Martin Mystery - Season 2 (2004)

Martin and the gang are off to France to check out the mysterious disappearance of two teens on a boat ride. When they learn that one of the missing teens works at a surf shop, they head there to check it out, and find a vampire who is sucking the souls out of people. She captures Martin, who is revealed to be the descendant of her husband, and forces Diana, Billy, and Java to go and rescue him before the vampires can unleash their brethren from the Banished Realm.

At the National Museum of Brunel, a small Malaysia-like country in Eastern Asia, a robber is surrounded by a mysterious green mist before being transformed into a monster. The group is sent to investigate. They discover that they are up against a genie who wants revenge on the descendant of the man who captured her. Java and Diana are rendered helpless by the genie's power.

After an incident at the school library, Martin claims Diana is a "goody two-shoes". So, she drastically changes her image in order to prove that she can be a bad girl when she wants. At the Center, M.O.M. tells them that there was a bizarre attack on the mayor of Stillwater, Louisiana by an invisible force and sends them to investigate. After a few more weird events they discover that a corrupt politician is using Voodoo Dolls to eliminate his competition. He intends to win the mayoral race, and end up in the mayor's office, an office that was built to conceal an ...

Martin, Diana and Java are sent to a small island resort to investigate the disappearances of its guests and staff.

Looking for two missing Center agents in the Sahara strands the gang in the long lost underground city of Alpha-Omega. The Alpha-Omegans mistake the bald-headed Diana for their lost Queen named Una. She is the sign they have been waiting for to begin their conquest of the surface world.

M.O.M. and Diana decide to break Martin of his habit of always borrowing their stuff. But that is soon overshadowed by problems at the Center's base in the Canadian Arctic where Martin has the choice of co-operating with his old rival Marvin, (who blames Martin for his transfer to the frozen tundra), or becoming a host for the bodysnatching creature that has been accidentally unearthed and is growing stronger with every host it takes.

Martin's attempts at filming his own horror movie are interrupted when a giant ant emerges from the screen of the local drive-in which is showing an old sci-fi movie about giant insects. Martin and Diana soon discover a 500-year curse is bringing imaginary monsters to life, and since Java was playing the creature in Martin's movie he has been transformed into a real radioactive swamp zombie. To make matters worse, if the monsters are not all defeated by sunrise they will become indestructible, and Torrington Academy will never be rid of them.

While Marvin has left Torrington, Martin is irked that everyone "particularly Jenny" is still talking about him rather than paying attention to his extreme sports stunts. So his jealousy kicks into overdrive when he discovers that M.O.M. has made Marvin a Center agent and assigned him to work with Martin and Diana on their latest mission to investigate odd incidents at the Scopes Institute "a school for the blind", located in British Columbia. With Marvin out to flaunt his superiority, Martin seething with jealousy, and Diana drooling over Marvin, is anyone on the ...

While sick with a mysterious illness, Martin, Java, and Diana are quarantined in the Center's medical wing and reminisce about their past adventures. Due to a misunderstanding, they think M.O.M has decided to terminate them before they can spread the sickness. They flee deeper into the Center unaware that the real cause of the alarm is that the Bogeyman has escaped and they are heading right for him.

When M.O.M. fails to return from her vacation in Jamaica, Billy calls in Martin, Diana, and Java to investigate "despite the fact that Martin has been temporarily suspended from the Center". They uncover what M.O.M. was really up to -- she was on a secret mission to unlock the Gateway to the Underworld.

It is the final episode of the season and things are looking pretty final as monsters appear all over the world and overwhelm all the Center's agents, while the now evil M. O. M. And the Gatekeeper unite to destroy the gang.
