In 2005 and 2006, Doom was featured in his own limited series entitled Books of Doom, a retelling of the origin story by Ed Brubaker. In an interview, Brubaker said the series was a way to elaborate on the earlier portions of Doom's life which had not been seen often in the comics. The series also set out to determine if Doctor Doom's path from troubled child to dictator was fated or if Doom's own faults led to his corruption — in essence, a nature versus nurture question; whether Doom could ever become a hero. Brubaker's version of Doom was heavily influenced by the original Lee/Kirby version; responding to a question if he would ever show Doom's face, Brubaker stated "[F]ollowing Kirby's example, I think it's better not to show it."
