Marvel and DC are already gearing up for this year’s big superhero comics crossover events. The shape of Marvel’s Fear Itself is not yet entirely clear, but it’ll involve a central seven-issue miniseries by Matt Fraction and Stuart Immonen (which launches in April), a seven-issue secondary miniseries called Fear Itself: The Home Front, a Fear Itself Prologue one-shot, and a bunch of tie-ins in ongoing series.
Meanwhile, DC Comics announced on Friday that the five Geoff Johns/Andy Kubert issues of their upcoming crossover Flashpoint, which starts in May, will be accompanied by no fewer than fifteen three-issue tie-in miniseries, as well as a handful of one-shots. It’s also not clear yet whether The Flash or other ongoing series will also tie into Flashpoint, but the story will be unfolding over upwards of fifty individual issues. Is that a lot? Let’s compare the issue counts of other event comics of the recent and not-so-recent past. (Some totals may be approximate.)
