Bruno Mannheim, nicknamed "ugly" is the leader of Intergang, an organised crime outfit headquartered in Metropolis. He rose to power by allying with Darkseid and securing high-tech Fourth World weapons from Apokolips. After the Infinite Crisis, Mannheim found new inspiration in a crime cult built around the worship of Cain - the first murderer. Mannheim's devotion to the teachings of the "crime bible" led him to committing unspeakable atrocities, including human sacrifices and cannibalism.
Believing that the crime bible demanded the ritual murder of Kate Kane (Batwoman) Mannheim kidnapped her until stopped by the arrival of the Question and Renee Montoya. Months later Mannheim reemerged in Metropolis, apparently grown to the size of a giant. After zeroing in on the beat of Mannheim's over-sized heart, Superman disrupted the criminals' organisation but couldn't prevent him from teleporting to safety.
Mannheim's known connections with extra terrestrial weapons dealers combined with his new focus on the immoral cult of Cain, have resulted in a crime lord with unlimited power and no moral scruples. Mannheim is now far more dangerous than he has ever been previously.
