Kirby further described Doom as being "paranoid", wrecked by his twisted face and wanting the whole world to be like him. Kirby went on to say that "Doom is an evil person, but he's not always been evil. He was [respected]…but through a flaw in his own character, he was a perfectionist." At one point in the 1970s, Kirby drew his interpretation of what Doom would look like under the mask, giving Doom only "a tiny scar on his cheek". Due to this slight imperfection, Doom hides his face not from the world, but from himself. To Kirby, this is the motivation for Doom's vengeance against the world; because others are superior due to this slight scar, Doom wants to elevate himself above them. Stan Lee's writing typically showed Doom's arrogance as his constant downfall, and how his pride leads to von Doom's disfigurement at the hands of his own machine, and to the failures of many of his schemes.
