In the history you know Cobra, a ruthless terrorist organization determined to conquer the world, is regularly thwarted in their attempts by the heroic efforts of G.I. Joe. But on another Earth, a minor mishap with the Mass Device leads to Cobra developing the capability of interdimensional travel. Not only that but they also discover another world, a primitive one nonetheless rich in resources and potent artifacts. Rather than continue to futilely butt heads with the Joes, Cobra opts to lay low on their Earth and concentrate on attempting to conquer and plunder the world they discovered first. The Commander believes once they have total control over its people and treasures, it should be child's play to use their increased might to then successfully take over their own world.
After some preliminary scouting they establish bases in isolated backwaters among the various regions of the world. Once those have been established they will begin more overt and active campaigns and schemes to conquer various parts of the planet. Besides their regular forces, this version of Cobra enjoys the use of all their more exotic technological achievements such as The Mass Device and The Weather Dominator. They begin with no native allies but are free to recruit/buy/blackmail/mind control any they can. Including the gods themselves if they're feeling ambitious.
So, can Cobra conquer a magical but primitive world with their technological superiority? Or will its nations, organizations and heroes prove too much for them in the end? I, The Watcher, pose this question to you all...
