His unholy bride.

Dracula had given up running from Van Helsing.

He was going to stop that meddling man once and for all.

So he laid a simple trap Van Helsing could not ignore.

He sprung his trap and caught Van Helsing.

But instead of killing him or turning him into a vampire he decided to turn him into his unholy bride.

So with the aid of his dark science he transplanted van helsing's brain into the body of a beautiful young farm girl and once he was awake and saw what had happened to him Dracula turned him into his unholy bride & the queen of the undead.
