Marco Owen

Marco Owen is the male main character of the series. He is a fearsome-looking man with a muscular frame and many intimidating tattoos all over his body who is also an expert hacker, so much so that he was able to crack through the CIA's computers – and those of Venus Gate, something that had him arrested and incarcerated for more than half a century (during the events of the manga, he still had 60 years to serve in prison). While a prisoner he was approached by the NSA, which offered him complete parole for his crimes in exchange of his help in dealing with the Medusa affair. Becoming a de facto spy for the United States, he was sent as a patient to the gathering at Venus Gate labs, the same where all the other main characters were sent, in order to assess the objectives of the gathering, gather evidence on the mysterious Level 4 labs of the island, and also to pursue a personal vendetta against his old friend Zeus, who framed him for crimes he did not commit before vanishing.
