Following the death of the New 52 Superman, Luthor creates a new warsuit decorated by Superman's S-shield, deciding he is the new protector of Metropolis. He is confronted by the Pre- Flashpoint version of Superman, who refuses to believe Luthor's intentions are noble. In DC's 2016 line-wide relaunch DC Rebirth, large parts of the New 52 canon are removed (later said to have occurred in a different timeline) while large parts of the Post-Crisis canon are restored to the DC Universe. Eventually, this affects the Superman comics as well, in the wake of the 2017 storyline "Superman Reborn" Luthor's backstory from Superman: Secret Origin and large parts of his Post- Crisis continuity are restored, while the New 52 events are largely removed. The canon says that Luthor still served in the Justice League for a time.
