 Mirage's powers are of illusion-casting.Boom and Mirage steal a lot of money; Boom claims it's for supporting his grandmother.While it is implied that Boom's aggressive personality may have been the result of his exposure to Big-Bang gas (as Mirage reveals to Static that her brother never acted like that before), Mirage keeps her own personality and becomes increasingly disturbed by Boom's actions (as Boom's Quantum Vapour-exposure may have just brought out a worse side of him he had just never shown before).
