Overview:

Martin Mystery has a passion for all things paranormal. When he's not at school, this teenage lover of supernatural ooze works undercover for a secret bureau specialising in mysterious phenomena. Together with his older stepsister Diana, Java (a massive caveman lost in time) and Billy (a small green hovering creature), he checks out weird wonders. Martin is always bursting with energy and seldom thinks before he leaps. Diana is his guardian angel – a straight-A student, she brings the brains to their missions. Seen a zombie, alien or ghost?
