Doom seemed reappeared in issue six of Ultimate Power, a crossover between the "Ultimate Universe" and the universe of the revamped Squadron Supreme, seemingly intent on taking over the Supremeverse. In issue eight, it is revealed to be simply a Doombot (the first seen in the Ultimate Marvel continuity). Dr. Doom is seemingly later seen in Ultimates 3 as the one controlling Ultron. It is noted however, that, starting in "Frightful" and through his Ultimate Power and Ultimates 3 appearances, his 'goat legs' are not present and he resembles his regular 616 counterpart. As to why his former look has been abandoned is yet to be revealed.
