Fatboy Tower was a downtown skyscraper that served as the headquarters of Fatboy Industries and its CEO, Manservant Neville. The tower was cylindrical, and topped with an image of the Fatboy mascot.
Fatboy Tower was the site of Tyler Ford's interview for the position of Manservant Neville's right-hand man, and subsequently much of his work. It was also the location of Manservant Neville's Polyditetrahexamono-Trioctalon, and during the events of "The Doomsday Armageddon Apocalypse", Fatboy Tower served as Neville's headquarters as he attempted to inflict his will upon the world.
