Doom and Richards are probable overall the two smartest human on the planet and two of the smartest beings in the universe. One of their major differences is Doom can use magic and often combine it with his technology. Yet as far as I know Doom always treats them as if they are something different. (Please correct me if I am wrong on this). Richards on the other hand has never been able to wrap his head around it. He always has to go running to Dr. Strange.
What do you think it is about Doom that allows him to use magic, but not Reed?
