During the "Forever Evil" storyline after Batman uses a yellow ring, Sinestro appears to confront Power Ring. Sinestro follows Power Ring through the sewers, eventually severing his right arm and allowing his ring to go search for a new host. Relieved to be free, Power Ring dies, thanking Sinestro. After that, Sinestro joins Batman, Catwoman and the rest of Lex Luthor's team into taking down the Crime Syndicate. When it comes to the final battle against the Crime Syndicate, Sinestro and Black Adam move the moon where the sun ends up weakening Ultraman. In the aftermath of the battle against the Crime Syndicate, it was stated that the villains who helped to stop the Crime Syndicate would have their criminal records wiped. Sinestro and Black Adam did not care about that; they begin laughing since they know the rules do not apply to them and went their separate ways, along with the other villains.
