>>89649968I think the canon story was told years later with the Playstation 2 games. The first Belmont was Leon Belmont who was friends with an alchemist who'd later become Dracula. The alchemist basically created the Vampire Killer whip to help Leon defeat the local vampire lord who was terrorizing the town. However, the alchemist wanted to steal his vampire powers in order to take revenge on the vampires who killed his wife.
So basically the canon story was that originally Dracula and the Belmonts were friends until this event happened, which turned them into enemies.
