When New York City cop Jim Corrigan was slain, he was denied entry into the afterlife and was chosen to be the embodiment of God's wrath on Earth. As the Spectre, Corrigan metes out swift divine justice against evildoers dispassionately. But Corrigan's humanity also anchors him to his former life and attachments, which can be a dangerous weakness against the forces of darkness.
