History
After killing Terrax the Tamer with his own ax and draining the Silver Surfer of his Power Cosmic before killing him, Red Hulk went on a rampage killing the remaining Defenders and Offenders. After antagonizing Galactus with the corpse of the Silver Surfer, Galactus removed the Power Cosmic from Red Hulk and learned of what transpired. In anger, Galactus decides to destroy Earth as well as the Grandmaster and the Collector as punishment for Silver Surfer's death. The Grandmaster was forced to reverse everything Red Hulk did, causing a new reality to be created, Earth-90512, where the killings of the Defenders and Offenders by Red Hulk were permanent.[1]
