Marv was born in The Projects and had a rough childhood. He was very protective of his doting mother, who eventually got sick forcing them to move to a better part of town. The Projects had already toughened him up, and left with it's residents as useful allys. In school his only friend was Chuck, a retarded kid who thought Marv was genious. He also got a .45 Springfield Armory M1911A1 pistol from a dead kid, and he named it Gladys after one of the sisters in school. Once he went to camp, but since then he hated nature and trees. Trees and the creepy sounds of nature were the only things that scared him.
