Doctor Fate

Kent Nelson was chosen by the Lord of Order, Nabu, to be the Sorcerer Supreme. He was raised as his apprentice, training to master magic, sorcery and the mystic arts. When he reached adulthood, he was granted the Helmet of Fate - the most powerful artifact in the universe. This granted him the title as Doctor Fate, the Sorcerer Supreme of Earth. He eventually met a woman named Inza Cramer, who he fell in love with and got married to. Doctor Fate fought mystical and supernatural threats. Especially from his archenemy, Wotan.
