Dark Prince is an evil counterpart of Prince of Persia

Description: The Dark Prince is an evil counter part who's personality was derived from the Princes dark side shown in the Warrior Within. He is stronger, faster, more aware and aggressive but constantly loses health, which is fully replenishes every time he receives a sand. Water transforms him back to the normal Prince (or in one case where the Prince's Willpower turned him back to normal in the well).
