Blackest Night
During the Blackest Night, as the Black Lantern Corps rampages through Gotham City, Scarecrow wanders through the streets, wanting to feel the terror the Black Lanterns are causing the citizens, but revealing that overexposure to his fear gas has left him emotionally dead, unable to feel fear, courage, or any of the other five emotions on the Emotional Spectrum, except when facing Batman. When Ganthet causes the rings of the Seven Lanterns on Earth to duplicate and deputize others on Earth, the Qwardian ring selects Crane, inducting him into the Sinestro Corps. Overjoyed at being able to feel fear again, Scarecrow eagerly joins the battle against the Black Lanterns. However, Lex Luthor, who had received the other Orange Lantern Ring, is overwhelmed by the orange light of avarice and takes Crane's ring.
