Nancy

''For the other character with the same first name, see Nancy. ''

Nancy François (nee, Jeffy), or just Nancy by many people, is a mentioned character in Mario The Babysitter! and Jeffy's Sister! and appears in Jeffy's Parents! as the main antagonist. She is an alcoholic and abusive prostitute who abandoned Jeffy with Mario because she hated him for unknown reasons.

1 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 who had passed away. Even though she beats up Jeffy and belittles him in front of Mario and Rosalina, Mario doesn'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.

However, over half a year later after the Jeffy's Parents incident, Nancy somehow escapes prison in search of Jeffy and possibly Feebee.

Trivia

 * While it's said that Nancy Jeffy 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 Jeffy's Dad, was the only one that cared.
 * Many fans believed that Princess Daisy was Jeffy's mom. However, this was confirmed by Logan to be fake in a stream with SML Reviewer.
 * It was revealed to be her fault Jeffy acts like a jerk towards Mario for an entire year.
 * Nancy may be pregnant.
 * We do not know what happened to her after she got arrested.
 * However in the teaser trailer for the SuperMarioLogan movie, it's revealed she escaped from prison.
 * In an Instagram post on Logan's account, we can see Pablo holding Nancy in an orange outfit, possibly a police uniform.
 * When Brooklyn T. 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 laws about M.V.T. It would be atleast 10 Years.

Reception
Throughout Jeffy's Parents, Jeffy had flashbacks showing how abusive she was to him. Thus, begins the fandom to believe she is unkind, insincere, and a liar for displaying acts of "affection" to him around Mario and Rosalina. When Nancy abused Jeffy (like restricting him for eating for a week,) this left most of the audience in anger and disgust towards her. The small minority of people who had a deep disliking for Jeffy were glad she abused him, and then gave a reason as to why he "tortures" Mario.

But, the large majority of the audience have a deep disliking towards her, and she is one of the most hated characters in the series. Unlike Jeffy, however, who most fans also hate, Nancy was specifically written to be unlikable.
