Powers and abilities
Doctor Fate possesses a variety of mystical powers. In general, even without wearing the Helmet of Nabu, the host can fly, is highly resistant to injury, has minor telekinesis, and has greater-than-human strength.
In all of his incarnations, Doctor Fate is an accomplished sorcerer, and at his most potent able to match most other wizards in the DC Universe.
In various incarnations, Fate can emit bolts of mystical energy, teleport across the universe, craft solid objects out of energy, and transform objects into other kinds of matter (transmutation). Prior to the events of the Crisis on Infinite Earths, he could travel between alternate Earths at will, one of a very few DC characters with this capability. The full limits of his magical skills are unknown, and have varied greatly from one incarnation to the next as well as depending on the needs of the story. For example, in Swamp Thing (vol. 2) #50 (July 1986), he slays the demon Abnegazar of the Demons Three with very little effort. Conversely in Justice League of America (vol. 1) #148 (November 1977), the Demons Three control him and set him against his fellow heroes.
At the known height of his abilities, he was able to take control of Etrigan the Demon, Darkseid, Highfather and Orion and harness their powers to take on the Anti-Life entity. In this instance, he was powerful enough to destroy a reality in order to halt the advance of the entity using a "Mystic Firebreak". He has also been on the losing side of drawn out battles with the Spectre, as evidenced in the Day of Vengeance limited series.
Helmet of Nabu
The helmet that Doctor Fate wears is the focus of the Doctor Fate identity. It originally housed Nabu's spirit and allowed him to possess the current host, it later only allowed him to advise the host instead. The helmet is what provides the link to Nabu and by not wearing it, as Kent Nelson did at one time, Doctor Fate loses much of its power and knowledge.
Putting on the helmet usually results in its wearer being clad in the other raiments of Doctor Fate, unless the one with the actual claim to the helmet wants to prevent it. On several occasions, villains seeking the power of Doctor Fate have stolen the helmet, in which case the result has typically been that the thief goes insane when he or she puts the helmet on.
At one time a half-face version of the helm was created when Kent felt the Nabu entity had become too dominant.[citation needed]
Amulet of Anubis
The circular device that adorns the livery collar worn around Doctor Fate's chest and shoulders is the Amulet of Anubis, which gives anyone who wears it vast magical abilities. The amulet has also been shown to house the souls of many who have worn the vestments of Fate.[citation needed] In JSA,[volume & issue needed] the amulet contained the image of a farmhouse with the souls of Kent and Inza Nelson, Eric and Linda Strauss, Jared Stevens and Kid Eternity inhabiting it. This dimension was used more than once as a refuge for the JSA to regroup in battle or access the advice of previous Doctor Fates.[citation needed] The villain Mordru was imprisoned in this dimension for some time.
