Name: Kaspar Geilbrück
Appearance/race: Average height, broad-shouldered and bulky. His head is shaved regularly, revealing a pale and pitted cranium. Typically wears heavy canvas work pants around worn steel-toed boots, along with a dime-a-dozen white synthetic cotton tee. Seldom seen in public without his oversized nylon security services jacket, which has long since faded to gray and acquired a thorough coating of grime.
Age: 20
Brief history(optional): [i]Kaspar grew up in the Mitwohnung sprawl on the eastern periphery of the Metro, where the gray concrete towers extended as far as you could see in any direction ( at least until they hit the perpetually and equally gray sky ). While he had all his basic needs provided for by the Planetary Administration, he could not escape the feeling that he would have preferred to live in a time when humans earned their own way and were masters of their own world. When a friend of a friend with similar ideas asked him to carry a package deep into the heart of the Metro, he gladly accepted the opportunity to do something of worth with his life. But with the events of the past week, he has been stranded far from home and outside his comfort zone.[/i]

Traits: Reserved but polite; Acquainted with violence; Carries himself with a pride that belies his apparent desperation.

I think this could be pretty interesting, especially if we explore the deteriorating situation/slide into war aspect of it rather than just jump to the explosions. I'm not sure how far-future you were thinking, but I got the sense of somewhere before the year 3000, where fantastic tech exists but isn't widely available on a backwater like earth ( humanity's own technological advancement immediately stagnated when it was exposed to other species' vastly superior knowledge ). I also imagined a future that isn't dystopian, but it isn't all flying cars and robot butlers either; My character pretty much only works if there are significant parts of the population whose lives are stable but fairly bleak/unfulfilling.

BTW I'm pretty new to this, so please feel free to point out if I make mistakes.
