Doom is known for the frequent plot device where in it is revealed that his actions were actually those of a " Doombot ", one of Victor von Doom's many robot doubles, either working on his behalf or as a result of rogue artificial intelligence. The plot element of Doombots is often used to retroactively erase events from Doom's history. This plot device was also used to explain that Kristoff Vernard was actually Doom for a brief time in the comics, believing himself to be the real Doom.
