In the mini-series "Mys-Tech Wars" (1993), by Dan Abnett and Bryan Hitch, their forces fought most of the Marvel Universe's assembled heroes. In the resulting demonic invasion, many of Earth's heroes (including a majority of the Avengers, Fantastic Four, and X-Men, Spider-Man, Ghost Rider, and Nick Fury) were slaughtered. However, due to the surviving heroes' efforts, the entire event was erased from history. As such, only a few, such as Doctor Strange, Professor X and Motormouth, actually remember what had happened.
