If the cute, chubby, and translucent Casper from way back is the only friendly ghost you know, then you must meet Danny Phantom.
Danny Phantom is an animated television series shown on Nickelodeon and was made by Butch Hartman. The show was produced by Billionfold Studios and focuses mainly on the life of a 14-year old boy who is half-ghost and half-human.
Daniel "Danny" Fenton is similar to many teenage boys- clumsy, unpopular, and often the target of bullies in school despite having a good nature. Danny's parents are Jack and Maddie Fenton who are ghost hunters. Jack and Maddie are rarely seen without their orange and blue jumpsuits respectively. They believe that all ghosts are a nuisance to society and must be destroyed.
One fateful day, Danny decided to explore the laboratory of his parents due to the constant persuasion of his best friend Sam. He stepped into the Ghost Portal which his parents made to connect the real world to the ghost world or Ghost Zone which is considered to be Earth's parallel universe. Due to an accident, Danny was infused with "ectoplasm" which caused him to be half-ghost.
Danny was astounded with what happened and initially did not know what to do with his newly acquired ghost powers. Eventually, he decided to use his powers to save their town, Amity Park, from the attacks of evil ghosts from Ghost Zone. People hated him at first but they realized later on that Danny Phantom is good-natured and is dedicated to protecting them.
Danny's best friends Sam and Tucker know about Danny Phantom. They often help him in his quests and battles. Danny's sister Jazz, also known as Jasmine Fenton, also discovered the secret identity of Danny Phantom.
During the early stages of the show, it was implied that Danny seeks popularity as he is an unpopular kid in school. When he became Danny Phantom, he faced the challenge of not letting the fame go to his head, especially when he acquired the "superhero-ghost status".
As the story progressed, Danny learned many lessons and learned how to be responsible as a human and as a superhero-ghost. He constantly faced the difficulty of hiding his ghost identity from people, especially from his parents who have a negative perception about Danny Phantom. He learned about love as he fell in love with Sam who eventually became his girlfriend.
Because of his decision to protect the town and the people who hate him, Danny Phantom faced many enemies- ghosts and humans alike. His ghost enemies include The Box Ghost, Johnny 13 and Shadow, The Fright Knight, The Ghost Writer, The Lunch Lady Ghost, and Vlad Masters or Vlad Plasmius. His human enemies include The Guys in White, The Masters' Blasters, Freakshow, and Valerie Gray who used to be his love interest. Because of the character's popularity, many Danny Phantom games and products have been produced. Danny Phantom games abound as online flash games but there are also various Danny Phantom games for different gaming platforms such as Danny Phantom: The Ultimate Enemy and Danny Phantom: Urban Jungle.
