Due to complications in the construction of the carbon copy, their results gave birth to a monstrous menace, Bizarro.Bizarro has a reputation on the streets of Metropolis that is the polar opposite of Superman's. With freeze vision, flame breath, and strength to match Superman's, Bizarro is a daunting enemy. Kryptonite, which can cripple Superman, actually gives Bizarro strength, giving him an advantage over Superman.
