Ko-Achter

Big bad voodoo daddy.

Employed Chuck Hondo as his "Midnight," a terrorist during the Civil War in the Weird West. Then employed/manipulated his sister, Jessica, in a similar way to murder Chuck.

Jessica soon overpowered him and stole all his power, replacing him as the dominant evil power in the Weird West.

He teamed up with the Infiniteers to track Jessica down, eventually--and predictably--turning on them to recapture his own powers. In the ensuing battle, he died when Thayne snap-bladed him in the face.

Other appearances
Ko-Achter appeared as younger version of himself in Vampire the Masquerade, a blood vendor for Kirin and Hondo.
