Doctor Fate
There are quite a few characters who have taken on the persona of Doctor Fate, ever since the character appeared in 1940. What can be said about each of the versions is that they all possess plenty of superpowers, all of which derive directly from the ancient being Nabu (a member of the very first sentient beings in the universe).
Thus, Doctor Fate can fly, is a very skilled spell caster, has super strength and invulnerably, as well as being a powerful telepath (there are also some other feats, such as fire and lightning manipulation). His magical powers are further enhanced by the Helmet of Fate – which, without Nabu’s assistance, holds tremendous arcane powers. Thus, Fate can raise the dead, warp reality, animate objects, and so on.
So what we have is basically a regular mystical superhero who, when channeling the powers of Nabu, becomes even more powerful. At one time, Fate basically defeated Darkseid, by casting a spell of love on him.
This is hardcore indeed.
