Felix Faust (New Earth-Forty Three)

Origin X
Felix Faust is an immortal sorcerer, who sold his soul to a demon for magical powers and immortality around 5000 BC. Faust's main reason for his immortality is to be the greatest mage to ever live and will do anything to achieve it.

In pursuit of this goal, Faust has fought multiple mages and magical beings, including The Wizard, Shazam, Nabu the Wise, and Teth-Adam.

Faust would be stopped albeit temporally by Merlin the Wizard of Camelot and his demonic half-brother Etrigan, who banished him to a Limbo realm in the 6th Century.

World War II X
He would be free this dimension by Nazis in 1937, who were doing research in the occult and were attempting to summon demons to aid the Führer in his plan to spread his views to the rest of the world. Once free from the dimension, Faust would join the Nazi party planning to use his position to help him return to his quest.

This would lead to him learning of Doctor Fate and attempting to steal the Helmet of Fate multiple times.

When World War II began Faust was forced to help support his Führer and would have to fight Doctor Fate and other members of the Justice Society of America. During the war, the Spear of Destiny was discovered by Per Degaton, who was going to present it to Adolf Hitler, but Faust tried to steal it for himself. He managed to get it from the Per Degaton and his Nazi agents, but shortly after he did he would be defeated by the Justice Society of America and banished to another Limbo dimension by Doctor Fate.
