Spoiler (click to show/hide):
Genetically speaking, Marco is the illegitimate child of Senator Phil Grates' daughter, Teresa Grates, who had been abducted by a syndicate during her foreign relations visit to Mekazikstan, and held for ransom. Marco's father - if one could even qualify the man as a father - was one of the syndicate members, who got bored of merely guarding the hostage, and raped her one day in a fit of sexual frustration. While she indeed hated the man, Marco's mother never faulted the son for his father's sins. Knowing her own father's expected reaction to the baby, she traveled in secret to a monastery, and entrusted Marco to the local clergy. Cliche? Yes...but it was better than chancing things with Mr. Grates...
Fast-forward 18 years, and Marco had grown up in that monastery, instructed thoroughly in their way of life...among other things, as the monastery itself was also a hideout for a clan of secret vigilante ninja. Known as the "Jingami" clan, their methods and technology had evolved with the ages, but the fundamentals remained the same: utilize theatrics and illusion to destabilize the enemy, then swoop in when they are most vulnerable. Marco himself disagreed with how they always killed whatever criminals they hunted down; he believed it was not their place to deal out death and judgment for crimes, especially since they'd do so for something as small as petty theft. The clan's very creed demanded it, though: "All evils, great or small, shall be slain by the Jingami."
Over time, tensions regarding Marco's thoughts on that built up unseen, until one day, when the clan brought back a young man who had been caught stealing from the nearby village's fruit vendor. He had only been doing so because his parents had abandoned him as a child, however; he had no plan to continue thievery once the issue of food-supply was resolved. In spite of that, they still demanded the boy's head for it...and they wanted Marco to be the executioner. From the very beginning, it was clear that this was a test of his loyalty to the clan. However...if this was how they did business...
"I will not."
The harsh, straightforward refusal of his own orders immediately prompted the contempt of the entire clan. Per their own creed, they drew their blades, as "to allow any evil to live is to be poisoned by that evil." The only way Marco was getting out of that place alive was by going through every single one of them...and he did, slicing through the underground chamber's support beams, causing it to cave in and kill what could be presumed was the clan's entirety. Whatever survivors may have escaped besides Marco and the young thief, the hive-mind of the Jingami's informational network - their headmaster - had perished in the rubble. They never caught back up to the dissenter, due to the head start he had in the chaos of the cave-in, as well as various track-covering tricks which they themselves had taught him. Marco Jingami, as well as the young man, were beyond their reach.
Since then, Marco settled down in the city he lives in today, having a house he shares with the young man he saved back at the monastery. That youngster was actually Maxwell Turilli, son of Tarja Turilli, C.E.O. of arms manufacturer Turilli Wares. In the time they had spent in that countryside, however, Turilli Wares had reorganized itself into a more benevolent company, dealing in software development instead of weapons. The weapons parts that they had dismantled were stored in an inconspicuous seaside warehouse, which - thanks to Marco's ex-Jingami skills - was easy to infiltrate, and over time, he and Max had constructed themselves a secret underground stash of equipment, tunneled out from beneath their own house.
Why did Marco and Max tunnel out that stash? Well, as they say, "old habits die hard."
Turns out the city's seedier side had begun to seep out from between the cracks in the wall of news reporters that valued the public's comfort over the actual truth. Muggings at night were becoming more and more common, and the muggers themselves were getting progressively ballsier with how willing they were to kill or abduct their victims after the deed. Assembling various gadgets from the scraps he and Max had gathered, Marco began a secret life as a vigilante, using the alias of "Watcher" alongside a facemask and eyepatch-like viewing lens to mask his true identity. That lens has a number of functions, such as night-vision, infrared, and x-ray; he uses it wisely to spot the muggers in their hiding places, and be ready to spring on them the moment their intentions are made clear. The people he saves are left to think of him as they so choose, whether it is as a silent guardian, a law-ignoring vigilante, or simply...a watcher. The felons he apprehends are usually restrained in some manner, and left somewhere along the city police's standard patrol routes to find, with a small note that reads: "To justice, sincerely, the Watcher." Over time, Marco and Max's two-man nighttime clean-up operations helped keep true peace in the city, and not just a fool's peace held up by truth-bending reporters. To cover their nightly operations in the public, Marco and Max run a small indie game development business. Max adds to the revenue by doing some artwork commissions on the side, as well as having a donation button on their web site. Marco does the more technical stuff in their business, such as programming and level design, which is fitting for his analytical and quiet nature.
When he received the text from S.S.I., Marco already knew something was up. He never entered in such a contest, and only after using the wonders of the Internet could he figure out who they are. This was either the biggest texting blunder he's ever seen, or someone's pulling strings for an ulterior motive...and his money's on the latter. Texting back "Yes" to accept their little proposition, he intends to unravel whatever plot this is from the inside-out. He will find the true motive behind this turn of events, and - when the time is right - he will shut down whatever nefarious operation arises in the truth's revelation.
Personality-wise, Marco's one-word summary would be "quiet." He rarely speaks unless necessary, or if it's with his longtime partner Maxwell. In fact, the only one who can make him leave the house at daytime is Maxwell himself, and it's just for bare necessities, such as grocery shopping. The fact that he is the vigilante "Watcher" has never been discovered, as doing so would both endanger Max's life and his own, and as nice as being regarded as a "hero" by the people may be, police deal with vigilantes in a much different manner. Even if he does achieve the workings of a hero, he'd prefer to remain an unsung one. Besides, the press is a major hassle to deal with, and those camera bulbs flashing would hurt his eyes.
