Libby Folfax was Sheen's female counterpart and girlfriend in Jimmy Neutron. She loves music, talking on phones, and hanging out with her best friend Cindy Vortex. In Planet Sheen she was replaced by Sheen's new crush Aseefa. It is unknown whether he is still dating Libby or not at the time of the series, since she is never mentioned or brought up. This was panned by many fans of the original series.
