Dr. Fate's helmet provides power for all of his spells, and makes him one of the most powerful known sorcerers (though his power is still dwarfed by that of the Spectre). He is capable of nearly any magical feat, but the following effects are some of his most often used.
Dr. Fate can fly at Remarkable speeds, even without wearing his helmet.

Archaeologist Sven Nelson and his son, Kent, then a boy, were exploring an ancient temple in the Valley of Ur in Mesopotamia. Kent found the entombed body of the giant ancient wizard Nabu the Wise, who was in suspended animation. Nabu was actually a being composed of pure energy who had originated a half million years ago on the planet Cilea and had taken human form. He was revived by a gas that killed Sven Nelson. over the following years Nabu trained Kent in sorcery. Finally, when Kent reached adulthood, Nabu presented him with a helmet, a cape, and an amulet, and, naming him Doctor Fate, sent him back to the outside world to battle evil. On his way to America, Doctor Fate first met Inza Cramer, who eventually became his wife. There, Doctor Fate became founding member of the Justice Society of America.
Nelson came to realize that when he donned his helmet, his personality was being increasingly supplanted by that of Nabu, who was a mystical "Lord of Order." Hence, Nelson put the helmet aside, thereby greatly reducing his powers, and instead wore a different helmet that did not conceal his entire face as the original had. Doctor Fate thereafter joined the All-Star Squadron, and months later, his original helmet was stolen by the sorcerer Kulak and hurled with him through "an infinity of dimensions."
Under circumstances yet to be revealed, however, Doctor Fate regained his original helmet and began wearing it whenever he went on a mission. Now, whenever Nelson puts the helmet on, his psyche is entirely replaced by that of the Lord of Order Nabu, although the later retains Nelson's memories. Doctor Fate continues to be an active member of the Justice Society of America.
