Hal M. Denmark
A self-proclaimed computer genius from the Clark Computer Company in Jupiter's Moon, Europa. He has been known to steal secret government information which gave him a bounty on his head. Suddenly, a bio-nuclear war in Europa, which spread a certain zombie virus, suddenly sprang up. Fortunately, he used his secret government information to obtain a vaccine from the said virus. Later, Europa was abandoned and Hal was thought to be dead for 5 years.
Currently, he lives in an underground stronghold spending his days trying to look for any trace of humanity left in Europa using radio signals.
Because he has been alone for quite a long time, he spends his spare time playing computer games, reading comics/manga, or watching cartoons/anime. This made some sort of psychological effect on him which drove him to a certain level of eccentricity.
