Deacon Joseph Blackfire has lived for far more years than any man should live. He was born centuries ago to a Hotethk Native American tribe under a blood red moon. It was seen as a sign that he would amount to become a leader of men. Blackfire became that leader time and time again, always gaining control, always to eventually lose it. Each time he lost the power, it was to the fabled King of Beasts. One century it was the man known as Walks-With-Mountain Lions. Another it was a great American hunter known as Hugo Wayne. In the 20th Century it was a vigilante known as the Batman.
Blackfire was determined to change things for the 21st Century. No longer would the power be stolen from him. Blackfire was resurrected in the 21st Century by technologies foul and unusual, futuristic yet also ancient. Devices unknown to him, buried deep beneath Gotham, worked on his body and on his soul and brought him back more powerful than before. He sought out the creator of these wonders and found the terrible Darkseid. Somehow he persuaded the god of Apokolips that his skills of manipulation and persuasion were better than Glorious Godfrey's, and that with Blackfire in his power, Darkseid could finally launch a successful invasion of Earth.
The ancient gate beneath Gotham was activated by the belief in Darkseid and in anti-life, channelled through Blackfire's soured soul. Darkseid stepped through the gate, not knowing that Blackfire was not only channelling this belief, but taking it for himself. At least half of the justifiers in Gotham are as fanatical about Blackfire as they are about Darkseid.
Blackfire stands, arms apart and legs astride the entrance to the gate. He looks like Da Vinci's diagram of a man, except his skin is charred, the Apokoliptian power coursing through his veins. He forces a smile on his face as the blue lightning runs through his body, and he finally steps free. "I am become a god, and even Darkseid will kneel before me."
The gate hums and shuts down like an old computer. The way back to Apokolips is closed.
The chant of anti-life on the surface, not that far above Blackfire's head, permeates the air. The heroes and villains around the circumference of anti-life only have one chance to disable both Blackfire and Darkseid, and that's to strike now, before the Deacon can use his new godlike ability.
