The Soul Strangler is apparently of a supernatural nature. It can appear at sites of intense hatred (it has only been seen in the presence of members of the Ku Klux Klan or the Dragon Circle). It rides a horse, and carries a flaming pitchfork and a long noose. It can vanish, to parts unknown, at will. It's vulnerabilities and limitations are unknown.
Pitchfork: The Soul-Strangler's pitchfork can project flames (real fire, or perhaps soul-searing hellfire), or can be thrown at a victim. It apparently returns to the Strangler's hands as needed.
Fear Generation: The Soul-Strangler likely either generates fear and hatred in others, or feeds on the fear and hatred it finds in others. It is also possible that it possesses greater power to harm an individual in the grips of fear.
The nature and history of the Soul Strangler is, for the most part, unknown. In 1867, the original Soul Strangler appeared alongside the Ku Klux Klan in order to enforce its sentence of Caleb Lynne. He duped Lynne into believing him to be a demon, shot him in the shoulder, drug him with a noose, and hung him unto his death as the Klansmen restrained Caleb's wife, Ella.
In the modern era, the spectral Soul Strangler appeared at a KKK rally in Manhattan. He spoke, "Hear me, men of the Invisible Empire, heed the words of your master! I have come in your hour of need to lead you into sacred battle!" The Strangler then revealed the presence of the Black Panther, who had been observing the rally in secret.
