As the Bomb Hybrid, Reze's transformation is that of an atomic bomb, mostly reminiscent of the Fat Man atomic bomb which exploded over Nagasaki in the last moments of the Second World War. Consistent with other hybrid transformations, her teeth are always visible and are notably sharp and angular. Bomb fuses cover her arms like sleeves while also making up a portion of her apron along with sticks of dynamite. Her clothes vary during her attempt to retrieve Denji.
