We knew that Heroes In Crisis was getting a couple of additional issues, what would originally have been spin-off one-shots by Tom King with other artists, now inserted into the main narrative.
So Heroes In Crisis #3, originally drawn by Clay Mann would have been:
The Man of Steel versus…Booster Gold?! Superman finds out the hard way that Booster can be a formidable opponent when his back's against the wall. Of course, being the prime suspect in a superhero massacre and exposing a secret trauma hospital for metahumans will do just that. Meanwhile, Batman and the Flash combine their detective skills to investigate what went awry at Sanctuary and uncover a serious glitch in the system-not to mention an explosive, spoiler-ific secret! In Shops: Nov 28, 2018 SRP: $3.99
The new solicit, just revealed, with art by Lee Weeks and Clay Mann, now reads;
Tragedies deepen as more secrets behind the "superhero hospital" called Sanctuary are revealed! What compelled Batman, Superman and Wonder Woman to create it in the first place? How was it built? And if the hospital truly is alive via A.I., who – or what – is the brain of "Sanctuary?" Another layer peeled back in the biggest mystery woven through the entire DC Universe.
Look for what was originally planned for #3 to move to #4….
