DC Comics has built up one of the strongest legacies in comics through a combination of serialized storytelling and epic sagas. Since 1986's Crisis on Infinite Earths (by Marv Wolfman & George Pérez), the company has come to embrace the event format as their go-to way to tell big and transformative stories. It's no secret that the event format has come to include stories that, in years gone by, would have been limited to a single story arc.
