A new villain, Mr. Doll, emerges with the power to control to cause intense pain to anyone he can mold his doll to resemble -- including Iron Man! One conflict with him leaves Tony so drained that he sees no choice but to build a new, lighter set of armor to relieve the stress on his heart.
While Tony works on his secret project, Mr. Doll sets about stealing the fortunes of richest men in the city, and Tony Stark himself is Doll's next target.
Iron Man manages to defeat Mr. Doll by shaping his doll with a ray into Mr. Doll's own face, then making him drop it.
