Martin Mystère is both the name and protagonist of an Italian comic book. Created by writer Alfredo Castelli and artist Giancarlo Alessandrini, it was first published in Italy by Sergio Bonelli Editore in 1982.
It is still published in Italy and has been translated in many other languages, sometimes with the name changed (e.g., in Germany, the series is named Alan Dark; in the United States, Martin Mystery/Martin Mystère; in Serbia, Marti Misterija, in Croatia, Martin Mystère, and in Turkey, Atlantis; Marma Manithan Martin in Tamil, South India).
Martin Mystère is an art historian, archaeologist, anthropologist, adventurer, writer, television producer, and collector of unusual objects. Based in New York City, where he was born Martin Jacques Mystère, he spent much of his early life studying in Italy, where many of his adventures take place. After the unexplained deaths of his parents in a plane crash (1965), he started to devote his studies to the most enigmatic events and places of human history. He also helps the New York police and a United States secret government agency in their investigations, as well as anyone who comes to him for help and gets him curious. He is assisted in his adventures all around the world by Java, a mute and very strong Neanderthal man he discovered in the hidden City of Lucid Shadows in Mongolia.
Java is Martin's closest friend and helper. He is a Neanderthal man found in a lost city of Neanderthals. He adapted to modern life. In the early series, he mostly followed or found people or things with his instinct or animallike sense of smell; later, he became more normal but lost effect on the stories. Now he mostly follows Martin everywhere, protects and helps him.
Martin Mystère's main opponents include the Men in Black, the controversial art patron Sergej Orloff, and Mr. Jinx.
Two other antagonists of the series are Loki and Morgan Le Fay.
His companion is Diana Lombard, who is also his long-time fiancée, later his wife. Mystère is not a womanizer, but he has not always been faithful to Diana either. Diana is a social worker, angry with Martin because he often travels without letting her know in advance, and he is surrounded by beautiful women.
Together with Sergej Orloff, he was educated by the guru Kut-Humi. Sergej and Martin were friends and after their education they received the weapons called Murchadna (ancient ray-guns from the lost Mu). However, their friendship ended after Sergej chose the evil path; his weapon can kill whereas Martin's Murchadna can only make the target faint when blasted. Murchadna lost its power later, but showed up a few times more.
The Men in Black are a secret group spreading over the whole world and their aim is to prevent people from learning the true history of the world. The group was founded by Adam an Atlantean agent, after the great war between Atlantis and Mu. The main aim of the group was to protect mankind from such disasters. After centuries, the organization became corrupt and endeavored to keep the true history of man unknown. The group destroyed all traces of Atlantis and Mu to maintain "world order" in line.
Another secret group called "Elsewhere" is a United States secret government agency. This group was founded by Thomas Jefferson. Their aim is to save mankind and collect and hiding secret and marvellous things. Sometimes they fight The Man in Black, but sometimes they work together. The main contrast between them and The Man in Black is, they don't destroy fantastic objects and beings. They protect and hide them, until mankind is ready to learn.
Kut-Humi is a wise man who has a relationship to Agarthi, which is "a city both in this world and not" (this can be explained as being a utopic city). He has taught Martin and Sergej on spiritual issues. He shows up when needed and guides Martin.
