Martin Mystery

This Canadian series re-imagines the comic books' main characters (Martin Mystery and Diana Lombard) as 16-year-old step-siblings attending Torrington Academy, a high school in Sherbrooke, Quebec. They work for a covert organization known as "The Center," which covertly protects the people of Earth from supernatural threats. Their allies at The Center include Billy (a small, green-skinned alien), who is one of Martin's best friends, and Java (a caveman from 200,000 years ago), who works as a janitor at Torrington Academy. Martin's vast knowledge of the supernatural and his remarkable intuition make him a valued agent of The Center, and compensate for his huge ego and poor personal hygiene. Diana resents these flaws at times, as Martin often does not seem to understand the seriousness of his missions, but generally loves him like any sister
