Jim Corrigan is the deceased GCPD detective who hosts the spirit of god's wrath, the Spectre, giving the Spectre guidance.
Jim Corrigan is the original human host of the Spectre. Murdered in life as a police detective, his soul was bonded to God's spirit of divine vengeance. Using his conscience and willpower, he controls the Spectre force and gives it human perspective.
Some point prior to the beginning of Year Three, Corrigan was confronted by Mister Mxyzptlk and was defeated by the fifth dimensional imp, driven insane by a spell to mimic the effects of Joker Toxin, and locked up in Arkham Asylum as its sole remaining patient. Mxyzptlk would then usurp Corrigan's identity of the Spectre and use it to protect Superman from magical users. The new Deadman, Dick Grayson, finds Corrigan in Arkham, and despite his insanity, Jim was able to reveal to him who was truly behind stealing the mantle of the Spectre.
