Fantastic Four Vol.1 #84
While flying over the Balkans en route to the United States, the FF's aircraft is intercepted by SHIELD fighter jets! But not to worry, it's just Nick Fury and Dum Dum Dugan seeking help from the Fantastic Four! Apparently SHIELD has discovered the presence of a large robot army somewhere in Central Europe! What country in the region would be capable of building such an army? Of course there is only one…Latveria! And as shown on the classic cover; Reed, Ben, Johnny, and Crystal enter Latveria and search for Doctor Doom! Wow, is that a good idea? The FF may live (or not live) to regret it!
