Cindy Vortex

Cynthia Aurora Vortex is a major character in the Jimmy Neutron franchise. She is the female counterpart, arch-rival and girlfriend of Jimmy Neutron.
== Background ==
Before Cindy moved to Retroville, she initially found herself the most respected and most intelligent person in her class at her old school, a position that she used to have until she moved and met Jimmy Neutron. She became best friends with Libby Folfax and Britney Tenelli after moving.
Jimmy took her smartest person in town title when she moved into the house across the street from him, whereupon Cindy, now second runner up, began a rivalry with him. She started to begin to frequently attack his intelligence by criticizing his every mistake, even though she only does this to mask her love for Jimmy and to cover up her insecurities and her fear of failure. Despite Jimmy's superior intellect, she often manages to outsmart or upstage Jimmy due to his own impulsiveness or clumsiness. Her home life is rarely shown, and her parents are only minor characters in the show. But some of the statements she makes during Stranded seem to suggest that she may be pressured by her mother to be perfect all the time, which could be another reason she is so competitive and mean all the time. However, her parents are seen doting on her near the end of the official movie, so it's entirely possible that they love her, but aren't sure of the right ways of showing it.
Cindy is a member of Team Neutron with her best friends; Libby, Carl Wheezer, Sheen Estevez, Nick Dean, Goddard and Jimmy who usually go by the genius himself. She began developing a deep and eternal friendship with these six, despite being the most aggressive, snarky and critical person in the group.
