Gaspar Nikolovitch Totoyan was an elder of the Totoyan Family who were entrusted with protecting the Vampire Killer in IDW's Castlevania: The Belmont Legacy comics. The Grandfather of Viktor and Pascha, on the eve of Dracula's resurrection, he returned the Vampire Killer to Christopher Belmont so that he could slay Dracula as his Ancestor, Trevor, had done a century before.
Riding into the woods with Christopher, Deimos & Pashca, he left Viktor to guard Christopher's wife, Illyana, only for the boy to be turned into a vampire protecting her from Dracula. Gaspar then allows Viktor to bite him, so that he can gain a connection with Dracula, allowing them to track him.
Despite his force of will, Gaspar fully turns into a Vampire & is swiftly restrained by Pasha & Christopher, who force him to lead the group to Dracula's lair. There, he manages to escape, separating Pascha from the group 7 seemingly being slain by her, only to return during the final battle with Dracula.
Having somehow regained control of himself, he aids Deimos in freeing Illyana, urging them to flee before hurling himself on Pascha's sword, thanking her as he passes on with a smile.
Following the death of Dracula & Pashca's adoption into house Belmont, Gaspar was buried alongside Viktor in the Belmont family cemetery.
