Heroes in Crisis makes one of the strongest arguments yet for why DC Rebirth needed to happen. This is a story that plays very directly on the long history of DC’s superhuman community and the many friendships and rivalries that have developed over the years. Much like with his Batman run, Tom King writes this story as though all of that history still exists and wasn’t wiped out by Doctor Manhattan’s clinical, all-powerful hand. This issue in particular draws on classics like the original Teen Titans, Justice League International and The Killing Joke as it delves deeper into the many characters impacted by the tragedy at Sanctuary. That long sense of history gives this story the emotional weight it needs as the narrative slowly but surely moves forward.
