Last Hour to Doomsday.
Cobra demands the U.S. to submit or they will use a giant vortex to destroy the East Coast of the United States. Flint and Lady Jaye decide to take on this mission to stop them in order to prove the Joes that the two lovers can work effectively as a team and save the day. Note: This particular episode seems to have been written and produced before the " Arise, Serpentor, Arise!" mini-series; in fact, it appears to be a leftover Season 1 Episode! The emphasis is on classic characters Flint, Lady Jaye, Destro, the Baroness, and Cobra Commander; the Joes are using Dragonfly helicopters instead of the newer Tomahawks; Cobra is using Rattlers instead of the newer Night Ravens; Firebats are colored silver instead of the red from Season 2; Cobra Soldiers are the Cobra infantry troopers instead of Vipers; and Cobra Commander appears to still be in charge of Cobra. There is no mention whatsoever of Serpentor, and Destro and Baroness report to the Commander throughout the entire episode.
