Behind The Scenes

 * James Urbaniak also plays the voice of Dr. Thaddeus S. "Rusty" Venture of the animated show The Venture Bros. Doctor 0's name may be a reference to Dr. Byron Orpheous, a character from the show who is frequently referred to as Dr. O for short.
 * A second reference to the Venture Bros. may come from Doctor O (Zero's) name and the fact that Rusty Venture, try as he might, is never successful in being a super scientist, just like Doctor O.
 * If you have the Wild Wasteland trait active, one of his broadcast messages across the crater asks the lobotomites to please remember to clean the walking eye. This is another reference to the Venture Bros. With Wild Wasteland, these walking eyes also appear in the Magnetohydraulics Complex, although the player cannot interact with them.
