'E'd Edd n Eddy Z: Interdimensional Crisis is a text-based movie written by the maker of the Ed Edd n Eddy Z animated series, SSJ7G. It does derive some of its parts from another work SSJ7G wrote, as well as the Crisis of Multiple Earths Universe 2 what-if. The full story can be found here for now.

However, one day, strange events start to happen, with a being known only as Oskuro searching for aritifacts known as the "Dimensional Stones". With Corey and Sonic immersed in another universe's problems and Oskuro with four of five of the powerful stones, can this darkness be destroyed, or will reality be distorted or destroyed?
