Danny Phantom is the lead character in the show. Initially, he is portrayed as an average, introverted 14-year-old boy with a kind and sensitive nature who struggles to fit in with his peers due to his parents' eccentricities. Despite finding it annoying, Danny admires his older sister Jazz and is equally overprotective of her. Following an incident in his parents' ghost lab, Danny transforms into a half-ghost or halfa, obtaining a range of supernatural abilities. A confrontation with the Lunch Lady Ghost sets him on the path to becoming a superhero despite his initial uncertainty. Despite his flaws, Danny is a good-hearted and loyal friend and family member. As the series progresses, he matures and becomes more confident, dedicating himself to his heroic responsibilities.
Samantha "Sam" MansonEdit
Sam Manson is Danny's close friend and eventual girlfriend. She has a gothic style and is an advocate for the environment, being a strong supporter of veganism and recycling. Sam's parents are wealthy social conservatives who inherited their fortune from an inventor ancestor famous for creating "the machine that twirls the cellophane around the toothpicks." However, she briefly kept this information from her friends to avoid insincere relationships. In the Christmas special, it was revealed that Sam and her family are Jewish, which was hinted at by her grandmother calling her "bubeleh."
Tucker Foley, an African-American boy, is Danny's longtime friend. He is known for his sense of humor and often lightens the mood during intense situations. Tucker fancies himself as a ladies' man, but his attempts to attract popular girls often fail. He possesses a strong understanding of technology and refers to himself as a "techno-geek," using his PDA to hack into computers and machinery. Unlike Sam, Tucker is a carnivore and enjoys eating meat. Despite his cheerful nature, Tucker has a darker side. He is prone to being easily influenced by his vices and craves attention, expressing envy when he is not receiving it.
Jasmine "Jazz" FentonEdit
Jazz Fenton, the sixteen-year-old sister of Danny, is highly intelligent and sociable. She perceives herself as the most rational and ordinary member of the family and often takes on a surrogate parental role for Danny. However, she is unaware that her overbearing behavior is smothering him. Jazz is an overachiever and her achievements unknowingly make Danny feel insignificant and stupid, which gives him something to prove. Initially, Jazz thinks more like an adult than a teenager due to looking after her brother all her life. Danny needs a big sister more than a parent now that he's old enough to look after himself.
Jack and Madeline "Maddie" FentonEdit
Jack is particularly obsessed with ghost hunting and tends to act before thinking. He can be clumsy, but he is brave and a decent fighter. He has scientific knowledge and invents various ghost gadgets and defense systems for their household. Jack also possesses a level of maturity and seriousness that few people recognize, and he can become focused and skilled when his family is in danger. According to Butch Hartman, Jack is partially based on Fred Flintstone.
Maddie is a ninth-degree martial artist and Jack's partner in inventing anti-ghost gadgets. She wears a jumpsuit hood with goggles, which makes her resemble Catwoman from DC comics. She is more down-to-earth than Jack and often keeps him from getting into trouble. Maddie is generally sensible but can be aggressive and irritable at times.
Clockwork is a timeless entity with the ability to control and maintain the continuity of time. He possesses a composed, cunning, and all-knowing demeanor. When the Observants task him with killing Danny Fenton to avert a future where the latter becomes a malevolent force, Clockwork initially appears to be Danny's adversary. However, in truth, he is assisting and advising him to make the right choices, so he can avoid being eliminated by the Observants. Clockwork maintains a neutral stance and does not grant Danny's every wish, such as altering past occurrences. He manipulates time as he deems necessary, typically to teach Danny a valuable lesson. Clockwork alters his age and appearance frequently, ranging from a child to an adult to an elderly man, signifying his detachment from the temporal sequence. He currently possesses the Fenton Thermos, which contains Dark Danny.
The Dairy King, a friendly ghost, is one of the earliest ghosts that Danny encounters. Formerly a resident of Vlad Masters' mansion, he now haunts it and desires to be left alone. He has a unique appearance, donning a crown with a big piece of cheese under it, a white mustache and hair, a red robe, and a staff with an ice cream on it.

Dani Phantom is a clone of Danny Phantom created by Vlad to be a stepping stone to the perfect Danny clone. She poses as Danny's cousin and shares many of the same traits and interests as him. After realizing she is just a tool to Vlad, she sides with Danny and is stabilized by an invention he uses. In the end, she flies off to parts unknown and is last seen as part of the crowd of ghosts in "Phantom Planet". It is later revealed that she was adopted by the Fentons, becoming Danny and Jazz's younger sister, but this was not shown on-screen.
Frostbite is a friendly ghost who resembles a yeti and resides in the Far Frozen with his people, who revere Danny Phantom for defeating Pariah Dark.

While she can become aggressive if her box is tampered with, her namesake from classical mythology is the first woman.
Princess Dora is a beautiful princess who can transform into a dragon with her magical amulet. She first fought with Danny when she was upset about not being allowed to attend the Princess ball. Later, she made a cameo in "Prisoners of Love" and appeared alongside other ghosts in "Reign Storm." She returned to the human world to find a bride for her brother, but with Sam's help, she realized she could fight against him and overthrew and banished him with Danny's help.

In one episode, he almost succeeded in taking over Amity Park by using Pandora's Box, but ultimately failed. In an alternate future depicted in "The Ultimate Enemy," he is portrayed as being married to the Lunch Lady Ghost and having a daughter named Box Lunch.

Desiree is a ghost resembling a genie who grants the deepest desires of those who seek her help, but with a catch. Although she is compelled to fulfill any wish she hears, she is also free to interpret and manipulate it as she sees fit, often leading to catastrophic consequences. Her sarcastic response to a simple wish is "So you have wished it, so shall it be!" and her powers only increase with each granted wish. This cruel behavior stems from her past as a harem girl, who was banished by a sultan's jealous wife after winning his affections. She died of heartbreak and later returned as a genie-like ghost.
Ember McLain is a musician with a thirst for power and a disdain for authority figures. She has a sharp and sarcastic personality and gains power through the chanting of her name.

K and O are the most visible representatives and are tasked with capturing Danny Phantom. Despite their vast resources and meticulous preparations, they are often incompetent, bickering with each other and failing to apprehend Danny. They justify their pursuit of him by citing his immense power and potential danger, even though they acknowledge his good intentions and pure heart.
Vid, Thrash, and Download, a group of teenage ghost hunters, were formed by Vlad to discredit Danny and usurp him as Amity Park's hero.
