Zero Hour DC: the key issues to collect

Zero Hour: Crisis in Time (1994) is one of the most ambitious DC crossovers of the decade, and one of the least understood by collectors who know only the title. Published in September 1994, this five-issue event (numbered in reverse from #4 to #0) redefined DC continuity after the editorial traumas of Crisis on Infinite Earths (1985–1986), Knightfall (1993), and Emerald Twilight (1994). It erased entire swathes of the timeline, killed historic characters, introduced new origins, and triggered a wave of #0 issues for almost every DC series of the era.

For a collector, Zero Hour presents a particular profile: the five main issues are affordable and easily found, but targeted tie-ins hide real key issues only connoisseurs know to spot. This guide gives you the issues to prioritize, their current value, and the context to understand why this event remains important in DC continuity.

The context: between Knightfall, Emerald Twilight, and the origins crisis

To understand Zero Hour, you need to place the DCU in 1994. Knightfall (1993) had just broken Batman's back and introduced Jean-Paul Valley (Azrael) as temporary replacement. Emerald Twilight (Green Lantern #48–50, early 1994) had turned Hal Jordan into a supervillain after the destruction of Coast City by Mongul, making Kyle Rayner the new Green Lantern. These two events had deeply divided the fandom.

In this context, DC entrusted Dan Jurgens (writer) and Jerry Ordway (artist) with the mission of cleaning up continuity inconsistencies inherited from Crisis on Infinite Earths. Nine years after the great crisis, massive contradictions had piled up, notably around the Legion of Super-Heroes and several character origins. Zero Hour was meant to start fresh, with mixed results — but considerable editorial impact.

The event's big bad is Parallax, aka Hal Jordan, who wants to literally rewrite time to resurrect Coast City and fix the world his way. He confronts DC heroes in a cosmic battle culminating in the erasure and partial recreation of the timeline — hence the wave of #0 issues that followed the event in October 1994.

The 5 main issues: from #4 to #0

The main Zero Hour: Crisis in Time series is published in five issues, intentionally numbered in reverse. This decreasing numbering is a strong editorial decision symbolizing the countdown to timeline annihilation. Each issue was published two weeks apart.

• Zero Hour #4: The first issue published, introducing Parallax's threat and the first temporal fractures. Hal Jordan appears as Parallax in his most powerful version. Decent reading condition, little speculative value.
• Zero Hour #3: DC heroes start gathering to face the temporal crisis. The event begins touching major editorial lines. Legionnaires from the future appear in a fragmented chronology.
• Zero Hour #2: Power rises. Historic characters start disappearing from continuity. Oliver Queen (original Green Arrow) is killed in this issue — a strong event moment that matters for continuity.
• Zero Hour #1: The final confrontation approaches. Remaining heroes try to contain the temporal chaos. Key issue for narrative understanding, no particular speculative value.
• Zero Hour #0: The event's final issue. The resolution: Hal Jordan is neutralized by Damage (whose explosion recreates the DC universe's Big Bang). It's the most in-demand main-series issue, still modestly so, but the one to keep.

Essential tie-ins: the issues not to miss

The real Zero Hour key issues live in the tie-ins. DC published dozens of crossover issues during the event, but only a few have real value for the collector. Here's the priority selection:

Green Lantern #0 (1994), Kyle Rayner in definitive costume

This #0 issue published right after Zero Hour is the first to show Kyle Rayner in his definitive Green Lantern costume. Previous issues had shown him getting his footing, but here his visual identity is set. For any collector following the character, it's an essential key issue. Current value: $17–$44 in NM.

The Flash #0 (1994), Wally West, first new origin

The Flash #0 issue tells Wally West's new origin as reformatted by Zero Hour. Wally is presented as the definitive Flash, with emphasis on his emotional bond to Barry Allen. This issue is an excellent entry point for Mark Waid Flash run collectors, and remains affordable.

Batman #511 and Detective Comics #678 (1994)

These two issues are part of the Zero Hour crossover on the Batman side and show Bruce Wayne — not Jean-Paul Valley — gradually reclaiming his identity. In post-Knightfall continuity, these issues have narrative importance. They remain very accessible ($11 each).

Hawkman #0 (1994), Total character reboot

Zero Hour served as a pretext for DC to resolve the unsolvable confusion around Hawkman's continuity. This #0 issue entirely reboots the character, erasing decades of contradictions. It's a key issue for understanding why Hawkman had so much trouble finding a stable direction in the 1990s and 2000s.

Green Arrow #0 (1994) and Catwoman #14 (1994)

Green Arrow #0 follows Oliver Queen's death in Zero Hour #2 and introduces Connor Hawke, his son, who will take up the mantle. It's technically Connor Hawke's first full appearance as Green Arrow — a modest but real key issue. Catwoman #14 contains continuity changes affecting the character's history and remains a good tie-in to have.

First appearances created during the event

Zero Hour isn't the crossover generating the most clear-cut first appearances, but the event still produced several key issues in this register, often in the #0 issues that followed.

Damage #1 (1994), the character who recreates the universe

Grant Emerson / Damage is the character created specifically for Zero Hour. His power is to accumulate and release energy explosively, and it's literally his explosion that recreates the DC universe's Big Bang at the end of Zero Hour #0. Damage #1 (his first appearance) is technically the most direct first-appearance key issue tied to the event. The series ran 20 issues before being canceled in 1996. Current Damage #1 value: $5–$17.

Legion of Super-Heroes, complete reboot

Zero Hour served to entirely reboot the Legion of Super-Heroes, whose continuity had become incomprehensible. The #0 issues of Legion series (Legionnaires #0, Legion of Super-Heroes #0) mark a new era for the Legionnaires. For Legion collectors, these issues are important key issues because they mark the start of a fresh continuity.

Fate #0 (1994), the new Doctor Fate

Zero Hour causes the disappearance of the classic Doctor Fate and introduces Jared Stevens, a new character who recovers Fate's artifacts. Fate #0 is this new Fate's first appearance — a controversial character, but whose #0 issue remains a minor event key issue.

Current prices and investment potential

Let's be honest: Zero Hour isn't an event collected for speculative reasons in 2026. The main issues remain very affordable and are unlikely to see significant short-term rises. However, some tie-ins deserve attention:

Zero Hour in DC continuity: long-term consequences

Zero Hour's impact on DC continuity proved more limited than announced. Unlike Crisis on Infinite Earths, which radically simplified the multiverse, Zero Hour only partially resolved the contradictions it aimed to correct. Several characters whose continuity had been "fixed," notably Hawkman and the Legion, experienced new confusion in subsequent years.

That said, Zero Hour had lasting consequences on two characters in particular. Hal Jordan / Parallax remains in this supervillain state until his heroic sacrifice in Final Night (1996), where he revives the Sun at the cost of his own life. His complete rehabilitation only comes in Green Lantern: Rebirth (2004–2005) by Geoff Johns — ten years after Zero Hour. For any collector following Hal Jordan's arc over this decade, Zero Hour is an essential chapter.

The second major impact concerns Connor Hawke / Green Arrow, whose introduction in post-Zero Hour continuity allowed the Green Arrow series to continue after Oliver Queen's death. Connor was then regularly used until Ollie's return in Quiver (Kevin Smith, 2001).

How to organize your Zero Hour collection

The best approach for a collector wanting to tackle Zero Hour is to distinguish three levels:

• Level 1 — the main run: The 5 issues of Zero Hour: Crisis in Time (#4 to #0). Easy to find, cheap. Read to understand the event.
• Level 2 — essential tie-ins: Green Lantern #0, The Flash #0, Green Arrow #0. These are the issues with narrative value AND slight collection value.
• Level 3 — the #0 issues of your favorite series: DC published a #0 for practically every ongoing series in October 1994. If you collect Batman, Superman, Wonder Woman, or another DC series, the #0 issues of these series are directly tied to Zero Hour and deserve their place in your collection.
