Carlos "Loso" Blacksun, Born Charles Moran Connolly, was the youngest, and only American son of Mary Connolly, an Irish immigrant, who had absconded with her two young boys and moved to South Philadelphia to escape her abusive husband. The boy had been cheekily named Charles after Mary's father, an established and very successful investor, who disowned her, caring not for the hellish existence she endured but rather for the negative impact on his bottom line as her husband had been a long time business partner and he had greatly "encouraged" her to marry him in the first place. It was in Philadelphia where Mary met Diego Alejandro Montenegro, a Mexican immigrant who lived across the hall from her and ran a small eatery on the first floor of their apartment building. Mary and Diego fell in love, and it wasn't long before Mary gave birth to her third son, Charles. Her father never accepted young Charles as a member of his family, refusing to use his name, eventually taking to calling him "Carlos" due to his "impure heritage."
The first few years of Charles' life his home was filled with love. While Mary's first two boys, influenced heavily by constant contact from their Grandfather, never accepted Diego as their Father, Diego was never-the-less a great father. Calm and wise, Diego's sage-like wisdom would shape and guide Charles into becoming an honorable young man. An exemplary student, respectful and appreciative, young Charles was bound toward a bright future, until one stormy September evening everything changed. Two weeks before the start of his junior year of highschool the unimaginable happened. While closing up that night, three men had entered the restaurant. Diego, kindly explaining he was closed for the evening, had offered to send the men home with some leftovers if they were very hungry. These men however, weren't at Diego's for the famous tamales, these men were out for blood. They demanded Diego sign over his business to their "organization", claiming Diego had no right to operate in an Irish neighborhood as a Mexican, and when he refused the three men beat him to death in his own kitchen. It was Carlos, coming down as he always did in the morning to have breakfast with his father before walking to school, who found him there.
Mary would never recover from the devastating loss. She herself took to the bottle, and eventually the needle before she too passed nearly 2 years later, a victim of grief and hopeless despair. Upon her death, the two older boys, now college aged and well aligned with their wealthy grandfather returned to Ireland to claim their birthright, a place at Grandfathers Investment Firm, while young Charles was left to spend the final two years of his adolescence alone, in foster care, before being released onto the streets on his 18th birthday. Unable to cope, young Charles had dropped out of school having never attended a single day of the 11th grade. Homeless and destitute, he had enlisted in the United States Marine Corps with a new name - Carlos, the black son. After completing basic, Carlos found himself dispatched to Elektrozavodsk, where he fought valiantly to defend the city from the infected. As the city was over-run, Carlos yet again found himself alone, left to fend for himself in the harsh reality that was now life after the death of society as we know it.
