Deacon Blackfire AKA Joseph Blackfire is a manipulative and power-hungry cult-leader who affects warped and perverted variations of religious zealotry, and practices brainwashing, occult rituals, and worship of his own being.

In his original appearances within New Earth continuity, it remained ambiguous whether he was truly supernatural or simply a charlatan, whereas later comics in Prime Earth cannon made him to be explicitly magical.


New Earth[]

The Cult[]

Deacon Blackfire was a con-man and cult leader who claimed to be over 100 years old at the time of his death, despite appearing much younger. He had discovered the secret to eternal youth: bathing in buckets of human blood. Blackfire craves power and destruction, and orchestrates his religious movements toward these goals.

During The Cult he forms an army in the sewers beneath Gotham City, largely composed of the homeless and derelict. Blackfire uses this army to begin a violent war on crime, which escalates into him taking over the entire city, resulting in it being isolated from the rest of the country. Blackfire captures and brainwashes Batman, temporarily making the Caped Crusader a member of Blackfire's cult. Batman eventually breaks his conditioning, but its after-effects make it difficult for him to capture Blackfire.

After a brutal search through the sewers with Robin, Batman confronts Blackfire, who demands that Batman will kill him, making him a martyr. Batman refuses, and instead savagely beats Blackfire in front of his army. Blackfire's army turns on him and kills him.

Blackest Night[]

Deacon Blackfire is one of the many villains raised from the dead in Gotham City to join the new Black Lantern Corps as zombies during Blackest Night. Along with Abattoir, KGBeast, Blockbuster, King Snake, Magpie, Ventriloquist and the Trigger Twins he has received a Black Lantern Ring. He has been seen terrorizing the city, and tearing out the hearts of innocents in the churches to feed on their emotions and life force when they are feeling the most compassion.

Prime Earth[]

Batman Eternal[]

Blackfire's soul haunted Arkham Asylum where it tormented the minds of the asylum's inmates. Blackfire's undead soul managed to create a new cult of super-criminals with, "The Joker's Daughter" Duela Dent as his lieutenant and other members including the Scarecrow and Doctor Phosphorus. This cult reincarnated Deacon Blackfire within the host body of fellow super-criminal, Maxie Zeus. This caused the cult to be confronted by occult superhero, "The Spectre" who removed Blackfire from Zeus' body and banished the spirit to Hell.

The Cursing of Gotham City[]

The spirit of Deacon Blackfire attempts to resurrect himself into the body of a kidnapped boy in Detective Comics 982.
