Death is a common boss in the Castlevania video games, so it wasn’t super surprising that we see him show up in the TV show that Netflix made.
But at first we don’t realize that he’s around at all, as he’s masquerading as a weird vampire from London, England named Varney.
His ultimate goal is to resurrect Dracula himself so that the vampire king can continue slaughtering countless innocents so he can “feed” off of it.
He’s not technically the grim reaper but a creature of darkness that feeds upon death itself. Death and Trevor Belmont have a pretty cool epic fight in which Death loses.
