What We Want To See From Castlevania Season 4
4. Isacc's Quest For Revenge
Having dispelled the evil magician, Isaac can now plan his ultimate revenge against Hector and the rest of Dracula's betrayers. The Devil Forgemaster has proven to be one of the show's most compelling characters, helped in no small part by some outstanding voice work from Adetokumboh M'Cormack. He shared Dracula's ambition to wipe out humankind, a species that he despises - even if some individual humans fascinate him. With a rapidly growing army of night creatures, Isaac is on the warpath headed to Styria, and is surely going to throw Carmilla's plan for an empire into at least temporary disarray.
Isaac has already killed a vampire, and on the whole seems a far superior fighter to Hector. It seems entirely possible that his great battle against his fellow Forgemaster and the Council of Sisters could form the climax to the fourth season. Just who will prevail in such a battle is anyone's guess.
