Zampire

The Zampire is the result of many years of necromantic studies and dumb luck. When a vampire bites a zombie, or when a zombie bites a vampire, the result is a creature so terrible, it has been shrouded in secrecy for almost a millennia.

The zampire is stronger than a regular vampire, and dumber than a zombie. It is now well known that when a zampire is vanquished, he comes back as a black and white version of a zombie. Why black and white? Why not.
