While the game really didn’t suggest that Dracula would appear at the end, (surprise surprise) he’s the final boss and the father of the game’s hero Alucard. Alucard helped Trevor Belmont kill him the first time, and I guess he was just a wee bit mad about that.
This is honestly one of my least favorite Dracula fights in the whole series. As amazing and clever as Castlevania: Symphony of the Night is, all he does is sit in this big monster chair. What a lazy boy.
His endurance is pretty freaking crazy. I don’t remember getting close to death against him but it took forever to kill Dracula.
When Alucard sends his father to his doom, the vampire king asks what his late wife said when she died and Alucard told him that she didn’t want him hating humans, especially hurting them. Dracula seems to accept it and then dies. And I’m pretty sure he came back at least once before his permanent demise in 1999 and I don’t think he was pro-human during those times…
