When Mirage rescued Brightwind, she became a valkyrie, and became endowed with the Valkyrie power to perceive and sense the coming of Death. As such, Mirage could perceive a "deathglow" surrounding a person in serious danger of dying, a dark cloud or graphic visual image over people who were in mortal peril. She could also perceive Death incarnate and even do physical battle with Death itself to stave off mortality for a short time. She has created an illusory "Cheyenne ghost-staff" drawing upon an image in her own mind and has successfully wielded it as a weapon against Death and the Asgardian death-goddess Hela.
