Isaac (Netflix's Castlevania)

Isaac is a major antagonist in Netflix's cartoon adaptation of Castlevania, loosely based on the character from the video games. He is the misanthropic servant and Devil Forgemaster of Count Dracula, who aid him in his attempted genocide of humanity.

He was voiced by Adetokumboh M'Cormack.

Appearance
Isaac is portrayed as a tall, bald and dark-skinned man, with two scars on the side of his head, in full Devil Forgemaster uniform. To further the contrast with the raging, violent and over-the-top fanatic of the game, he is a very quiet and collected man of a few words, though violent and devoted to Dracula.

Personality
Isaac despises humans, and despises even more being one, resenting them for shunning him and rewarding service with ill-treatments, and flogging himself as a penance of sort. He believes that Dracula will purify the world, and the only way to make him furious is treachery, be it only considered.

History
Isaac used to serve under a master who mistreated him and scorned him for showing devotion, believing that there was no love in the world, prompting Isaac to kill him. He spent years as a slave and learned magic from occultists’ books. He was rescued from bandits by Dracula when the latter was traveling around the word at the request of his wife Lisa. No mention of Julia is ever made.

When Dracula started his campaign to eradicate humanity, Hector and Isaac sided with him in earnest, having experienced first-hand how cruel humans could be. As such, Dracula holds them in higher esteem than the Vampire Nobles of his court, who follow him because of his might and to feed on humans.

Isaac is very close to Dracula, who regards him as the closest thing he has to a friend, and his only truly loyal general. He and Hector use their Devil Forgery to raise the dead and turn them into monsters for Dracula's army. Dracula confides in him that he knows that his generals are turning on him, worried that his goal is insane and will leave them with no-one to feed on. He admits that he lied to them about only wanting to reduce numbers, but Isaac does not care.
