Crisis on Infinite Earths is the original universe-reshaping event, killing Supergirl and the Flash and collapsing DC's multiverse into a single continuity.

Blackest Night is the definitive Green Lantern epic, raising DC's dead as Black Lantern corpses and exploring what it means to live, die, and feel emotion in a universe of colored light.

Identity Crisis is DC's darkest, most controversial event, using a murder mystery to interrogate what heroes are willing to do to protect their loved ones.

Zero Hour attempted to fix DC continuity problems after Crisis, with Hal Jordan as Parallax threatening to rewrite time itself.
