[General Comics] What are the doctors of DC and Marvel ACTUALLY doctors of?

Doctor strange, doctor doom, doctor octopus, doctor Destiny, doctor fate, etc, on and on and on.

Doctor Strange was a surgeon before he became the Sorcerer Supreme.

Doctor Doom has multiple doctorates in physics, biology, and other technical fields.

Doctor Octopus is a physicist.

Doctor Fate (the original, Kent Nelson, at least) was an archaeologist. There have been others who took on the helm of Nabu, some of whom just took the name Fate.

Doctor Destiny seems to be involved in medicine in some way, though exactly what his doctorate was in is unknown.
