When Franklin Richards was kidnapped by Onslaught, Doom joined the Fantastic Four, Avengers and the X-Men to battle Onslaught in Central Park. An enraged Hulk was able to crack open Onslaught's shell. However, Onslaught remained as pure psionic energy, separated the Hulk and Banner, planning to spread across the planet. Thor Odinson plunged into Onslaught, trying to contain him. The Fantastic Four, the majority of the Avengers, and the Hulk-less Banner followed in short order, with Doom being forced to join the sacrifice when Iron Man tackled the villain into the energy mass. Thanks to this sacrifice, the X-Men finally managed to destroy Onslaught. Doom, the Fantastic Four, and the Avengers and Banner were believed dead but were instead saved by Franklin, who created a pocket dimension called Counter-Earth to keep them safe. After several months away, the missing heroes returned from Counter-Earth, except for Doom, who remained there for a time. Doom uncovers the secret power at the heart of the planet, an avatar of his arch-foe Reed Richards' son, Franklin, the super-powered youth who conjured this globe and left a bit of himself behind to guide it from within. Doom managed to convince the little boy to relinquish control of this world with little more than a few errant promises of a better life.
