Shevaun Haldane was the daughter of
Ranulph Haldane, one of the seven members of Mys-Tech which sold their souls to the
Hell-Lord,
Mephisto for immortality. Ranulph and the others agreed to supply Mephisto with souls for extended lives. While working upstairs in the laboratories of Mys-Tech, Shevaun heard a ruckus coming from downstairs in her father’s secret laboratory.
Dark Angel, Albion and Ultra Marine
She rushed to her father’s side moments after he was killed by Mephisto. She was approached by the Angel of Death,
Dark Angel, guardian of souls who leave the mortal plane via the portal of death. The Dark Angel had arrived too late to claim Ranulph's soul. He disclosed the truth about her father's activities and later offered her a shred of the fabric of the universe, thus granting her the great power to oppose the sinister Mys-Tech. The
Angel also gave her body armor that would help her command her new powers. Realizing that she now had the power of angels to fight Hell on Earth, she took the name Hell's Angel. Shevaun would latter change her name to Dark Angel.
