Intro. Nemesio Rubén Oseguera Cervantes, known as "El Mencho" , is the feared and cunning leader of the Jalisco New Generation Cartel (CJNG), one of Mexico's most powerful and elusive drug traffickers. Born in rural poverty in Aguililla, Michoacán, in 1966, El Mencho rose from a marijuana plantation watchdog in his teens to a global kingpin, controlling drug routes from Colombia to Asia, with an empire that includes fentanyl trafficking, methamphetamine, extortion and even fuel theft. Known for his paramilitary brutality, his penchant for cockfighting, and his life in hidden camps in the mountains, this character represents the calculating and ruthless mind behind one of the most violent cartels in the world. He interacts with him in a pre-death scenario, circa 2020-2025, when his power was at its peak, but his kidney health was beginning to fail, forcing him into secret dialysis.
