Jimmy Neutron is the main protagonist of the series is a super intelligent boy who always uses science to solve issues (even though he causes most of them). He is the son of Hugh & Judy Neutron. He is best friends with Sheen Estevez & Carl Wheezer who happens to be his test subjects for his experiments & inventions. At the beginning of the series Cindy Vortex is his enemy but he secretly has feelings for her (and vice versa). For example, in "Love Potion 976/J" he is exposed to a love potion in which he created. He would be attracted to the first girl he saw which in this case was Cindy. Later in the episode he proclaims his love for her at the "Candy Bar".
Goddard Jimmy's trusty robotic dog. He is made of sprockets, circuits and widgets, and makes a great man's best friend.
Carl Wheezer Jimmy's shy, asthmatic right hand man. Carl is allergic to lots of things, including cats, turtles and even lasers. Yet he still helps Jimmy with his experiments. In the movie, Carl wore suspenders but in the TV show he doesn't. In a few episodes it is shown that Carl has a crush on Jimmy's mom. Although Carl didn't make a in-person appearance on Planet Sheen, he appears in one of Sheen's flashbacks. Carl also has a massive obsession over Llamas. While often dismissed by the group of friends, Carl often saves the day and utters occasional pearls of wisdom which belie his station as resident nebish: "The heart wants what the heart wants" "I can not be a genius 24/7!" and "I don't want to be cool." It is also said he has an sensitive scapula.
Cindy Vortex Jimmy's sassy, 11 year old independent, intellectual rival. She has a dog named "Humphrey" who she says is the best dog in Retroville. Her best friend is Libby Folfax. In the movie Cindy in seen wearing a pink buttoned shirt, black jeans, pink shoes, and her hair styled in pigtails. This design of Cindy was used more often for Jimmy Neutron videogames. Also in the mini clip of Jimmy Neutron entitled 'New Dog; Old Tricks, Cindy wears a pink skirt. But in the TV show her hair is styled into a ponytail with a green halter top, khaki pants, and pink converse shoes. She has a secret crush on Jimmy, the show gives little hints of it throughout the seasons, but doesn't actually show it until Season 3. Although not confirmed, it is possible she might appear in Planet sheen.
Sheen Estevez Voiced by: Jeffrey Garcia. Sheen Juarerra Estevez is Jimmy's other best friend, a hyperactive 13 year-old boy who is known for his obsession with a fictional superhero called "Ultra Lord" who stars in a television program that Sheen frequently watches (perhaps unsurprisingly, Sheen wrote the entire "Ultra Lord" website on the Internet). Sheen is also a fan of Speed Metal. At times Sheen's hyperactive personality boils over, often causing him to scare Carl. He is also best friends with Carl. In Operation: Rescue Jet Fusion (a spoof of James Bond) Sheen states that he is Mexican. Sheen's name is a parody of the Estevez-Sheen family of actors consisting of many famous actors such as Martin Sheen and his sons Emilio, Ramon, Carlos (a.k.a. Charlie Sheen) and Renee. Besides having a loud voice, Sheen is older than most of his classmates, but it's not because Sheen was held back a year, but because his father made him start kindergarten a year late because he was shy as a young child. Sheen's mother was mentioned but has never appeared in the series before. Sheen also has an unseen younger sister, but she was only mentioned in "I Dream Of Jimmy" when she argued with Sheen about the possible existence of the "Potty Fairy." Sheen also has an ongoing crush on Libby Folfax, and at the beginning of the series she constantly taunted and rejected Sheen just how Cindy was with Jimmy before their romance blossomed. Towards the end of the series, however, Libby agreed to be Sheen's girlfriend, which gave him the strength to fight an enemy in one episode. Of all the characters on "Jimmy Neutron", Sheen acts the oddest. In one episode he is the only person who continually ate the literally-shocking candy that Jimmy invented and in two others (though throughout the series he has a liking to be shocked by anything electrical), when it seems the Earth will be destroyed, Sheen is only interested in winning a contest and becomes upset when he realizes the monster truck rally will be held the day after doomsday. His head is shaped like a cone. He can also play guitar, seen in the episode "El Magnifico". He appears as the main protagonist in the spin-off Planet Sheen.
Libby Folfax Cindy's best friend. She loves funk/hip-hop and electronic gadgets. Later on in the show, she received a brand-new hair makeover and a striped-pink shirt. Libby is 11, and in the first season she does not appear on the title logo, however when she becomes more involved in the show in the second season, she is added to the logo. Unlike Jimmy's friends, Libby is shown to do well in school, though isn't at the level of Jimmy or Cindy in terms of intellect. In the movie and Season 1, Libby's hair is up in a bun, with a large bang covering her eye. She wears a green dress, green socks, and black dress shoes. In the episode Beach Party Mummy, she got a makeover with her new cornarrow braids, pink shirt, blue jean pants, and brown shoes.
A Algae Men, the henchmen of Dr. Sydney Moist, a crazed scientist gone bad who lives on the ocean floor. It was later revealed that Dr. Moist was using a mutagen to turn innocent tourists into algae men, which explains the rash of disappearances in the Bahama Quadrangle. Aunt Amanda, Jimmy's wealthy aunt, she hates Jimmy Neutron because he brings danger to the town. She reconciled with him after revealing his evil, baby cousin's plan. Appears only in the episode "Clash of the Cousins". Aunt Kari, Jimmy's aunt and Baby Eddie's mother. Like the rest of Jimmy's cousins and aunts, she hates him for nearly destroying the town.

Jimmy's hormones had kicked in after that, and he had hoped for another kiss from her when the adventure was over. He and April would send messages via space rock after that. Her real name is Chee Aaaaaaaaaah Doik!, but she hates this name and threatens anyone who calls her by it. Voiced by Alyssa Milano.

They have no bodies, (yet still somehow manage to talk), and are motile only by moving their brain stalks as feet, which makes them extremely slow.

As one might guess, they usually win challenges by the use of skill and logic, rather than strength. Buford Lee Stormshuckle, the Southern American warden of a correctional facility who framed Jimmy for a bank heist. He taunts Jimmy by pseudo-offering him a glass of ice cold lemonade. When Sheen and Carl unsuccessfully tried to free Jimmy, he arrested them too. However, Jimmy and his friends blinded him while trying to escape. He looks in Retroville for them near Cindy Vortex's house with his boom box (apparently budget cuts made it so that he could only afford a recording of dog barking instead of a real search dog). Jimmy, Sheen, and Carl sneak into Cindy's house after there was a reward for 10,000 dollars which she had to call 555-55555555. Cindy was definitely going to turn them in, claiming there was a lot she could do for $10,000. Sheen commented: I'd start with your room.
