WARNING: The following contains spoilers for DCeased #6 by Tom Taylor, Trevor Hairsine, Stefano Gaudiano, Rain Beredo and Saida Temofonte, in stores now.
The events of DCeased essentially decimated the version of the DC Universe that was introduced in this series. With most of the world consumed by a version of the Anti-Life Equation that spreads like a zombie pathogen, the heroes were desperately fighting not just themselves but many of their closest allies.
While iconic DC heroes like Batman, Superman, Wonder Woman and the Flash all fell victim to the virus, a handful of heroes were still alive by the time the dust settled. Now, here are all of the major heroes who survived DCeased and made it to Earth-2.
JUSTICE FOREVER
Most of the Justice League was wiped out over the course of DCeased, alongside the rest of Earth's population. Superman, Batman, Wonder Woman, Flash, Aquaman, Martian Manhunter and Hal Jordan were all infected at one point or another, and most of them were eventually killed. The same goes for most other superheroes, who were overwhelmed at some point by the sheer waves of infected across the planet. Only a handful actually make it to the arks constructed by Cyborg and Lex Luthor, neither of whom end up among the survivors. The ships are able to save limited amounts of people, but they still insured that humanity would survive to fight another day. There are still a handful of heroes remaining, however, as they were able to hold the line and help protect the remnants of humanity before escaping themselves.
Black Canary is arguably the most powerful of the survivors, maintaining her own powers while also wielding Hal Jordan's Green Lantern ring. Other surviving members of the Justice League include Green Arrow, Mera, Black Lighting, Lighting, Thunder Hawkgirl, and Firestorm. Other potential survivors (who were seen in previous group shots and were never shown being killed or corrupted) include Supergirl, Power Girl, Beast Boy, Wildcat and Red Tornado. Altogether, those survivors could fill out the roster of a small but still-powerful Justice League. The survivors also included three major civllians who regularly play roles in the world of superheroes: Lois Lane, Alfred Pennyworth and Mercy Graves, who survived the destruction of Metropolis alongside Lex Luthor in a Lex-Corp suit.
THE NEW TRINITY
While the chief heroes of the DC Universe all fell in battle, their legacies will live on thanks to their surviving sidekicks. Jon Kent was able to hold his father at bay long enough for the Green Lanterns to arrive at Earth, where their sudden arrival saved the boy's life. Damian Wayne has taken on the mantle of Batman, having been given it as a final parting gift from his father. Cassandra Sandmark, one of DC's Wonder Girls, is one of the only Amazons to escape the fall of Thymiscara, and will likely be seen as a leader by any other Amazon survivors. All three will likely become the next generation of their respective mentors, ensuring the survival of the DC Trinity in at least some shape and form.
It's also worth noting the apparent survival of Wallace West, DC's current Kid Flash. Although he initially volunteered to help bring down Barry Allen once he was infected, Superman kept the young speedster from sacrificing himself against his mentor. Although Superman was able to stop Flash, this directly led to his own infection. Wallace will likely want to make up for that and could become the new Flash on the newly named Earth-2, an alien world which will become the new home of humanity as they try to rebuild.
GIVE IN TO THE GREEN
There are a handful of other survivors as well, although their current status is unknown. John Constantine, Zatanna, and Doctor Fate were revealed to have survived the events of the crisis in the DCeased: Good Day to Die tie-in, before disappearing in a flash of magical light. Constantine even hinted that he fully intends to "save the world.".Although the world has been largely wiped out, two of the most potent and powerful magical figures in the world stand alongside him, and it's unclear what, if anything, they could do to restore any of what was lost.
There's also the revelation that Guy Gardner, alongside the rest of the Green Lantern Corps, were largely unaffected by the spread of the Anti-Life infection. Far away from Earth, Guy was able to avoid all the chaos that unfolded on Earth. It's possible then that the other human Green Lanterns like John Stewart, Kyle Rayner, Simon Baz or Jessica Cruz could have been elsewhere in the galaxy and remain uninfected by the Anti-Life virus. If so, then the surviving humans just got a massive amount of power to back up Dinah Lance.
Two other survivors are shown to have made it through the apocalypse. But Poison Ivy and Harley Quinn elect to remain on Earth instead of using the Arks to escape. Poison Ivy refuses to abandon her connection with the Green, which she has been using the end of the world to seed plant-life across the world. At this point, she's even transformed Gotham into a full-blown jungle, giving her and Harley plenty of space to defend themselves. In fact, it's possible that Ivy could able to spread the Green even further across the planet, using the tendrils produced by her vines to catch and kill the remaining infected. She could turn the unpopulated Earth into the paradise she always wanted and keep Harley Quinn by her side. While DCeased might have ended poorly for just about everyone else in the DC Universe, it may have ended up giving Poison Ivy. exactly what she wanted.
