Earth-689
The Avengers (Earth-616) brought Doom's Time Machine and their alternate counterparts back to Doom's stateside castle in order to repair the device and return history back to normal. As the Scarlet Centurion appeared to reveal the whole ordeal was actually orchestrated by him to take over the Earth-689, Goliath shrank down to Ant-Man size and activated the time machine, sending the Centurion into the far future, and the Avengers back to their own version of history. The Watcher appeared and explained to the leader that the Scarlet Centurion was formally known as the time traveler Rama Tut, and after his meeting with Dr. Doom became the Centurion. Having defeated the Centurion, the Avengers sent him to the year 4,000, where he would become Kang the Conqueror.

Castle Doomstadt is besieged by Zombified Super-Heroes (despite being defended by a magical force-field), as it is the last remaining location on Earth which has any uninfected Humans.
