After Byrne's departure Doom continued to be a major villain in Fantastic Four, and as the 1980s continued Doom appeared in other comics such as Punisher, The Spectacular Spider-Man, and Excalibur. Under Fantastic Four writer Steven Englehart, Doom became exiled from Latveria by his heir Kristoff, who was brainwashed into thinking he was Victor von Doom. Doom would spend most of his time in exile planning his return, but Englehart left the title before he could resolve the storyline. This storyline ultimately ended with the controversial Fantastic Four #350, where writer Walt Simonson had the Victor von Doom who had been seen in the book during the Englehart run being revealed to be a robotic imposter and the real von Doom, in a newly redesigned armor, returning to claim his country from his usurper. According to Simonson's retcon, the last appearance of the real Victor von Doom was in the "Battle of the Baxter Building" story arc, but Simonson's interpretation of the character was unaware of certain major changes at the time to the Fantastic Four. Later writers ignored Simonson's choices, retconning these story elements as an attempt by Doom to blame his own past failures on unruly robots.
