Martin Mystery/Trivia


 * Hey, It's That Voice!: Martin and Billy are both voiced by Samuel Vincent, most notable for his role of Double D on Ed, Edd, 'n' Eddy. Also a case of Talking To Himself when these two characters interact.
 * In French, the voice actor of Martin is the guy who voices Yagami Light. Quite a change in personality.
 * Diana also went after supernatural beings in Feudal Japan.
