The series Danny Phantom centers on young Daniel "Danny" Fenton and his coming-of-age story as a half-ghost superhero in the town of Amity Park. He gradually grows, bettering himself and his powers over the course of the story as he deals with ghosts, balancing his normal and heroic life, a community that does not initially trust him, and later, fame and praise from across the country.
His companions are his best friends: Sam Manson, a vegetarian goth girl who is entranced by the "weird and supernatural" and Tucker Foley, a lighthearted "techno-geek". Danny often has to put up with his eccentric ghost-hunting parents, Jack and Maddie Fenton, and his smothering, doting, but compassionate older sister, Jazz Fenton. His primary nemesis is Vlad Masters, a billionaire celebrity who is also a half-ghost.
|Daniel "Danny" Fenton / Danny Phantom||"Mystery Meat" (episode #1)||
Danny Phantom (David Kaufman) is the main protagonist of the series. He is initially shown as an average, shy, insecure, self-conscious, yet good-hearted  14-year-old boy who was desperate to fit in with his peers and be accepted. After an accident in his parents' ghost lab, he becomes a human/ghost hybrid, and obtains a variety of ghostly abilities. A battle with the Lunch Lady Ghost placed the unsure Danny on the path to becoming a superhero. Despite his flaws, he is loyal to his friends and family. He eventually grows, gaining great confidence in himself and maturity, and begins concentrating more on his heroic duties.
He's constantly under pressure from his arch-rival Vlad Masters, who wants nothing more than to have Danny as his son and apprentice, a desire which is proven in a few of the episodes. His attempts are futile, though, and he remains Danny's enemy.
Hartman originally envisioned Danny as a normal human who hunted ghosts. Accompanying him would be an owl named Spooky and his means of travel would be a motorcycle; Hartman paid tribute to the latter later in the series. He and Sam also were meant to share a psychic connection, but this idea was discarded as it would have made Danny and Sam seem too developed for a show that was only just starting.
|Samantha "Sam" Manson||"Mystery Meat" (episode #1)||Sam Manson (Grey DeLisle) is one of Danny's best friends. She is a Jewish-American girl who is also an environmentally-concerned "ultra-recyclo-vegetarian". Her parents are well-to-do social conservatives who inherited money from their famous inventor ancestor, who invented "the machine that twirls the cellophane around the toothpicks", though she briefly kept this a secret from her friends to avoid "fake friendships".
Sam is often the most pragmatic of the group, but she can be bossy at times and is determined to stand up for what she believes in, particularly when environmental causes are involved. Like Danny, however, she is good-hearted, as she is always there for him no matter what. She was the one who urged Danny to explore the then-under-construction Fenton Portal, resulting in the accident that gave Danny his ghost powers. She has a crush on Danny that lasts throughout the majority of the series, and she eventually becomes his girlfriend.
Sam has also been unintentionally responsible in the development of ghosts and was transformed twice. In "Parental Bonding," when attempting to retrieve the Amulet of Aragon from Paulina to stop her from turning into a dragon, Paulina puts it on Sam as she tells him she only faked affection for Danny to get back at Sam, which infuriates Sam and transforms her into the ghost dragon, who Danny is able to defeat and change back. In the episode "Urban Jungle", Undergrowth brainwashes Sam into becoming his queen and "personal care taker of everything green". In the episode "Memory Blank", Sam causes Danny to lose his powers out of anger because of the wish-granting ghost Desiree and also brings to life three ghosts from a horror movie, Femalien, Terminatra, and Nightmerica.
|Tucker Foley||"Mystery Meat" (episode #1)||Tucker Foley (Rickey D'Shon Collins) is an African-American boy who is Danny's other best friend "since forever". He is the most lighthearted of the trio and often cracks jokes, serving as the comic relief during very tense scenes. He often believes he is a ladies' man, but often fails at attracting any popular girls. Gifted with technological knowledge and a self-proclaimed "techno-geek", Tucker often helps by using his PDA to hack into computers and machinery. He is also a lover of meat, as opposed to Sam.
Despite all this, Tucker has a shockingly dark side; he tends to get easily corrupted by his vice, and while he enjoys getting attention, he openly expresses envy when he is not receiving any.
|Jasmine "Jazz" Fenton||"Mystery Meat" (episode #1)||Jazz Fenton (Colleen Villard) is Danny's 16-year-old sister. Viewing herself as the most rational and normal member of the family, Jazz often plays a surrogate parental role to Danny, thinking he's a naive child in need of guidance, unaware that she is often smothering him. Due to her cherished goal of being a psychologist, Jazz has a bad habit of getting into people's personal space.
When she secretly discovers her brother's secret identity, Jazz has made excuses for him while he went out to fight ghosts, and slowly starts to realize that her brother is growing up fine on his own. Along the way, she learns to appreciate her family's ghost hunting and actively takes part at times. She has also learned to embrace her sixteen-year-old self instead of acting like an "adult in a teen body".
|Jack and Madeline "Maddie" Fenton||"Mystery Meat" (episode #1)||Jack (Rob Paulsen) and Maddie (Kath Soucie) are Danny and Jazz's parents. They are professional yet bumbling jumpsuit-wearing ghost hunters who make it their hobby and goal to study and eradicate "all things ectoplasmic." While they serve as much embarrassment to their children, they are just as well respected and loved by them. Despite their obsession with ghost hunting, Jack and Maddie are loving parents who dote on their kids constantly.
Jack is the most obsessed with ghost-hunting. He jumps into action before thinking and can make a bad situation even worse. While he can often act clumsy and incompetent, he holds a great deal of courage and is an adequate fighter, at one point clashing toe-and-toe against Vlad Plasmius and defeating him, much to the latter's surprise and embarrassment. He is a self-proclaimed scientist who has a good amount of technical knowledge, and is able to conjure up ghost gadgets and defense systems built all around the Fenton household. He also has a maturity and seriousness that few people recognize and can get serious and show great skill when danger threatens his loved ones. In Pt. 2 of the "Danny Phantom Ten Years Later" video on YouTube, Butch Hartman admits he partially based Jack off Fred Flintstone.
Maddie (short for Madeline) is an accomplished ninth-degree martial artist who serves as Jack's partner and equal inventor of Fenton anti-ghost gadgets. She dons a jumpsuit hood with goggles and is more down-to-earth than her husband and often supports or keep her husband from getting into trouble or harm. She is often the more sensible of the two, but can be aggressive and snappy at times.
|Amorpho||"Forever Phantom" (episode #45)||Amorpho (Danny Mann) (A parody of the Chameleon) is a ghost that is able to change his appearance into any human being or animal whenever he wants. More mischievous than malevolent, he desires to get attention by morphing into someone else and playing pranks, and later have the real person take the blame for what he did.|
|Box Ghost||"One of a Kind" (episode #3)||The Box Ghost (Rob Paulsen) is a running gag ghoul with a Canadian accent who constantly fights with cardboard and anything square (and the occasional bubble wrap). He is incompetent in his attempts to scare people and is barely taken seriously by either the heroes or the other ghosts. He was almost successful in taking over Amity Park by using Pandora's Box, but failed. Despite it, Box Ghost remains determined regardless, shouting quotes such as "Beware, for I am the Box Ghost!" when approaching foes. In an alternate future portrayed in "The Ultimate Enemy", he is married to the Lunch Lady Ghost and has a daughter with her (Box Lunch).|
|Bullet||"Public Enemies" (episode #15)||Bullet (Daran Norris) is Walker's second-in-command. He is only seen in minor roles in two episodes.|
|Dark Danny||"The Ultimate Enemy" (episode #27)||Dark Danny Phantom (Eric Roberts), also known as Dan Phantom, is a villain created by the fusion of the ghost-halves of Danny Phantom (the show's protagonist) and Vlad Plasmius (his arch-enemy) in an alternative timeline. He was created with the intent that Danny's worst enemy would be an evil version of himself. Dark Danny is a cruel, malicious ghost who cares little for anything other than himself, causing as much destruction as he sees fit.
Dark Danny, or Dan Phantom, came to be after a fatal and accidental explosion of the Nasty Burger's boiler and Nasty Burger Fast Food Restaurant that caused the explicit death of Danny Fenton's family, friends, and teacher. Grief-stricken and guilty, Danny moved in with Vlad Masters, feeling that only he could understand his pain. Danny asked Vlad to remove his emotions. Honoring the boy's wishes, Vlad separated Danny's human half from his ghost self, but then the latter retaliated afterward and did the same to Vlad. The ghost half of Danny then attempted to overshadow Plasmius, and ended up fusing their two bodies together. Plasmius's ghost half overwhelmed Danny's ghost half, creating an even more evil and powerful version of the two halves. He then destroyed and blew up Vlad's entire castle and his own human half.
He spent the next ten years destroying the world. Through complex time travelling and the help of Clockwork, the present-day Danny managed to defeat his evil self with the element of surprise, using his newly acquired Ghostly Wail- a power that Dark Danny only manifested shortly before he came back in time- against him. Dark Danny is currently trapped in a Fenton Thermos in Clockwork's lair.
|Desiree||"What You Want" (episode #6)||Desiree (Peri Gilpin) is a genie-like ghost who travels the world granting anyone's deepest desires. Unfortunately, while compelled to grant any wish she hears, she is free to interpret and twist it any way she sees fit. "So you have wished it, so shall it be!" is her sly response to a casual wish, with disastrous consequences that often serve to increase her powers. Her vindictive nature stems from her life as a human where many years back, she was a harem girl who won the affections of a sultan. He showered her with whatever gifts her heart desired, but was banished by the Sultan's jealous wife. She died of a broken heart (and old age), and returned as a genie/wishing ghost.|

She thirsts for attention and has a seductively cutting, sarcastic personality. For this, she gains power when people say her name, as is shown in her first appearance when she attempted to gain power by performing her song "Remember" live and broadcasting worldwide in the hope that everyone would chant her name at the same time and empower her. She is somewhat similar to a siren, as she can also hypnotize her victims, using her guitar as her main mode of hypnotism as well as a weapon.
Ember is known for teaming up with other ghosts to show off her divine ghost powers. In the series, she has teamed up with Kitty, Penelope Spectra and Youngblood on several occasions, usually attacking authority in society. In the episode "Girls' Night Out" she is shown to be dating Skulker.

|Ghost Writer||"The Fright Before Christmas" (episode #28)||The Ghost Writer (Will Arnett) is an author who resides in the Ghost Zone. He can create anything by simply typing on his keyboard with the added effect of forcing everyone to speak in rhymes, a situation that can continue even upon its destruction.

Breaking the Ghost Zone's Christmas Truce, Ghost Writer tormented Danny until he learned his lesson. He was later jailed for breaking the law.|

Scott Bullock) is the mummy-like spirit of an ancient minion of King Duulamun, an Egyptian pharaoh who shares a remarkably similar appearance to Tucker Foley.

He has the ability to control and merge with all electrical technology, a supernatural power known as technopathy, as well as manipulate electricity.

|Vlad Masters / Vlad Plasmius||"Bitter Reunions" (episode #7)||
Vlad Masters/Vlad Plasmius (Martin Mull) is the archenemy of Danny. A rich, debonair billionaire, Vlad is a powerful half-ghost scientist whose twenty years of experience constantly one-up Danny's ghostly abilities. As the main antagonist in the series, he vows to destroy Jack for giving him his ghost powers, which in the process injured him terribly and put him in the hospital for seven years with a fatal condition known as "Ecto Acne", thus ruining his life. He also has goals to obtain Danny as his son and, later, torment him after one too many rejections.
Vlad is a devious man whose exterior charm hides a manipulative interior. He is sneaky and often uses the people he knows as pawns to get what he wants. He remains clever and intelligent throughout the series. At the end of the series he reveals his ghost side, Vlad Plasmius in an attempt to secure world domination, but fails and is left as a wandering space nomad.
Originally devised as a vampire before the developers declared it "too occult", Vlad's current resemblance shares much in common with vampiric traits. His ghost surname, "Plasmius" is devised from "plasma" which doubly can be a reference to "blood" or ectoplasm - underlining both the former vampire element and the current 'ghost' connection. Regardless of its influence, it is a surname that stayed in the final production. However, writer Steve Marmel declared the name "Vlad Plasmius" was from a brick he bought in Lambeau Field. Vlad's love for the Green Bay Packers is attributed and added due to Marmel's fondness for them. Their team color is a reverse gold and green to avoid copyright infringement with the actual team. An original running gag would be that Vlad would lose his manor due to unfortunate luck every other episode. In the Danny Phantom 10 Years Later Part 2 YouTube Video, Butch Hartman reveals there is a brick at Lambeau Field with Vlad Master's name on it.
|Vortex||"Torrent of Terror" (episode #44)||Vortex (Dave Boat) is a psychotic ghost with the power to control the weather, a gift he considers to be an art form. He finds Earth to be a meaningless planet, and has wrought havoc on it throughout the ages. On a trial by the Observants for his reckless behavior, Vortex is freed by Vlad who used him to his own services. However, Vortex rebels against Vlad and conjures up violent weather all over the world until Danny defeated him, gaining and losing Vortex's climate control powers. Vortex can generate and control storms, and the weather in general, from creating typhoons to making heat waves hot enough to melt walls, floods and winds cold enough to freeze streets in ice.|
|Walker||"Prisoners of Love" (episode #8)||Walker (James Arnold Taylor), a spoof on the name of the then-popular TV show Walker, Texas Ranger, is a very strict vigilante and warden who runs the prison of the Ghost Zone. He enjoys law and order and often commands with an iron fist; whoever so much as disobeys one rule from his law and rule book is in giant trouble. To justify his cause, he often makes up the rule as he abides by them and is not above using dirty measures to keep the Ghost Zone clean and corruption-free.
As an act of revenge for causing a riot in his prison and allowing prisoners to escape, Walker turned the entire city of Amity Park against Danny Phantom, forcing the ghost boy to endure the city's hatred until Pariah Dark's invasion reversed Danny's negative reputation.
|Youngblood||"Pirate Radio" (episode #23)||Youngblood (Taylor Lautner) is a ghost with the appearance of a young child. Obnoxious and childish, he can only be seen by children. Despite his looks, Youngblood is a keen commander and skilled in battle.|
|Freakshow||"Control Freaks" (episode #20)||Freakshow (Jon Cryer) (a parody of The Joker) is the ringmaster of the Circus Gothica, as well as the only fully human villain in the series. An entertainer for the Gothic audience, Freakshow is eccentric, full of showmanship and creativity. His family have used ghosts for their circus for years. Unsatisfied with just a showman's life, Freakshow used a magic scepter able to control ghosts and ordered them to steal goods. He went to Amity Park to make Danny Phantom a member of his performance. He succeeds briefly until Sam snaps him out of it and Danny destroys the scepter.
He is promptly jailed for his crimes. He escapes and uses the fabled Reality Gauntlet to bend reality to his whim, only to be outsmarted by Danny again. Danny successfully uses "Ghost Envy," Freakshow's jealousy of ghosts, against him and defeats him for good. Freakshow is mainly a spoof of the Ringmaster, but the Reality Gauntlet storyline makes him slightly a spoof of Thanos. His full name is Frederich Isak Showenhower.
|Guys in White||"The Million Dollar Ghost" (episode #19)||Operative K (Dee Bradley Baker), Operative O (S. Scott Bullock), Operative L (Jim Ward), Operative M (Kevin Michael Richardson) and Agent Alpha (S. Scott Bullock) are members of a secret governmental organization whose goal is to eliminate all ghosts and other paranormal beings on Earth. Colloquially referred to as The Guys in White (spoofing the Men In Black), they are usually represented by Operatives K and O, who are tasked with capturing Danny Phantom. They are often incompetent and frequently bicker amongst themselves. They are highly prepared for any task, almost to the point of paranoia. A recurring gag is that, despite their immense dedication and resources, they always fail in capturing Danny. At one point, Danny asks why they are hunting him, to which they respond that while they are aware that he's good-hearted and has good intentions, he is too powerful and unauthorized ectoplasm to walk freely.|
|Masters' Blasters||"Phantom Planet" (episode #52)||Vid (Colleen O'Shaughnessey), Thrash (Dee Bradley Baker), and Download (Rob Paulsen) are a trio of teen ghost hunters, created by Vlad to shame Danny and dethrone him as resident savior of Amity Park.

Vlad employs her to do his bidding until she finds out that Vlad was a half-ghost and that he was manipulating her. She is hot-tempered, which often clouds her judgment, but slowly starts to realize a world beyond the superficial. She briefly strikes a romance with Danny Fenton, but clashes very often with his alter ego.|
|Clockwork||"The Ultimate Enemy" (episode #28-29)||Clockwork (David Carradine) is the Master of all Time, an immortal being who controls and keeps the flow of time. He is calm, tricky, and all-knowing. When asked by the Observants to kill Danny Fenton to prevent a future where his evil self wrecks the planet, Clockwork seemingly appears to be Danny's enemy. In reality, he is merely helping and urging him to make the right decisions so that he can prevent Danny's death by the Observants. Neutral, he does not fulfill every wish Danny desires, including altering past events. He only adjusts time as he sees fit, usually in order to teach Danny a lesson. He constantly changes his age and appearance from a child to adult to old man, which refers to his detachment from the time sequence. He currently owns the Fenton Thermos that contains Dark Danny.|
|Dairy King||"Bitter Reunions" (episode #7)||The Dairy King (S. Scott Bullock) is a ghost that used to live in Vlad Masters's mansion and now haunts it.

She first works with Vlad until Danny convinces Danielle that she is nothing but a tool to Vlad. With that knowledge intact, she sides with Danny. She shares many of the same traits and interests as Danny, who serves as something of an older brother to her. In another episode, Danny and Valerie come to help her when she was captured by Vlad. She becomes stabilized by an invention Danny uses and after saying goodbye to them, flies off to parts unknown. The last time she is seen in the series is as part of the crowd of ghosts in "Phantom Planet".|

|Cujo||"Shades of Gray" (episode #10)||The Ghost Dog (S. Scott Bullock), nicknamed "Cujo," is a playful ghost puppy. When angered, it can grow into a large, aggressive beast. In search for its squeaky toy, the ghost dog trashes the Axion Labs, costing Damon Gray, Valerie Gray's father, his job. This causes Valerie to vow a vendetta against all ghosts. After finding its toy, it disappeared.|

The battle caused her to lose the amulet, which was worn by Paulina and later Samatha and caused both of them to turn into the ghost dragon. She later made a cameo in "Prisoners of Love," briefly chasing Samantha and Tucker. Dora later appeared alongside the many ghosts fleeing Pariah Dark's army in "Reign Storm." Later she would return to the human world at the behest of her brother, Prince Aragon, who ordered her to seek out a human bride for him. She did so disguised as "Dora Mattingly," a beauty pageant organizer, and abducted Samantha due to Danny liking her. Due to the traditional role of a princess in her time, she was initially subservient to Aragon, but Sam later helped her realize that she had the power to fight against him, and she overthrew her older brother with Danny's help.|
|Wulf||"Public Enemies" (episode #14)||Wulf (Dee Bradley Baker) is a bipedal wolf ghost, constantly on the run from Walker as an escaped prisoner. He only speaks Esperanto and has the ability to go into both the Earth and the Ghost Zone at will by slashing through dimensions with his claws. Wulf retains a loyal streak and was quick to befriend and trust Danny when he helped him. In return, he sacrificed his first freedom in order to save Danny. They eventually reunite where Danny helps him a second time and secures his freedom.|
|Klemper||"Fanning the Flames" (episode #11)||Klemper (S. Scott Bullock) is a ghost seen in pajamas. He is desperate to get a friend, and continually asks "Will you be my friend?" If the subject denies him this, he turns violent and often uses an ice attack on the subject.|
|Observants||"The Ultimate Enemy" (episode #27)||The Observants (Dee Bradley Baker and Phil Morris) are a group of one-eyed ghost beings whose job is to observe the sequence of events in time. They are confined to viewing time in a linear manner, whereas their colleague Clockwork can view time in a multifaceted manner. In their first appearance, they are seen convincing Clockwork to prevent the creation of Dark Danny in the future, which they see as an inevitable event in their view of time, by destroying Danny Phantom in the present. Clockwork sidesteps this plan and helps Danny to destroy his evil self. They are also seen placing Vortex on trial in a later episode.|
Recurring human characters
- Mr. Lancer (Ron Perlman) is the vice-principal and English, Math, Science and History teacher of Casper High. He is a very strict and stern teacher who often favors the popular kids. Though he tends to pick on Danny because of his average grades and his lackluster interest in his job, Lancer is a well-meaning man who tries to make sure all his students do their best. He has a humorous habit of shouting out book titles when he is surprised in place of swear words. He also constantly tries to be "cool" by saying some rather tired "hip phrases". In the first two seasons, he acts very antagonistic, but in the third season he acts very serious and caring. He also used to be a male cheerleader when he attended Casper High.
- Dash Baxter (S. Scott Bullock) is the most popular boy in Casper High School. A star football and basketball player, he often gets free leeway from the authorities at school due to his winning streak. However, Dash is an "idiot" who frequently picks on Danny and anyone else smaller and less popular than himself. As an act of irony, his role model is Danny Phantom. His role in the series is similar to that of the Spider-Man character Flash Thompson. He makes a cameo in The Fairly OddParents episode, "Fly Boy"(voiced by Jason Marsden).
- Paulina Sanchez (Maria Canals-Barrera) is a Hispanic-American 15-year-old cheerleader and the most popular girl at Casper High School. She is beautiful yet self-centered, devious, and as Sam puts it, "a dime a dozen". Paulina is madly in love with Danny Phantom after he saved her (frequently referring to him as "Inviso-Bill"), but could not care less for his alter ego, who had a crush on her during the first half of the series. In 2017, series creator Butch Hartman confirmed in a YouTube video, "107 Facts about Danny Phantom," that Paulina's last name is Sanchez.
- Kwan (Dat Phan, later James Sie) is an Asian-American football player and Dash's best friend. Though he is popular and bullies the lesser known students as much as Dash, Kwan is a bit more reluctant. He possibly only wanted popularity so that he can feel a sense of belonging.
- Star (Grey DeLisle, later Tara Strong) is another popular girl and cheerleader at Casper High who is Paulina's best friend and also serves as her "satellite", constantly orbiting around her. She is maliciously blunt. She and Valerie are good friends.
- Mikey (Dee Bradley Baker) is a small nerd in Casper High who is often the victim of the popular boys' bullying.
- Nathan (Dee Bradley Baker) is another small nerd who is interested in Valerie.
- Jeremy (S. Scott Bullock) and Pamela "Pam" Manson (Laraine Newman) are Sam's parents and the overall antithesis of their daughter, being a pair of super-optimistic socialites. They possess an enormous disdain of Sam's nonconformity and constantly try to steer her away from it. The Mansons have a rivalry with the Fenton parents.
- Damon Gray (Phil Morris) is Valerie's father and faithful employee of Axion Labs until he was briefly fired. He is a calm, patient man who adores his daughter, but once he finds out about it, does not approve of her ghost fighting job.
- Tiffany Snow (Tara Strong) is a reporter who remains cheery despite the often depressing news she delivers.
- Lance Thunder (Dee Bradley Baker) is a weatherman who has reported about Ghosts several times. He constantly fidgets over his hair, and when he thinks he is off the air, argues with the fact that he has to be the one to report.
- Principal Ishiyama (June Angela) is the Asian-American principal of Casper High. She has a little bit of humor and is a little serious.
