Cindy Vortex

Cynthia Aurora "Cindy" Vortex (voiced by Carolyn Lawrence) is Jimmy's 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, as said, is a bit of an antagonist, even though she's very smart and competes with Jimmy and she gets jealous of his superior intellect sometimes. She is very prideful, stubborn, and persistent, and she was shown with these personality traits throughout the series. She is shown to be good friends with Libby, 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.

Jimmy took her "smartest person in Retroville" title when he moved into the house across the street from her whereupon Cindy, now 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, Sheen, 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.
