Julian Sands, the Warlock.
A Warlock is the term attributed to a male witch. Aside from gender distinction, there is no real difference between witches and warlocks and both have been presented as originating from different paradigms and gifted with a wide variety of powers and skills. Warlocks have been shown practicing the arts of both black magic and white magic. A warlock was the central antagonist of the Warlock film series as played by Julian Sands and later, Bruce Payne. Warlocks also played a key role in the Charmed television series. The very first adversary of the Charmed Ones was a serial killer warlock named Jeremy Burns.
