When Doom endowed the alien Tyros the Terrible with the Power Cosmic and sent him to destroy the Fantastic Four in New York City, he monitored the fight from his cloud-covered Fortress. While Tyros confronted the Human Torch and the Thing, Doom used the ship to capture the Invisible Girl, who was returning to New York in a section of the Fantasti-Car MK II. Doom sent a doppleganger robot to salute the Invisible Girl but, when she was defiant, the robot slapped her, revealing its nature as it was far cruder than Doom. The Girl destroyed the robot, then Doom used a communication sphere to confer with the Girl. Doom mocked her, showing the fight and prompting her to choose between helping her friends or confronting Doom - she of course left. Albeit Tyros held his terrain, Doom saw from his vantage point in the ship that his main nemesis Mr. Fantastic had not arrived. Doom disembarked the Fortress to join the fray and delay Tyros's victory until Fantastic could come. This encounter did not end as he expected, because both Doom and Tyros were apparently destroyed.
