Felix Faust

Felix Faust is one of the most powerful sorcerers in the world.

History
Klarion summoned several sorcerers, including Felix Faust, to perform a spell that could split the world in two dimensions, an adult and a child dimension.

Wizard and the other sorcerers guarded the pentacle in the adult dimension. When the Justice League arrived, he bombarded Red Tornado with fireballs, 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.
