A Bokor (or Bocor) is a practicioner of black magic and a priest of the Voodoo religion. Bocor is also the name of an evil spellcaster from the Mobfire limited series.
A Bokor is a sorcerer for hire in the religion of voodoo who is said to work with both hands, meaning that they can both practice dark magic and benevolent magic . They are featured in many Haitian tales and are often associated with the creation of zombies by the use of a deadening brew or potion usually containing non-fatal poisons. This potion makes the drinker appear to be dead and thus is often buried; days later, the bokor will return for the "corpse" and force it to do his bidding, such as manual labor.
