Danny Phantom

Danny Phantom centers on the life and adventures of 14-year-old Danny Fenton, an unpopular boy attending Casper High. He lives with eccentric ghost hunting parents and an overbearing older sister, Jazz. Upon pressure of his best friends, Sam and Tucker, he wanders inside his parent's Ghost Portal. He accidentally presses a button that zaps his entire body, infusing his DNA with ectoplasm, transforming him into a half ghost boy. Danny, who calls himself 'Danny Phantom' in ghost form, develops the ability to fly, become invisible, and turn his body intangible. Over time Danny becomes more powerful and develops other powers which he has to learn to control.

Danny panics over his ghost powers at first, but he soon realizes that he can use his powers to protect his town from ill-meaning ghosts. After the defeat of a Lunch Lady Ghost, Danny turns to the life of a superhero, using his powers to rid his hometown of Amity Park from the various ghosts (either entities/monsters or spirits of the deceased from another dimension) that plague it. Danny's best friends, technophile Tucker Foley and goth-minded ultra-recyclo vegetarian Samantha (Sam) Manson support Danny and help him with his ghost fighting. Aside from a variety of ghosts, Danny faces threats of many calibers, including vengeful ghost hunter Valerie Gray, other half ghost/rival Vlad Masters/Plasmius, and even his own parents--being ghost hunters, they view Danny Phantom (and any ghosts) as a menace to society. In addition, Danny tries to keep his secret safe from his classmates, teachers, and family. Throughout it all, Danny slowly realizes his own potential and his purpose, while his worlds - both the Ghost Zone and Earth - slowly begin to accept him as their defender.

• Daniel "Danny" Fenton a.k.a. "Danny Phantom" (voiced by David Kaufman) The titular character of the show. Danny is a shy 14-year-old boy who gained ghost powers from a lab accident. He later chooses to use these powers to fight against malevolent ghosts, which have begun to regularly escape the mysterious Ghost Zone and plague his hometown of Amity Park.

• Tucker Foley (voiced by Rickey D'Shon Collins): Also known as Tuck, he is a lighthearted teenager obsessed with technology and meat. One of Danny's best friends along with Sam. When not obsessing over gadgets, he obsesses over girls. Like Sam, he shares in Danny's secret and often helps battle ghosts back into the Ghost Zone. He generally provides comic relief.

• Samantha "Sam" Manson (voiced by Grey DeLisle): Danny's other best friend. Though wealthy, she chooses to hide her family's monetary success (for quite some time), in favor of being liked for who she is. A strident individualist, Sam is a practitioner of an overly dramatized fictional form of vegetarianism called "Ultra Recyclo-Vegetarianism", a frequent protester for such things as animal rights, and a self-proclaimed goth. She has a secret crush on Danny.

• Jasmine "Jazz" Fenton (voiced by Colleen O'Shaughnessey): Danny's know-it-all (and somewhat overprotective and perhaps overly helpful) older sister; a smart and highly sociable overachiever who also thinks herself as an adult. Jazz considers her parents' obsession with ghosts as a sign of needing psychological help. She discovers that Danny has ghost powers in the episode "My Brother's Keeper", but she does not reveal her knowledge of it (until "The Ultimate Enemy"), in favor of waiting until he is ready to talk about it with her.

• Jack Fenton (voiced by Rob Paulsen): Jazz and Danny's father. Maddie's husband. Jack has an obsession with destroying ghosts and expresses hate for them. He blindly goes by the belief that all ghosts are evil and not worth living, even Danny Phantom. He is generally incompetent in nature, but when provoked, can be an effective fighter. Jack cares about his family but is oblivious to Danny's powers. He also spends his time inventing gadgets that do not always work and is almost never seen without his orange jumpsuit.

• Maddie Fenton (voiced by Kath Soucie) is Jazz and Danny's mother. She is extremely smart and like her husband, finds all ghosts evil. Instead of destroying ghosts, however, she usually aims to dissect them. She is an excellent fighter.

• Vladimir "Vlad" Masters/Vlad Plasmius (voiced by Martin Mull): Danny's arch-enemy and a multi-billionaire. An old acquaintance of Jack and Maddie Fenton and one other known human-ghost hybrid like Danny. Vlad's ghost powers were thrust upon him by an accident with a Ghost Zone Portal prototype, which hospitalized him for many years with ecto-acne. He blames Jack and is resentful that his old "friend" married the love of his life, Maddie. Unlike Danny, his ghost powers are considerably more developed, and he has used them for personal gain.
• Daniel "Dan" Phantom: Danny and Vlad's mixed ghost halves due to an unfortunate choice on Danny's part. He is ten years older than 14 year old Danny and was put away in a Fenton Thermos at the end of "Ultimate Enemy". He is currently in this thermos in Clockwork's Tower.
