Jack and Maddie Fenton, avid ghost hunting fanatics, created a device which was meant to enter a world known as the Ghost Zone, inhabited completely by the paranormal creatures. When their device failed, their son, Danny Fenton, attempted to enter the machine. Upon entering the machine, Danny unintentionally activated it, causing him to become half human, half ghost.
Danny Phantom takes place five years after Ben 10.
The post-credits scene of this movie shows Vlad Plasmius in the Ghost Zone.
