The Impossibles were a trio of rock and roll musicians. When contacted by "Big D" about criminal activities in Empire City, they became superheroes. Like the Monkees, the group’s appearance (in their musician form) was based on 1960s pop star stereotypes, which included somewhat long hair, brightly colored (and matching) outfits, high-heeled boots, screaming female fans and, unlike the Monkees, no percussion or bass instruments. Nothing is known about their personal lives, although Fluid-Man once mentioned having an Aunt Tilly. They seemed to have secret identities though even a little child would have no trouble connecting the singing Impossibles to the hero Impossibles on appearance alone. They also seemed to change to their "secret identities" in front of the crowds they were playing to when given a mission.
