6. Danny Phantom
Danny's parents are obsessed with hunting ghosts and have created a Ghost Portal to bridge the gap between the Ghost World and Earth. While exploring the machine, Danny accidentally presses the On button causing him to become half boy, half ghost and it is up to him to save his town from ghost attacks using an array of super powers such as flight, his ghost ray and ghost wail. The show itself mixed in humor and gave us a cartoon character with awesome powers and a wide variety of antagonists to keep the show feeling fresh.
