A former hit-man for the Franchetti Mafia, Jackie Estacado is the current wielder of the Darkness. Charismatic and strong-willed, Jackie is often described as among the most powerful and the most enduring hosts in the curse's long history; having held fast against its influences. He retired from Frankie's service after his encounter with Batman, which encouraged him to turn Frankie over to the authorities and retire from the mob, but at the cost of his girlfriend Jenny Romano, whom Frankie murdered in retaliation. Torn with grief, Jackie led Frankie to an abandoned warehouse soaked in gasoline and burned both himself and Frankie to death. He spent some time in Hell until The Darkness brought him back to life. He was blackmailed into working for Frankie's cousin Paulie Franchetti for some time, until he killed him as well and took control of The Franchetti Mafia. While possessed by The Darkness, he had sex with and impregnated a comatose Sara Pezzini, making him the father of Hope Estacado. He was a drug lord in Sierra Munoz along with Professor Kirchner until he was betrayed and nearly killed by The Darkness himself, casting his soul into Hell. Jackie also helped to destroy The Sovereign, but at the cost of Leonard Kim's life.
