Operation Impending Doom III

"Operation Impending Doom III? Must've heard of that. It's a crucial thing that it's much more bloodier and nightmarish than you think. So, since the Irken Empire did the two Operation Impending Dooms alone, they are now with the pesky Chinese, Vietnamese, North Japanese and North Koreans to do the same thing as what they do."

--Su Ji-Hoon, Operation Impending Doom III

Operation Impending Doom III is the Irkens' third attempt to take over the universe (mainly planet Earth) due that they are now allies with the People's Democratic Union of Asia (China, Vietnam, North Japan, and North Korea). Of course, because of this Zim was excluded and is not allowed to be an invader, ensuring he wouldn't ruin things the third time around. So far, however, the Grand Alliance has still managed to make things more difficult for the Armada (most notably by hijacking the Massive in "Tears of Pain," and leaving a hijacked Stellosphere to fly wildly through space and destroy many Irken vessels in "Battle for the Stellosphere"). Despite this, plans for Irken planetary conquest seem to be going pretty smoothly, with two regions confirmed as conquered, and three others likely to be conquered (as suggested in "Operation White Panther").

There would have been a chapter called "With Our Troops En Masse" in which Operation Impending Doom II was put on temporary hold due to Invader Tenn being captured once agan in Hohhot, Inner Mongolia (thanks to the insane SIR units sent to her in Against All Odds by a Hun soldier). All the other Invaders, excluding Zir and Tak (though Skoodge fields Zir and Tak the information on Tenn's capture), would have been ordered to attempt a rescue by the Almighty Tallest. It can be assumed that afterwards, the Invaders would have gone back to their assigned planets to continue the operation, but soon after the Great Nuclear Exchange, the operation would have been permanently called off because the Irken soldiers listened to Zim that the path of hatred is on its way, after the Organic Sweep merely wiped out the Earth, and thus electrocuting Almighty Tallest Red and Almighty Tallest Purple into death, after shooting Type 451 Laser Rifles at Dib Membrane, because the Irken soldiers never wanted to listen to them.

Operation Impending Doom III is the continuation of Operation Impending Doom and Operation Impending Doom II, which Zim completely ruined both. In Operation Impending Doom III, Invaders (specially picked Irkens) must go to a marked for conquest planet and blend in with the natives, assessing the weaknesses and strengths of the inhabitants.
