Macbeth (マクベス Makubesu), formerly codenamed Midnight (ミッドナイト Middonaito), was a Dark Mage of the Oración Seis: a Dark Guild composed of highly powerful Mages whose goal was to find a Magic known as Nirvana, a very destructive power that was sealed away long ago. After the rebirth of the Oración Seis, Macbeth referred to himself as Brain II. He later joined Crime Sorcière as an Independent Mage after his escape from prison, per Jellal's request to help him take down Zeref.
