So, Iron Man makes a new enemy in the Titanium Man. Behind the arm of this tin man is just another fat communist who's jealous of our boy Tony Stark. However, this particular fat communist decides to write Stark a letter about it. Basically, he challenges Iron Man to a duel. Iron Man accepts, but the victor won't be revealed until next issue. It doesn't look great for Iron Man, but hey, it's just a cliffhanger. Don't sweat it.
In Cap's world, a mad scientist prepares a means of eliminating him and Bucky. Bucky is captured as bait, and Cap heads off to rescue his partner. Smells like cliffhanger as well.
Why does a mad scientist's henchman always have to look like the Hunchback of Notre Dame?
