A Dimensional Displacement Device is a device used by Alpha-1 in the 1987 TV series episode "The Foot Soldiers are Revolting". Alpha-1 uses it to fire rays from atop a New York City skyscraper, teleporting people from Earth to the Technodrome on the Volcanic Asteroid. By the end of the episode, Donatello uses it to send Alpha-1 to destination unknown and Bebop and Rocksteady to the Technodrome.[1]
