Felix Faust is a tall Caucasian male with a lean face and deep eyes. He wears a headdress made up of a golden coronet and black cloth covering his hair and part of his cheeks. He wears a black long sleeve undershirt that goes up to his neck, with large metal bands on his torso. Over it, he wears a blue tunic that goes up until his knees, and is held in place by a golden sash.
Faust and the other sorcerers guarded the pentagram in the adult dimension. When the Justice League arrived, he bombarded Red Tornado with fire blasts, and even managed to throw him back, if only for a little while. He was taken out by Doctor Fate after the worlds were merged back together.
Felix Faust was one of the first villains of the Justice League, first appearing in Justice League of America #10. He sells his soul to demons to gain powers, but over the years, has grown substantially weaker.
This is Faust's fourth animated appearance. He first appeared in The Super Powers Team: Galactic Guardians; after that, he appeared in the DC Animated Universe (Justice League and Justice League Unlimited), and Batman: The Brave and the Bold.
