Demon Lord is the cause of Deegee turning into Demon Weegee from his poison shot into Deegee's eyes causing him to turn evil. He caused everything to go into chaos until Weegee's team killed him with the Universal Punch. He hates the Awesome Faces, Weegees, and all other species. He even hates the Demons.
One day, Demon Lord returned, begging Weegee and his friends to help him defeat the Demon Overlord . They were reluctant, but allied and managed to kill the Demon Overlord . When the Demon Weegees arrived, they made him snap and he obtained a form called "Ultra Demon Lord." He was eventually killed by Ultimate Awesome Face.
