The year is 1984. Mattel teams up with Marvel to create a line of officially-licensed action figures based on Marvel characters. Someone decides that the best way to promote these toys is to create a 12-issue comic book series that includes all of the characters, and the now-classic Secret Wars is born.

Back in 1984, big crossover events didn’t really happen, so the thought of pitting Marvel’s best superheroes against it’s best villains was a fairly groundbreaking concept.
So how exactly did they bring all of these characters together?
