Crisis On Infinite Earths, Part 3: What Does The Ending Really Mean?

2. The Whole Multiverse Has Been Wiped Out

'Crisis On Infinite Earths, Part Three' consistently kept us up to date with the progress of the antimatter wave. An episode that kicked off with the destruction of Earth-203's New Gotham (and Helena Kyle), we soon discovered that there were only seven earths remaining in the multiverse. And before long, one was left standing: Earth-1.

Earth-90 Barry Allen's sacrifice destroyed the source of the wave and saved the final earth from being consumed by it, but upon the emergence of the Anti-Monitor, the wave resumed and wiped it from existence. And with that, it wiped out the Waverider and all of the heroes on it - with the exception of the Seven Paragons.

The multiverse is no more and all that remains in the Antimatter Universe.
