He is 10 years old in the first season, 11 in the second season, and 12 in the third and final season. He is the son of Judy and Hugh Neutron. His best friends are Sheen Estevez, Carl Wheezer, and his robot dog Goddard. He and Cindy Vortex have a dislike for each other, although it is revealed in later episodes that they secretly like each other. Jimmy is usually seen wearing a red T - shirt with his yellow trademark atom symbol on it, blue jeans, and white Chuck - Taylor Converse All - Star sneakers, but blue shorts and brown shoes in the film. He has blue eyes and huge brown hair that is considered `` anti-gravity '' and is in a whipped - up form, earning him many nicknames from classmates ( especially Cindy ), such as `` Whippy - Dip '' from his clone Evil Jimmy, and `` Señor Fudge - Head '' and `` Buzz Adams '' ( from Cosmo in The Jimmy Timmy Power Hour ). In addition to his parents, several of his other relatives have also appeared on the show. Sheen Estevez Voiced by : Jeffrey Garcia Sheen Estevez is Jimmy 's slightly older, hyperactive, addled best friend, characterized by his unhealthy obsession with the fictional superhero `` UltraLord '' and the television series, video games, and merchandising inspired by the character. Sheen, who wears an UltraLord T - shirt, has amassed a collection of UltraLord memorabilia and also created a website dedicated to the superhero. Sheen lives with his father and grandmother. Sheen 's father makes a brief appearance in season one, although his face is not shown. Sheen is noted for his extreme, constant bouts of hyperactivity, which he demonstrates multiple times per episode, along with his misdirected intelligence and short attention span, to the annoyance of his peers. Alongside UltraLord, Sheen also appears to be interested in superheroes in general and in typical masculine subjects such as wrestling, and is strongly infatuated with Libby Folfax, becoming her boyfriend by the time of the program 's conclusion. Sheen would later star in his own spin - off show, Planet Sheen, which premiered in 2010. In this series, he goes into Jimmy 's lab and steals his new rocket ship, which crash lands on the planet Zeenu. Due to the series being short - lived, he is never shown returning to Earth. However, in `` The Tomorrow Boys '', a 2005 episode of The Adventures of Jimmy Neutron : Boy Genius that involves time travel, Sheen is shown to be living on Earth in the future. Sheen 's full name is a pun on the last names of both stage name and real names of father - son actors Martin Sheen, Charlie Sheen, and Emilio Estevez. Carl Wheezer Voiced by : Rob Paulsen, Wally Wingert ( 2002 PS2 game only ) Carl Wheezer is a bespectacled dim - witted boy and one of Jimmy 's best friends. Carl and his parents have numerous allergies, at times even to things that are incapable of triggering allergic reactions. He passionately loves llamas, and his passion for them is often used as a running gag throughout the series. He is also a bit cowardly and developed a crush on Jimmy 's mom. An extraterrestrial character named Doppy, with similarities to Carl, is a main character in Planet Sheen. His extreme obsession for the llama originated when his parents expanded their cable lineup and he became devoted to a show called Llama Boy The Super Hero. Since his obsession began he has gone to great lengths to express his love for them, going as far as to join a fan club called, The Llama Love Society. Cindy Vortex Voiced by : Carolyn Lawrence Cindy is a blonde - haired girl with green eyes, wears a fading - green shirt with stripes and wears her hair in a pony tail with her trademark bangs. In her debut, she wore a pink shirt with black jeans and pink sneakers and wore her hair in pigtails. She is very good at tai - chi. Her close friend is Libby. She has a dog named Humphrey, who is seen in many episodes, usually accompanying her. She is Jimmy Neutron 's rival but in the 2006 episode, `` Lady Sings the News '', Jimmy and Cindy officially start dating, which was predicted in earlier episodes like `` Win Lose and Kaboom ! ''. In `` The Tomorrow Boys '', Jimmy, Sheen, and Carl traveled to the future, where future Jimmy revealed he and Cindy were married. It is unclear whether this is the true future since the gang changed the past by the end of the episode. In The Jimmy Timmy Power Hour trilogy, Cindy has a relationship with Timmy Turner. Cindy 's mother, who was born in France and loves French food, has high standards for Cindy and expects her to follow in her footsteps. Her mother is an accountant. Cindy 's father makes an appearance in the episode `` Make Room for Daddy - O. '' Libby Folfax Voiced by : Crystal Scales Libby Folfax is Cindy 's sassy, wealthy close friend for whom Sheen has been shown to possess an infatuation. She is African American and has black hair that is always styled accordingly. Early in the series, Libby dislikes Jimmy and his friends and often sides with Cindy, but as the series continued, both Libby and Cindy become more attached to Jimmy, Carl, and Sheen. Libby later became Sheen 's girlfriend, much to his glee. In one episode, Libby mentions that her ancestor was the fictional Queen Hasabataslapya ( `` how 's about I slap ya ? '' ) of Egypt, who died at a young age. During the episode, Libby was forced to masquerade as the queen in order to distract a group of revived mummies ( as the ancient portrait of the queen strongly resembles Libby ). For the rest of the series, Libby kept her new hairstyle, and her wardrobe also changed. She adores popular music and dancing, and lusts for it as soon as it has been taken away from her for any reason. Libby 's father appears in the episodes `` Make Room For Daddy - O '', `` Men At Work '', and `` Win Lose and Kaboom ''. He has also made cameo appearances in several episodes. Libby 's mother ( also voiced by Scales ) appears in `` Journey to the Center of Carl '' and `` The N - Men ''. Goddard Voiced by : Frank Welker Goddard is Jimmy Neutron 's robotic dog that Jimmy invented himself. He was named after the famous American engineer, Robert H. Goddard. Hugh Neutron Voiced by : Mark DeCarlo Jimmy Neutron 's father, Hugh Neutron is portrayed as a clueless, dimwitted, but good - natured, and fatherly person who frequently offers advice to Jimmy. Ducks are Hugh 's favorite hobby ; he enjoys collecting figurines of ducks and displaying them around the house. Hugh also loves the pies that are baked by his wife Judy. In one episode, Hugh invented a holiday called `` Pule '' ( a combination of Pie and Yule ) when Jimmy accidentally causes Christmas to be replaced by messing with Santa 's atoms. Judy Neutron Voiced by : Megan Cavanagh Judy Neutron, Jimmy 's mother and Hugh 's wife, is a housewife. She has auburn hair in a 1950s style hairdo and green eyes.

Bolbi stroganovsky Voiced by Phil LaMarr Also known as the `` boy from fairy - tale land '' or the `` boy with the funny name '', Bolbi is the strange resident exchange student from Backhairistan. He normally speaks broken English, but is shown to have a surprisingly good Shakespearean acting voice when auditioning for a play. He dresses in stereotypical Eastern European garb and has an accent of indeterminate origin, and joins Jimmy, Carl, Sheen, Cindy, and Libby to the game show in `` Win, Lose, and Kaboom ! '' He states that `` Super-Kabobby Man '' is the most famous hero of Backhairistan. It is known that he has a blond sister who looks just like him in `` Crouching Jimmy, Hidden Sheen. '' He has a musical pet goat named Yurri. Miss winfred Fowl Voiced by Andrea Martin The teacher for Jimmy and his friends, who frequently squawks like a chicken when speaking.

Nick is obsessed with styling his hair, and is considered very handsome by all girls in the school. He is of Brazilian American descent, and his mother speaks Portuguese and English. Nick sometimes breaks his leg while riding his skateboard ; when he does so, he usually lets out a high pitched girl - like scream.

He is one of the towns ' wealthiest children, living in a 92 - room mansion, with a bowling alley, maids ' quarters, a screening room, and a soda parlor. He can also sing operatic German, and can style his hair without using his hands. In the movie, he was almost always seen with a purple lollipop in his mouth. He is very strong ; in one episode, he was able to beat up Jimmy, Carl, and Sheen and throw them all into a dumpster. However, he can be a coward at times and even a wimp as in the movie when he confronted Poultra, he ran away screaming like a girl. He wore a sleeves jacket for the first half of the series then switched to a leather jacket. Principal willoughby Voiced by Rob Paulsen The flamboyant, Broadway - loving Principal at Lindbergh Elementary School. He is also somewhat overweight.

Professor Finbarr Calamitous was once a brilliant boy who could never finish anything, not even a sentence. The only thing he could finish was a robotic suit, although he did not consider it finished since he did not put a bathroom into it. He later overcomes this to some extent, and Finbarr Calamitous is heard completing sentences as seen in `` Operation : Rescue Jet Fusion '', `` The Great Egg Heist '', and `` The Jimmy Timmy Power Hour 2 : When Nerds Collide ''. However, he still has a habit of not finishing his plans, or more specifically, he is able to carry out his plans but does not plan on what he is going to do after that.

Sheen 's terrible singing voice, however, lulls them to sleep. The Twonkies can combine themselves into a large eight - foot tall seemingly invincible monster that can only be subdued by Sheen 's bad singing. Jimmy manages to capture most of the Twonkies, and sends the merged beast back to its comet ; but he forgets Sheen 's, which escapes and reproduces asexually.
