Liberty Danielle "Libby" Folfax is one of the main characters in The Adventures of Jimmy Neutron: Boy Genius. She is a sassy African American girl first appearing in the Jimmy Neutron: Boy Genius film. She is Cindy's best friend and Sheen's love interest.
Libby's main interest is music with the funky rhythm. When she experiences music withdrawal, she faints (as revealed in "Hall Monster").
She also loves electronic gadgets and being stylish. In the first
season, she doesn't appear in the title logo. When she becomes more
involved in the show, however, she is added to the logo in the second
season and is still on it in the third season. Unlike Jimmy's best
friends, Libby is shown to do well in school, but isn't at the level of Jimmy or Cindy in terms of intellect.
