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 from 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.
