Cynthia Aurora "Cindy" Vortex is Jimmy Neutron's simultaneous rival and romantic interest. While she is mostly antagonistic towards some of the characters, she can be considered, at times, to be one of the protagonists, seeing that she helps them out on their adventures many times. Cindy is voiced by Carolyn Lawrence, who also performed the voice of Sandy Cheeks from the famous SpongeBob SquarePants series.
PersonalityCindy, as said, is a bit of an antagonist, even though she's very smart and competes with Jimmy Neutronand she gets jealous of his superior intellect sometimes. She is very prideful, tomboyishly beautiful, stubborn and persistent and she was shown with these personality traits throughout the The Adventures of Jimmy Neutron: Boy Genius|series.
She is shown to be good friends with Libby Folfax, and they both harass Jimmy sometimes.
Little is known about Cindy's life before the events of Jimmy Neutron: Boy Genius, except that she has a mom and a dad.
It is known that she moved to Retroville and initially found herself the most respected and most intelligent person in her class at school, a position that she used to have. She also began a friendship with peers, such as Libby Folfax.
Jimmy Neutron took her "smartest person in Retroville" title when he moved into the house across the street from her whereupon Cindy, now second runner up, began a rivalry with him. She used to begin frequently attacks his intelligence by teasing him, playing pranks on him, and by criticizing his every mistake, even though most likely, she only does this to mask her love for Jimmy. She's frequently helped by Libby. 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" seems to suggest that she's not very happy at home.
Cindy is a member of the group of five, along with Libby, Carl Wheezer, Sheen Estevez, and Jimmy, who usually go on his adventures with him. She began developing a deep friendship with these five, despite being the most aggressive and critical person in the group.
In "Send in the Clones," the romantic clone of Jimmy went to Cindy's house to deliver some articles. Cindy (shortly) was attracted to him, but lied saying he threatened her. This is only one of many obvious indications of Cindy's budding romantic feelings towards Jimmy.
