In the Mark Millar penned Fantastic Four 566–569, Doom received a significant power upgrade. He was thrown back in time (perhaps about 50 million years) by the Marquis of Death. Doom then fought through time and space to get back to the present to seek revenge on the Marquis of Death. Doom stated, as he killed the Marquis, he had rebuilt every molecule of his being and increased his power all to destroy the Marquis. In later issues, this seems to have been ignored, however, with writers treating Doctor Doom the way they have always before in terms of power, the arc later retroactively being said to have been a dream had by Valeria von Doom. Doom later joins the supervillain group known as the Intelligencia, but is betrayed when they captured him to complete their plan. With the help of Bruce Banner, he escapes and returns to Latveria. He appears to have been damaged by this experience.
