Zero Hour: Crisis in Time!

Lore & Background

As Parallax begins his rewind, the universe doesn't just glitch; it screams. Time fractures into jagged shards, causing heroes from different eras to collide or vanish entirely. The original Justice Society of America flickers in and out of existence; historical figures find their identities rewritten before their eyes. The Spectre, usually the ultimate arbiter of cosmic justice, finds himself powerless against Jordan's reality-warping grief. History becomes fluid—births are un-born, deaths are undone, and timelines bleed into one another like watercolors in rain. Reality stabilizes only through a brutal cost: the sacrifice of key figures and the intervention of the last surviving Guardians. The resulting timeline is cleaner, but it bears the scars of its own reconstruction.

In Their Own Story

The sky above Metropolis does not just darken; it flickers like a dying bulb. One moment, Superman stands on the Daily Planet roof, the sun warm against his cape; the next, he is standing in a grey void where the city never existed. He sees stars being born and dying in the span of a heartbeat. Then comes the scream that tears through the dimensions—not of pain, but of absolute, crushing grief amplified by cosmic power. Above him, a figure made of burning yellow light descends, his eyes hollow pits of regret. 'I can fix it,' the voice echoes, sounding like Hal Jordan yet echoing with the weight of a thousand dead worlds. 'I just need to go back. Just one more time.' The ground beneath Superman's boots turns into sand, then water, then nothingness. Time is not flowing; it is breaking apart, and the man who was once Earth's greatest protector is holding the hammer that will shatter history forever.

Reader's Guide

The saga spans five core issues (Zero Hour #0–#4) plus extensive tie-ins that ripple across every major title. It begins with the shocking revelation: Hal Jordan has murdered the Guardians and decimated the Green Lantern Corps on Oa. As Parallax initiates his time collapse, history itself becomes unstable. Booster Gold, uniquely retaining memories of the original timeline, partners with a resurrected Hourman (Rick Tyler) to hunt him down. They are joined by heroes like Superman, Batman, and Wonder Woman, who witness their own origins shifting around them. The climax sees Parallax confronted at "Zero Hour"—the moment before creation—where he is defeated not just by force, but by the refusal of the universe to be rewritten. In the aftermath, the Green Lantern Corps remains extinct until Kyle Rayner is chosen as the last lantern, and the DC Universe enters a streamlined new age with updated origins for many icons.

Did You Know?

• Continuity Cleanup: The event was explicitly designed to fix plot holes accumulated since Crisis on Infinite Earths, effectively rebooting character ages and timelines without erasing history entirely.
• The Anchor: Booster Gold serves as the audience's guide; he is one of the few characters who remembers the "old" timeline, grounding readers in the chaos.
• Lantern Legacy: The genocide of the Green Lantern Corps was so severe that Kyle Rayner became the sole survivor for years, revitalizing the franchise with a new, human-centric take on the ring's power.
• The Name: Zero Hour marks the theoretical instant Parallax aims to reach—the point where time resets to zero, erasing all of history to start anew.
