alternately aired under the title "The MASS Device" during the series' syndication. Cobra develops an experimental teleportation unit, known as the MASS device, which has the ability to transport matter to any global location, using a satellite to relay the teleportation beam. G.I. Joe must stop Cobra by creating a MASS system of their own, but first must gather the three rare elements that power the device, which consist of radioactive crystals, heavy water found in the depths of the ocean, and fragments from a giant meteorite.
