This character commands the Fellowship of the Black Mass, a Satanic cult operating from a church near Boston. He orchestrates a ritual to sacrifice Dolores as a bride to Satan. During the ceremony, Dracula impersonates Satan and abducts Dolores. The cult initially mistakes Dracula for their dark lord until Satan orders them to exact vengeance against Dracula for the deception.

Following Satan’s directive, the character aids efforts to undermine Dracula. In the climactic confrontation, he fires at Dracula but misses when his target transforms into mist. The bullet instead strikes and kills Janus, the infant son of Dracula and Dolores. As a direct consequence of this fatal error, Dracula crushes the character’s skull, killing him.

No background, motivations beyond serving Satan, or development outside these events exists for this character. The name "Anton Lupeski" from Marvel Comics lore does not apply to him within this narrative.
