What was “Acts of Vengeance”?
Doom participated slightly in a crossover series of Marvel Comics call “Acts of Vengeance”, which, if nothing else, caused a lot of Doombots to appear in a lot of Marvel titles. The basic premise was that the evil Norse God, Loki, had developed a scheme to eliminate the do-gooders of Earth by having them fight foes that they had never encountered before. Doom was supposedly one of the six core villains recruited by Loki to serve this scheme. “Doom” appeared regularly in the Avengers, Punisher, and Spectacular Spider-Man at this time, with cameos in several other titles. However, the other core villains discovered that the Doom with whom they had been dealing was merely a Doombot, and not Doctor Doom at all. In the Fantastic Four, Doom uses a Doombot and an army of inept villains to demonstrate the foolishness of the entire Acts of Vengeance.
