How Superman Escaped The Eradicator (Rebirth)
The Eradicator has this ability to absorb living things and seemingly use them to get stronger. He absorbed Krypto in the previous issue and just recently, Superman as well. But Superman didn’t go out without a fight. Communicating with the other trapped Kryptonian life forces inside the Eradicator, he struck a deal with them which led him to escape. I somehow get the sense that this is the first time the Eradicator experienced an inmate escaping.
