Cynthia Aurora "Cindy" Vortex is a major character in the Jimmy Neutron franchise. She is Jimmy's female counterpart and girlfriend.
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. She became best friends with Libby and Brittany 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. 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 have a bad home life. It is also hinted she may be pressured by her mother to be perfect all the time, which could be another reason she is so competitive.
Cindy is a member of Team Neutron with her best friends; Libby, Brittany, Carl, Sheen, Nick, Goddard and Jimmy, who usually go on adventures provided by the genius himself. She began developing a deep and eternal friendship with these seven, despite being the most aggressive and critical person in the group.
In her debut in "New Dog, Old Tricks", Cindy wore a pretty pink button-front, short-sleeved, knee-length dress with a frilly white collar.
In the following shorts and the film, as well as the video games, Cindy wore a pink short-sleeved button-up shirt, with black jeans, and pink shoes with a black stripe. She wore her hair in pigtails with pink ties with bangs and she had dark pink eyelids. This is still used in several promotional merchandise and clip art.
When the television series began, Cindy's entire look changed for the rest of the franchise. She now wears her hair in a single ponytail and now has grayish purple eyelids. She also now wears a green-striped halter shirt, khaki pants, and a pair of dark pink and white sneakers. Keith Alcorn said this change was to make Cindy look older as the series takes place a year after the movie.
In The N-Men, when she gained her super powers, she wore a light grey crop-top with The N Men logo on the front with dark grey seams, blue wrist bands, a red skirt with white stars, a red cape, blue futuristic boots, and a purple star on her right cheek.
She also wore a pink one-piece swimsuit in Jimmy on Ice when she was in her pool, Monster Hunt in the picture of her on a beach that accidentally came up in the lake monster slide show, Beach Party Mummy during the Egyptian beach party, and Journey to the Center of Carl when her mother was giving her acupuncture with 678 needles.
Cindy is very smart, bossy, prideful, independent, competitive, sarcastic and stubborn. Increasingly, she is forced to an authentic admission that Jimmy can indeed do some cool things and take them on very fun adventures. Throughout the course of the franchise, they start to become closer and closer as friends and start fighting less. It is also shown that Cindy secretly looks up to Jimmy, wants to be as smart as him and admires his intelligence. Sometimes, Cindy's desire to be number one can cause her to believe false flattery from the villains, so they can trick her into helping them with their evil schemes, only for her to realize the error of her ways too late.
Cindy also has a large ego and loves being the center of attention and will do anything for fame and money, even if it means constantly annoying people by reminding how talented and beautiful she is.
Libby and Brittany are Cindy's best friends and the only characters that she has shown no anger or aggression towards in the franchise. Their friendship is very strong and they are clearly very close. Libby and Brittany are also the only characters that Cindy has been seen frequently confiding in.
Even though Cindy teases Jimmy, she does care about him and doesn't like it when Jimmy is sad and always tries to comfort him. Some perfect examples would be in the movie when she goes to comfort Jimmy when he starts crying and in Billion Dollar Boy, when she finds out that Eustace was just using her to hurt Jimmy and then have Jimmy watch Goddard die. It is also shown that Cindy wouldn't physically abuse Jimmy, although she does hit him sometimes.
While Cindy constantly makes fun of Jimmy's alleged nerdiness, she is a genius like him and loves science just as much as he does, her genius IQ just isn't as big as his. Also, while her condescending demeanor would suggest otherwise, she isn't any more popular with other kids than Jimmy is, and she has no close friends aside from Libby and Brittany.
In Stranded, it is revealed that she actually can be more open about herself when she's away from pressure, friends and competition, and that she also may hold some bitterness toward her mother from pushing her so hard all the time and from her father not being around all the time.
In the (non-canon) Jimmy Timmy Power Hour trilogy, she is shown to have an unrealistic side, as she easily believed everything Timmy said, even though he was clearly lying and let Jimmy and Timmy fight over her, even though it was causing a lot of trouble. Later, Cindy began to realize that Timmy is not a genius, but she still liked him because she knew he really did care about her. However, it is implied she was just trying to make Jimmy jealous.
Main Article: Jimmy and Cindy's relationship
In the franchise, Jimmy is Cindy's male counterpart, former rival, love interest and eventual boyfriend. Since they are both geniuses, they have a strong competitive rivalry and they act as if they dislike each other in front of peers to hide that they are crushing on each other. Despite this, Cindy does care about Jimmy and doesn't like it when Jimmy is sad and often tries to comfort him. Jimmy still sees Cindy as a friend because she's the one person who can keep him on his feet. As a result, their chemistry is a bit inconsistent.
Towards the end of the series, Cindy begins to flirt with Jimmy, and often is angry when he likes other girls, ignores her, takes credit for her ideas or blames her for his actions. In the third season, they get along when they are alone and pretend to argue only when others are around.
In Lady Sings the News, they are revealed to have been dating secretly for a portion of the third season. In the next episode, Cindy finally openly reveals her feelings for Jimmy (sort of).
In the planned season four, Jimmy and Cindy would've finally ended their fighting once and for all, since they would become an official couple before the series' ended.
In the second crossover special, Cindy and Jimmy were planning to go to the dance together but Timmy's untimely arrival ruined it. Soon, Jimmy and Timmy started fighting over Cindy, which she allowed because she was happy to be getting attention, despite the trouble it was causing.
In the third crossover, after learning that Cindy is on a family vacation, Jimmy and Timmy become fast friends and ignore Cindy when she returns. Her crush on Timmy ended once and for all when he called her 'Debby' when she entered Jimmy's lab and when Timmy was the one to boot her out.
While Cindy's feelings for Timmy are more open than her feelings for Jimmy, it's more of a crush than actual love or a relationship, and the fact that during the last Power Hour Cindy is already Jimmy's girlfriend and Timmy has pretty much forgotten about Cindy at this point and vice versa. Not to mention that in Timmy's future, he is married to Tootie.
Cindy had a crush on Nick in the movie and a portion of the first season and often tried to get his attention, only to constantly be sabotaged by Jimmy and his pranks. Her crush on Nick ended once and for all after Jimmy embarrassed Cindy in front of Nick in Trading Faces. Cindy and Nick do remain friends after this, however. They share fairly good chemistry.
Libby is Cindy's best friend. Libby also shows a deep understanding of Cindy's actions and feelings, and can tell when Cindy is lying. Libby also knows that Cindy has a crush on Jimmy and wants her to tell him how she feels. It is also shown that Cindy is aware that Libby likes Sheen. This says very much about the strength of their friendship, as Cindy is very guarded about her feelings, and doesn't allow many people to become close to her. Cindy likes Libby because she is loyal and a true friend to her. The two share good chemistry.
Brittany is Cindy's other best friend. Even though Cindy and Brittany don't hang out as much as Cindy and Libby do, they get along well and are good friends. Cindy likes Brittany because she's ditzy, off-the-wall and the one person in their friend group who can make her feel smart, which Brittany doesn't notice and is usually confused by. Even though Cindy and Libby usually pick on Brittany, they still love her and the three of them are close. The three of them share good chemistry.
Carl Wheezer and Sheen Estevez
Cindy hates Carl and Sheen because they're weird and they hate her because she's mean. Despite this, the three are part of Jimmy's team, since he is best friends with Carl and Sheen and Cindy likes Jimmy. The three share bad chemistry.
Little is known about Cindy's family life, which makes it somewhat questionable. Her dad is hardly ever seen on screen, having no speaking lines, and only appears in the movie and in "Make Room for Daddy-O". Her mom is pushy and prideful of her daughter. Some of Cindy's statements in Out Darn Spotlight, Maximum Hugh and Stranded hint that she might have a tough home life and a bad relationship with one or both of her parents. However, the movie and moments in certain episodes show that they do care for Cindy.
Humphrey is Cindy's pet bulldog and one of the few people she shows love and affection to.
Cindy only disliked Betty throughout the franchise because Jimmy had a crush on her. Betty often flirted back to Jimmy, which always upsets Cindy, and she sometimes lashes out at them in jealousy over it. She has very little actual interaction with Betty; most of what we know of her thoughts on Betty is from when Cindy expresses jealousy of her. We eventually learn that Betty doesn't hate Cindy because she likes Jimmy, but because she's always mean to her.
In the episode Vanishing Act, Betty shows that she is aware of Jimmy and Cindy's feelings for each other and seems to even be supportive of the two getting together, but it's hard to show it because Cindy is always mean to her. She no longer flirts with Jimmy after this point in the series and is reduced to a supporting character. Jimmy and Betty still remain friends, however. Also, Cindy and Betty start to get along for the rest of the series.
In the series finale, Cindy displays what could be a slight attraction to Betty when looking at a picture of her in Jimmy's lab; instead of being immediately upset that Jimmy had the picture, she smiled and giggled at it until Carl took it from her. Until that point she had shown nothing but resentment towards Betty, so this scene hints that Cindy may be secretly fond of Betty. In addition, it is shown that she thinks Betty is hot, as well as "beautiful and perfect".
In the planned season four, there would have been an episode called "Three's a Crowd", in which Cindy, Libby, and Betty got trapped in Jimmy's lab and have to work together to get out. In said episode, Cindy would have finally opened up to Betty and the two would've become friends.
Cindy briefly disliked April because of her and Jimmy's slight interest in each other, and when she catches April kissing Jimmy, which in Gorlock culture was a symbol of trust, she misinterprets it as Jimmy and April being affectionate, yelling at them, only then to claim that she doesn't care. April senses her jealousy and then assumes she is Jimmy's mate (to which both Jimmy and Cindy react with gagging and profuse denial). When the characters team up to stop Meldar, April and Cindy become a tag team and defeat Meldar's robots together. At the end of the special, right as 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. When April is flirtatious towards Jimmy in the message, Cindy gets mad at him, then Jimmy attempts to respond to her message and Cindy cuts it short, so Jimmy won't endanger the planet again.

- Her name was originally going to be Sally Proton and her hair was going to be black.
- Cindy is the only main character from the franchise not to have a Planet Sheen counterpart.
- Cindy has had the most outfit changes out of all the characters.
- Cindy was called by her full name "Cynthia Aurora Vortex" by Carl in the episode: The Incredible Shrinking Town when he imitated Sasha's voice.
- Coincidentally, Carolyn Lawrence is also known for voicing Sandy Cheeks in the SpongeBob SquarePants franchise.
- Her blood type is A+, as mentioned in "Nightmare in Retroville".
- According to a 2005 Nickelodeon equinox card, she was born on June 5th in Las Vegas, Nevada.
- Since Cindy doesn't have any resemblance or physical features her parents have, there is a fan theory that she is adopted. Jimmy actually pointed out the likelihood of this possibility in the show, observing that she doesn't have the same hair or eye color as her parents. However, Cindy and her mother have green eyes or that could be a coincidence.
- Cindy's birthday being June 5th means she's a Gemini.
- In the franchise, she has green eyes, but in the Fairly OddParents universe, she has blue eyes, possibly due to the stereotype of blonde haired people having blue eyes.
- Her design in the film bears a physical resemblance to Dorothy Ann from Scholastic's the Magic School Bus.
