Julio 'Thumper' Torres was born and raised in Detroit, Michigan, to a Hispanic father and an African American mother. Growing up in a diverse and vibrant city like Detroit exposed Thumper to a melting pot of cultures, but it also exposed him to the harsh realities of inner-city life. From a young age, Julio also known by Thumper was surrounded by poverty, violence, and the lure of quick money. The streets of Detroit were filled with gangs and criminal activities, and it wasn't long before Thumper found himself entangled in that world. He saw the illegal drug trade as an opportunity to escape his difficult circumstances and provide for himself and his family. Thumper became involved with a local gang, running small errands and engaging in petty crimes. As he became more deeply immersed in this world, he realized that there was a vast underground market for illegal arms and drugs, and the potential for enormous profits. Thumper's ambitions grew, and he set his sights on becoming a major player in the illicit trade.
Eventually, Thumper decided to leave Detroit behind and head for Los Santos, a sprawling metropolis on the west coast. Los Santos offered greater opportunities for criminal enterprises, with its vast network of organized crime syndicates and lucrative black markets. Thumper saw it as the perfect place to establish himself as a notorious arms and drugs trafficker. In Los Santos, Thumper will quickly make connections with powerful and dangerous individuals in the criminal underworld. He will prove his worth by demonstrating his expertise in navigating complex logistics, avoiding law enforcement, and ensuring the successful transportation and distribution of illicit goods.
