Blood for the Baron!

Wrong. Even though they were the most featured in the comics (I guess; I haven't read much of Hama's work), they just appeared in animated form in "Shadow of a Doubt" and "The Sword". Seemingly the DiC people were more inclined to the sub-teams with "message".

EDC

Wrong. They just appeared in the two-parter "The Greatest Evil", mainly because, to give better the "drugs kill" message, Headman was killed by an overdose he tried to use agains both the Joes and (well, if that didn't kill him, his own base crumbling on him did), so the EDC ended without any enemy to fight and they didn't appear again in the DiC series.
Now, I'm sure the next answer will be the right one

Slaughter's Marauders

hmmm... no, they weren't even one of the options I gave, and they just appeared in "Operation Dragonfire".

I guess I'll have to make a new question.
During the Marvel run, when infiltrated , who were the two members who distrusted her?

Eco Warriors

tomax and xamot?

Slice and Dice also Zarana didn't either

The right answer is Slice and Zarana. As far as I noted, Dice didn't give a damn. In fact, that same saga made me know and love Slice (in a straight sense), and that's why I don't have the frequent confusion between both ninjas that even the creative teams had sometimes (they were name-swapped in the DiC episode "The Sword", to give an example).

Sorry Sundance. I had already changed the question when you answered Eco Warriors and, now that you mention that, where were the Crimson twins during that saga?
Don't answer that. I don't know the answer and, besides, it's Ironblood's turn.

The twins had pretty much left Cobra after the Battle of Benzheen. Name the last strikes the Red Shadows performed which led to Resolution Nine-Zero-Nine being activated as depicted in World Enemy No.1.

s struck a bullet train in Central Japan, an oil rig in the Java sea, and a Concorde aircraft in the Middle East and took everyone hostage. demanded over 200 billion pounds sterling for the hostages but, depite being paid, he ordered the s to suicide-bomb themselves along the hostages. At the same time, some s tried to kill a counter-terrorism council that had been assembled due to the hostage situation. Those were stopped by and , and the council, having been close to death themselves decided to remove the once for all.
