MARTIN MYSTERY (2003-2006)
Created by Vincent Chalvon-Demersay, David Michel
Based on "Martin Mystère" by Alfredo Castelli
"MARTIN MYSTERY is a dripping goo-fest of slime, thrills and comedy, starring Martin and Diana: two mismatched teenagers with hilariously opposite personalities on a mission to investigate the weirdest paranormal enigmas and the slimiest creatures from beyond. Commissioned by 'THE CENTER' - an undercover bureau specializing in mysterious phenomena - and with the help of Java, a massive caveman lost in time, they leap from their average school duties to eerie slime-dripping caves and lairs."
