A basic review of the series. Here we go.
What If (Vol. 0?)
#1 (Jun 1966): Iron Man's origins are tampered with by communists,
who implant him with a radio-transmitting device that can cause pain
and stop his heart if he disobeys. Nick Fury somehow figures it out on
a hunch right away but can't convince anyone until the Iron Man "trojan
horse" has already disabled the Fantastic Four. Iron Man eventually says
"Fuck it" and disobeys, leading to his heart being stopped, but Mr.
Fantastic, being a swell guy and all, revives him anyway. Tony Stark
can no longer be "Iron Man" but can live a normal life and the villains
("Fu Manchu" ripoffs) get an Iron Man "dummy" fill ed with TNT at their
doorstop. Blah. D+
