Deacon Joseph Blackfire is a sinister preacher and a villain in the DC comics, Blackfire is stated as being over 100 years old, and is often portrayed as a power-crazed, manipulative, and charismatic con artist and cult leader skilled in manipulation and brainwashing. Blackfire claimed to be a Native American shaman who was entombed alive after being found guilty of killing a tribal chief and committing heresy.
Deacon Blackfire is a conman and a cult leader who was over 100 years old at the time of his death, despite appearing much younger. He has discovered the secret to eternal youth, bathing in buckets and buckets of human blood. Blackfire craves power and destruction, and orchestrates his 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 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.

The New 52
In The New 52 (a reboot of the DC Comics universe), Deacon Blackfire is an evangelist who is the center of the occult power permeating Arkham Asylum, with Joker's Daughter as his enforcer. When Batwing and The Spectre (as Jim Corrigan) uncover the secret of the Asylum, both are captured by Blackfire and his demonic army. In the same issue, flashbacks are shown of the previous time Batman encountered the Deacon. The Deacon had an army of devoted homeless and underprivileged, but he also kept many of them drugged under his control. He attempted to do the same with Batman, keeping him chained and drugged in his basement for 7 days and 7 nights, but the Dark Knight's resiliency led to Deacon ordering his devotees to kill him. Batman however, brought up the question of why Deacon Blackfire wouldn't kill him himself, if he was as powerful as he wanted his army to believe. Batman is able to break the pipe he is chained to, and in a reversal of their confrontation in "The Cult", orders the Deacon to kill him to prove himself in front of his followers. Deacon Blackfire refuses multiple times, and his disillusioned army turns on him and appears to beat him to death.
Between their first encounter and the time of Eternal, the Deacon has taken over the body of Maxie Zeus, in attempt to regain entry into this world.
