El Patrón

Matteo Alacrán, mostly known as El Patrón, is the main antagonist in the 2002 dystopian novel The House of the Scorpion. He is the most powerful of the drug lords, and he is also the ruler of Opium. Matt (the main protagonist) is a clone of him.

Personality
El Patrón initially seems to be friendly and sympathetic despite being apparently dangerous. He spends a lot of time caring for and protecting Matt, and he seems to have a tragic backstory; he had seven siblings who all died at early ages. However, all of this turns out to be a facade to hide his true nature. In reality, El Patrón is greedy, ruthless, sociopathic, callous, and uncaring. He utterly lacks any remorse for any evil deeds that he commits, and he is a traitor who will do almost anything to ensure his own power and survival.
