Doctor Doom
Species: Human
Enemies: Fantastic Four, The Avengers, X-Men, Spider-Man, Doctor Strange, Black Panther
Doctor Doom might very well be the greatest villain in all of Marvel Comics. His origin, however, is a bit mixed. In one instance, he gets his powers from a cosmic entity. But in the original version, most of his abilities come from mysticism and technology he created himself. His armor is of his own design with his mask being permanently forged to his skin. Doom put it on before it had cooled, as he never planned to ever remove it. He is also a genius, allowing him to be a brilliant tactician.
This comes in handy, as Doom has to be able to plan for every potential issue that could arise. Due to being so familiar with both magic and science, he has beautifully used both to make him nearly impossible to truly takedown. This has also put him in the crosshairs of cosmic entities. Due to his compelling background, he manages to hold his own quite well. Of course, this is why we included him among the most powerful galactic characters. If you match up well with most, that’s impressive.
