Wolfenstein 3D
Although id Software did not develop another "Wolfenstein" game, as their development focus shifted to "Doom" shortly after release, and has never returned to the series, multiple "Wolfenstein" titles have been produced by other companies, sometimes using game engines developed by id. The first of these newer "Wolfenstein" games was "Return to Castle Wolfenstein" in 2001, a reboot of the series, and the latest is the 2017 "".
Cyberdemon
In the action role-playing game "Doom RPG", the Cyberdemon is created by an occultist scientist Kronos. In "Wolfenstein RPG", the Cyberdemon appears as the Harbinger of Doom, summoned by the Nazis at Castle Wolfenstein during World War II. American commando William "B.J." Blazkowicz defeats it using the Spear of Destiny, destroying its right leg and left arm, and the Harbinger vows that it would have a rematch with Blazkowicz's descendent in the future, which happens when Stan Blazkowicz faces it in "Doom II RPG".
