he series reimagines the title character Martin Mystery and (now his stepsister) Diana Lombard (after Martin's mother's death, Martin's father married Diana's widowed mom) as 16-year-olds attending Torrington Academy, a high school in Sherbrooke, Quebec. They work for the covert organization "The Center", which secretly protects the people of Earth from extraterrestrial and supernatural threats. Like all secret organizations, they must keep their work secret, thus anyone who comes too close to their missions, i.e. seeing a monster, will have their memories of the event erased. Not everyone who works for the organization is human. The short and green-skinned alien, Billy, is one of Martin's best friends. Java works as a lunch server of Diana and Martin's school and is a caveman from 200,000 years ago; he also aids Martin and Diana on their missions.
