History
Demongo was a long-term minion of Aku, who summoned him from the Pit of Hate. He was sent to destroy Jack and enslave his essence. After his defeat at the hands of Samurai Jack, Aku imprisoned Demongo in a crystal skull. Demongo begged for forgiveness, but after a mere moment's consideration, said, "no," and smashed the skull.
