Libby Folbax

Liberty Danielle Folfax (or better known as Libby) is one of the main characters from The Adventures of Jimmy Neutron, Boy Genius. She is Cindy's best friend and Sheen's girlfriend.
Libby is smart and sophisticated, is a dancer, loves music, electronic gadgets and is a math genius. When Cindy goes too far, Libby gets them quickly back to the Earth. Libby is very loose on it and sings for her life. She also has more common sense, is more down-to-earth than her friends and is the voice of reason. Libby also serves as a big sister to Jimmy and often tries to help him come out of his shell. Libby also is a very honest person and literally cannot lie, which makes it hard for her to keep secrets or be involved in Jimmy's plans.
