Cynthia Aurora "Cindy" Vortex is Jimmy's former arch-rival and current girlfriend.
Cindy is basically the hero-cute blonde role. She is very smart, beautiful and cute, kind, prideful, independent, tomboyish, persistent, competitive, and somehow stubborn. She sometimes competes with Jimmy. She was shown with these personality traits throughout the series.
Cindy's best friend is Libby, and she is shown to be good friends with her.
While she has a crush on Jimmy, she pretends to dislike him to hide her true feelings. Although she has also once kissed him.
In Crouching Jimmy, Hidden Sheen, Cindy asked Jimmy to a dance show, but Jimmy was more concerned about Yoo-Yee and his ninjas.
In the Jimmy Timmy Power Hour trilogy, Cindy has a relationship with Timmy Turner.
Little is known about Cindy's life and past 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 second runner up, began a rivalry with him. She used to begin frequently attacks his intelligence 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.
In the shorts and film, Cindy wore a pink short-sleeved button-up shirt with black jeans and pink sneakers. She also wore pigtails with her trademark bang. In the short "New Dog, Old Tricks", she wore a pretty pink button-front, short-sleeved, knee-length dress with a frilly white collar.
When the television series began, Cindy's entire look changed: She began wearing a single ponytail in her hair, as well as changing her entire wardrobe. She now wears a green-striped halter shirt with khaki pants and a pair pink and white Converse All-Stars. She also wears polka-dotted panties, as shown in "When Pants Attack".
Cindy has indeed shown obvious, but reluctant friendship with Jimmy, whom she calls numerous nicknames, the most common of which being "Nerdtron". In the episode Stranded, Jimmy was shocked when she called him by his real name, believing she never knew it.In the first season, she "crushes" on Nick Dean. In the second season, nicknamed "The Relationship Season", their relationship begins to show through much more. Throughout the second season, the viewer observes a blossoming albeit odd romance between Jimmy and Cindy. Their relationship finally becomes acknowledged by Jimmy and Cindy in the middle of the third season, when they equivocally admit their true feelings while stranded on an uncharted island in "Stranded". In Crouching Jimmy, Hidden Sheen, Cindy asked Jimmy to a dance show, but Jimmy was more concerned about Yoo-Yee and his ninjas. During The League of Villains, Cindy makes several attempts to confess her love to Jimmy, only to be inadvertently interrupted by someone or something and ignored by Jimmy. It is also hinted that Jimmy has feelings for Cindy in "Billion Dollar Boy" when he agrees to accompany Eustace after Cindy shows that she kind of likes Eustace. Later, however, that interest turns to dislike after Eustace says that he has no further use for "Neutron's squeeze". Season three is rich with what Jimmy and Cindy fans call "J / C moments". In "My Big Fat Spy Wedding", she saw Jimmy in a tux and got hearts in her eyes while her jaw dropped calling him a 'hunk muffin'.
Cindy also knows when things are going too far. Increasingly, she is forced to an authentic admission that Jimmy can indeed do some cool things and have cool adventures. During season three, as she starts to come to terms with her feelings for Jimmy, she mellows out, slowly dropping their rivalry and picking on Jimmy and his friends less and less. Instead, she begins to make several attempts to get Jimmy's attention.
By the end of League Of Villains, Jimmy and Cindy start dating, and in Lady Sings The News Jimmy and Cindy finally kiss.
- In the movie, when flying the rockets, they briefly stare at each other.
- In Beach Party Mummy, Jimmy carries Cindy on his back, and they also dance together.
- During "The Retroville 9", they briefly share a victory hug.
- In "My Big Fat Spy Wedding", Cindy catches the bouquet, looks at Jimmy, he looks back, and they share a short moment before she throws the bouquet to someone else.
- At the end of "I Dream of Jimmy", Jimmy kisses dream Cindy in order to get Carl to realize it was a dream, however he said it was "a horrible and desperate thing [he] had to do". At the end however Cindy storms in and slaps him meaning she probably dreamed of Jimmy kissing her.
- In "Return of the Nanobots", when everyone reappears, Jimmy catches Cindy, since she appeared in the sky. They look at each other and smile before he drops her.
- During "Stranded", they inadvertently reveal their feelings for each other, and almost kiss. Jimmy gives Cindy an oyster containing a beautiful pearl. They also hold hands.
- In "The N-Men", Cindy tries to tell Jimmy her feelings but faints before she gets a chance to.
- In The League of Villains, Cindy constantly tries to tell Jimmy her feelings only to be interrupted each time. Jimmy kisses Cindy on the cheek and they start dating at the end.
- In "Lady Sings the News", they are shown to be dating as they interact romantically several times, specifically at the end when Jimmy kisses her and their new relationship is left to the imagination of the viewers.
- In "Trading Faces", Cindy stated that one of them imagined them holding hands while walking down a country meadow and kissing.
- In "King of Mars", Cindy tries to flirt with Jimmy but got angry when he kept on ignoring her (later revealed he was doing so because her beauty kept distracting him).
- In "Win, Lose and Kaboom", Cindy and Jimmy almost kiss, with Cindy nervously asking him how the Gorlockan Seal of Trust worked.
- In "Party at Neutron's", Cindy sees Jimmy and Betty dancing and a sad expression appear upon her face. She then talks about how "she would never dance with Jimmy if he was the last kid on Earth".
- In "Lights! Camera! Danger!!" Cindy and Jimmy almost Kissed in one scene on a Roller coaster In Retroland, but They stopped when Jimmy realized that the tracks were broken.
- In "Crouching Jimmy Hidden Sheen", Cindy wanted to enter the school dance show with Jimmy but was sad when she heard him saying it was lame to Carl and Sheen, then at the last minute Jimmy easily accepts before she asks fully.
In "Jimmy Timmy Power Hour" trilogy which is not canon, Cindy develops a small crush on Timmy who everyone else thinks is Jimmy with a smaller head. In the second crossover special, Cindy and Jimmy were planning to go to the dance together but Timmy's untimely arrival complicates things. However, her feelings for Timmy, while more open, definitely aren't as strong as her love for Jimmy. In the third crossover, after learning that Cindy is on a family vacation, Jimmy and Timmy become fast friends and ignoring Cindy when she returns. Her crush on Timmy vanished when he called her 'Debby' when she entered Jimmy's lab and when Timmy was the one to boot her out.
In "Send in the Clones", the romantic clone of Jimmy went to Cindy's house to deliver some articles. Cindy (shortly) was attracted to and flattered by him, but lied saying he threatened her. This is only one of many obvious indications of Cindy's budding romantic feelings towards Jimmy.
Libby is Cindy's best friend, and one of the few characters that she has shown little to no anger or aggression towards during the series. Their friendship began before the movie or the series, as they are clearly very close even during the movie. Libby is also the only character that Cindy has been seen frequently confiding in.
Libby also shows a deep understanding of Cindy's actions and feelings, shown on multiple occasions. Libby also knows that Cindy has a crush on Jimmy. This says very much about the strength of their friendship, as Cindy is a very guarded and argumentative person, who obviously doesn't enjoy allowing many people to become close to her.
Carl Wheezer and Sheen Estevez
Cindy's "friendship" with Carl and Sheen is obviously strained. She is shown to be annoyed by both of them, while they think that she is violent and mean.
Despite their dislike for each other, the three are drawn together by Jimmy, who befriends Carl and Sheen, and eventually Cindy, and Libby, who is friends with Jimmy, Sheen, Cindy and Carl. The group is formed because of this, and the five become friends, including Cindy, Carl, and Sheen which they go on unexpected adventures that make up the series.
Little is known about Cindy's family life, which is what makes it so questionable. Her dad is hardly ever seen on screen having little or no speaking lines and only appears in "Make Room for Daddy-O", while her mom seems to be pushy and prideful. Some of Cindy's statements in "Stranded" also bring her happiness at home into question.
She's primarily disliked her because Jimmy has fallen head over heels for her. In the episode "Vanishing Act", Betty pulls Cindy aside to confront her about the Cindy/Jimmy thing. Cindy instantly questions what she is talking about, nervously repeating herself and denying that anything is going on between the two of them. Betty merely chuckles at this and tells Cindy to stay out of her face and that Jimmy is "all yours". Cindy visibly smiles and squeals the word "Yes!".
April the Gorlock
Cindy is shown to dislike April because of Jimmy's affections for her. After she catches April kissing Jimmy, which in Gorlock culture was a symbol of trust. She misinterprets it as Jimmy swapping "alien spit" with April, only then to claim that she doesn't care at all. April then assumes she is Jimmy's mate, causing both Jimmy and Cindy to gag at the statement. At the end of the special, just when Jimmy and Cindy are about to kiss, a space rock hurtles down from the sky to land just outside of the Candy Bar. Both race outside to find that it is a message from April.
Cindy only shows anger at Yoo-Yee when he triple-axle-midair-betsy flips him in the head, finishing him!

It is also possible that she went to Jimmy's Lab, found out what Yoo-Yee did and decided to go rescue her best friend when she saw the videodisc's contents.
