The Ravagers

Viktor's offspring inherit not only his uncharted metamorphism, but his lunacy, as well. Most of them seem docile enough until the madness fully takes hold -- usually around the same time they reach puberty or, at the very latest, when they stop aging. They then become dangers to themselves and others; flying into fits instigated by rage or hunger or any number of other things. If not put down a Ravager will, in time, degenerate to a state similar to Viktor's last. An ever-changing blob of flesh that does nothing but consume.

Nobody knows exactly how many children Viktor sired before he was put down, but his offspring are mercilessly hunted and killed by the other Predators, who seek to erase his taint.

One of the more notable traits of a vampire that has succumbed to the Insanity is the curious fact that their bite is virulent. Should they attack a person, and leave said person alive, but bitten, that person will become infected with the Insanity. Temporarily of course, but until it wears off they're just as dangerous as any Ravager.
