of him and has no responsibility.
  • She will return in The SuperMarioLogan Movie! as the main antagonist, going after Jeffy's money and presumably assembling other past antagonists for this purpose.

    • So it'd also be similar to Crayon Shin Chan's game for the GameBoy, and quite a few other platformers.
    • great idea
  • How is she any different from Bowser?

    • Bowser usually beat Junior not just for laughs but also since it was warranted given Junior would act like a dick in the episode.  Nancy b...
    • It still does not seem to make a difference. Plus most of the time Bowser does beat junior for “existing”
