Whistler's normal life was ripped to shreds the day his wife and two daughters were tortured and killed by a vampire disguised as a drifter. Left alive to live with his pain, Whistler dedicated himself from that day forward to the eradication of all vampires. To this end he allied himself with Blade whose similar mission and supernatural powers made him a perfect partner. Now, providing Blade with both the serum that holds off his blood lust and the Vampire Hunter's arsenal, Whistler can take a more active role in vampire extermination.
