Mongul

Mongul is a fictional supervillain appearing in American comic books published by DC Comics. He is an alien world-conqueror and the leader of Warworld. His brutal and merciless nature make him an enemy to Superman and a threat to the larger universe. His specialty is using the Black Mercy plants to incapacitate his opponents. Eventually he was murdered by Neron during Underworld Unleashed. His son is the second Mongul, who follows in his father's footsteps and later joins the Sinestro Corps. His daughter Mongal became the queen of Almerac until she was murdered by her brother.

Mongul was created by Len Wein and Jim Starlin, first appearing in DC Comics Presents #27 (1980).

Debuting in the Bronze Age of Comic Books, Mongul has been featured in other DC Comics-endorsed products such as animated series, video games, a direct-to-DVD movie, and merchandise such as action figures and trading cards.
