Dr. Victor Werner von Doom, better known simply as Doctor Doom, is one of the main antagonists of the Marvel Universe, specifically serving as the main antagonist of the Fantastic Four franchise and one of the main antagonists of the Avengers franchise.

He is the tyrannical ruler of the technologically-advanced European country known as Latveria, and so believes himself destined to prominently seek and expand his rule to the rest of Earth as well as the entire universe, as he believes it is the only way for them to survive.

Dr. Victor Von Doom is the arch-enemy of the Fantastic Four, and is the self-proclaimed unquestioned smartest man on Earth. Doom was born in a Romani family in the nation of Latveria, as the son of a witch and a herbalist. When his mother Cynthia was killed by demons (which she herself summoned to fight Latverian soldiers), he promised revenge, and the death of his father because of a Latverian tyrant only fueled his desire.

Doom began to master both magic and technology, and when his fame reached the United States, he gained the opportunity to study in America. There he met Reed Richards, one of the few men on the planet whose intelligence can even approach his own (and then not by much). Wishing to resurrect his dead mother, he attempted to construct a portal to hell; however, due to miscalculations that Richard Richards warned him about and he refused to acknowledge, the device exploded and damaged his face. Though Doom was responsible for the incident, he still blamed Richards for the accident, considering that to admit his own culpability would mean acknowledging Richards' superior intelligence, and withdrew from society for some time.

He then joined a mysterious order which taught him secret knowledge, including metallurgy. He used it to create a suit of power armor that he has been using (with some modifications) since that day. Unfortunately, in Doom's haste, he had put on the armor's mask before it had adequately cooled and his face was severely burned, an incident which Doom blamed Richards yet again for despite it being clearly Doom's own fault.

From that moment, and forevermore, he has been known as Doctor Doom. He overthrew the previous ruler of Latveria and claimed it as his own, becoming the new ruler of his country. Quickly his path crossed with the Fantastic Four, who became his sworn enemies. However, he has also fought with almost every mega-hero in the Marvel Universe, and even some heroes outside of the Marvel Universe (example: Superman).

On that account, he has had more than a few serious setbacks such as when Reed Richards caused him to be deposed in favor of Prince Zorba. However, he eventually regained the throne with the help of Richards and his compatriots when he showed them that Zorba was laying waste to Latveria in his murderous madness. True, in their eyes they were participating in his retaking of the throne entirely for the sake of the oppressed people of Latveria, and that was good enough for him.

Unlike many other villains, Doom does not want to rule the world out of greed or hunger for power. Doom genuinely believes he should rule the world in order to shield it from the various possible futures he has seen thanks to his ability to travel through time. Thanks to these motives, Doom has, on several occasions, joined forces with heroes, even becoming part of the Fantastic Four's Future Foundation despite them being his archenemies in order to protect the world from bigger threats.

Doctor Doom wears a full suit of armor and a mask, typically silver, to hide his scarred face, often with a green cloak draped over his shoulders and a tunic underneath, giving him the appearance of a knight. His attire also features a large belt around his waist, and his bright eyes are sometimes visible through the mask's eyeholes.

(Victor von Doom) has a complex personality defined by towering megalomania, unyielding pride, a strict personal code of honor, and a deep-seated God complex. He sees himself not as a villain, but as the ultimate savior and rightful ruler of humanity.
