text: Characters Martin Mystery (voiced by Sam Vincent; Alexis Tomassian):
  Martin is a 16-year-old Canadian boy, with a passion for monsters and the paranormal, who works as a paranormal investigator for "The Center". He is immature, hyperactive, and zany, constantly bursting with energy. He is usually an underachiever in school, once getting 106 out of 902 on his pre-college aptitude test. While impulsive and impatient – often leaping into danger on missions without thinking to help those in peril – he consistently proves to be a quick thinker and clever. He has a peculiar love for everything slimy, sloppy, and gooey – things that make Diana gag.  His favorite pastime is taunting Diana by playing practical jokes. A running gag in the series is his constant flirting with every beautiful girl he meets, who usually reject him.
  Martin jumps to conclusions very often, coming up with every unlikely theory he can think of, usually from some horror movie or monster movie he saw, or from his subscription to Paranormal Monthly. As the leader of the trio, Martin is also the only one who wears a U-Watch. His first monster was Venoso, a female chameleon monster that has the power to shape-shift into any person it wants.
